Restrictions on the power of the authorities to arrest and detain individuals also emanate from article 2 paragraph 2 of the Basic Law which guarantees liberty and requires a statutory authorization for any deprivation of liberty. In addition, several other articles of the Basic Law have a bearing on the issue. The most important of these are article 19, which generally requires a statutory basis for any infringements of the fundamental rights guaranteed by the Basic Law while also guaranteeing judicial review; article 20, paragraph 3, which guarantees the rule of law; and article 3 which guarantees equality.
