I'm talking about the specific law that was being discussed, and the particular other law I used as an example. And the protection mentioned was the one of double jeopardy which had also been explicitly mentioned.
Double jeopardy was partially eliminated in the UK in 2003 for qualifying offenses. I don’t think this has been tested, but during a retrial, a refusal to provide a password would be a separate RIPA offense from any refusal during the first trial. So you could actually be jailed more than once for this. For qualifying offenses all that is required for a retrial is “new and compelling evidence” which is a low hurdle for politically unpopular defendants.
