"In law consent given when disinhibited by drink, even if consent would not have been given when sober, is nevertheless consent."
"the circumstances which the jury are to take into account in determining whether the accused could reasonably have been expected to mention the fact in question will include what it knows about the length of the questioning, and the relative significance or importance of the fact in question to the matters about which the accused is being interviewed; and its relative significance or importance to any answers he does give in interview or to the contents of any prepared statement which he has given"
"The jury must consider all the circumstances, including the degree of relevance or importance of the unmentioned fact to the account relied on at trial. In doing so the jury may properly take account of the length of the interviews and the background to them, and what can be inferred therefrom about the nature of the questioning and what the accused could reasonably have been expected to volunteer as part of his account of events."
"Secondly, there is no requirement that the unmentioned fact must be one about which the accused has specifically been asked a question. The language of the statute does not impose such a requirement and the test is simply whether in the face of the questioning the fact is one which the defendant could reasonably have been expected to mention."
