Maxims and Presumptions in Interpretation of Statutes

Updated 11 October 2026 · Fact-checked

Maxims are short Latin rules that help a court find the meaning of doubtful words in a statute. Presumptions are starting assumptions about what the legislature intended. To answer a question, name the maxim, state its condition, apply it to the words given, and conclude on the meaning.

Understand Maxims and Presumptions in Interpretation

A court first reads the words of a statute in their plain sense. When the words are unclear, or a general word sits beside specific ones, the court uses maxims. A maxim is a short, settled rule of reasoning, usually in Latin. It is an aid, not a law. It gives way if the statute shows a different intention.

Ejusdem generis means 'of the same kind'. When specific words of one class are followed by general words, the general words are read as limited to things of that same class. Example: 'cars, buses, trucks and other vehicles' would cover similar motor vehicles, not an aeroplane. It usually needs a list of two or more specific words that form a class, followed by a general word. It does not apply where the specific words show no common class, or where the statute shows a wider intention.

Noscitur a sociis means 'a word is known by the company it keeps'. An unclear word takes colour from the words around it. If 'tea, coffee, sugar and spices' are listed, 'spices' means edible items, not a chemical. The difference: ejusdem generis deals with a general word after specific words, while noscitur a sociis can help with any doubtful word in a group. Ejusdem generis is a narrower application of the wider idea in noscitur a sociis.

Expressio unius est exclusio alterius means that mentioning one thing excludes others. If a section lists certain items and nothing more, the court may infer that unlisted items are left out. Generalia specialibus non derogant means a general provision does not override a special one. If a special law covers the matter, the general law does not cut it down. Other maxims you may meet: ut res magis valeat quam pereat (a statute should be read so that it works, not fails) and delegatus non potest delegare (a delegate cannot sub-delegate, unless allowed).

Presumptions are starting assumptions a court makes. Common ones: a statute is presumed to be constitutional and valid; it is presumed not to be retrospective unless it clearly says so (this is especially so for laws that take away rights or create new liabilities); it is presumed not to take away a person's rights or the jurisdiction of courts without clear words; and it is presumed that the legislature does not use words without purpose. These can be rebutted by clear words or necessary implication. Related rules are in the General Clauses Act, 1897, for example Section 6 on the effect of repeal and Section 27 on service by post.

Key rules to remember

Ejusdem generis: Specific words of a class + general word → general word limited to the same class; Needs a class formed by the specific words. Does not apply if a different intention appears or no class exists.
Noscitur a sociis: Meaning of a doubtful word = drawn from the words associated with it; Use for any unclear word in a group of related words.
Expressio unius est exclusio alterius: Express mention of one thing → exclusion of others; A guide to intention, not an absolute rule. Do not use it where the context shows the list is only illustrative.
Generalia specialibus non derogant: General provision does not override a special provision on the same subject; The special law prevails in its own field.
Presumption against retrospectivity: Statute operates prospectively unless it clearly says or necessarily implies otherwise; Stronger for provisions that impose new burdens or take away vested rights.
General Clauses Act, 1897, Section 6: Unless a different intention appears, repeal does not affect rights, liabilities, penalties or proceedings already acquired, incurred or begun; Also does not revive anything not in force at the time of repeal.
General Clauses Act, 1897, Section 27: Service by post = properly addressing, pre-paying and posting by registered post; deemed effected when the letter would be delivered in the ordinary course of post, unless the contrary is proved; Applies unless a different intention appears.

How to solve Maxims and Presumptions in Interpretation questions

Use this method for any question that asks you to explain a maxim, compare maxims, or apply one to given words.

1Read the question and mark the words that are in doubt, and any list around them.
2Identify the maxim that fits: a list of specific words plus a general word points to ejusdem generis; a single unclear word in a group points to noscitur a sociis; a closed list points to expressio unius; a clash of general and special provisions points to generalia specialibus.
3State the meaning of the maxim in one line, with its Latin name spelt correctly.
4State the conditions for its use, such as the need for a class of two or more specific words.
5Apply it to the facts: say what the class is, and whether the disputed item falls inside it.
6Note any reason the maxim may not apply, such as a contrary intention in the statute.
7Conclude clearly with the meaning the court would adopt.
8If a presumption is involved, state it and say whether any clear words rebut it.

Quickest way: Three-line maxim answer

When to use it: Use when time is short, for short-note or two-to-four mark parts.

Line 1: Name and translate the maxim, and define it in one sentence.
Line 2: Give one clear example with a list and a doubtful word, and say how it is read.
Line 3: State the limit, that it applies only where no contrary intention appears, and give the conclusion.

Common mistakes in Maxims and Presumptions in Interpretation

Treating ejusdem generis and noscitur a sociis as the same rule.
Both read words in light of their neighbours, so they look alike.
Fix: Say ejusdem generis needs specific words followed by a general word, and limits that general word to the same class. Noscitur a sociis explains any unclear word from its associated words.
Applying ejusdem generis to a single specific word.
Students forget that a class must first be formed.
Fix: Check for at least two specific words that show a common kind before you apply it.
Treating maxims as binding laws.
Latin phrasing sounds like a hard rule.
Fix: Write that maxims are aids to find intention and yield to a contrary intention in the statute.
Applying expressio unius to every list.
Students read it as 'always exclude the rest'.
Fix: Say it is a guide only. If the list is clearly illustrative, the inference of exclusion does not follow.
Reversing generalia specialibus, saying the general law prevails.
The Latin words are easy to confuse.
Fix: Remember: general provisions do not derogate from special ones. The special law governs its own field.
Stating Section 6 or Section 27 of the General Clauses Act, 1897 without its 'unless a different intention appears' condition.
Students memorise the effect and skip the opening words.
Fix: Always include that condition. For Section 27, add the words 'unless the contrary is proved' on the time of service.

Worked examples

Example 1

A statute penalises a person who 'keeps a house, office, room or other place for betting'. X runs a betting operation from an open street corner. Using a suitable maxim, decide whether X is covered.

Show the solution

The doubtful words are 'other place'. They follow the specific words 'house, office, room'.
This is a list of specific words followed by a general word, so ejusdem generis applies.
The specific words describe enclosed premises. They form a class of enclosed places.
'Other place' is therefore limited to places of the same kind, that is, enclosed premises like a house or room.
An open street corner is not an enclosed place of that kind.
Check for contrary intention: none appears in the text given.

Answer: On the ejusdem generis reading, 'other place' means a place like a house, office or room. An open street corner falls outside that class, so X is not covered by this provision, unless the statute shows a wider intention.

Example 2

Distinguish between ejusdem generis and noscitur a sociis, with an example of each.

Show the solution

Define ejusdem generis: where specific words of a class are followed by general words, the general words are limited to that class.
Example: 'cattle, sheep, goats or other animals' is read as farm animals, not wild animals.
Define noscitur a sociis: a doubtful word is understood from the words that keep company with it.
Example: in 'tea, coffee, sugar and spices', 'spices' means edible items.
Compare: the first needs a closed list of specific words followed by a general term; the second can be used for any unclear word in a group.
Add: both are aids and yield to a contrary intention.

Answer: Ejusdem generis limits a general word following specific words to the same class. Noscitur a sociis gives a doubtful word its meaning from its associated words. The first is narrower and works only with a class plus a general word. The second is wider in its use.

Exam tips

Write the Latin name correctly and give its English meaning in the first line. It earns easy marks.
Always add one short example. Examiners look for it in short notes.
In application questions, name the class before you decide whether the item falls in it.
Close with the limit: maxims apply only if no contrary intention appears.
When citing the General Clauses Act, 1897, give the section only if you are sure, and include its 'unless a different intention appears' condition.

Maxims and Presumptions in Interpretation: frequently asked questions

What is the difference between ejusdem generis and noscitur a sociis?

Ejusdem generis limits a general word that follows a list of specific words to the same class. Noscitur a sociis explains any doubtful word from the words around it. The first is a narrower rule.

What does expressio unius est exclusio alterius mean?

It means that the express mention of one thing excludes others. If a statute lists certain items, the court may infer that unlisted items are left out. It is only a guide and does not apply where the list is clearly illustrative.

Are maxims of interpretation binding on courts?

No. They are aids to find the intention of the legislature. A court will not use a maxim if the statute shows a different intention.

Is a statute presumed to be retrospective?

No. The general presumption is that a statute operates prospectively unless it clearly says or necessarily implies otherwise. The presumption is stronger where the statute takes away vested rights or creates new liabilities.
