Terrorism Bill

Does the hon. Gentleman accept that we are dealing not with ordinary questions of criminal jurisdiction, but terrorist activities that verge on being threats of war and could lead to public emergency, which is why the question of derogation arises? Does he also realise that there is a whole stack of case law on the matter, including the Lawless case in Eire in 1961, when an even longer time period than that contemplated was upheld?
