“It is unlawful for a public authority to act in a way which is incompatible with a Convention right”
"The terms used to formulate the law by the judges of the Court of Appeal (which include myself in Wehner's case) have not been happy. They have spoken of orders being void or null for lack of jurisdiction in the court to make them. But you cannot describe as a nullity an order made by a superior court of record, which is what the Crown Court is:section 4(1) of the Courts Act 1971 . Nor is the question really one of jurisdiction: it is a question whether the court has exceeded its power. An order of the Crown Court, once made, may be in excess of its statutory power or otherwise irregular. But it is not a nullity. And it would undermine the authority of the criminal law if orders made by the highest court of trial in criminal matters could be disregarded as nullities. The order of the Crown Court stands unless and until set aside by the court itself upon application or, if appeal lies, by the appellate tribunal to which the appeal is taken." 30. This reasoning was applied in R v Reynolds and ors[2008] 1 WLR 1075 in which the Crown Court had passed an extended sentence when the legislation mandated a (more severe) sentence of imprisonment for public protection. Being unable to increase the sentence, Latham LJ put the matter in this way (at para.23): "
"The question for decision is whether the claimants were 'sentenced' under the dangerous offender provisions in the 2003 Act when the amendments were brought into force. The short answer is that they were. They continued in force and governed the detention of the appellants until the moment when they were substituted by the sentence ordered in the Court of Appeal. The appeals against sentence, although successful on the grounds that the sentence was excessive, did not nullify the sentences imposed in the Crown Court. They simply replaced them. Accordingly the provisions in the 2008 Act were 'of no effect' in the relation to them." 32. In the light of this analysis, I have no doubt that the appellant remained subject to imprisonment for public protection until the Court of Appeal allowed his appeal and reduced the sentence to the determinate term. Furthermore, the other domestic authorities cited in support of the proposition that a quashed sentence is unlawful and rendered of no effect do not support the contrary proposition. … 35. Benham also makes it clear that detention following sentence by a magistrates' court is capable of being unlawful although error will not necessarily retrospectively affect the lawfulness of detention. Thus, although detention following an order which has no foundation in law because of a failure to observe a statutory condition precedent is in excess of jurisdiction, acts of a magistrates' court which were within its jurisdiction were valid and effective unless or until they were overturned by a superior court: see para. 43. This decision is not inconsistent with the decision in Cain and, for the reasons set out above, does not assist the appellant. 36. More on point is Krzycki v Germany [1978] 13 DR 57 in which the Commission was concerned with compensation for preventative detention after a successful appeal against revocation of provisional release from detention. Although factually different from the present case, the principles were expressed in these terms (at page 11): "
