Kasiviswanathan Shanmugam (ta|காசிவிஸ்வநாதன் சண்முகம்|translit=Kācivisvanātaṉ Caṇmukam; born 26 March 1959),[3] better known as K. Shanmugam, is a Singaporean politician and lawyer who has been serving as Minister for Law since 2008 and Minister for Home Affairs since 2015. A member of the governing People's Action Party (PAP), he has been the Member of Parliament (MP) representing the Chong Pang division of Nee Soon GRC since 2011.
A lawyer by profession, Shanmugam made a name for himself in litigation, arbitration and insolvency cases before he entered politics. In 1998, at the age of 38, he was one of the youngest lawyers in Singapore to be appointed Senior Counsel. Along with Davinder Singh, he was known as one of the "twin titans of litigation" and a prominent figure in Singapore's legal circles.[4] [5] Shanmugam has also received praise for being one of the top cross-examiners in Singapore and has acted for and against all three prime ministers in civil lawsuits.[6]
Shanmugam was educated at Raffles Institution from 1972 to 1977. He went on to read law at the National University of Singapore's Faculty of Law and graduated in 1984.
During his time in law school, Shanmugam earned several awards, book prizes and scholarships for being the top student from his first to third years and for academic merit (1982–1983). He also won the Montrose Memorial Prize for Jurisprudence (1984).[7]
Shanmugam was awarded the Adrian Clarke Memorial Medal, the Leow Chia Heng Prize and the External Examiner's Prize (1984) for being the top law student of his graduating class and top student in the final-year examinations. He also represented Singapore in the Philip C. Jessup International Law Moot Court Competition in 1984, in which his team won Runner-Up in the International Division.[8]
After being admitted to the Singapore Bar as an advocate and solicitor in 1985, Shanmugam went into private practice and became a senior partner and Head of Litigation and Dispute Resolution at Allen & Gledhill.
In 1998, Shanmugam became one of the youngest lawyers to be appointed Senior Counsel of the Supreme Court at the age of 38.[9]
Shanmugam has acted for Singapore's Prime Minister Lee Hsien Loong and his predecessors (Lee Kuan Yew and Goh Chok Tong) in lawsuits. In 1995, the International Herald Tribune selected Shanmugam to represent them after the Lees and Goh initiated a civil libel lawsuit against the newspaper. Lee Kuan Yew later stated that the Tribunes decision to choose Shanmugam to represent them even though he was a People's Action Party member and was close to the Lees and Goh, was the highest form of praise to the Senior Counsel's integrity and to the integrity of the Singapore Government as a whole.[10]
At the age of 29, Shanmugam entered politics when he joined the People's Action Party (PAP) team contesting in Sembawang GRC in the 1988 general election. The PAP team won and Shanmugam was elected the Member of Parliament representing the Chong Pang division of Sembawang GRC.
Shanmugam served as a Member of Parliament and continued to practise law until 2008 when he joined the Cabinet to replace S. Jayakumar as Minister for Law.[11] He was concurrently appointed Second Minister for Home Affairs in 2008, and succeeded Wong Kan Seng as Minister for Home Affairs in 2010.
Following the 2011 general election, Shanmugam relinquished his portfolio as Minister for Home Affairs and was appointed Minister for Foreign Affairs, while continuing to serve concurrently as Minister for Law.[12] As of 2015, Shanmugam remains as a Member of Parliament representing Chong Pang ward, which had become part of Nee Soon GRC.[13]
Following Shanmugam's remarks on changes to the qualifying criteria for Singapore's elected presidency, he was criticised by former presidential candidate Tan Cheng Bock for pre-empting the legislative process and the Presidential Elections Committee, which decides the eligibility of candidates for the presidential election.[14]
In February 2018, Shanmugam said that Singapore would change its criminal breach of trust (CBT) laws to address concerns that company directors and key officers of charities would face lower maximum penalties for CBT offences compared to their employees.[15]
Shanmugam was a member of the Select Committee on Deliberate Online Falsehoods formed in 2018. During the public hearings, he questioned Simon Milner, Facebook's Vice President of Public Policy for Asia-Pacific, about the misuse of online data by Cambridge Analytica., and crossed swords with historian Thum Ping Tjin over a paper about Operation Coldstore written by Thum in 2013.[16]
In 2023, Shanmugam and Vivian Balakrishnan were investigated by the Corrupt Practices Investigation Bureau for their rentals of state-owned bungalows at Ridout Road. The CPIB subsequently found that neither Shanmugam nor Balakrishnan had committed any wrongdoing.[17]
This has been the basis for making Singapore's laws more compassionate, with greater collectivism, and to make the country look out for those who are unable to look after themselves.[18]
During Shanmugam's tenure as Minister for Law, some changes to the criminal and family justice system were effected. These include:
Shanmugam served on the board of directors for several companies before his appointment to the Singapore Cabinet.
Shanmugam served as the President of the Singapore Indian Development Association (SINDA) from March 2002 to March 2009.
Shanmugam has been married to clinical psychologist Dr. Seetha Subbiah since 2008. He was formerly married to Jothie Rajah, daughter of KS Rajah. They later divorced.[28]
Shanmugam is a practising Hindu. He is also often involved in various religious activities organised by communities of various faiths. He has met Pope Francis in the Vatican City and has referred to the Pontiff as exemplifying the "essence of religion" and a "strong advocate of interfaith dialogue and understanding".[29]
Shanmugam also participates regularly in the Taoist Nine Emperor God's festival in his Constituency since he became an MP for the area.[30]
