Freedom of religion is guaranteed by the Uganda Constitution, but religions are expected to be registered with the government. Some religions considered to be cults are restricted. The Catholic Church, the Church of Uganda, the Eastern Orthodox Church in Uganda, and the Uganda Muslim Supreme Council are registered under the Trustees Incorporation Act. Most other religious groups are registered yearly as non-governmental organizations.
