Procedural Posture

Judicial Review Application Challenging Prime Minister's Advice to Prorogue Parliament / Intervention Motions Decided; Hearing Scheduled (expedited) for Feb 13 14, 2025

  1. 1 Whether the Prime Minister's advice to the Governor General to prorogue Parliament is justiciable
  2. 2 Whether constitutional conventions governing prorogation are judicially enforceable
  3. 3 Whether Canadian courts should follow or distinguish R (Miller) v The Prime Minister ([2019] UKSC 41)

Ratio Decidendi

The court granted leave to intervene for Democracy Watch, the Canadian Constitutional Law Initiative, and the BCCLA because each demonstrated usefulness to the court on novel constitutional questions, a genuine institutional interest, and that admission served the interests of justice; the court dismissed other intervention requests where applicants lacked a demonstrable genuine interest, sought to introduce new issues or evidence, or failed to comply with procedural rules, and refused to relax Rule 109 via Rule 55 to allow materials from a non-genuine-interested party.
