In Singapore, there are two types of electoral divisions – Single Member Constituencies (“SMCs”) and Group Representation Constituencies (“GRCs”). The number of seats in a GRC varies from 4 to 6 seats. The GRC scheme was introduced in 1988 with the goal of promoting greater minority representation. As such, each GRC must have at least one Member of Parliament (“MP”) from a minority racial group. In Wong Souk Yee v AG  SGCA 25, the Court of Appeal (“CA”) addressed the question of whether a by-election for all the seats of the GRC is required when only one MP vacates his or her seat in the GRC. The CA held that a by-election is not required under such circumstances.
