This joint decree, based on Law No. 1 of 1965 on Prevention of Abuse and/or Defamation of Religion, warns and orders adherents, members, and/or organisational members of Jemaat Ahmadiyah Indonesia, to cease the dissemination of their religious interpretations and activities that 'deviate' from the fundamental tenets of Islam. Failure to abide by the decree may result in disturbing the peace and social order and can, therefore, result in sanctions.
