In re Joseph Hill & Co, Solicitors [2013] EWCA Crim 775 ; [2013] WLR (D) 210
“There was a statutory obligation on the defence to give notice to the prosecution of the name, address and date of birth of any witness whom the defendant believed was able to give evidence in support of his alibi. If there was a practice of advising that the names and addresses of alibi witnesses should not be disclosed unless and until they had provided signed proofs of evidence, that practice was misguided and wrong.”
