Although there is no constitutional guarantee of the right to freedom of peaceful assembly, it has been upheld by the judiciary as a fundamental right. The Police Ordinance (1971) and the Penal Law (1977) regulate the right to peaceful assembly, and they require prior permission to hold a demonstration or gathering involving more than 50 and where speeches or a march will be held in open air. In practice, government authorities reject permits for numerous public gatherings and repress them while they are being held. Gatherings which are anti-government, oppose government policies, or support Palestinian causes are specifically targeted.
