The decision to block the extradition of Gary McKinnon is set to pave the way for a ‘forum bar’ which would give judges the power to bar prosecution overseas if they believe it is in the interests of justice.

During yesterday’s (16 October) announcement of the decision in the high-profile McKinnon case, Home Secretary Theresa May confirmed plans to introduce the forum bar, which would mean – in cases where prosecution is possible in both the UK and another state – UK citizens could present their defences in the UK rather than facing extradition.
