Under the previous draft of the UK bill, yes -- see http://www.stand.org.uk/
for an amusing demonstration of this point. But the new draft says that you
can only be compelled to hand over a key the authorities suspect you "have or
have had." Still puts a horrendous burden of proof on you to show you don't
currently possess it, unless you use PFS all the time.
