Rule of Reasonable / Logical Construction

# Rule of Reasonable (Logical) Construction

When the literal rule produces a result that defeats the intention of the legislature, the court may resort to the Rule of Reasonable Construction.

## Core Principle

> Where the words of a statute appear prima facie clear and unambiguous but, on close scrutiny, turn out to be deficient in carrying out the legislature's intention, reasonable construction must be adopted.

If the ordinary meaning contradicts the apparent purpose of the Act, the court may modify the meaning of the words and even the structure of the sentence.

## Three Pillars of Reasonable Construction

### 1. Narrow interpretation should not defeat the purpose

If a strict literal reading would frustrate the statute's purpose, the court may go beyond the literal words.

### 2. Effect must be given to the intention of the legislature

The court has to look at:

  • Circumstances prevailing when the statute was passed,
  • The need that necessitated its passing.

### 3. Sensible meaning

Words must be construed to give a rational, fair and sensible meaning.

  • Default: ordinary and natural meaning.
  • If words are ambiguous: discover legislative intent.

## Governing Maxim

'Ut Res Magis Valeat Quam Pereat''It is better for a thing to have effect than to be made void.' When interpreting a statute, it should be done in a meaningful and sensible manner so that the statute is effective rather than rendered nugatory.

Worked example

### Example 1

R v. Allen: The defendant was charged with bigamy under Section 57 of the Offences Against the Person Act, 1861, which said 'whosoever being married shall marry any other person during the lifetime of the former husband or wife is guilty of an offence.' A literal reading would make the offence impossible — civil law does not recognise a second marriage, so no one could 'marry' twice. Held: Applying reasonable construction, the word 'marry' meant 'to go through a marriage ceremony.' The conviction was upheld.

⚠️ Common exam mistakes

  • Jumping to reasonable construction without first attempting the literal rule.
  • Confusing reasonable construction with rewriting the statute — courts modify only meaning/structure where necessary, they don't legislate.
  • Forgetting the maxim 'Ut Res Magis Valeat Quam Pereat', which is the foundation of this rule.
  • Believing reasonable construction can be used to defeat the clear intention of the legislature — it is meant to give EFFECT to that intention.
