Hong Kong law is characterized by a mixture of legal sources and traditions, originating from the constitutional government-based structure in the mid-1800s to the new laws, which were promulgated at the beginning of the 20th century. Since Hong Kong’s return into the People’s Republic of China in 1997, the development and forms of the Hong Kong Special Administrative Region Laws have been influenced by the Constitution of the People’s Republic of China of 1982, the Sino-British Joint Declaration of Hong Kong issues of 1984 as well as the Basic Law of the Hong Kong Special Administrative Region of 1990. The government of China continues to undertake measures, promoting a high degree of autonomy within the Hong Kong as well as its political stability and economic prosperity. All these measures contribute to the promotion of the rule of law and unification of China.
