Private Member's Bill
A legislative motion, called a private member's bill, is a proposed law introduced by a member of a legislature.
In Singapore, as in most parliaments within the Westminster System of Parliamentary Democracy, the overwhelming majority of bills introduced are proposed by members of the cabinet, not by individual members of the legislature.
In Singapore an individual member of parliament (MP) is called a private member of parliament (or backbencher) and therefore a legislative motion is called a private member's bill. A private member's bill is not to be confused with a private bill (a bill that only affects an individual citizen or group).
The MP who introduces a legislative motion can be a member of a party represented in the government (cabinet) or in the opposition.
