Kwok, however, said he hasn't thought of migration, instead moved to Bela Vista Villa of outlying island Cheung Chau for retirement in 1996.

In 2017 Kwok said he believed Hong Kong no longer enjoyed rule of law and is planning to migrate to Britain.

In 2022, he achieved his second success after the High Court ruled the Hong Kong government does not have the power to void more than 20,000 COVID-19 vaccination exemption certificates issued by doctors allegedly handed them out without conducting proper medical consultation,[14] despite the verdict was effectively overturned by the government days later.

[15] Kwok, a formal member of Democratic Party, has been under attack from Beijing mouthpieces, accused by Ta Kung Pao of colluding with "anti-China" pro-democracy camp.

[16] After sixteen years with over 60 filings of judicial review but winning less than 10 of those, Kwok revealed his intention to end his activism under fear of crackdown and arrest by authorities.
