A repeal is the formal removal or reversal of a statute, regulation or other rule of law. It may be enacted by the legislature, ordered under a statutory power, or effected through procedures such as referendum or parliamentary motions. In legislative and procedural contexts the term is used broadly to describe the act of cancelling previously established legal requirements or policy measures. For discussion of the underlying legal instrument, see law, while parliamentary motions that seek to undo earlier decisions are part of parliamentary procedure and often involve the same assembly that adopted the original act, the assembly.

Types of repeal

  • Repeal with replacement: the old provision is removed and a new one takes its place, sometimes updating or consolidating policy.
  • Repeal without replacement: the law is removed and no direct substitute is enacted; regulatory duties or penalties lapse.
  • Partial versus total repeal: a statute may be partly repealed (certain sections removed) or wholly repealed (the entire enactment removed).
  • Express and implied repeal: express repeal is clearly stated in new legislation, while implied repeal occurs when a later law is inconsistent with an earlier one and the later provision governs.
  • Revocation of delegated instruments: removal of secondary rules (often called secondary legislation) is commonly termed revocation rather than repeal in jurisdictions such as the United Kingdom and Ireland.

How repeal is carried out

Primary repeal normally requires a statute enacted by the competent legislature. A repeal clause may be included within a new act to remove earlier laws explicitly, or a new enactment may implicitly override prior inconsistent provisions. Delegated or subordinate rules can often be revoked by the minister or agency given authority for that purpose. In some systems, direct democratic tools such as referendums or initiatives can mandate repeal or require the legislature to act. Administrative mechanisms for repeal or revocation vary according to the instrument being removed and the legal powers available to decision-makers.

  • Prospective effect: Most repeals operate from the date specified in the repealing measure and affect future rights and obligations.
  • Savings provisions: To protect ongoing matters—such as concluded proceedings, vested rights, or ongoing contracts—legislatures commonly include savings clauses. For example, modern statutory interpretation regimes adjust the old common law idea that repeal "obliterated" an earlier statute entirely; the common law rule in England and Wales has been moderated by statutory interpretation provisions and saving measures under later statutes such as the Interpretation Act.
  • Retrospectivity: A repeal rarely restores actions that were illegal under the repealed law unless the repeal expressly provides retrospective effect.
  • Constitutional limits: Constitutions may restrict what can be repealed (for instance, fundamental rights or entrenched provisions) and courts can review improperly enacted repeals for conformity with constitutional procedure.

History, practice and notable distinctions

Historically, under older common law practice a repeal was treated as removing the statute "from the record," but modern practice recognises the need to preserve legal certainty and saved consequences. Many jurisdictions distinguish between repeal, revocation, annulment and rescission: repeal commonly refers to legislative removal; revocation more often applies to subordinate instruments; annulment is typically a judicial declaration that a rule was invalid; and rescission may describe undoing of a decision in parliamentary procedure. Parliamentary bodies also use procedural motions to rescind or expunge actions taken earlier, and statute law revision programmes aim to identify obsolete enactments for formal repeal.

Importance and examples

Repeal is a central mechanism for legal reform: it removes outdated or harmful rules, allows policy change, and simplifies the statute book. Lawmakers may repeal tax provisions, criminal offences, or regulatory duties as policy evolves. Where a repeal is accompanied by re‑enactment, legislators can modernise language and clarify application; where it is not replaced, repeal can deregulate activity or eliminate anachronistic offences. For further reading on legislative texts and related procedural matters see parliamentary records and interpretation materials, and general resources on statutory reform at law and parliamentary procedure references such as procedural guides.

Relevant resources and practical guidance are available from government and legal publishers; for procedural details about how an assembly may rescind a prior decision consult authoritative manuals and the rules of the relevant assembly when planning or responding to repeal measures.
