HK National Security Law 第1–6條

General Principles

Chapter I sets out the legislative purpose, responsible parties, human rights safeguards and rule-of-law principles of the NSL — the foundational framework of the entire law, effective **30 June 2020**.

1 Legislative Purpose and Background

Article 1 sets out the seven purposes for enacting the NSL and confirms its legal basis in the Constitution, the Basic Law and the relevant NPC decision.

Legislative Purposes (Article 1)

第1條
  • The NSL is enacted in accordance with the Constitution, the Basic Law and the relevant NPC decision. Definition
  • Purpose 1: Ensure the resolute, full and faithful implementation of the policy of One Country, Two Systems under which the people of Hong Kong administer Hong Kong with a high degree of autonomy. Exam
  • Purpose 2: Safeguard national security. Exam
  • Purpose 3: Prevent, suppress and impose punishment for the four offences: secession, subversion, terrorist activities, and collusion with a foreign country or external elements. Exam
  • Purpose 4: Maintain the prosperity and stability of the HKSAR.
  • Purpose 5: Protect the lawful rights and interests of HKSAR residents.
  • Legislative procedure: NPC passed the authorising decision on 28 May 2020; NPCSC passed the NSL on 30 June 2020, gazetted and entered into force on the same day. Numbers

高頻考點

The four offences are high-frequency exam material. Remember the order: secession → subversion → terrorist activities → collusion.

常見失分位

The effective date "30 June 2020" is frequently tested directly; do not confuse it with 1 July (Handover anniversary).

Four Offences Endangering National Security

第1條
No. Offence
1Secession
2Subversion of State power
3Organising and carrying out terrorist activities
4Collusion with a foreign country or external elements

Exact wording: "subversion of State power" (not "of government"); "terrorist activities" (not "espionage").

  • The Constitution, the Basic Law and the relevant NPC decision
  • NPC passed the authorising decision on 28 May 2020
  • NPCSC passed the NSL on 30 June 2020, with immediate effect
  • Implemented in Hong Kong after being added to Annex III of the Basic Law

  • Subversion of state power; organising and carrying out terrorist activities (exact wording)
  • Not "rebellion" or "espionage activities"
  • Four offences — not fewer

  • Gazetted and added to Annex III of the Basic Law on the same day
  • NPC authorised on 28 May 2020; NPCSC passed on 30 June 2020

2 Fundamental Provisions and Responsible Parties

Article 2 designates Basic Law Articles 1 and 12 as fundamental provisions; Article 3 clarifies the division of national security responsibilities between the Central Authorities and the HKSAR.

Fundamental Provisions (Article 2)

第2條
  • Basic Law Article 1 (the HKSAR is an inalienable part of the PRC) and Article 12 (the HKSAR is a local administrative region directly under the CPG, enjoying a high degree of autonomy) are the fundamental provisions of the Basic Law. Exam
  • No institution, organisation or individual shall contravene the provisions of Basic Law Articles 1 and 12 in the exercise of rights and freedoms in the HKSAR. Exam
  • The fundamental provisions refer only to Article 1 (territorial sovereignty) and Article 12 (political status), not all provisions of the Basic Law. Trap

易混淆

Remember it is "Articles 1 AND 12" together as fundamental provisions — not Article 1 alone, and not the entire Basic Law.

How it is examined

Basic Law Articles 1 and 12 concerning the legal status of the HKSAR are the _____ of the Basic Law.

  • Fundamental provisions (not "basic provisions" or "supreme provisions")
  • Article 1: The HKSAR is an inalienable part of the PRC
  • Article 12: The HKSAR is a local administrative region directly under the CPG
  • Two articles only — not three or all provisions

Any institution, organisation or individual in the HKSAR shall not, in exercising _____, contravene Basic Law Articles 1 and 12.

  • Rights and freedoms (not just "rights" or "duties")
  • Applies to: any institution, any organisation, any individual
  • Binding whenever rights and freedoms are exercised in the HKSAR
  • Contravening either Article 1 or Article 12 is not permitted

Division of Responsibilities: Central Authorities and HKSAR (Article 3)

第3條
  • The Central People's Government has an overarching responsibility for national security affairs relating to the HKSAR. Exam
  • The HKSAR has a constitutional duty to safeguard national security and shall fulfil its responsibilities in that regard. Exam
  • The HKSAR executive, legislative and judicial bodies shall, in accordance with the NSL and other relevant laws, effectively prevent, suppress and impose punishment for acts and activities endangering national security. Exam
  • Central Authorities bear "overarching responsibility" vs HKSAR bears "constitutional duty" — the two terms differ and are a common trap. Compare

易混淆

Central = "overarching responsibility"; HKSAR = "constitutional duty" — different terms, a must-know comparison.

高頻考點

Real exams often fill-in-blank: "executive, legislative and judicial bodies" must all prevent, suppress and punish — not just the executive.

Division of Responsibilities: Central Authorities vs HKSAR

第3條
Body Responsibility Content
Central People's GovernmentOverarching responsibilityNational security affairs relating to the HKSAR
HKSARConstitutional responsibilityFulfil its duty to safeguard national security
HKSAR executive, legislative, judicial bodiesPerform dutiesEffectively prevent, suppress and punish acts endangering national security

Central = "overarching" responsibility; HKSAR = "constitutional" responsibility — a classic trap.

How it is examined

The Central People's Government bears _____ for national security affairs relating to the HKSAR.

  • Overarching responsibility (not "supreme", "constitutional" or "important" responsibility)
  • Scope: "national security affairs relating to the HKSAR", not all affairs
  • Central and HKSAR responsibility differ in nature and must not be confused

The HKSAR bears a _____ to safeguard national security; the HKSAR _____, _____ and _____ shall prevent, suppress and punish acts endangering national security.

  • Constitutional duty (not overarching responsibility)
  • Executive, legislative and judicial bodies (all three, none omitted)
  • Verb phrase: "prevent, suppress and punish" (not "resolve and penalise")
  • Legal basis: the NSL and other relevant laws

3 Human Rights and Rule of Law Principles

Article 4 requires that human rights be respected and protected in safeguarding national security, including rights under the Basic Law and two international covenants; Article 5 establishes five rule-of-law principles.

Protection of Human Rights (Article 4)

第4條
  • Safeguarding national security shall respect and protect human rights. Definition
  • Rights and freedoms enjoyed by residents under the Basic Law and the provisions applicable to Hong Kong of the International Covenant on Civil and Political Rights (ICCPR) and the International Covenant on Economic, Social and Cultural Rights (ICESCR) shall be protected. Exam
  • Protected freedoms include: freedom of speech, freedom of the press, freedom of publication, freedom of association, freedom of assembly, freedom of procession and freedom of demonstration. Exam
  • Article 4 references two international covenants: ICCPR and ICESCR. Numbers

必背數字

The two covenants are frequently tested: one covers civil and political rights (ICCPR), the other covers economic, social and cultural rights (ICESCR).

高頻考點

Seven protected freedoms: speech → press → publication → association → assembly → procession → demonstration. Exactly seven, not six or eight.

The Two International Covenants under Article 4

第4條
Covenant Abbr. Rights covered
International Covenant on Civil and Political RightsICCPRCivil and political rights
International Covenant on Economic, Social and Cultural RightsICESCREconomic, social and cultural rights

Article 4 cites two covenants (as applicable to Hong Kong) — not the Universal Declaration of Human Rights, and not just one.

How it is examined

Safeguarding national security shall respect and protect rights under the Basic Law and _____ and _____ as applicable to Hong Kong.

  • International Covenant on Civil and Political Rights (ICCPR)
  • International Covenant on Economic, Social and Cultural Rights (ICESCR)
  • Two covenants — not one or three
  • "Provisions applicable to Hong Kong" — not the full text of the covenants

The NSL explicitly protects: (i) speech, press, publication; (ii) association; (iii) assembly, procession; (iv) demonstration. Which are protected?

  • All four — (i), (ii), (iii) and (iv) — are protected
  • Cannot select only some of them
  • Seven freedoms: speech, press, publication, association, assembly, procession, demonstration
  • These freedoms are protected alongside national security — not curtailed by it

Five Rule-of-Law Principles (Article 5)

第5條
  • The principle of the rule of law shall be adhered to in preventing, suppressing and imposing punishment for offences endangering national security. Definition
  • Principle 1 (Legality): A person shall be convicted and punished in accordance with law for an act that constitutes an offence under the law; no one shall be convicted and punished for an act that does not constitute an offence under the law. Exam
  • Principle 2 (Presumption of Innocence): A person is presumed innocent until convicted by a judicial body. Exam
  • Principle 3 (Right to Defence): The right to defend himself or herself and other rights in judicial proceedings of a criminal suspect, defendant and other parties shall be protected. Exam
  • Principle 4 (Double Jeopardy): No one shall be tried or punished again for the same act for which he or she has already been finally convicted or acquitted in judicial proceedings. Exam
  • Article 5 establishes four specific rule-of-law principles: legality, presumption of innocence, right to defence, and double jeopardy. Numbers

必背數字

The four rule-of-law principle names are must-knows: legalitypresumption of innocenceright to defencedouble jeopardy.

常見失分位

"Presumption of innocence" applies until convicted by a judicial body, not the executive or police.

Rule-of-Law Principles under Article 5

第5條
Principle Core content
LegalityNo conviction or punishment for an act not defined as an offence by law
Presumption of innocencePresumed innocent until convicted by a judicial body
Right to defenceRight to defend and litigation rights of suspects and defendants are protected
Double jeopardyNo retrial or punishment for the same act after final adjudication

The overarching principle is the "rule of law"; the four specific principles below must all be memorised.

How it is examined

Preventing, suppressing and punishing offences endangering national security shall adhere to _____. Where the law does not provide for an offence, no one shall _____.

  • Adhere to "the principle of the rule of law" (not "national security principle")
  • Where no offence is provided by law: "shall not be convicted and punished"
  • All three goals — prevention, suppression, punishment — must adhere to this principle
  • This is the core of the legality (罪刑法定) principle

No one shall be convicted until a _____ has found him guilty; once finally adjudicated, no one shall be tried again for _____.

  • Not convicted until a "judicial body" rules — not the executive or police
  • Cannot be tried again for "the same act" (double jeopardy / 一事不再審)
  • Criminal suspects and defendants are guaranteed the right to defend and other litigation rights
  • Four principles: legality → presumption of innocence → right to defence → double jeopardy

4 Common Duty and Oath of Allegiance

Article 6 establishes safeguarding national sovereignty as a common duty of all Chinese people, and requires HKSAR residents to take an oath or sign a confirmation when standing for election or taking up public office.

Common Duty and Compliance with the NSL (Article 6)

第6條
  • Safeguarding national sovereignty, unity and territorial integrity is the common responsibility of all the people of China, including the people of Hong Kong. Exam
  • Any institution, organisation or individual in the HKSAR shall comply with the NSL and other HKSAR laws for safeguarding national security, and shall not engage in acts and activities endangering national security. Exam
  • HKSAR residents who stand for election or take public office shall, in accordance with the law, sign a document to confirm or take an oath to uphold the Basic Law of the HKSAR of the PRC and pledge allegiance to the HKSAR of the PRC. Exam
  • The oath requirement applies to those standing for election AND those taking up public office — not only those already elected. Trap
  • The duty to comply applies to any institution, organisation or individual in Hong Kong — not only HKSAR residents. Trap

常見失分位

Both "standing for election" and "taking public office" trigger the oath/confirmation requirement — not only upon taking office.

高頻考點

The common responsibility applies to "all people of China, including the people of Hong Kong" — the inclusion of Hong Kong people is an exam focus.

Three Duties under Article 6

第6條

The oath applies to both standing for election AND taking office; the duty to comply binds any institution, organisation or individual — not only residents.

How it is examined

Safeguarding national _____, _____ and _____ is the _____ of all the people of China, including the people of Hong Kong.

  • Sovereignty, unity and territorial integrity (all three, in order)
  • Subject: "all the people of China, including the people of Hong Kong" — not just mainland residents
  • Nature: "common responsibility" (not "constitutional duty" or "overarching responsibility")

HKSAR residents who _____ or _____ shall sign a confirmation or take an oath to uphold _____ and pledge allegiance to the HKSAR of the PRC.

  • Uphold the "Basic Law of the HKSAR of the PRC" (not the NSL itself)
  • Allegiance pledged to: "the HKSAR of the PRC"
  • Confirmation document "or" oath — either mode satisfies the requirement

  • Scope: the NSL and other HKSAR laws for safeguarding national security
