The existing Constitution of the People's Republic of China (The Constitution) was adopted at the Fifth Session of the Fifth National People's Congress on 4 December 1982. The Constitution is the fundamental and supreme law of the state. As an important symbol and sign of the nation, it has the highest legal status, legal authority, as well as legal effect.
The Constitution is the "root" and "origin" of the Hong Kong Special Administrative Region (HKSAR). Article 31 of the Constitution stipulates that "The state may establish special administrative regions when necessary". Article 62 of the Constitution also stipulates that the National People's Congress shall exercise the power to decide on the establishment of special administrative regions and the systems to be instituted there. It is based on the stipulations from the Constitution that the HKSAR is established. The Constitution gives the legislative backing and source of power for the Basic Law, and provides a solid legal basis and constitutional framework to the basic policies of "one country, two systems", "Hong Kong people administering Hong Kong" and a high degree of autonomy.
With the aim of enhancing public awareness of the Constitution, promoting its spirit, strengthening its implementation and advancing China's overall law-based governance, the Standing Committee of the Twelfth National People's Congress decided at the Eleventh Session on 1 November 2014 to designate 4 December as the "Constitution Day" and that the nation will conduct promotion and education activities of the Constitution through multiple channels.
To deepen public understanding of the constitutional basis of Hong Kong, the Hong Kong Special Administrative Region Government will organise a seminar on the Constitution Day, with the Liaison Office of the Central People's Government in the Hong Kong Special Administrative Region and the Endeavour Education Centre being supporting organisations. The seminar, with the theme of "The Constitution and National Security", will analyse the important concept of national security, explore the relationship between the Constitution and the Law of the People's Republic of China on Safeguarding National Security in the Hong Kong Special Administrative Region (National Security Law) and national security, as well as examine how the Constitution and the National Security Law effectively safeguard the country’s sovereignty, security and development interests. Details of the seminar are as follows:
