Severability Clauses in Adelaide Local Laws

General Governance and Administration South Australia 3 Minutes Read · published February 11, 2026

Severability clauses determine what happens if part of a local law or bylaw is found invalid. In Adelaide, South Australia, councils rely on severability wording to keep functioning provisions in force and to limit legal disruption to city rules. This guide explains how severability operates in the context of Adelaide local laws, who enforces bylaws, typical enforcement outcomes, and the routes to seek a variation, review or appeal.

What is a severability clause?

A severability clause states that if one provision of a local law is declared invalid by a court, the remaining provisions continue to apply. Councils include these clauses to preserve regulatory effect and to reduce the risk that an entire bylaw is struck down because of one invalid clause.

How severability is used in Adelaide local laws

Adelaide’s bylaw instruments commonly include severability or saving clauses in the enacting text or the schedule of provisions. Whether a clause protects the whole instrument depends on its wording and on judicial interpretation of severability under South Australian law. For statutory detail affecting councils, see the Local Government Act and the City of Adelaide bylaw materials. City of Adelaide - By-laws^[1] Local Government Act 1999 (SA)^[2]

A clear severability clause helps councils and courts isolate and preserve valid regulatory provisions.
