If it's been 2 years, can they even prove that he can still remember the password? He hasn't had to use it for over 2 years, it would be entirely probable his memory of it has faded.

How about this theoretical situation: I place an encrypted file in a hard drive belonging to someone I dislike, and then frame them circumstantially with the likely possession of contraband data on said hard drive. Since he owns the device, he may be so unlucky as to have the authorities believe he knows how to decrypt the file despite him claiming he has no knowledge of how the file came to be or how to decrypt it. If they will not accept that argument, this seems like a good way to place a political opponent in jail indefinitely by someone with the means to craft such a scenario
