Lau Kong Yung v. Director of Immigration was a 1999 right of abode case in the Hong Kong Court of Final Appeal following closely on the heels of the landmark Ng Ka Ling v. Director of Immigration decision earlier that year. After Ng and the two prior actions in Lau, but before the case came before the CFA, the Standing Committee of the National People's Congress (NPCSC) of the People's Republic of China issued an interpretation of the Basic Law which affected the rights of Lau and his fellow applicants. Lau thus became the first case in which the CFA had to take into account an NPCSC interpretation in applying the Basic Law.
