Parliamentary Conventions

Parliamentary conventions are established practices that political actors generally treat as obligatory, although they are not usually enforceable as law. They supplement the Constitution and formal rules by guiding conduct where written provisions leave choices, discretion or procedural gaps. Their authority rests on acceptance, precedent and political accountability.

Relationship with written procedure

Under Article 118, each House may make rules for regulating its procedure and conduct of business. Conventions operate alongside these rules: they interpret broad powers, structure discretionary choices and promote predictable conduct, but cannot override the Constitution, statutes or valid rules.

How conventions facilitate Parliament

Conventions make adversarial politics compatible with orderly deliberation and accountability.

• The expectation that the Speaker acts impartially strengthens confidence in rulings on debate, discipline and procedure.
• Consultation among the government, opposition and floor leaders helps allocate time, sequence business and reduce avoidable conflict.
• The convention, followed since 1967, of appointing an opposition member as Chairperson of the Public Accounts Committee strengthens non-partisan scrutiny of public expenditure.
• Norms of reasoned debate, ministerial explanation and accommodation of minority viewpoints help translate formal collective responsibility into everyday parliamentary accountability.

Enforcement and limitations

A convention is ordinarily not judicially enforceable by itself. Its breach instead attracts parliamentary criticism, political pressure, reputational loss or electoral accountability. Because observance depends on mutual restraint, weakened conventions can produce procedural confrontation, reduced scrutiny and excessive reliance on numerical majority.
