Manjit Singh Gill QC successfully represented ‘JJ’ in ‘JJ’ and others v Secretary of State in which the House of Lords held that an 18 hour form of house arrest under a control order was an unlawful deprivation of liberty contrary to art 5 of the ECHR. The House also gave important rulings in linked appeals on other aspects of the control order regime. This is the first case to reach the House of Lords on the Prevention of Terrorism Act 2005 which was passed after the House of Lords held, in A, X, Y and others v Secretary of State [2004] (the ‘Belmarsh’ case) in Mr Manjit S. Gill QC also represented X and Y, that indefinite detention of suspected terrorists was incompatible with art 5 of the ECHR.
