See joined the Singapore Legal Service in 1991 and was appointed as a Deputy Registrar and Magistrate in the Subordinate Courts (now State Courts).[2] From 1995 to 1997, he served as a Justices' Law Clerk before becoming a District Judge in 1998. As a District Judge, he heard a variety of cases in the criminal, civil and family courts until 2007, when he became Head of the Insolvency and Public Trustee's Office. In November 2009, See was reappointed as a District Judge and subsequently made Senior District Judge, heading the Criminal Justice Division of the Subordinate Courts.
During his tenure as District Judge, See presided the robbery trial of Ragu Ramajayam, who was the secondary mastermind of a S$1.3 million mobile phone heist, during which Ragu's colleague Wan Cheon Kem was robbed and brutally killed by Ragu's accomplices. See sentenced 37-year-old Ragu to six years in prison and 12 strokes of the cane, after taking into account that Ragu breached his position of trust and his role in the heist itself had led to the murder of Wan.[3] Ragu's sentence was later reduced to 4+1⁄2 years in jail and six strokes of the cane after he appealed. In the aftermath, one of Ragu's accomplices Nakamuthu Balakrishnan was given the death sentence for murder while the remaining three were given jail terms and caning for armed robbery with hurt.[4]
On 1 October 2013, See became the Chief District Judge of the Subordinate Courts.[5] During this time, he also served as a member of a committee to guide the development of the Singapore University of Social Sciences's School of Law.[6] On 14 April 2014, he was appointed as a Judicial Commissioner and Presiding Judge of the State Courts. On 31 January 2017, he was promoted to Judge of the Supreme Court.[7][8] He was subsequently appointed as a Judge of the Appellate Division in October 2023.[9]
One case presided by See was the 2021 trial of Gaiyathiri Murugayan, who was charged with the abuse and murder of Piang Ngaih Don, a Myanmar national who was her domestic maid. Gaiyathiri was found guilty of culpable homicide not amounting to murder and voluntarily causing hurt to the maid, and sentenced to a total of 30 years' imprisonment. See described the case as one of the worst cases of culpable homicide Singapore has ever seen, and described that the degree of callousness and violence was so shocking that no suitable words could adequately describe the inhumane year-long mistreatment, assault and starvation, which the maid was subjected to.[10]
In July 2018, See was also the presiding judge of a female drug trafficker's case for diamorphine trafficking. The female trafficker, Saridewi Djamani, was charged with one count of smuggling 30.72g of diamorphine and she put up a defense that she only meant to traffic less than half of the drugs while leaving the remaining majority portion for her personal use during the Muslim fasting month Ramadan. See rejected Saridewi's claims since she had attempted to downplay the scale of her criminal activities and was inconsistent with her evidence regarding her daily drug intake in both her police statements and court testimony. Since Saridewi was not acting as a courier, she was sentenced to death upon her conviction for diamorphine trafficking. Saridewi's Malaysian accomplice Muhammad Haikal Abdullah was jointly tried and later sentenced to life imprisonment and caning (15 strokes) by See on the same date of Saridewi's sentencing. Five years later, 45-year-old Saridewi was executed on 28 July 2023, becoming the first female offender to be put to death, 19 years after the Yen May Woen case in 2004.[11][12][13]
See was also the judge who heard the last-minute appeals by two Malaysian drug traffickers Pannir Selvam Pranthaman and Nagaenthran K. Dharmalingam in 2020 and 2021 respectively, as they sought to reopen their cases and delay their executions. Both Pannir and Nagaenthran lost their appeals and remained on death row since, and out of the two, Nagaenthran was initially set to be executed on 10 November 2021 before it was delayed due to Nagaenthran tested positive for COVID-19.[14][15][16] Nagaenthran was hanged on 27 April 2022.[17]
In May 2023, See sentenced an 86-year-old Singaporean man to 15 years in jail for the "deliberately and unspeakably vicious and brutal" killing of his 79-year-old live-in partner Lim Soi Moy, with whom the man had four children. The convicted killer, Pak Kian Huat, had hacked Lim to death with a chopper after he was angered by Lim's refusal to let him sleep in a bigger bedroom at their flat in Toa Payoh in 2019, and he pleaded guilty after his original charge of murder was lowered to manslaughter. See, in sentencing Pak to the jail term proposed by the prosecution, admonished Pak for his lack of remorse and the brutality of his attack on Lim over a trivial matter of perceived grievances, and he also stated that the advanced age of Pak did not count as a factor to shorten his sentence in view of the heinous act, which would have attracted life imprisonment.[18]
