	At present, Speakers' Corner is concurrently regulated by the Parks and Trees Regulations (Cap. 216, Rg. 1, 2006 Rev. Ed.), the Public Entertainments and Meetings (Speakers' Corner) (Exemption) (No. 2) Order 2011 (S 493/2011) (issued under the PEMA) and the Public Order (Unrestricted Area) (No. 2) Order 2011 (S 494/2011) (issued under the ("POA")). The applicable conditions have remained essentially unchanged. Speakers and demonstration organizers must be Singapore citizens, while participants at demonstrations must be either citizens or permanent residents. Banners, films, flags, photographs, placards, posters, signs, writing or other visible representations or paraphernalia containing violent, lewd or obscene material must not be displayed or exhibited. Persons making speeches must use any of the four official languages of Singapore (English, Malay, Mandarin and Tamil) or related dialects, and organizers of demonstrations must be present throughout the event. Events must not deal with any matter that relates directly or indirectly to any religious belief or to religion generally, or which may cause feelings of enmity, hatred, ill-will or hostility between different racial or religious groups in Singapore. Events adhering to the regulations are not immune from other existing laws such as those relating to defamation and sedition.
