Song Man Lei worked as a senior local magistrate, later joining Macau's Public Prosecutor Office in 1996. In March 2000, she was appointed Deputy Prosecutor, and served in that role until 2011.[1] She was Macau's first female delegate in the local prosecutor's office.[1]
In 2012, she became the first woman to be appointed as a judge in Macau's highest court, the Court of Final Appeal.[2] She replaced Judge Chu Kim, who died in a car accident in China in 2011.[2]
Along with her duties as a judge, she participated in legal education, teaching at a Chinese judicial training institute (the National Judges College).[1] During her time as a judge on the Court of Final Appeal, she notably prosecuted her former supervisor, prosecutor Ho Chio Meng, for multiple offenses including fraud, money laundering and criminal association, and sentenced him to 21 years in prison along with a significant fine.[3] Song Man Lei had previously worked as an assistant general prosecutor while he headed the Public Prosecutor's Office.[1] During sentencing, Song Man Lei described Ho Chio Meng's conduct as having "tarnished the reputation" of the prosecutor's office.[3] She was also selected twice (in 2011 and 2019) to serve as the Chair of an election committee, whose function is to scrutinize the results of Macau's general election, and manage the electoral process.[4][5]
