The Court of Appeal yesterday dismissed appeals filed by four organisations which sought a declaration that the existence and establishment of vernacular schools and the use of Mandarin and Tamil languages in such schools are unconstitutional. The four organisations are the Islamic Education Development Council (Mappim), Confederation of Malaysian Writers Association (Gapena), Ikatan Muslimin Malaysia (Isma) and Ikatan Guru-Guru Muslim Malaysia (I-Guru). The decision was delivered by a three-man panel comprising justices Datuk Supang Lian, Datuk M. Gunalan and Datuk Azizul Azmi Adnan, Bernama reported. The Court of Appeal has ruled against a challenge to the existence of vernacular schools. AMIRUL SYAFIQ THESUN
