In June, the Education Bureau launched a series of posters as teaching resources for “Constitution” and “Basic Law”. In one of the posters, it stated that the Constitution of the People’s Republic of China applies in Hong Kong; it also stated that Basic Law is not nationwide, so it cannot override Constitution of PRC.
A barrister in Hong Kong suspected the information to be a disparagement of Basic Law, claiming that Constitution of PRC and Basic Law should have the same judicial status in Hong Kong on a legal basis. Only Article 31 of Constitution of PRC is related to the establishment of HKSAR, whereas others are not applicable to Hong Kong.
Moreover, Apple Daily found on the internet that most of the information on that poster copied from a scholar in China supporting Constitution of the People Republic of China.
