Subsidiary Rules (Same/Different Words; Exact vs Loose; Technical Words) — Interpretation of Statutes Notes

Subsidiary Rules (Same/Different Words; Exact vs Loose; Technical Words)

A drafter’s word-choices are not accidents. If she uses the same word twice, she usually means the same thing; if she switches to a different word, she usually means something different; and if she uses a technical word, she means it in its technical sense. These small, sensible presumptions — the subsidiary rules — help a court read a statute the way a careful drafter wrote it.

What are the subsidiary rules?

These are a cluster of presumptions about word-usage that support the primary rules. Each is a guide, rebuttable by context:

1. Same word, same meaning. A word used more than once in the same statute is presumed to bear the same meaning throughout — the legislature is presumed to be consistent. So a term defined or settled in one section carries that sense elsewhere in the Act, unless the context requires otherwise.

2. Different words, different meanings. Conversely, where the legislature uses different words, it is presumed to intend different meanings — a deliberate change of language signals a change of sense. If an Act uses “sell” in one place and “transfer” in another, they are presumed not to be identical.

3. Exact meaning preferred to loose meaning. Where a word has both a precise (exact) sense and a looser popular sense, the court prefers the exact meaning where the context calls for precision — the legislature is presumed to use words accurately, especially in a carefully drafted provision.

4. Technical words in their technical sense. Words that have a special technical or legal meaning (in law, science, trade or a particular art) are given that technical meaning, not their ordinary lay meaning, where the statute deals with that technical subject. “Negligence”, “possession”, “mortgage” carry their settled legal senses; a scientific term carries its scientific sense in a scientific statute.

5. Conjunctive and disjunctive — “and” / “or”. Ordinarily “and” is conjunctive (both/all) and “or” is disjunctive (either/one). But the court may read “or” as “and” (and vice versa) where the context or the evident intention so requires, to avoid an absurd or unintended result.

6. Mandatory presumptions of consistency and effect. Alongside these sit the general presumptions that every word is given effect and that a construction avoiding surplusage and absurdity is preferred (Topic 6).

Each of these is a presumption, not an absolute rule — the context can rebut any of them. They are tools to read the statute as a careful drafter intended.

Principle (same word, same meaning — Bhogilal Chunilal Pandya, 1959): “There is a presumption that the same word is used in the same sense throughout a statute, and different words are used to convey different meanings, unless the context indicates the contrary.”

In Simple Terms: These are common-sense presumptions about a drafter’s words: the same word means the same thing, different words mean different things, an exact meaning is preferred to a loose one, and technical words carry their technical sense. “And”/“or” usually mean both/either, but can be swapped to avoid absurdity. Each presumption yields to a clear context.

🧩 WORKED EXAMPLE — “or” read as “and” to avoid absurdity

Facts. A statute lets the Government appoint special judges “for any area as for any case or group of cases”. The Government appoints, in one order, judges for an area, a case, and a group together. A party argues “or” is strictly disjunctive, so the combined order is void.

Rule. “Or” is ordinarily disjunctive, but may be read conjunctively where the context and evident intention require, to avoid an absurd or unintended result.

Apply. Reading “or” strictly to forbid a combined appointment would defeat the object of enabling flexible appointment of special judges; the sensible reading allows appointment for an area, a case, and a group as the need arises.

Conclusion. “Or” is read to permit the combined order; it is not fatal. The strict-disjunctive reading is the decoy — the subsidiary rules allow “or” to bend to the evident intention.

Case Laws

• Bhogilal Chunilal Pandya v State of Bombay (1959) — presumption that the same word bears the same meaning throughout a statute, unless the context indicates otherwise.
• State of Bombay v Hospital Mazdoor Sabha (1960) — technical and defined words are read in their proper sense within the statutory context.
• Ishwar Singh Bindra v State of U.P. (1968) — “or” may be read as “and” (and vice versa) where the context and intention require.
