Hong Kong's politics: an autonomy granted by a law Beijing interprets

What the Basic Law grants and what it keeps

The Basic Law is a national law. The National People's Congress adopted it on 4 April 1990 and it took effect on 1 July 1997, as the constitutional document of a region created under Article 31 of China's constitution. Its first article states that the region is an inalienable part of the People's Republic of China, and Article 12 makes it a local administrative region coming directly under the Central People's Government. Inside that frame the grant is wide. Article 2 gives the region executive, legislative and independent judicial power, including final adjudication. Article 5 says the socialist system will not be practised there and that the previous capitalist system and way of life will remain unchanged for 50 years. Article 8 keeps the common law, and Article 9 lets English be used beside Chinese as an official language.

What the central government keeps is listed as plainly.

The last two rows on the right have done most of the work since 1997. The Standing Committee of the National People's Congress issued interpretations on the right of abode in 1999, on the procedure for changing the electoral methods in 2004, on the term of a chief executive replacing one who resigned in 2005, on foreign affairs in a case involving the Democratic Republic of the Congo in 2011 and on the oaths of newly elected legislators in 2016. Hong Kong's courts follow those interpretations, and Annex III is how the 2020 security law reached the region.

How Beijing and London read the arrangement

The arrangement began as a treaty. Under the Sino-British Joint Declaration of 19 December 1984, the Chinese government set out its basic policies for Hong Kong, and the Basic Law's preamble says those policies are elaborated in the declaration. The British government reads the declaration as guaranteeing that for 50 years from 1997 the region would enjoy a high degree of autonomy, except in foreign and defence affairs, with executive, legislative and independent judicial power. It reports to Parliament every six months against the declaration's first annex, and since the electoral overhaul of March 2021 it has assessed China to be in a state of ongoing non-compliance.

Beijing's account is set out in a white paper issued by the State Council Information Office on 20 December 2021. It holds that there was no democracy under British rule, that China established democracy in Hong Kong after resuming the exercise of sovereignty, and that an extended period of unrest caused by anti-China agitators inside and outside the region had to be ended by strengthening the central authorities' overall jurisdiction, legislating for national security and modifying the electoral system so that patriots govern Hong Kong. The explanatory material printed with the May 2021 edition of the Basic Law quotes Deng Xiaoping's definition from June 1984: a patriot is "one who respects the Chinese nation, sincerely supports the motherland's resumption of exercise of sovereignty over Hong Kong, and wishes not to impair Hong Kong's prosperity and stability".

The Hong Kong government's own yearbook adopts Beijing's terms: the electoral ordinance that took effect on 31 May 2021 is there to ensure that the system upholds the principle of 'one country, two systems' and that 'patriots administering Hong Kong' is fully implemented, and the district council reform of 2023 is described in the same words. The two readings agree on the period. Article 5 of the Basic Law and the British reading of the declaration both run 50 years from 1997. Neither sets out what follows, and the legal scholar Albert Chen holds that the Basic Law itself has no expiry date and stays valid unless amended.

How the chief executive is chosen

The chief executive heads both the region and its government and, under Article 43, is accountable to the Central People's Government and to the region. Article 45 sets the ultimate aim of selection by universal suffrage on nomination by a broadly representative committee. In practice an Election Committee chooses and the Central People's Government appoints.

Annex I, as amended by the Standing Committee on 30 March 2021, fixes the committee at 1,500 members in five sectors of 300: industrial, commercial and financial; the professions; grassroots, labour, religious and other groups; members of the Legislative Council and district bodies; and Hong Kong's deputies to the National People's Congress and members of the Chinese People's Political Consultative Conference. The white paper of 2021 records the change from 1,200 members in four sectors. A candidate needs nominations from at least 188 members, including at least 15 from each sector, and the winner needs more than 750 votes in a secret ballot.

Before any of that, a Candidate Eligibility Review Committee confirms who may stand. The Committee for Safeguarding National Security, acting on a review by the national security department of the police, tells it whether a candidate meets the requirement of upholding the Basic Law and swearing allegiance to the region, and no legal proceedings may be brought against its decisions. In the selection of May 2022 there was one candidate.

How the Legislative Council is formed now

The council elected under British rule in 1995 was the first wholly elected one, and from 2004 half of its seats were directly elected, according to Britannica. Annex II as rewritten on 30 March 2021 enlarged it from 70 seats to 90 and divided them three ways. Every candidate, whatever the route, needs nominations from at least two and at most four members of each Election Committee sector, as well as clearance by the review committee.

The British government's report on the second half of 2025 gives the detail of the election of 7 December 2025, the second under the new rules. Around 1.32 million votes elected the 20 directly chosen members, 51 candidates stood for them, and media reports counted about 41,000 invalid ballots, 3% of the vote. The report says that, as in 2021, no pro-democracy candidates took part, and that the Democratic Party, which it describes as the oldest pro-democracy party, voted to disband on 14 December 2025. After voting, electors were handed government cards thanking them, which could be exchanged for free museum entry, shopping vouchers, cinema discounts and health checks, and some employers gave staff half a day off on showing one.

The council has defeated the government once since 2021. On 10 September 2025 it rejected the Registration of Same-sex Partnerships Bill, the first government bill defeated since the 2021 overhaul. The bill answered a ruling of the Court of Final Appeal in September 2023 that the lack of any framework for recognising same-sex partnerships was unconstitutional.

What the national security laws cover

Article 23 of the Basic Law requires the region to legislate on its own against treason, secession, sedition, subversion and the theft of state secrets. An attempt in 2003 failed after mass protests. On 28 May 2020 the National People's Congress decided that the Standing Committee should legislate instead, and the Law on Safeguarding National Security in the Hong Kong Special Administrative Region was passed on 30 June 2020, listed in Annex III and in force at 11 pm the same night. It has 66 articles and four offences: secession, subversion, terrorist activities and collusion with a foreign country or external elements. It created a Committee for Safeguarding National Security chaired by the chief executive with an adviser designated by the central government, an Office for Safeguarding National Security of the Central People's Government in Hong Kong, and judges designated by the chief executive to hear its cases.

The region then legislated under Article 23 after all. The Legislative Council passed the Safeguarding National Security Bill on 19 March 2024 and the ordinance took effect on 23 March. It adds five categories of offence, which the UN human rights office lists as treason, insurrection, offences connected with state secrets and espionage, sabotage endangering national security, and external interference. The Congressional Research Service notes that it allows extended pretrial detention and limits on consultation with lawyers in national security cases.

The positions on both laws are stated by their authors. The Hong Kong government's fact sheets say the 2020 law plugged a loophole in national security and targets "an extremely small minority" while protecting the rights of the overwhelming majority, and that the 2024 ordinance had very wide support and aligns with international practice. The UN High Commissioner for Human Rights, Volker Türk, said on 19 March 2024 that the bill was rushed through despite serious concerns about its compatibility with international human rights law, calling its adoption "a regressive step". Human Rights Watch noted that the council took 11 days to pass it unanimously. The British government counted 69 national security arrests in 2025, including for displaying political slogans, peaceful protest and organising petitions.

How the courts keep the common law

The courts are the part of the arrangement that has changed least in form. Hong Kong's law remains common law, judges may refer to precedents from other common law jurisdictions, and the Court of Final Appeal, set up in 1997, has power of final adjudication. Non-permanent judges from other common law jurisdictions sit on it: the British government counted six at the end of 2025, two from the United Kingdom, three from Australia and one from New Zealand, and ten overseas non-permanent judges who had left or retired since June 2020.

The limits sit above the courts. Article 158 gives interpretation of the Basic Law to the Standing Committee, and the 2020 law lets mainland criminal procedure apply to cases the Office for Safeguarding National Security takes over. National security trials are heard by the designated judges.

How the district councils were rebuilt

Hong Kong's 18 districts each have a council. In November 2019, months into the protests, the district elections drew more than 2.94 million votes and a turnout of 71.2%. The District Councils (Amendment) Ordinance 2023, in force from 10 July 2023, rebuilt them as advisory and service bodies which, in the government's words, are not organs of political power.

The reformed councils have 470 seats: 179 members appointed by the chief executive, 176 returned by district committees constituencies, 88 elected in geographical constituencies and 27 ex officio seats held by the chairmen of the rural committees of the New Territories. Each council is chaired by the district officer, who represents the government in the district, and candidates must be approved by a District Council Eligibility Review Committee.

Who Hong Kong deals with abroad

Foreign affairs belong to Beijing, whose foreign ministry keeps an office in Hong Kong under Article 13, but the Basic Law leaves the region an external life of its own in economic and cultural matters. As "Hong Kong, China" it is a member of the World Trade Organization and of Asia-Pacific Economic Cooperation, issues its own passports, runs a customs border with the mainland and maintains economic and trade offices abroad and in mainland cities, including Chengdu, Guangdong, Shanghai and Wuhan. The People's Liberation Army garrison is responsible for defence and, under Article 14, may not interfere in local affairs; the regional government may ask for its help in maintaining public order and in disaster relief. Hong Kong sends 36 deputies to the National People's Congress.

The security law changed how other governments treat the region. After June 2020 the United Kingdom, Canada, Australia, New Zealand, Finland and Ireland suspended their extradition treaties with Hong Kong, and in July 2020 the United States ended the preferential economic and trade treatment it had given Hong Kong apart from the rest of China. The British government confirmed on 30 July 2025 that its treaty remains suspended. How the region's economy has fared alongside these changes is the subject of Hong Kong: economy.
