 The Landau Commission resulted in hundreds of petitions by detained Palestinians complaining that force had been used against them during ISA interrogations.In isolated cases, interim orders were issued temporarily prohibiting the ISA from using all or some of the methods, but in September 1999 the High Court refused to rule whether they are legal under Israeli and international law.In 1991, Israel ratified the UN International Covenant on Civil and Political Rights of 1966, a measure which states (Article 7) "no one shall be subjected to torture, inhuman or degrading treatment or punishment".
