Interpretation, Amendment, Supplementary Provisions and the Three Annexes

Chapter VIII vests interpretation authority in the NPCSC and amendment authority in the NPC; Chapter IX (Supplementary Provisions) provides transitional arrangements for pre-existing laws. The three Annexes govern the methods for selecting the Chief Executive and forming the Legislative Council (comprehensively revised in 2021) and the national laws applied in Hong Kong — the highest-frequency chapters in the BLNST.

1 Power of Interpretation (Article 158)

Interpretation authority belongs to the NPCSC; Hong Kong courts are authorised to interpret autonomy provisions when adjudicating cases; when a case requires interpretation of provisions relating to central affairs or central–SAR relations and that interpretation affects the outcome, the Court of Final Appeal must refer to the NPCSC before giving a final judgment; the NPCSC consults the Basic Law Committee before issuing an interpretation; judgments given before publication of an interpretation are not affected.

Ultimate Interpretation Authority: NPCSC

第158條第1款
  • The power of interpretation of the Basic Law is vested in the Standing Committee of the National People's Congress (NPCSC). Exam
  • The NPCSC authorises the courts of the HKSAR to interpret, on their own, provisions of the Basic Law that concern affairs within the autonomy of the HKSAR when adjudicating cases. Exam
  • When adjudicating cases, courts of the HKSAR may also interpret other provisions of the Basic Law (i.e. provisions outside the autonomous scope). Trap
  • However, if interpretation of a provision concerning affairs managed by the Central Authorities or the relationship between the Central Authorities and the HKSAR is needed and the interpretation affects the outcome of a case, the Court of Final Appeal shall, before making its final judgment of no further appeal, request the NPCSC to give an interpretation. Exam
  • The body that makes the referral is specifically the Court of Final Appeal (not any other court), and the referral must be made before the final judgment, not after. Trap

高頻考點

Ultimate interpretation power belongs to the NPCSC — courts only interpret by authorisation. True exam questions frequently test this as a fill-in-the-blank: answer is NPCSC, not the Court of Final Appeal, not the LegCo.

程序考點

The four-step referral procedure is a true exam question pattern: (1) CFA requests NPCSC interpretation → (2) NPCSC consults Basic Law Committee → (3) NPCSC issues interpretation → (4) HK courts apply the interpretation in the final judgment. The referring body is specifically the CFA, and referral must be before the final judgment.

易混淆

Three conditions must all apply before the CFA must refer: (1) provision concerns central affairs or central–SAR relations; (2) interpretation affects the judgment; (3) before giving a final judgment of no further appeal.

Division of Interpretation Powers

第158條
Body Scope of interpretation Key limit
NPCSCAll provisions (ultimate power)Must consult the Basic Law Committee before interpreting
HK courts (on their own)Provisions within HKSAR autonomyAuthorised by the NPCSC to interpret on their own
HK courts (other provisions)May also interpret other provisionsIf it concerns central affairs / central–SAR relations and affects the judgment, the CFA must refer to the NPCSC before the final judgment

Ultimate interpretation power rests with the NPCSC (not the CFA); courts interpret autonomous provisions only by authorisation.

How it is examined

According to Article 158, which body holds the power to interpret the Basic Law?

  • The Standing Committee of the National People's Congress (NPCSC)
  • Courts only interpret by authorisation from the NPCSC
  • Provisions on HKSAR autonomous affairs may be interpreted by courts themselves
  • Provisions on central affairs must, in specified circumstances, be referred to the NPCSC by the CFA

Under what circumstances must the Court of Final Appeal refer a Basic Law provision to the NPCSC for interpretation?

  • The provision concerns affairs managed by the Central Authorities or the central–SAR relationship
  • The interpretation of that provision affects the outcome of the case
  • The referral must be made before delivering a final judgment of no further appeal
  • The referring body is the Court of Final Appeal specifically

What is the effect of an NPCSC interpretation on judgments already given before the interpretation is published?

  • Judgments already given before the interpretation is published shall not be affected
  • This protects the legitimate expectations of existing litigants
  • Hong Kong courts shall, when applying the provision, follow the NPCSC interpretation

What is the correct procedural order after the CFA refers a provision for NPCSC interpretation?

  • Step 1: The Court of Final Appeal requests the NPCSC to give an interpretation
  • Step 2: The NPCSC consults the Basic Law Committee
  • Step 3: The NPCSC gives an interpretation of the provision
  • Step 4: Hong Kong courts apply the interpretation in giving the final judgment

Consultation with the Basic Law Committee Before Interpretation

第158條第4款
  • Before giving an interpretation of the Basic Law, the NPCSC shall consult its Committee for the Basic Law of the HKSAR (Basic Law Committee). Exam
  • The Basic Law Committee is a working committee under the NPCSC, comprising twelve members in total — six from the mainland and six from Hong Kong. Definition
  • Consulting the Basic Law Committee is a procedural requirement, but ultimate interpretation authority still belongs to the NPCSC; the Committee's opinion is not binding. Trap

高頻考點

Before interpreting, the NPCSC must consult the "Basic Law Committee" — not the CE, not the LegCo. The Basic Law Committee is under the NPCSC, comprising 12 members (6 mainland, 6 Hong Kong). True exam questions frequently ask its size or its parent body.

How it is examined

Before interpreting the Basic Law, which body must the NPCSC consult?

  • The Committee for the Basic Law of the HKSAR (Basic Law Committee)
  • The Basic Law Committee is under the NPCSC
  • Consultation is a procedural requirement; the opinion is not binding
  • Ultimate interpretation authority remains with the NPCSC

How many members does the Basic Law Committee have and which body does it fall under?

  • Twelve members in total
  • Under the Standing Committee of the National People's Congress (NPCSC)
  • Six mainland members and six Hong Kong members
  • Provides opinions to the NPCSC on issues relating to implementation of the Basic Law

2 Power of Amendment (Article 159) and Supplementary Provisions (Article 160)

Amendment authority belongs to the NPC; three parties may propose amendments (NPCSC, State Council, HKSAR); HKSAR proposals require two-thirds of HKSAR NPC deputies, two-thirds of all LegCo members, and CE consent; proposals reviewed by the Basic Law Committee before inclusion in NPC agenda; no amendment may contravene the established basic policies. Article 160 provides transitional arrangements for pre-existing laws at the establishment of the SAR.

Amendment Authority: National People's Congress

第159條
  • The power to amend the Basic Law is vested in the National People's Congress (NPC) — not the NPCSC. Exam
  • The right to propose amendments belongs to three bodies: the NPCSC, the State Council, and the HKSAR. Exam
  • An amendment proposal from the HKSAR requires the consent of two-thirds of HKSAR deputies to the NPC, two-thirds of all members of the HKSAR LegCo, and the Chief Executive of the HKSAR, before the HKSAR delegation to the NPC submits it to the NPC. Numbers
  • Any amendment bill shall, before inclusion in the agenda of the NPC, be studied by the Basic Law Committee, which shall submit its opinion. Exam
  • No amendment to the Basic Law shall contravene the established basic policies of the PRC regarding Hong Kong. Exam

常見失分位

Key distinction: interpretation power = NPCSC; amendment power = NPC (full Congress). MC frequently tests this distinction.

必背數字

HKSAR amendment proposal: three requirements — (1) two-thirds HKSAR NPC deputies, (2) two-thirds of all LegCo members, (3) CE consent — then submitted by the HKSAR delegation to the NPC.

Interpretation → NPCSC (Standing Committee); amendment → NPC (full Congress) — the most-tested trap.

How it is examined

Which body holds the power to amend the Basic Law?

  • The National People's Congress (NPC)
  • Not the NPCSC
  • Proposals may come from the NPCSC, State Council, or HKSAR
  • No amendment may contravene the established basic policies on Hong Kong

What consents are required for the HKSAR to propose an amendment to the Basic Law?

  • Two-thirds majority of HKSAR deputies to the NPC
  • Two-thirds majority of all members of the HKSAR LegCo
  • Consent of the Chief Executive of the HKSAR
  • Submitted by the HKSAR delegation to the NPC after all three are obtained

Which body must study an amendment bill before it is included in the NPC agenda?

  • The Committee for the Basic Law of the HKSAR
  • The Committee studies the bill and submits its opinion
  • This is a procedural requirement to be completed before inclusion in the NPC agenda

Supplementary Provisions: Transition of Pre-existing Laws (Article 160)

第160條
  • Upon the establishment of the HKSAR, the laws previously in force in Hong Kong shall be adopted as the laws of the HKSAR unless the NPCSC declares them to be in contravention of the Basic Law. Exam
  • If any laws are subsequently found to be in contravention of the Basic Law, they may be amended or cease to be in force in accordance with the procedures prescribed in the Basic Law. Exam
  • Documents, certificates, contracts, rights and obligations that were valid under the previous laws of Hong Kong shall remain valid and be recognised and protected by the HKSAR, provided they do not contravene the Basic Law. Exam
  • Article 160 is the sole Article in Chapter IX (Supplementary Provisions) and provides the legal transitional arrangements at the establishment of the SAR. Definition

高頻考點

Supplementary Provisions: pre-existing laws are adopted by default; only the NPCSC can declare them contrary — not the CE or LegCo. Also note the clause protecting pre-existing documents, certificates, contracts, rights and obligations — they "remain valid and are recognised and protected by the HKSAR" if not in contravention.

How it is examined

How were the pre-existing laws of Hong Kong treated upon the establishment of the HKSAR?

  • Adopted as HKSAR laws unless declared contrary to the Basic Law by the NPCSC
  • Declaration of contravention is made by the NPCSC, not the CE or LegCo
  • If later found to contravene, they may be amended or cease to be in force
  • Pre-existing documents, certificates, contracts, rights and obligations remain valid if consistent with the Basic Law

3 Annex I: Method for Selecting the Chief Executive (Revised 2021)

Revised and passed by the NPCSC on 30 March 2021. The Election Committee was enlarged from 1,200 to 1,500 members across five sectors of 300 each; candidates need nominations from at least 188 members with no fewer than 15 from each sector; elected by secret ballot of the committee, requiring more than 750 votes; a Candidate Qualification Review Committee is established and its decisions cannot be challenged by legal proceedings; modification of this method requires two-thirds of all LegCo members, CE consent, and approval by the NPCSC.

Composition of the Election Committee (1,500 Members, Five Sectors)

附件一
  • The Election Committee comprises a total of 1,500 members with a term of five years. Numbers
  • Five sectors of 300 members each: Sector 1 — Industrial, commercial and financial sectors; Sector 2 — The professions; Sector 3 — Grassroots, labour and religious sectors; Sector 4 — Members of the LegCo, representatives of district organisations, etc.; Sector 5 — HKSAR NPC deputies, HKSAR CPPCC members, and representatives of relevant national bodies. Numbers
  • Election Committee members vote in their individual capacity, each having one vote (one person, one vote). Exam
  • The Election Committee is responsible for electing the Chief Executive and also for electing 40 members of the Legislative Council (see Annex II). Exam

必背數字

Key numbers: 1,500 members = 5 sectors × 300 per sector; term = 5 years. MC often tests total size or per-sector count.

高頻考點

Know all five sector names. MC may ask "which of the following is NOT an Election Committee sector". Sector 5 (NPC deputies, CPPCC members and mainland-related bodies) is a key 2021 addition.

How it is examined

According to the revised Annex I (2021), how many members does the Election Committee have?

  • A total of 1,500 members
  • Five sectors, 300 members per sector
  • Term: five years
  • Vote in their individual capacity, one person one vote

What are the five sectors of the Election Committee?

  • Sector 1: Industrial, commercial and financial sectors
  • Sector 2: The professions
  • Sector 3: Grassroots, labour and religious sectors
  • Sector 4: LegCo members and representatives of district organisations, etc.
  • Sector 5: HKSAR NPC deputies, HKSAR CPPCC members, and representatives of relevant national bodies

Nomination Threshold and Election Threshold for Candidates

附件一
  • Chief Executive candidates must obtain nominations from no fewer than 188 Election Committee members, with no fewer than 15 members from each of the five sectors participating in the nomination. Numbers
  • The Election Committee elects the Chief Executive-designate by secret ballot on a one-person-one-vote basis; a candidate must obtain more than 750 votes to be elected. Numbers
  • The Chief Executive-designate is appointed by the Central People's Government to become the official Chief Executive. Exam
  • 188 nomination votes = 1,500 × 12.5% (over one-eighth); 750 election votes = 1,500 × 50% (over one-half). Numbers

必背數字

Key numbers: nomination threshold = 188 (min 15 per sector); election threshold = MORE THAN 750 (i.e. 751+, not "750 or above"). MC tests exact wording.

常見失分位

Nomination has two simultaneous requirements: (1) total no fewer than 188, and (2) at least 15 from each of the five sectors. Both must be satisfied.

How it is examined

How many Election Committee nominations must a Chief Executive candidate obtain?

  • No fewer than 188 Election Committee members
  • With no fewer than 15 members from each of the five sectors
  • Both conditions must be satisfied simultaneously

How many votes must a Chief Executive candidate obtain in the Election Committee vote to be elected?

  • More than 750 votes
  • By secret ballot on a one-person-one-vote basis
  • More than 750 means 751 or above
  • With 1,500 members in total, more than 750 means a majority

Candidate Qualification Review Committee and Annex I Modification Procedure

附件一
  • A Candidate Qualification Review Committee is established to examine and confirm the qualifications of candidates for Election Committee membership and for Chief Executive. Exam
  • The Candidate Qualification Review Committee shall examine candidate qualifications based on a review opinion from the Committee for Safeguarding National Security of the HKSAR, which is based on a review by the national security department of the Police Force. Exam
  • Decisions made by the Candidate Qualification Review Committee on confirmation of candidate qualifications shall not be subject to legal proceedings. Exam
  • Power to amend Annex I (as revised in 2021, Art. 10): exercised by the NPCSC in accordance with law; before making an amendment, the NPCSC shall listen to the views of various sectors of Hong Kong society in an appropriate manner. Exam
  • Old vs new: before 2021, amendment required a two-thirds LegCo majority + CE consent + NPCSC approval (Annex I) / filing (Annex II). Since the 2021 revision, the power to amend both annexes is unified and exercised by the NPCSC — the LegCo two-thirds, CE consent, and the approval-vs-filing distinction no longer apply. Compare

新舊制對比

Since the March 2021 revision, the power to amend Annex I (Art. 10) and Annex II (Art. 8) is unified and exercised by the NPCSC, which listens to Hong Kong views before amending. The old "two-thirds LegCo + CE consent" process and the "approval vs filing" distinction have been abolished — a frequently updated exam point.

高頻考點

Qualification Review Committee decisions cannot be challenged by legal proceedings — a key new provision. MC may ask whether such decisions are subject to judicial review.

How it is examined

Under the 2021-revised Annex I, which body exercises the power to amend the method for selecting the Chief Executive?

  • Exercised by the NPCSC in accordance with law
  • Before amending, it listens to Hong Kong views in an appropriate manner
  • The old "two-thirds LegCo + CE consent + NPCSC approval" process was abolished in 2021

Can decisions of the Candidate Qualification Review Committee on the qualification of CE candidates be challenged by legal proceedings?

  • No — shall not be subject to legal proceedings
  • Provided in the 2021 revised Annex I
  • The Committee acts based on a review opinion from the NSC and national security police unit

4 Annex II: Method for Forming the LegCo (Revised 2021) and Annex III

After the 2021 revision, LegCo membership increased from 70 to 90: 40 elected by the Election Committee, 30 by functional constituencies, and 20 by geographical direct election (ten constituencies, 2 seats each, double-seat single-vote system); a Candidate Qualification Review Committee is established; modification only requires filing with the NPCSC. Annex III lists national laws applied in Hong Kong (currently 13); additions and deletions are decided by the NPCSC after consulting the Basic Law Committee and HKSAR Government.

LegCo 90-Seat Composition (2021 New System)

附件二
  • Each term of the HKSAR Legislative Council shall have 90 members: 40 elected by the Election Committee, 30 by functional constituencies, and 20 by geographical direct election. Numbers
  • Geographical direct election is conducted in ten constituencies, each returning two members; each voter casts one vote for a candidate, and the two candidates with the most votes are elected (double-seat single-vote system)。 Numbers
  • The 40 LegCo members elected by the Election Committee are elected by the same 1,500-member Election Committee that selects the Chief Executive. Exam
  • LegCo candidate qualifications are likewise examined and confirmed by the Candidate Qualification Review Committee, and its decisions shall not be subject to legal proceedings. Exam
  • Two voting procedures: (1) Government bills — passed by a simple majority of members present; (2) Individual member bills, motions and amendments — must be passed separately by a majority of EACH of two groups: (a) functional constituency members, and (b) Election Committee and geographical direct election members. Exam

必背數字

90 seats = 40 (Election Committee) + 30 (functional) + 20 (geographical). Previous system: 70 seats (30 functional + 40 geographical). 2021 change: added 40 EC seats, geographical reduced from 40 to 20.

易混淆

Double-seat single-vote: each geographical constituency returns 2 members but each voter casts only 1 vote. MC often tests this voting system.

高頻考點

High-frequency true question: two different voting rules — government bills need only a simple majority of members present; individual member bills/amendments must be passed by a majority of EACH of two groups separately. True questions test the fill-in "各過半數" vs simple majority.

Key Numbers: Annexes I & II

"More than 750" means 751+; nomination must satisfy BOTH the 188 total and the 15-per-sector minimum.

How it is examined

According to the revised Annex II (2021), how many seats does the LegCo have and how are they distributed?

  • Total: 90 seats
  • Election Committee elections: 40 seats
  • Functional constituency elections: 30 seats
  • Geographical direct elections: 20 seats

What voting system is used for the geographical direct election component of the LegCo?

  • Double-seat single-vote system
  • Ten constituencies, each returning two members
  • Each voter casts only one vote
  • The two candidates with the most votes are elected

What voting procedure is required for bills and amendments proposed by individual LegCo members?

  • Must be passed separately by a majority of each of two groups of members present
  • Group 1: members elected by functional constituencies
  • Group 2: members elected by the Election Committee and by geographical direct election
  • Government bills only require a simple majority of members present — a different rule

Annex II Modification Power and Old-vs-New Comparison

附件二
  • Power to amend Annex II (as revised in 2021, Art. 8): the NPCSC exercises, in accordance with law, the power to amend this method and the procedures for voting on bills and motions; before amending, it listens to the views of various sectors of Hong Kong society in an appropriate manner. Exam
  • The power to amend Annexes I and II is now unified: both are exercised by the NPCSC. The pre-2021 distinction ("Annex I approval vs Annex II filing") and the "two-thirds LegCo + CE consent" process have been abolished. Compare

新舊制對比

"Approval vs filing" was a pre-2021 comparison and no longer applies. The power to amend Annex I (Art. 10) and Annex II (Art. 8) is now unified under the NPCSC — treat any "two-thirds LegCo / CE consent / approval / filing" wording as the superseded old regime.

Annex Amendment: Pre-2021 vs Current

Revised 30 Mar 2021, effective 31 Mar 2021; amendment power for both annexes is unified under the NPCSC, and the approval-vs-filing distinction is abolished.

How it is examined

Under the 2021-revised Basic Law, which body exercises the power to amend Annex I and Annex II?

  • Both are exercised by the NPCSC in accordance with law
  • Before amending, it listens to Hong Kong views in an appropriate manner
  • The pre-2021 "Annex I approval / Annex II filing" and "two-thirds LegCo + CE consent" distinctions were abolished

Annex III: National Laws Applied in the HKSAR

附件三
  • Annex III currently lists 13 national laws applied in the HKSAR (by way of promulgation or local legislation). Numbers
  • The 13 national laws currently in Annex III: (1) Resolution on the national capital, era, anthem and flag; (2) Resolution on National Day; (3) Government Statement on Territorial Sea; (4) Nationality Law; (5) Diplomatic Privileges and Immunities Ordinance; (6) National Flag Law; (7) Consular Privileges and Immunities Ordinance; (8) National Emblem Law; (9) Territorial Sea and Contiguous Zone Law; (10) Garrison Law for HKSAR; (11) Exclusive Economic Zone and Continental Shelf Law; (12) National Anthem Law; (13) National Security Law for HKSAR. Exam
  • Laws in Annex III are limited to those relating to defence, foreign affairs and other matters outside the scope of the HKSAR's autonomy. Definition
  • Additions to or deletions from Annex III are decided by the NPCSC after consulting the Basic Law Committee and the Government of the HKSAR. Exam
  • When the NPCSC decides to declare a state of war, or decides that the HKSAR shall enter a state of emergency due to uncontrollable turmoil threatening national unity or security, the Central People's Government may issue orders applying national laws not listed in Annex III to the HKSAR. Exam

高頻考點

Two key Annex III exam points: (1) additions/deletions decided by NPCSC (not the full NPC); (2) must consult the Basic Law Committee and HKSAR Government beforehand.

易混淆

Annex III only covers national laws on defence, foreign affairs and matters outside HKSAR autonomy — not all national laws automatically apply. The NSL (Law 13) was added in June 2020.

高頻考點

True exam question: in a state of war or emergency, national laws beyond Annex III may be applied in HK — and it is the "Central People's Government" (not the NPCSC) that issues the order. MC tests the trigger condition and the issuing body.

How it is examined

What category of matters must national laws in Annex III relate to?

  • Defence, foreign affairs and matters outside the HKSAR's autonomy
  • Not all national laws automatically apply in Hong Kong
  • Annex III currently lists 13 national laws

Which body decides on additions to or deletions from Annex III, and which bodies must be consulted first?

  • Decided by the NPCSC
  • Must first consult the Basic Law Committee
  • Must also consult the HKSAR Government
  • Note: the NPCSC (not the full NPC) makes this decision

Which of the following national laws is currently listed in Annex III of the Basic Law?

  • National Anthem Law of the PRC
  • Nationality Law of the PRC
  • Garrison Law for the HKSAR
  • National Security Law for the HKSAR (added 2020)
  • Diplomatic Privileges and Immunities Ordinance of the PRC

Under what circumstances may national laws beyond Annex III be applied to the HKSAR, and which body issues the order?

  • Trigger 1: The NPCSC decides to declare a state of war
  • Trigger 2: The NPCSC decides the HKSAR shall enter a state of emergency due to uncontrollable turmoil threatening national unity or security
  • The order is issued by the Central People's Government (not the NPCSC)
  • Outside these emergencies, national laws beyond Annex III do not apply in the HKSAR
