within a reasonable time, and the Prime Minister has discretion to determine when it should be held. The law provides that a by-election need only be called in a GRC if all the MPs in the constituency vacate their seats. It has been argued that the law should be amended, otherwise electors living in a GRC where a vacancy has arisen will lack parliamentary representation, and with a missing MP the remaining MPs may find it difficult to deal with constituency matters. Also, if the MP who vacates their seat is from a minority community and the seat is not filled, this would defeat the purpose of the GRC scheme which is to ensure a minimum level of minority representation in Parliament. In response, the Government has said that the other MPs of the GRC continue to represent the electors and should be able to handle constituency matters without any problems. Moreover, the loss of one minority MP in a GRC should not make much difference in practice as there will be other minority MPs in Parliament. NCMPs are only declared to be elected at general elections, and there is no provision for the seat of an NCMP to be filled if it falls vacant. On the other hand, if an NMP vacates their seat, a Special Select Committee of Parliament may nominate a replacement to be appointed by the President.
