Between 1993 and 2006, he was the chairman of Electoral Affairs Commission which is responsible for running and supervising elections in Hong Kong shortly after Chris Patten became Hong Kong's last Governor and established the electoral organ. He handled the first three Chief Executive elections, which were won by Tung Chee-hwa and Donald Tsang, in which he had to face public scrutiny and also interpret election rules. He was criticised for allowing Tung to do his electioneering while still in office as Chief Executive in 2002. As a senior judge, he led a number of historic public independent inquiries, including the inquiry into the Garley Building inferno in 1996 and the chaotic opening of the new airport in 1998. In August 2006, Woo took up the post of Commissioner on Interception of Communications and Surveillance soon after retiring as the EAC chairman, in which he served until 2012. In March 2007, he was appointed by Chief Executive Donald Tsang as the head of the commission to investigate allegations over meddling with the academic freedom and autonomy of educational institutions involving the proposed merger of the Hong Kong Institute of Education and the Chinese University of Hong Kong. He resigned after less than a week to avoid potential accusations of lack of impartiality due to his working relationship with Fanny Law, former Permanent Secretary for Education and Manpower.
2017 Chief Executive campaign
Woo became the first candidate to declare his campaign on 27 October 2016. He launched an offensive campaign against incumbent Chief Executive Leung Chun-ying, questioning his achievements during his term, while Woo himself was questioned for his lack of experience in public administration. On 14 December, Woo Kwok-hing unveiled his electoral platform under the slogan of "Righteous heart, righteous way, revert Hong Kong back to right track". He proposed to expand the voter base for choosing the Election Committee to one million in the 2022 Chief Executive election from the current 250,000, rising to three million by 2032 and eventually quasi-universal suffrage. His attendees included Andy Ho On-tat, former information coordinator during the Donald Tsang administration from 2006 to 2012. He later updated his platform adding the proposal of legislating Hong Kong Basic Law Article 22 which prohibiting mainland Chinese authorities for "meddling" in Hong Kong affairs as Beijing's Liaison Office in Hong Kong had been accused of meddling with the city's elections. Woo made an emergency plea for support after getting just three nominations on the first day of the nomination period. As the "Democrats 300+" planned to nominate John Tsang and Woo Kwok-hing to boost the competitiveness of the election against Beijing's favoured candidate Carrie Lam, Woo gradually received nominations from pro-democrat electors. Six electors from the Higher Education subsector including Civic Party founding chairman Kuan Hsin-chi became the first pro-democrats decided to nominate Woo on 15 February. 46 pro-democrat members from seven Election Committee also decided to nominate Woo on 18 February. After Tsang received enough nominations, pro-democrats turned to help Woo. On 27 February, Woo became the second candidate to be nominated, with 180 nominations in which almost all of them came from the pro-democracy camp. Woo received only 21 votes in the 1,194-member Election Committee in the final election, becoming the lowest votes a Chief Executive candidate ever had, as his pro-democrat nominators switched side to John Tsang in order to boost Tsang's chance of winning.
