Criminal Cases Review Commission

StatusStableReviewdue UpdatedStands on2 sourcesSupportsnotes

The Criminal Cases Review Commission (CCRC) is the independent statutory body that investigates alleged miscarriages of justice in England, Wales, and Northern Ireland and refers cases back to the appeal courts when it finds a “real possibility” that the conviction or sentence would not be upheld. It was established by the Criminal Appeal Act 1995 in the wake of the Guildford Four and Birmingham Six and began work in 1997 — the first institution of its kind and the model for Gjenopptakelseskommisjonen, the Scottish SCCRC (1999), New Zealand’s commission (2020), and Canada’s (legislated 2024).

Record and structural limits

The CCRC receives about 1,400-1,600 applications a year. Its long-term referral rate is about 3 percent, and it fell to 0.8 percent in 2016/17 — a decline one solicitor described to the government’s 2018 tailored review as “quickly moving towards the point of vanishing.” Between 64 and 79 percent of referred appeals succeed, which means the gate is calibrated to pass only near-certainties.12

Two structural limits matter comparatively:

  1. The new-evidence requirement. A 2026 University of Exeter study of more than 400 CCRC case evaluations found that convictions resting on the weakest original trial evidence are the hardest to refer, because no “new” evidence exists to find; Andrew Malkinson’s seventeen-year wrongful imprisonment is the study’s emblematic case.3
  2. No capacity for systemic error. In the Post Office Horizon scandal — more than 900 prosecutions on defective accounting software, the largest series of wrongful convictions in British legal history — the CCRC referred 77 cases over four years, and the remaining convictions had to be quashed by an Act of Parliament in May 2024, after the Horizon Compensation Advisory Board concluded that case-by-case machinery could not process a systemic miscarriage.45

Significance for the wiki

The CCRC demonstrates that an independent investigative commission is a better gate than court-internal review but not a window into ground truth: its referral statistics measure its threshold, its denied set marks where that threshold sits, and its largest case overwhelmed it structurally. It is the comparison anchor for Hidden miscarriage risk and correction-channel opacity across democracies against both Sweden’s court-internal resning and Norway’s commission.
