Three proposals for minority representation in Parliament had been considered by a 1966 Constitutional Commission chaired by the Chief Justice Wee Chong Jin. The first was to have a committee of representatives of minorities that would elect three persons from amongst its members to represent minorities in Parliament. However, this was rejected as the Commission felt that it would be an inappropriate and retrogressive move in that unelected members should not be allowed to dilute the elected chamber. The second proposal, which was to have proportional representation, was also rejected on the grounds that it would intensify party politics along racial lines and eventually "perpetuate and accentuate racial differences". This would then make it increasingly difficult, if not impossible, to achieve a single homogeneous community out of the many races that form the population of the Republic. The third proposal was to have an upper house in Parliament composed of members elected or nominated to represent the racial, linguistic and religious minorities in Singapore. However, this was rejected as being backward-looking since politicians should attain a seat in Parliament through taking part in elections.
