Interpretation of Substantive and Adjective Statutes

Two, the reach of section 6 of the General Clauses Act

Section 6 saves, on a repeal, any right, privilege, obligation or liability acquired, accrued or incurred under the repealed enactment, together with proceedings and remedies in respect of them. What is saved is the substantive position. The procedure by which the saved right is enforced is ordinarily the procedure now in force, subject to whatever the repealing Act itself provides. That is worked in [Repeal of Statutes, and the Provisions Dealing with Repeal under the General Clauses Act].

Three, the treatment of limitation

Limitation is the classic borderline case and it is worth two sentences.

Section 3(1) of the Limitation Act 1963 requires the court to dismiss a suit, appeal or application made after the prescribed period, although limitation has not been set up as a defence. That bars the remedy and leaves the right standing, which is why a time-barred debt paid voluntarily is validly paid. On that footing limitation is procedural.

But section 27 provides that at the determination of the period limited for a suit for possession of property, the right to the property itself is extinguished. That is substantive, because a right disappears.

The consequence: an amendment shortening a period of limitation is not applied so as to destroy a claim that has already accrued and for which time has begun to run, without clear words, because that would take away a vested right under the cover of a procedural change.

Four, the mandatory and directory question

A procedural rule is ordinarily not construed as mandatory where the defect can be cured at a later stage, which is one of the propositions in Sharif-Ud-Din v. Abdul Gani Lone, AIR 1980 SC 303, worked in [Interpretation of Directory and Mandatory Provisions]. Substantive conditions on the acquisition of a right are more often mandatory.

How a court classifies a provision

Four questions, in order.

One, does the provision create, define, transfer or extinguish a right or a liability? If yes, substantive.

Two, does it only prescribe the manner of enforcing a right that exists independently of it? If yes, procedural.

Three, does it, though procedural in form, take away or impair a vested right? If yes, it is treated as substantive for the purpose of retrospectivity, whatever it is called. A provision abolishing an existing right of appeal is the standard example: an appeal is procedure, and the right of appeal has been treated as a substantive right which vests when the proceeding is instituted.

Four, has the legislature said what it intends? An express provision governs, subject to the Constitution.

The third question is the one that carries the marks, because it prevents the classification from being decided by the label.

The forms of statute this produces

Wholly substantive: the Transfer of Property Act 1882, the Indian Contract Act 1872, the Hindu Succession Act 1956, the Bharatiya Nyaya Sanhita 2023.

Wholly or mainly procedural: the Code of Civil Procedure 1908, the Bharatiya Nagarik Suraksha Sanhita 2023, the Bharatiya Sakshya Adhiniyam 2023, the Limitation Act 1963.

Mixed, and most Acts are: a welfare statute confers a right, prescribes how it is claimed, and creates an offence. Each provision is classified on its own, exactly as the rules of construction in [Taxing Statutes, Penal Statutes and Welfare Legislation] are chosen provision by provision.

Two further points that answer a question directly.

A procedural code is construed as a handmaid of justice. A rule of procedure exists to enable a case to be decided on its merits, so a construction that defeats a claim on a technicality is disfavoured, and a court has power to permit amendment and to condone irregularity. That is why section 151 of the Code preserves the inherent power of a civil court to make such orders as are necessary for the ends of justice.

A procedural provision cannot enlarge or destroy a substantive right. Order VII rule 11 rejects a plaint that discloses no cause of action; it does not decide that the plaintiff has no rights.

A worked example

Sadaf's cause of action accrues on 1 March 2024, when a builder fails to hand over her flat. In June 2026, before she has filed anything, an amending Act makes three changes.

Amendment A reduces the compensation payable for delay from twelve per cent to six per cent per year.

Amendment B transfers all such disputes from the civil court to a new tribunal, and prescribes a fresh form of application.

Amendment C reduces the period of limitation for such claims from three years to one year, with effect from the date of the amendment.

Amendment A: substantive. It changes the amount of the right itself. It is presumed prospective, so on Vatika Township it does not reduce compensation for a delay that had already occurred, since that would modify an accrued right and impose a detriment. Sadaf's claim for the period before June 2026 is at twelve per cent unless the amendment says otherwise in terms.

Amendment B: procedural. It changes the forum and the form. Nobody has a vested right in procedure, so Sadaf files before the tribunal in the new form, and a claim already pending before the civil court would ordinarily be transferred. Had Amendment B abolished the right of appeal that existed when she instituted, the analysis would change, because a right of appeal has been treated as vesting when the proceeding begins.

Amendment C: procedural in form, substantive in effect. A period of limitation ordinarily bars the remedy and so looks procedural. But applying a one-year period from June 2026 to a cause of action of March 2024 would extinguish a claim that was alive, which takes away a vested right under cover of a procedural change. Without clear words, the court will not read it that way; the usual solution is that the shorter period runs from the date the amendment comes into force, leaving the claimant a reasonable opportunity.

Notice the method. The label on the provision decided nothing. What decided each answer was whether it touched the right or only the machinery, and whether, although procedural in form, it destroyed something already vested.

Distinctions table

What this does NOT mean

Procedural does not mean unimportant. A limitation period decides cases.

Procedural does not mean always retrospective. Where a provision procedural in form takes away a vested right, it is treated as substantive for that purpose.

The name of the Act does not decide it. The Code of Civil Procedure contains substantive provisions, such as section 9 on the jurisdiction of civil courts over suits of a civil nature; the Limitation Act contains a substantive provision in section 27.

"No vested right in procedure" is not a rule that a litigant has no rights. It means the litigant has no right to any particular machinery, not that the claim can be defeated by a change of machinery.

A procedural provision cannot create a substantive right. Nor can it destroy one, and a construction that has that effect is a signal that the provision has been misclassified.

Limits and criticism

The line is not clean and the cases show it. Limitation, the right of appeal, and rules of evidence about the burden of proof all sit on the boundary, and each has been argued both ways.

Calling a change procedural is a route to retrospectivity. A legislature or a litigant seeking retrospective effect will describe the amendment as procedural, and the court's only protection is the third question above: does it, in substance, take away a vested right?

"Handmaid of justice" is a slogan that can be used to excuse non-compliance. Procedural rules exist for reasons, and Sharif-Ud-Din shows a court refusing to treat a requirement as curable where the statute itself prescribed dismissal.

Quick revision

Substantive: creates, defines, transfers or extinguishes rights and liabilities. Adjective or procedural: prescribes how they are enforced. Test: take the courts away and see what is left.

Consequences: a substantive amendment is presumed prospective; a procedural amendment applies to pending proceedings, because there is no vested right in procedure, which is the reason Vatika Township gives for treating procedure as retrospective. General Clauses Act s.6 saves the substantive position on a repeal. Limitation Act s.3 is procedural, barring the remedy; s.27 is substantive, extinguishing the right. A procedural rule is ordinarily not mandatory where the defect can be cured later, Sharif-Ud-Din.

Classification: does it create or extinguish a right; does it only prescribe the manner of enforcement; does it, though procedural in form, take away a vested right, as with a right of appeal; and has the legislature said what it intends.

MU prints "adjunctively", which means adjective, that is, procedural.

Test yourself

1. Distinguish substantive from adjective law, and give a test.

Substantive law determines the rights and liabilities of persons: what a person owns, what a contract obliges them to do, what conduct is an offence, what compensation is payable. Adjective or procedural law prescribes the machinery by which those rights are asserted and enforced: which court, in what form, within what time, on what evidence and with what appeal. A useful test is to take the courts away and ask what is left: the rules that would still make sense without courts are substantive, and those that exist only because there are courts are procedural.

2. Why does the distinction matter for retrospective operation?

Because different presumptions attach. A substantive amendment is presumed prospective and is not read as disturbing rights already accrued or transactions already completed, since it modifies vested rights or imposes new obligations. A procedural amendment applies to pending proceedings, because nobody has a vested right in procedure: a litigant is entitled to have their dispute decided, not to have it decided by the particular machinery in force when they began. Commissioner of Income Tax v. Vatika Township Private Limited gives that as the justification for treating procedural provisions as retrospective.

3. Is a law of limitation substantive or procedural?

It is ordinarily procedural, because section 3(1) of the Limitation Act 1963 bars the suit, appeal or application and leaves the right standing, which is why a time-barred debt paid voluntarily is validly paid. Section 27 is the exception and is substantive: on the determination of the period limited for a suit for possession of property, the right to the property itself is extinguished. The practical consequence of the distinction is that an amendment shortening a period will not, without clear words, be applied so as to destroy a claim that has already accrued.

4. Is a right of appeal procedural?

An appeal is procedure in form, and the right of appeal has been treated as a substantive right for the purpose of retrospectivity, vesting when the proceeding is instituted. So an amendment abolishing or restricting an appeal is not applied to a proceeding already begun unless the legislature has said so. This is the clearest illustration of the third classification question: a provision procedural in form which takes away a vested right is treated as substantive for that purpose, whatever it is called.

5. What does "a procedural code is the handmaid of justice" mean, and what is its limit?

It means that rules of procedure exist to enable a case to be decided on its merits rather than to defeat claims on technicalities, so a construction that permits amendment, condones irregularity and lets the dispute be tried is preferred, and section 151 of the Code of Civil Procedure 1908 preserves the court's inherent power to make orders necessary for the ends of justice. The limit is that procedural rules exist for reasons and are not dispensable at will: where the statute itself prescribes the consequence of non-compliance, as section 94(1) did in Sharif-Ud-Din, the requirement is mandatory and the maxim does not save the defaulter.

6. How would you classify section 9 of the Code of Civil Procedure 1908?

Although it sits in a procedural code, section 9 is substantive in character: it provides that the courts shall have jurisdiction to try all suits of a civil nature except those of which their cognizance is expressly or impliedly barred, and so it determines whether a right is justiciable at all rather than merely how it is to be pursued. It illustrates the point that the name of the Act does not decide the classification, and that each provision is classified by what it does.
