In a commentary, SMU Associate Professor of Law Eugene Tan shared his opinion that too much has been made of People’s Action Party (PAP) and Workers’ Party (WP) contrasting approaches regarding their party whips and found that focus should centre on what MPs on both sides said — individually and collectively —whether for or against the repeal and the related Constitutional amendment to protect the definition of marriage. He concluded that Tuesday’s outcome in Parliament would probably not be different even if the whip had been lifted for PAP MPs, and this reflects the shifting social attitudes of Singaporeans.
