The government prohibits any publications that it feels will incite racial or religious disharmony, and has asked that religious matters not be discussed in public due to their sensitivity. It claims nobody has been arrested under the Internal Security Act for religious reasons. The government may demolish unregistered religious places of worship, and nongovernmental organisations have complained about the demolition of unregistered Hindu temples. These were often constructed on privately owned plantations prior to independence in 1957. After independence plantations became government property. In 2006 the state of Negeri Sembilan announced the demolition of a Hindu temple, although the temple sought injunction and took it to court. State governments control mosques, appoint imams, and provide guidance for sermon content. The conflict between the federal and state governments over religious authority led to a slow pace of reform and development of laws relating to Islam. Other religious groups, such as the Malaysian Consultative Council of Buddhism, Christianity, Hinduism, Sikhism and Taoism (MCCBCHST), have supported political rallies.
