Presumption Against Intending Injustice — Interpretation of Statutes Notes

Presumption Against Intending Injustice

Judges begin from a charitable assumption about the legislature: that it did not mean to be unjust. So where a statute is capable of two readings — one just, one harsh — the court leans to the just one. As Viscount Simon put it in Nokes v Doncaster (1940), if the words permit, the court prefers the construction that avoids injustice and absurdity. It is a supporting presumption, the companion of the golden rule.

What is the presumption against injustice?

The presumption is that the legislature does not intend to cause injustice, hardship or an unjust result, and where the words are capable of two constructions, the court prefers the one that avoids injustice.

Its features:

1. A tie-breaker on ambiguity. The presumption operates only where the words are genuinely open to two meanings. It does not let the court override plain words merely because the result is harsh — if the language is clear, the court must apply it (the literal rule), however unjust.

2. Companion of the golden rule. It works with the golden rule (Unit III) and the presumption against absurdity (Topic 8): a reading that produces manifest injustice or hardship is treated as one the legislature is unlikely to have intended, and is avoided where the words permit.

3. Injustice to individuals and the public. The presumption guards against results that would be unjust to individuals (e.g. penalising the innocent, taking away vested rights) or contrary to the public interest, unless the legislature has clearly commanded it.

4. Rebuttable. Like all these presumptions, it is rebuttable: clear and express words showing the legislature did intend the harsh result must be given effect. The court’s task is to find intention, not to substitute its own sense of fairness.

Principle (Nokes v Doncaster Amalgamated Collieries, 1940): “If the choice is between two interpretations, the narrower of which would fail to achieve the manifest purpose of the legislation, we should avoid a construction which would … produce injustice or absurdity, and prefer that which avoids such a result, provided the words admit of it.”

In Simple Terms: Courts assume the legislature did not mean to be unjust, so where words can be read two ways, they choose the reading that avoids injustice or hardship. But this only works on genuinely ambiguous words — clear words that plainly command a harsh result must still be applied.

🧩 WORKED EXAMPLE — Choosing the just reading

Facts. A provision is capable of two readings: one would penalise a person for something entirely outside his control; the other would confine the penalty to his own default. The words fairly bear both.

Rule. Where a statute admits of two constructions, the court prefers the one that avoids injustice or hardship (Nokes v Doncaster (1940)).

Apply. Penalising a person for a matter outside his control would be unjust and is unlikely to have been intended; the words also bear the reading that confines the penalty to his own default.

Conclusion. The court adopts the reading that confines the penalty to the person’s own default, avoiding injustice — a choice open to it precisely because the words are ambiguous.

Case Laws

• Nokes v Doncaster Amalgamated Collieries (1940) — a construction that produces injustice or absurdity is avoided where the words admit of a better one.
• Tirath Singh v Bachittar Singh (1955) — a construction leading to an unjust or absurd result is not to be adopted if the words permit another.
