The Basic Law (BL) is the constitutional document of the Hong Kong Special Administrative Region (HKSAR). Put into effect on July 1, 1997, it enshrines within a legal document the important concept of “One Country, Two Systems.”
Q: Are Mainland laws applicable to Hong Kong?
A: Generally speaking, national laws of mainland China are not applied in the HKSAR. Article 18(2), (3) and (4) of the Basic Law provide for application of national laws in the HKSAR. Such national laws as applied in the HKSAR shall be listed in Annex III to the Basic Law. Currently, a total of 12 national laws are so listed in Annex III, all of which concern matters outside the limits of the HKSAR's autonomy. They include national laws on the capital, calendar, national anthem, national flag, national day, national emblem, territorial sea and contiguous zone, exclusive economic zone and continental shelf, nationality, garrisoning, diplomatic and consular privileges and immunities as well as judicial immunity of assets of foreign central banks.
