The British brought the system of administrative detention to Palestine when they were the mandatory power. The rules also authorised military courts, restriction of movement, censorship, the expropriation and demolition of houses, arbitrary searches and curfews, and were used by the British against both Palestinians and immigrants of Jewish and other religious backgrounds. Despite many of its founders being caught on the wrong side of these laws, Israel adopted them in 1948 and has strenuously resisted attempts to modify their provisions.
