Why It Matters

The decision delineates how far ministers can halt public inquiries, shaping transparency and accountability in investigations that affect public policy and trust.

Key Takeaways

  • Ministerial power to suspend inquiries is discretionary, not strictly necessary
  • Suspension duration must match minister's good‑faith estimate of required time
  • Consultation with chair and parliamentary reasons are mandatory procedural safeguards
  • Courts treat suspension decision as two distinct questions: yes/no and length
  • Statutory misinterpretation could render suspensions irrational and subject to challenge

Summary

The court heard a judicial review application (JR222) concerning the scope of ministerial discretion under section 131 of the Inquiries Act 2005. The central issue was whether the minister may suspend an inquiry merely because it is desirable, or must be satisfied that suspension is strictly necessary to allow another criminal or civil proceeding to conclude.

The parties argued that the statute grants a broad discretionary power, limited only by purpose and duration. The minister must assess in good faith how long the related investigation will take, and cannot suspend for longer than that estimate. Procedurally, the minister must consult the inquiry chair and provide reasons to the relevant legislature. The court highlighted that the decision splits into two questions – whether to suspend and, if so, for how long – contrary to the Court of Appeal’s earlier single‑question approach.

Key excerpts included the minister’s briefing that “the minister has a discretionary power … to suspend an inquiry where it is … necessary to allow for the completion of a criminal investigation,” and the discussion of a six‑week trial illustrating the good‑faith judgment test. The judgment also cited a recent parliamentary principle (EF 1 224 ¶ 41) affirming that statutes are enacted against the backdrop of established common‑law principles.

The ruling clarifies the legal boundaries of inquiry suspensions, signalling that ministers can act on strategic considerations but must anchor any suspension in a reasoned, time‑limited estimate. This interpretation will guide future inquiries, inform legislative drafting, and provide a benchmark for challenges against potentially irrational suspensions.
