Wong Souk Yee v AG (2) [2019] SGCA 25 The Legislature may by law provide for — (a) the vacating of a seat of a non-constituency Member in circumstances other than those specified in Article 46 … … 42 Article 49(2)(a) is worded as a special extension to the grounds provided in Art 46 for the vacating of a Member’s seat. This is apparent from the use of the words “in circumstances other than those specified in Article 46”. This fortifies the conclusion that Art 46 is intended to contain all the grounds for the vacating of parliamentary seats, save for express exceptions made in the Constitution. Other than Art 46 and Art 49(2)(a), no other provisions in the Constitution provide grounds for the vacating of parliamentary seats. 43 Hence, based solely on the words of Art 49, Art 46 and Art 39A, it is unclear whether Art 49(1) may apply to GRCs at all.

Within Art 49(1) itself, the phrase “shall be filled by election” is immediately followed by the phrase “in the manner provided by or under any law relating to Parliamentary elections for the time being in force”. Hence, a question arises as to whether there is any law relating to parliamentary elections that is relevant to the specific situation presented in this case. In this regard, there is no such law. On the contrary, s 24(2A) of the PEA expressly prohibits the holding of a by- 17
