Cases considering section 67 58
[2026] EWCA Crim 570 · 22 April 2026
Section 67 defined the appellate threshold: the ruling could be reversed only if it was wrong in law, involved an error of law or principle, or was not a reasonable ruling for the judge to make. The Court applied that standard and dismissed the appeal. (see para [26])

The court treated the statutory grounds—wrong in law, error of law or principle, or an unreasonable ruling—as a high hurdle for the prosecution. It held that the Crown Court ruling met the threshold for reversal. (see paras [2]; [30])
[2025] EWCA Crim 1442 · 12 November 2025
