As of December 2010, one NMP – Professor Walter Woon Cheong Ming, a law lecturer at the National University of Singapore – had succeeded in having a public law enacted based on a private member's bill he or she had initiated. The law in question is the Maintenance of Parents Act, which entitles parents at least 60 years old and unable to maintain themselves adequately to apply to a tribunal for their children to be ordered to pay maintenance to them. The bill was introduced in Parliament by Woon on 23 May 1994, and eventually passed on 2 November 1995. In that year, the first woman NMP, Dr. Kanwaljit Soin, also introduced a Family Violence Bill but it did not pass.
