Any reason for this not being at Regulation of Investigatory Powers? Were there two? Martin [22:24, 20 May 2003 (UTC)]
- Not that I'm aware of; any objections to moving it? — Matt 07:11, 4 Sep 2004 (UTC)
Burden of proof
"The accused must prove that they do not have the key, claiming to have mislaid or forgotten it might not be accepted as a defence." What if the accused claims never to have possessed the key? The article is not clear on this point; the text of the Act seems to imply that a prosecutor needs to prove that the accused possessed the key at some time, but it isn't entirely clear and various popular accounts suggest the opposite.
- AIUI, which is mainly a result of having talked about the Act with people who have read it and understand it far better than I ever will, the burden of proof would, rather inexplicably, rest on the defence, not the prosecution, in showing that the defendent had at no time had the said key. Lovely, isn't it? Maybe someone more knowledgable could comment, and correct/update?

- This seems to be the case, but I don't know much about this. This site (http://www.cs.man.ac.uk/~chl/scenarios.html) analyses a variety of scenarios, and number 14 touches on this, suggesting that Bob sending Alice a message using her public key is sufficient grounds to believe that Alice once owned a corresponding private key, "Alice had had the key"...— Matt 04:46, 3 Sep 2004 (UTC)
- Number 14 relates to the reverse onus regarding continued possession, in a case where past possession is presumably an undisputed fact; "That Alice had had the key ... which indeed she had" is specifically listed as one of the things that the prosecution has to show. This example does not directly address the question of the onus of proof regarding whether the defendant ever possessed the key; I don't even see how one can read into it any inference from circumstantial evidence, as you are apparently doing.
