In response to concerns that the principle of double jeopardy was no longer referred to in judgments of the Court of Appeal in references made by the Attorney General, the court expressed its view that, although the double jeopardy principle remained for consideration in the kind of case identified in Attorney General’s Reference (Nos 14 and 15 of 2006) [2006] EWCA Crim 1335, the practice had evolved so that no reference was made to it, save in the rare category of case in which it was likely to arise.
