The international director of the campaign organisation Cage has been convicted of a terrorist offence after refusing to hand over passwords to his mobile phone and laptop.
Muhammad Rabbani, 36, was found guilty at Westminster magistrates' court of wilfully obstructing police when he refused to cooperate at Heathrow airport last November. The test case could affect the way thousands of suspects stopped at UK airports and ports every year interact in the future with anti-terrorist officers.
Rabbani was given a conditional discharge for 12 months and ordered to pay £620 in costs. His lawyers plan to appeal to the high court on the grounds that existing police powers do not sufficiently protect privacy or legally privileged material.
