It is quite alot to do with the Right to Silence, the European Human Rights act clearly states that you have the right to silence and evidence obtained under duress cannot be used in a court against you, pretty basic safe guards of our legal rights really. Unfortunately the Road Traffic Act 1988 section 172 (how sad am I) requires the registered keeper of the vehicle to identify the driver at the time of an alleged offence (normally that alleged offence is passing a speed camera above the speed limit) or face prosecution for not identifying the driver. The threat of prosecution is enough to mean that the information is obtained under duress, hence the reason why it was challenged a few years ago and why the Privy council ended up making a decision.AFAIK, nowt to do with the 'right to silence' thing - there's a provision in the RTA 1988 stating its an offence NOT to say who was driving at the material time, that was held not to be a breach of the protection against self incrimination following ratification of the ECHR in the Human Rights Act 1998.
As Shug mentioned, too much time on pepipoo.com as a result of an NIP that came through my door, I learnt alot, got my case and a colleagues dropped and made a few useful contacts, one such contact has his Right to Silence case at the ECHR at the moment, he is being assisted legally by Liberty, should get the verdict by the end of March, these wheels turn very slowly. It really does take a lot of time, some thought, and occasionally a bit of bottle to fight these cases, but it's worth it when you get the little "No Further Action" letter.lol. I concede to someone obviously far more knowledgable on the subject!!
