LLM Group 2 Business Law Global Trade Under World Trade Organisation 2016 Question Paper with Solutions

Article VIII confers legal personality and the necessary privileges and immunities. Article IX:1 provides for decision by consensus, with a vote only if consensus cannot be reached; Article IX:2 gives the Ministerial Conference and General Council exclusive authority to adopt interpretations, by three fourths; Article IX:3 permits waivers by three fourths; Article X governs amendment, with the most favoured nation provisions of Article I of GATT, Article II:1 of GATS and Article 4 of TRIPS amendable only with the acceptance of all members.

The bodies, tier by tier. The Ministerial Conference of all members, meeting at least every two years, competent on all matters. The General Council of all members, discharging its functions between sessions and convening also as the Dispute Settlement Body under Article IV:3 and as the Trade Policy Review Body under Article IV:4. Three sectoral Councils under Article IV:5, for Trade in Goods, Trade in Services and TRIPS, with subsidiary committees under Article IV:6.

Two of the five deserve expansion because they are what the organisation actually does most days. Dispute settlement has handled more than six hundred and thirty disputes since 1995, against roughly three hundred in GATT's entire forty seven years. The Trade Policy Review Mechanism in Annex 3 subjects every member's whole trade regime to periodic collective examination on the basis of two reports, one by the government and one by the Secretariat, at intervals graduated by share of world trade, the four largest traders every three years and others less often. It creates no obligations and imposes no remedies; its value is publicity and internal discipline, since a government must explain its own protection to itself before it explains it in Geneva.

Examining the role in promoting global trade: the case for

The tariff and predictability record is very strong. Average bound industrial tariffs in developed members are under four per cent after the Uruguay Round commitments, from about forty per cent in 1947, and the great majority of world tariff lines are now bound, which converts protection from a discretionary act into a legal commitment. World merchandise trade grew from about five trillion dollars in 1995 to well over twenty trillion by the mid 2020s, and commercial services trade from about one to more than seven trillion.

Specific institutional achievements should be named. The phase out of the Multi Fibre Arrangement quotas by 1 January 2005 under the Agreement on Textiles and Clothing. The first discipline on agriculture in the system's history. The Trade Facilitation Agreement, agreed at Bali in December 2013 and in force 22 February 2017, the first multilateral agreement concluded under the WTO, on customs procedures, with implementation sequenced to each developing member's own notified capacity. The Agreement on Fisheries Subsidies, adopted in June 2022 and in force 15 September 2025 on acceptance by two thirds of the membership, the first WTO agreement with environmental sustainability at its core. And the elimination of agricultural export subsidies by the Nairobi Ministerial Decision of 19 December 2015.

The Fourteenth Ministerial Conference is the clearest single piece of evidence. Held at Yaoundé, Cameroon, from 26 to 30 March 2026, it closed without a ministerial declaration; the moratorium on customs duties on electronic transmissions, renewed at every conference since 1998, expired on 31 March 2026; and sixty six members endorsed an E-Commerce Agreement outside the multilateral framework. The pattern of the last decade is the migration of rule making to plurilateral arrangements and to regional agreements, of which over three hundred and fifty are in force and notified, so that a large and growing share of world trade moves on preferential rather than most favoured nation terms.

The development criticism is separate and it is India's. The Uruguay Round bargain gave developing members TRIPS and GATS obligations from 1995 and back loaded their textile gains to 2005; special and differential treatment provisions are mostly hortatory; implementation issues raised in 2001 are unresolved; the public stockholding question, protected only by the Bali peace clause of 7 December 2013 and the General Council decision of 27 November 2014, still has no permanent solution and was again unresolved at Yaoundé; and only one dispute in thirty years has ever been brought by a least developed member.

The pattern repeats at every scale. Vietnam acceded in 2007, Saudi Arabia in 2005, Russia in 2012 after eighteen years of negotiation, and Timor-Leste and Comoros at Abu Dhabi in February 2024. Around twenty two governments remain in accession, and none has withdrawn its application on the ground that membership is not worth having.

And the negative test is equally telling. Article XV of the Marrakesh Agreement permits withdrawal on six months' notice, and no member has ever exercised it. For an organisation frequently described as failing, thirty six voluntary entries at heavy legislative cost and zero exits is a fact any assessment has to accommodate. It does not answer the criticism that the WTO can no longer make rules; it does establish that the rules it already administers are valued by the governments bound by them.

Conclusion. The WTO is composed of one hundred and sixty six members and of the bodies they staff themselves, from the Ministerial Conference through a General Council that is simultaneously the Dispute Settlement Body and the Trade Policy Review Body, to three sectoral Councils and their committees, served by a Secretariat with no power to decide. Its functions under Article III are administration, negotiation, dispute settlement, trade policy review and cooperation with the Bretton Woods institutions.

For full marks, cover: what the two functions are and where each is located in the treaty; why the legislative function seized up and the judicial one did not; the ways in which adjudication then did legislative work, with named examples; the criticisms that followed and the two American objections in particular; the consequence, which is the destruction of the appellate tier; and a reasoned view.

The proposition is true, it is the deepest structural problem in WTO law, and it is best stated as a mismatch of decision rules. The WTO's legislative function requires consensus: Article IX:1 for decisions, Article IX:2 for authoritative interpretations by three fourths, Article IX:3 for waivers by three fourths, Article X for amendments, with the most favoured nation provisions amendable only with the acceptance of every member.

Two structural features explain it. The membership grew from one hundred and twenty eight to one hundred and sixty six, so the cost of a single objection fell to almost nothing. And the single undertaking made everything hostage to everything: nothing is agreed until all is agreed, so a stalemate in agriculture stalls services, and a stalemate anywhere stalls the round.

The interpretive escape valve has never been used. Article IX:2 exists precisely so that members can correct an interpretation they dislike, by three fourths, without amending the treaty. It has never once been invoked. That is the single most telling fact in this answer: the members possessed a legislative answer to any judicial overreach and did not use it, and the reason is that three fourths of a hundred and sixty six members is itself unattainable when the interpretation favours some of them.

How adjudication filled the space

The panels and the Appellate Body decided over six hundred and thirty disputes and, in doing so, settled questions the negotiators had left open. Some examples, each of which is now black letter law and none of which is in the treaty text in those terms.

Zeroing. In a long line beginning with European Communities: Anti-Dumping Duties on Imports of Cotton-Type Bed Linen from India, WT/DS141/AB/R, adopted 12 March 2001, brought by India, and continuing through United States: Softwood Lumber V and the American zeroing cases, the practice of treating negative dumping margins as zero was held inconsistent with Article 2.4.2. India won in Bed Linen. The word "zeroing" appears nowhere in the Anti-Dumping Agreement.

The Enabling Clause. In European Communities: Conditions for the Granting of Tariff Preferences to Developing Countries, WT/DS246/AB/R, adopted 20 April 2004, brought by India, the Appellate Body held that the Enabling Clause is an exception to Article I:1 which the respondent must invoke and justify, and that a preference scheme may differentiate between developing countries only in response to a development need assessed by an objective standard. India won. The 1979 Decision says none of that expressly.

The criticisms, stated fairly

The overreach criticism. Where negotiators deliberately left a text ambiguous because that was the only way to agree, an adjudicator that resolves the ambiguity has made law that the members declined to make. Article 3.2 and Article 19.2 of the DSU both say expressly that findings and recommendations cannot add to or diminish the rights and obligations provided in the covered agreements. The critics say that in zeroing, in trade remedy standards of review, and in the treatment of public bodies and of subsidies to state owned enterprises, that limit was crossed.

The particular American objections should be given, because they explain the outcome. The United States has objected since 2017 to: persons continuing to serve on a division after their terms expired, under Rule 15 of the Working Procedures; the issuing of advisory opinions on matters not necessary to resolve the dispute; the treatment of prior reports as binding precedent; appellate findings on the meaning of a member's own domestic law and on facts, contrary to Article 17.6; and systematic failure to keep to the ninety day limit in Article 17.5. Whatever one makes of them, they are objections about the boundary between adjudication and legislation.

What has replaced it is instructive. The Multi-Party Interim Appeal Arbitration Arrangement, notified in April 2020 and now with over fifty participants, reproduces an appeal by consent under Article 25 arbitration; India and the United States are not participants. And rule making has moved to plurilateral instruments: the December 2021 Reference Paper on Services Domestic Regulation agreed by sixty seven participants, and the E-Commerce Agreement endorsed by sixty six members at Yaoundé in March 2026. In other words, both functions are now being performed by coalitions of the willing rather than by the organisation, which is exactly the fragmentation the single undertaking was designed to end.

Conclusion. The imbalance is real and it is written into the treaty as a mismatch of voting rules: legislation needs consensus and adjudication needs the absence of consensus, so one function was always going to outrun the other. Over thirty years adjudication settled the meaning of the Article XX chapeau, the relevance of health risk to likeness, the illegality of zeroing, the conditions of the Enabling Clause and, in effect, the existence of precedent, while negotiation produced two agreements and an unfinished round.

For full marks, cover: the comparison, which means saying first what is the same, because most candidates only list differences and the continuity is half the truth; then the differences under headings; then the legal relationship between GATT 1947, GATT 1994 and the WTO, which is where the marks separate.

What is the same, and it is more than the differences

The substantive rules of world trade law were drafted in 1947 and have never been rewritten. Articles I on most favoured nation treatment, II on schedules of concessions, III on national treatment, VI on anti-dumping and countervailing duties, XI on the elimination of quantitative restrictions, XII and XVIII:B on balance of payments restrictions, XVI on subsidies, XIX on emergency safeguard action, XX on general exceptions, XXI on security, XXIII on nullification and impairment and XXIV on customs unions and free trade areas are, word for word, the operative provisions of GATT 1994.

The Appellate Body held in Brazil: Measures Affecting Desiccated Coconut, WT/DS22/AB/R, adopted 20 March 1997, that GATT 1994 is a legally distinct instrument from GATT 1947, so that a countervailing duty investigation begun before 1 January 1995 could not be judged under the SCM Agreement or GATT 1994. The Philippines lost. The proposition "the WTO replaced GATT" is therefore imprecise: the WTO succeeded GATT as an institution and re-enacted its text as one of several covered agreements.

Two consequences follow. First, GATT 1994 is now only one of about twenty covered agreements, so a measure may breach GATT and a specific agreement at once, and Annex 1A's General Interpretative Note gives the specific agreement precedence in case of conflict. Second, GATT era panel reports are persuasive but were adopted under a different regime, and their weight depends on whether the provision they construed survived unchanged.

The two rows of the table that carry the most weight, and one that reads as a difference and is not

The row that matters most is dispute settlement, and the reason is that every other difference is only as good as its enforceability. Under GATT a panel was established by consensus of the CONTRACTING PARTIES and its report adopted by consensus, so the respondent could veto either step; under the DSU each step happens unless the DSB decides by consensus not to act, which makes it automatic. The consequence can be stated with a single pair of facts: roughly three hundred complaints were handled in GATT's forty seven years, of which several significant reports were never adopted, and more than six hundred and thirty disputes have been filed in the WTO's thirty, with a high compliance rate. The two unadopted Tuna Dolphin reports of 1991 and 1994 are the standing proof of the old defect.

The row that matters second is the form of obligation. The Tokyo Round's nine codes bound only their signatories, so the same conduct could be lawful against one trading partner and unlawful against another, and a member could accept the customs valuation code and decline the subsidies code. The single undertaking of Annexes 1 to 3 ended that, and it is what made GATS and TRIPS possible: neither could have been imposed as an optional code on a membership that had spent the 1980s resisting them.

Conclusion. GATT and the WTO share their substantive law, their negotiating technique, their membership and their institutional practice, and the Marrakesh Agreement says so in Article XVI:1. They differ in that GATT was a provisional agreement without legal personality, covering goods alone, with obligations fragmented across optional codes, with a grandfather clause preserving inconsistent domestic law, with agriculture and textiles carved out, and with a dispute procedure the respondent could veto; while the WTO is an organisation with personality, three pillars of coverage, a single undertaking, an obligation to conform domestic law, disciplines on agriculture and the abolition of textile quotas and grey area measures, and a compulsory dispute procedure with time limits and an appeal.

Legally, GATT 1947 was terminated and re-enacted as GATT 1994, a distinct instrument as Brazil: Desiccated Coconut holds, and now one covered agreement among twenty. The truest single sentence is that the Uruguay Round changed almost nothing about what world trade law says and almost everything about whether it can be enforced, and that since December 2019 the second half of that achievement has been partly undone.

The challenges

One: cost, in money. A full WTO case involves consultations, two rounds of written submissions, two hearings, an interim review, frequently an appeal, then a compliance panel and an arbitration on the level of retaliation. Outside counsel in Geneva or Washington bill at rates that put a single case in the range of hundreds of thousands to several million dollars. For a member whose entire mission in Geneva is two or three diplomats covering the WTO, the World Intellectual Property Organization, the World Health Organization and the International Labour Organization, that is not a budget line.

Two: cost, in capacity. Litigation requires an institutional apparatus most small members do not have: officials who can identify a violation from customs data, a domestic industry able to document injury, an inter ministerial process able to decide to sue a trading partner, and lawyers who know the case law. The Advisory Centre on WTO Law was created precisely because this gap could not be closed by fee subsidies alone.

Five: delay. The design limit in Article 20 is nine to twelve months; the reality is more than two years to adoption and often five or more to compliance. A firm in a small economy with a single product line may not survive the case it wins.

Six: the systemic asymmetry of information and precedent. Reports run to hundreds of pages and the jurisprudence is now enormous. Members that litigate constantly accumulate expertise; members that litigate once a decade start again each time. Since the Appellate Body treats its own reasoning as effectively binding, as it said in United States: Stainless Steel (Mexico), WT/DS344/AB/R, adopted 20 May 2008, the law is made in cases the small members are not in.

Seven, and now decisive: there is no appellate tier. Since 30 November 2020 the Appellate Body has had no members. A developing member that wins before a panel may find the respondent appeals into the void, so the report is never adopted and no obligation arises. The Multi-Party Interim Appeal Arbitration Arrangement offers a substitute only between its own participants, and the two largest respondents in the system, the United States and India, are not among them. This has converted the access problem into something worse: even a member with capacity, money and a good case may be unable to obtain an enforceable outcome.

The assessment is that these are almost all procedural and hortatory. They adjust timetables and require statements; none of them reduces the cost of litigation, and none of them makes the remedy usable by a small economy. Article 12.11 has produced formulaic recitals. The one provision with real bite is Article 8.10 on panel composition.

Strategies: what a developing member can do for itself

Use the Advisory Centre on WTO Law. Established by an agreement of 1999, operating from Geneva since 2001, funded by an endowment and by member contributions, it provides legal advice, training and representation in disputes at subsidised hourly rates on a sliding scale, free for least developed countries. It has appeared in a large number of disputes for developing members. Joining it is the single cheapest capacity decision available.

Build domestic capacity and institutionalise it, which is what India did and it is the model. India created the Trade Policy Division in the Department of Commerce, the Centre for WTO Studies at the Indian Institute of Foreign Trade as a permanent research arm, and the Directorate General of Trade Remedies in May 2018 by merging the anti-dumping, safeguard and countervailing functions.

Use the cheaper parts of the system. Consultations settle a large share of disputes and cost comparatively little. Article 5 good offices, conciliation and mediation by the Director General are available at any time. Article 25 arbitration is available by agreement. And a well drafted request for consultations, circulated to the DSB, has diplomatic value even if it is never pursued, which is precisely how India used DS503 on American visa fees.

Choose cases for their systemic value. Bed Linen and Tariff Preferences were worth far more than the trade at issue because they changed the law for everyone. That is the highest return available on a limited litigation budget.

Strategies: what the system must change

Restore the appellate tier, or generalise the substitute. Nothing else matters as much. Either appointments are unblocked, or the MPIA becomes universal, or Article 25 arbitration becomes the standard route. As long as an appeal into the void is available, a developing member's victory is provisional at the respondent's option.

The case that proves a developing member can win, worked out

The strategies above are worth nothing unless a developing member has actually used them successfully. India has, and this is the case.

European Communities: Conditions for the Granting of Tariff Preferences to Developing Countries, WT/DS246/AB/R, adopted 20 April 2004.

The facts. The European Communities operated a Generalized System of Preferences with several tiers. One of them, the special arrangements to combat drug production and trafficking, gave duty free access on a wider range of products than the general scheme, and it was available to twelve named countries in Latin America and Pakistan. There were no published criteria for entry, no procedure by which a country could apply, and no mechanism for leaving. India, whose exports competed with those twelve in the European market, complained that the arrangement discriminated between developing countries contrary to Article I:1 of GATT 1994 and was not saved by the Enabling Clause.

Why it answers this question. It is the only judicial statement of the limits of a development exception, and it was obtained by a developing member against the largest preference granting bloc in the world, on a scheme designed to be generous. It shows that the obstacle for developing members is capacity rather than doctrine: India could bring it because it had built the institutional apparatus described above, and the countries most harmed by preference discrimination, the least developed, still have not brought a comparable case.

Conclusion. The challenges are not formal but practical: the cost of litigation in money and institutional capacity, a remedy that is prospective and retaliatory and therefore unusable by a small economy, the fear of losing preferences or goodwill, delay of two to five years, an accumulating jurisprudence made in cases small members are not party to, and, since 30 November 2020, no appellate tier at all, so that even a won case can be suspended indefinitely by an appeal into the void. The DSU's special and differential treatment provisions, Articles 4.10, 8.10, 12.10, 12.11, 21.2, 21.7, 21.8, 24 and 27.2, adjust procedure and do nothing about cost or remedy.

For full marks, cover: the textual basis, because the WTO has no environmental agreement and the whole subject runs through Article XX and two specific agreements; the case law, which is where the doctrine was made; the negotiated developments including the fisheries agreement; and then the human rights half, which most candidates leave as a paragraph of assertion and which should be answered with named rights, named cases and the actual points of conflict.

Two framing propositions. First, the WTO is not an environmental organisation and has no environmental agreement of general application; the Preamble to the Marrakesh Agreement mentions sustainable development and the protection and preservation of the environment, which the Appellate Body has used as an interpretive guide. Second, the WTO has no human rights agreement either, and no human rights jurisdiction; human rights enter as the substance of measures a member defends and as the consequence of trade rules on access to medicines, food and livelihood.

Two specific agreements do the detailed work. The SPS Agreement governs measures to protect human, animal or plant life or health from pests, diseases and contaminants in food, requiring in Articles 2.2 and 5.1 that a measure be based on scientific principles and on a risk assessment, with a provisional measure permitted under Article 5.7 where evidence is insufficient. The TBT Agreement governs technical regulations and standards, requiring in Article 2.2 that they be not more trade restrictive than necessary to fulfil a legitimate objective, which expressly includes protection of human health or safety, animal or plant life or health, and the environment. TRIPS Article 27.2 permits exclusion from patentability to avoid serious prejudice to the environment, and Article 27.3(b) the exclusion of plants and animals.

The institutional home is the Committee on Trade and Environment, created by the Marrakesh Decision of 15 April 1994, with a broad mandate and no negotiating authority; a Committee on Trade and Environment in Special Session was created by the Doha Declaration of November 2001 with a narrow negotiating mandate on the relationship with multilateral environmental agreements, on procedures for information exchange, and on the reduction of barriers to environmental goods and services. It produced nothing.

But it failed the chapeau, because the United States had negotiated seriously with some exporters and not with the complainants, had given some countries a phase in period of three years and the complainants four months, and had operated its certification without transparency, notice, reasons or any right of appeal. India and its co-complainants won. After the United States changed its administration of the scheme, the compliance panel and the Appellate Body in United States: Shrimp (Article 21.5 Malaysia), adopted 21 November 2001, held the revised measure justified. The double lesson is that the WTO does not forbid unilateral environmental measures, and does insist that they be applied with due process and even handedness.

Brazil: Measures Affecting Imports of Retreaded Tyres, WT/DS332/AB/R, adopted 17 December 2008. Brazil banned imports of retreaded tyres to reduce waste tyre accumulation and the mosquito borne disease and toxic fires associated with it. The European Communities complained. The Appellate Body held the ban capable of justification under Article XX(b), accepting that a measure contributing to a material extent to a legitimate objective as part of a comprehensive policy may be necessary even if its effect is not immediately quantifiable, but held that it failed the chapeau because Brazil exempted MERCOSUR partners under an arbitral award and because court injunctions had allowed large volumes of used tyre imports. The European Communities won on the chapeau. The case is the best authority that a quantitative ban can in principle be an environmental measure.

Two earlier decisions complete the line. United States: Standards for Reformulated and Conventional Gasoline, WT/DS2/AB/R, adopted 20 May 1996, the first appellate report, held clean air to be an exhaustible natural resource but struck the baseline rules down under the chapeau. And the two unadopted Tuna Dolphin panel reports of 1991 and 1994 had held that Article XX could not reach resources outside the importing member's jurisdiction, a position the Appellate Body effectively abandoned in Shrimp.

Two further items belong here. Plurilateral initiatives on Trade and Environmental Sustainability, on Plastics Pollution and on Fossil Fuel Subsidy Reform have been launched by groups of members outside the multilateral track. And the European Union's Carbon Border Adjustment Mechanism, adopted in 2023 with reporting from October 2023 and financial obligations from 2026, is the largest live trade and environment question: India has objected to it as a unilateral measure inconsistent with common but differentiated responsibilities and has raised it in the Committee on Trade and Environment and in the Council for Trade in Goods. Whether it survives Articles I, III and XX will be the Shrimp question of this decade.

The impact on human rights

Name the rights and the mechanisms, or this half of the answer is assertion. The rights principally engaged are the right to health, including access to medicines, under Article 12 of the International Covenant on Economic, Social and Cultural Rights; the right to food under Article 11; the right to water; the right to a healthy environment, recognised by the United Nations General Assembly on 28 July 2022; the right to development; and the rights of indigenous and traditional communities in genetic resources and traditional knowledge.

Food security is the second conflict, and it is India's. The Agreement on Agriculture's ten per cent de minimis limit on product specific support in Article 6.4(b) constrains minimum support price procurement for the public distribution system. In India: Sugar and Sugarcane, DS579 to DS581, the panel held on 14 December 2021 that India's mandatory cane prices exceeded that limit for five consecutive years; India lost and appealed on 11 January 2022 into a vacant Appellate Body. The Bali peace clause of 7 December 2013, extended indefinitely by the General Council on 27 November 2014, shields public stockholding programmes from challenge pending a permanent solution which has not been agreed and was again unresolved at Yaoundé in 2026. The right at stake is the right to food of the beneficiaries of the National Food Security Act, 2013.

For the WTO: Article XX has in fact been read generously since Shrimp and Asbestos, no environmental measure has been struck down for its objective as opposed to its administration, the Fisheries Subsidies Agreement shows the membership legislating for sustainability, and the Doha Declaration and Article 31bis show the system accommodating a health emergency. The fair conclusion is that WTO law is permissive of environmental and health regulation and demanding about how it is applied, and that its real human rights failures are in what it has not negotiated, on public stockholding and on Mode 4, rather than in what it has decided.

Conclusion. Environmental issues reach the WTO through Article XX(b) and (g) with its chapeau, through the SPS and TBT Agreements, through TRIPS Article 27, and through the Committee on Trade and Environment, and the governing doctrine was made by adjudication: United States: Gasoline, United States: Shrimp, European Communities: Asbestos, Brazil: Retreaded Tyres and United States: Tuna II together establish that a member may protect the environment and health, may do so by reference to resources beyond its own territory, and will be judged on the even handedness and transparency of the application rather than on the legitimacy of the objective.

For full marks, cover: the quotation first, and prove it, because the proposition in it is correct and demonstrable: the exceptions to MFN now cover more trade than the rule. Then answer the second question, which asks how two obligations fit together, and the answer is that they are two applications of one principle operating at different moments and limited by the same concept of likeness.

The Committee on Regional Trade Agreements has never concluded that any agreement fails Article XXIV, and in Turkey: Restrictions on Imports of Textile and Clothing Products, WT/DS34/AB/R, adopted 19 November 1999, the Appellate Body held that Article XXIV can justify a measure only if the customs union would be prevented from being formed without it, a test almost impossible to satisfy, so Turkey's quotas fell; India won. The rule is therefore strict in litigation and unenforced in practice.

Two: the Enabling Clause and the Generalized System of Preferences. The Decision of 28 November 1979 on Differential and More Favourable Treatment permits developed members to give tariff preferences to developing members without extending them to everyone.

Four: the trade remedies. An anti-dumping duty under Article VI is imposed on the products of the dumping exporters only; a countervailing duty on the products of the subsidising country only. Both are, by design, discriminatory as between sources. Only a safeguard under Article XIX must be applied irrespective of source under Article 2.2 of the Safeguards Agreement, and even there Article 9.1 exempts developing exporters below three per cent.

Five: Article XX, XXI and waivers. Measures justified under the general exceptions or the security exception may be, and usually are, applied to some countries and not others; the chapeau requires only that discrimination not be arbitrary or unjustifiable between countries where the same conditions prevail, which is a permission to discriminate where conditions differ. Waivers under Article IX:3 of the Marrakesh Agreement have licensed discrimination expressly, the Kimberley Process waiver for conflict diamonds being the clearest example.

Six: accession protocols and Article XXXV style non application. Terms of accession are negotiated individually under Article XII, so China's Protocol of 11 December 2001 imposed obligations and permitted transitional discrimination against China that apply to no other member, including the textile specific safeguard in paragraph 242 available until 31 December 2008 and the special methodology for price comparability in section 15.

Part two: reconciling MFN and national treatment

They are two limbs of one principle, and the reconciliation lies in seeing that they operate at different moments and answer different evasions. MFN, Article I, operates at the border and between foreign suppliers: a concession to one is a concession to all. National treatment, Article III, operates inside the border and between foreign and domestic products: internal taxes and regulations must not protect domestic production. Each is useless without the other. A member bound only by MFN could impose uniformly prohibitive protection. A member bound only by national treatment could admit German cars at five per cent and Japanese cars at fifty and then treat both scrupulously inside the market.

They share a common purpose, stated in the case law rather than the text: the protection of competitive opportunities. The Appellate Body has repeatedly held that neither obligation requires proof of trade effects; what is protected is the conditions of competition. That is why Article III:4's standard is "treatment no less favourable" and why Article XVII:3 of GATS says expressly that formally identical treatment is a breach if it modifies conditions of competition.

The internal structure of Article III completes the picture. Article III:1 states the purpose: internal measures should not be applied so as to afford protection to domestic production. Article III:2 first sentence forbids taxing imports in excess of like domestic products, strictly and with no de minimis. Article III:2 second sentence, read with the Ad Note, forbids dissimilar taxation of directly competitive or substitutable products where it affords protection. Article III:4 requires no less favourable treatment in laws, regulations and requirements.

Japan: Taxes on Alcoholic Beverages, WT/DS8, DS10 and DS11/AB/R, adopted 1 November 1996, applied all three: vodka and shochu were like, so the excess tax breached the first sentence without more; whisky, brandy, rum and gin were directly competitive, so the dissimilar taxation afforded protection and breached the second. The complainants won. Korea: Taxes on Alcoholic Beverages, adopted 17 February 1999, added that potential competition counts, since the protective tax will itself have suppressed the imports whose absence is relied on.

A worked case that shows both limbs at once. In Canada: Certain Measures Affecting the Automotive Industry, WT/DS139/AB/R and WT/DS142/AB/R, adopted 19 June 2000, Canada gave an import duty exemption to manufacturers meeting Canadian value added and production to sales ratio conditions. The Appellate Body held the duty exemption inconsistent with Article I:1, because in fact only vehicles from the United States and from the beneficiaries' own affiliates qualified, so Article I catches de facto discrimination; and it held the Canadian value added requirement inconsistent with Article III:4, because it gave domestic parts an advantage over imported like parts. Japan and the European Communities won on both limbs. One measure, two obligations, and the same underlying vice: protection given otherwise than by an equally applied tariff.

For full marks, cover: two notes of about twelve and a half marks each in the examination. All four are written out below. Each needs the instrument, the mechanism, an authority and a consequence.

(a) Doha Development Agenda

The Fourth Ministerial Conference at Doha on 14 November 2001 adopted a Ministerial Declaration launching a round of negotiations styled the Doha Development Agenda, and it has never been concluded. Its timing mattered: it was two months after the attacks of 11 September 2001 and two years after the collapse of the Seattle Ministerial in 1999, and the political need for a success was acute. Its name mattered too, because the developing members' price for a new round was that development be its declared object, the Uruguay Round bargain having been seen as unbalanced.

Why it failed, in four episodes. The Cancun Ministerial of September 2003 collapsed over the Singapore issues, investment, competition, government procurement transparency and trade facilitation, which the European Union pressed and developing members refused, and over the cotton initiative of four West African countries; only trade facilitation survived, by the July 2004 framework. The Hong Kong Ministerial of December 2005 fixed 2013 for the elimination of agricultural export subsidies and agreed duty free quota free access for least developed countries, and did little else.

The July 2008 mini ministerial at Geneva collapsed at the last stage over the special safeguard mechanism, the trigger at which a developing country could raise tariffs against an import surge in agriculture, with India and China on one side and the United States on the other. And at Nairobi in December 2015 the membership could not agree that the Doha mandate survived at all, the Ministerial Declaration recording expressly that members had different views on the subject.

Conclusion. The Doha Development Agenda is a round launched on 14 November 2001 with a mandate broader than the Uruguay Round's and with development as its declared purpose, which collapsed at Cancun in 2003, stalled at Hong Kong in 2005, failed at Geneva in July 2008 over the special safeguard mechanism, and was effectively abandoned at Nairobi in 2015. Its harvest is the Trade Facilitation Agreement, the Fisheries Subsidies Agreement, the abolition of agricultural export subsidies and TRIPS Article 31bis, which is more than nothing and far less than its mandate. Its failure is the primary reason WTO rule making has migrated to plurilateral and regional instruments, and the reason India's two central demands, a permanent solution on public stockholding and the extension of Article 23 to all products, remain unmet after twenty five years.

The exceptions. Article XI:2 permits export restrictions temporarily applied to relieve critical shortages of foodstuffs, import and export restrictions necessary to the application of standards, and certain agricultural measures. Articles XII and XVIII:B permit restrictions to safeguard the balance of payments, the latter on easier terms for developing members. Article XIII requires any permitted restriction to be non discriminatory, with shares allocated to supplying countries approximating those they would have had without it.

Articles XX and XXI apply. Article 4.2 of the Agreement on Agriculture forbids the maintenance of the measures that had to be converted into ordinary customs duties, which is tariffication. Article 11.1(b) of the Safeguards Agreement prohibits voluntary export restraints and grey area measures. And Article 2.1 of the TRIMs Agreement, with its Illustrative List, catches local content and trade balancing requirements that operate as restrictions.

Conclusion. A quantitative restriction is the instrument GATT prohibits outright, because a quota is opaque, rent creating, price insulating and discriminatory in administration, where a tariff is none of those things. Article XI:1 is drafted to catch any measure with a restrictive effect, and the exceptions in Articles XI:2, XII, XVIII:B, XX and XXI are narrow, subject to the non discrimination requirement of Article XIII, and, in agriculture, replaced by tariffication under Article 4.2. India's defeat in India: Quantitative Restrictions in 1999 ended the last large system of import licensing maintained on balance of payments grounds by a major economy, and it did so on the strength of a finding by the International Monetary Fund, which is Article XV:2 of GATT working exactly as the Bretton Woods designers intended.

Article 2.4.2 governs the comparison of weighted averages and is the source of the zeroing jurisprudence: treating negative margins as zero inflates the dumping margin, and the practice was condemned in European Communities: Anti-Dumping Duties on Imports of Cotton-Type Bed Linen from India, WT/DS141/AB/R, adopted 12 March 2001, in which India won, and in the long American zeroing line thereafter.

Injury and causation. Article 3.1 requires positive evidence and an objective examination of the volume of dumped imports, their effect on prices, and their consequent impact on domestic producers. Article 3.4 lists the factors. Article 3.5 requires that injury caused by other factors not be attributed to the dumped imports, which is the non attribution obligation and the ground on which many determinations fail. Article 4.1 defines the domestic industry. Article 5.8 requires immediate termination where the margin is de minimis, below two per cent, or the volume of imports from a country is negligible, normally below three per cent individually or seven per cent collectively.

In India. Section 9A of the Customs Tariff Act, 1975 with the Anti-dumping Rules of 1995, administered by the Directorate General of Trade Remedies since May 2018 and given effect by the Ministry of Finance. India has been among the world's most frequent users since the late 1990s, most heavily against chemicals, steel, plastics and fibres from China. In Reliance Industries Ltd v Designated Authority, (2006) 10 SCC 368, the Supreme Court treated the Designated Authority's function as quasi judicial and reviewable, and the courts and the appellate tribunal have insisted on disclosure of essential facts, which is the domestic counterpart of Article 6.9.

Conclusion. Anti-dumping is the remedy for injurious price discrimination by foreign producers, requiring three findings, dumping measured against normal value, material injury to the domestic industry, and a causal link with non attribution of other causes, established in a transparent investigation and expiring after five years unless reviewed. Its legal content is almost entirely about method: how normal value is constructed, how the comparison is made, and what the investigating authority must disclose. India's own contribution to the law is Bed Linen, which established that zeroing breaches Article 2.4.2, and India is simultaneously one of the heaviest users of the instrument, which is a fair reflection of its double interest as an exporter and as a producer.

The traffic light structure, and note what has lapsed. Article 3 prohibits two categories outright: subsidies contingent in law or in fact on export performance, and subsidies contingent on the use of domestic over imported goods. Article 5 makes other specific subsidies actionable where they cause injury to another member's domestic industry, nullification or impairment of benefits, or serious prejudice to the interests of another member. The former Article 6.1 presumptions of serious prejudice and the Article 8 category of non actionable subsidies both lapsed on 31 December 1999 and have never been renewed, which is a point few candidates know and which matters because it removed the green box for research, regional development and environmental adaptation subsidies.

The public body question, and India's win. Whether a state owned enterprise supplying inputs below market price makes a financial contribution turns on whether it is a "public body". In United States: Anti-Dumping and Countervailing Duties (China), WT/DS379/AB/R, adopted 25 March 2011, the Appellate Body held that a public body is an entity that possesses, exercises or is vested with governmental authority, not merely one the government owns or controls.

Article 4 provides an accelerated track for prohibited subsidies, with a shortened timetable and a remedy of withdrawal, exercised in Brazil: Export Financing Programme for Aircraft, WT/DS46/AB/R, adopted 20 August 1999, where Brazil was ordered to withdraw the PROEX interest equalisation payments within ninety days, and in the mirror case Canada: Measures Affecting the Export of Civilian Aircraft, WT/DS70/AB/R, adopted the same day, where Technology Partnerships Canada assistance was found contingent in fact on export performance. Countermeasures were later authorised against both, of about 344.2 million Canadian dollars against Brazil in 2000 and about 247.8 million against Canada in 2003, and neither was applied in full.

In India. Section 9 of the Customs Tariff Act, 1975 with the Countervailing Duty Rules, 1995, administered by the Directorate General of Trade Remedies. India uses the instrument sparingly compared with anti-dumping, and is more often a respondent to countervailing investigations abroad, which is why the public body test and the treatment of India's export promotion schemes matter so much to Indian exporters.
