Cases checked to exist. Read the judgment before quoting a holding.

Every case cited here has been checked to exist — the citation resolves and names the right parties. The propositions attributed to each case have not been verified line by line against the judgment. Case names link through to the full judgment: read it before quoting a holding in an examination answer, and never carry a proposition from notes into court on trust.

The examinable core. Unit I ends with a list of statute types, and the papers set them as 6-mark notes: “Interpretation of statutes conferring powers” and “Codifying and consolidating statutes” (January 2026), “Codified statutes” (June 2025). Mandatory and directory provisions are the one topic here big enough for a 10-mark answer. For each type, know the definition, the rule of interpretation and one authority.

1. Mandatory and directory provisions

The question is what happens when a statutory requirement is not complied with. If the provision is mandatory, non-compliance makes the act or proceeding invalid. If it is directory, substantial compliance is enough, and failure may attract some other consequence but does not nullify what was done.

There is no single test. The court looks at the whole scope and object of the statute. The factors usually weighed are:

Cases to cite:

Mandatory manner. Where a statute prescribes the manner in which a thing is to be done, it must be done in that manner or not at all (Taylor v. Taylor, 1875; Nazir Ahmad v. King-Emperor, Privy Council, 1936), applied in Babu Verghese v. Bar Council of Kerala, 1999 INSC 108, (1999) 3 SCC 422. Use this rule when the question is whether a power was validly exercised.

2. Substantive and adjunctival (procedural) statutes

A substantive law defines rights and duties: what a person may do, must do or is liable for. An adjunctival or adjectival law provides the machinery for enforcing them: procedure, evidence, limitation, forum. The distinction affects interpretation in two ways. Procedural law is read so as to advance justice, not to defeat it; procedure is the handmaid of justice (Sangram Singh v. Election Tribunal, Kotah, 1955 INSC 15, AIR 1955 SC 425), which is why procedural time limits are often directory. And procedural law presumptively applies to pending proceedings, while substantive law is presumed prospective; see the note on retrospective operation.

3. Enabling statutes

An enabling statute permits what was previously unlawful or beyond power: it enlarges the capacity of a person or authority (a statute allowing a company or local body to do something new, or an Act authorising a class of contracts). It is construed so as to achieve the purpose for which the power was given, but only to the extent the words go. Enabling words are permissive in form, yet where the power is given for the benefit of others and the conditions for its exercise are met, there may be a duty to exercise it (Julius v. Lord Bishop of Oxford, House of Lords, 1880; Jogendra Singh, above).

4. Codifying statutes

A codifying statute states the whole of the law on a subject, both earlier statute and case law, in one Act. Indian examples are the Indian Contract Act, 1872, the Sale of Goods Act, 1930 and the Transfer of Property Act, 1882; the Bharatiya Nyaya Sanhita, 2023 now codifies substantive criminal law in place of the Indian Penal Code.

The rule comes from Lord Herschell in Bank of England v. Vagliano Brothers (House of Lords, 1891), on the Bills of Exchange Act, 1882: the proper course is to examine the language of the statute and ask what is its natural meaning, uninfluenced by considerations derived from the previous state of the law. Resort to the earlier law is permitted only where the provision is of doubtful import or uses words that had acquired a technical meaning. Otherwise the purpose of codification, a single accessible text, would be defeated.

5. Consolidating statutes

A consolidating statute brings together the provisions of several existing statutes on a subject, usually with minor amendments. The Labour Codes consolidate twenty-nine central labour laws. The presumption is that a pure consolidation does not change the law, so decisions on the earlier Acts remain good authority, and the earlier Acts may be looked at to resolve ambiguity. Where the Act “consolidates and amends”, that presumption is weaker. Sections 8 and 24 of the General Clauses Act carry forward references to, and orders under, the repealed Acts.

6. Statutes conferring rights

A statute that confers a right is construed so that the right is effective, not illusory. Where a statute creates a new right and also provides a special remedy or forum for it, that remedy must ordinarily be pursued and the civil court's jurisdiction is excluded: Premier Automobiles Ltd. v. Kamlekar Shantaram Wadke, 1975 INSC 180, (1976) 1 SCC 496, on rights created by the Industrial Disputes Act. Where the right exists at common law and the statute only adds a remedy, the old remedy survives.

7. Statutes conferring powers

How this is examined

The 10-mark question is on mandatory and directory provisions: definition, consequence, the factors, then Manbodhan Lal, Remington Rand, Raza Buland, Kailash and Jogendra Singh. The 6-mark notes are answered from sections 3 to 7: definition, example, rule, one authority. For codifying statutes, Vagliano is the case the examiner expects.
