issue. The referral was to examine the constitutional validity of quotas based on religion. Kerala Public Service Commission has a quota of 12% for Muslims. Religious minority (Muslim or Christian) educational institutes also have 50% reservation for Muslim or Christian religions. The Central government has listed a number of Muslim communities as backward Muslims, making them eligible for reservation. Criticism, controversies and protests The Union Government on 22 December 2011 announced the establishment of a sub-quota of 4.5% for religious minorities within the existing 27% reservation for Other Backward Classes. The reasoning given was that Muslim communities that have been granted OBC status are unable to compete with Hindu OBC communities. It was alleged that the decision was announced as the Election Commission announced Assembly elections in five states on 24 December 2011. The government would not have been able to announce this due to the model code of conduct. On 12 January 2012, the Election Commission stayed implementation of this decision for violation of the model code of conduct. Later, Justice Sachar, head of the Sachar Committee that was commissioned to prepare a report on the latest social, economic and educational condition of the Muslim community of India, criticised the government decision, saying "Such promises will not help the backward section of minorities. It is like befooling them. These people are making tall claims just to win elections". He suggested that instead of promising to give reservations, the government should focus on basic issues of improving administration and governance. On 28 May 2012, the Andhra Pradesh High Court quashed the sub-quota. The court said that the sub-quota has been carved out only on religious lines and not on any other intelligible basis. The court criticized the decision: "In fact, we must express our anguish at the rather casual manner in which the entire issue has been taken up by the central government.".
