Basic Law 第12–23條

Relationship between the Central Authorities and the HKSAR

This chapter establishes that the HKSAR comes directly under the Central People's Government, delineates matters managed by the Central Authorities versus those handled autonomously by the HKSAR, and requires the HKSAR to enact national security legislation on its own.

1 Direct Jurisdiction, Defence and Foreign Affairs

Articles 12–14 establish that the HKSAR comes directly under the Central People's Government; foreign affairs are managed by the Central Government; and defence is the responsibility of the Central Government, which stations garrison forces in Hong Kong.

Direct Jurisdiction and High Degree of Autonomy (Article 12)

第12條
  • The HKSAR is a local administrative region of the PRC which enjoys a high degree of autonomy. Definition
  • The HKSAR comes directly under the Central People's Government (not under any provincial government or the NPC). Exam
  • "Directly under" means the HKSAR is not subordinate to any province, autonomous region or municipality. Trap

易混淆

高頻考點

Distinguish: "foreign affairs" is managed by the Central Government; the HKSAR may handle "external affairs" under authorisation.

How it is examined

Who is responsible for managing foreign affairs relating to the HKSAR?

  • The Central People's Government manages foreign affairs

  • The expenditure for the garrison shall be borne by the Central People's Government (not by the HKSAR Government). Numbers

高頻考點

Key contrast: defence (Central Government) vs public order (HKSAR Government); garrison expenditure borne by the Central Government is a frequent exam point.

易混淆

Garrison personnel must comply with BOTH national laws AND HKSAR laws — not one or the other.

Division of Responsibilities: Central Authorities vs HKSAR

第12–14條

  • Defence is the responsibility of the Central People's Government
  • Public order is the responsibility of the HKSAR Government

2 Appointments, Legislative Filing and National Laws

Articles 15–18 cover the Central Government's appointment of the Chief Executive and principal officials, the mechanism for filing HKSAR legislation with the NPCSC, and the Annex III system for applying national laws in Hong Kong.

Appointment of Chief Executive and Principal Officials (Article 15)

第15條
  • The Central People's Government shall appoint the Chief Executive and the principal officials of the executive authorities of the HKSAR in accordance with Chapter IV of the Basic Law. Exam
  • The appointment is governed by Chapter IV (Political Structure), specifically Articles 43–48 for the Chief Executive and Article 60 for principal officials. Definition

高頻考點

Frequent fill-in exam: "Who appoints the Chief Executive?" — answer is the Central People's Government, not the NPC, NPCSC or State Council.

How it is examined

The Chief Executive of the HKSAR is appointed by ____?

  • Appointed by the Central People's Government
  • NOT appointed by the National People's Congress
  • NOT appointed by the NPCSC
  • Principal officials are also appointed by the Central People's Government

Legislative Filing System (Article 17)

第17條
  • The HKSAR is vested with legislative power. Definition
  • Laws enacted by the HKSAR legislature must be reported to the Standing Committee of the National People's Congress (NPCSC) for the record. Exam
  • Filing for the record does not affect the entry into force of the law (laws take effect upon enactment, not upon approval). Trap
  • After consulting the HKSAR Basic Law Committee, the NPCSC may return (but not amend) any HKSAR law that is inconsistent with the provisions of the Basic Law relating to matters within the responsibility of the Central Authorities or the relationship between the Central Authorities and the HKSAR. Exam
  • A returned law takes effect immediately upon return, and shall have no retroactive effect unless otherwise provided by HKSAR laws. Exam

高頻考點

Frequent fill-in: "The NPCSC may ___ the law, but not amend it" — answer is "return". A returned law takes immediate effect as void but has no retroactive force.

易混淆

Common mistake: filing does not affect validity — no approval needed. The NPCSC may only return, not amend. Both points appear directly in exam questions.

How it is examined

A law returned by the NPCSC will ____.

  • Take immediate effect as void
  • Have no retroactive effect unless otherwise provided by HKSAR laws
  • Is not amended by the NPCSC
  • Filing does not affect the entry into force of the law

The NPCSC may return an HKSAR law if it is inconsistent with provisions relating to ____.

Annex III: National Laws Applied in Hong Kong (Article 18)

第18條
  • Laws applied in the HKSAR are: the Basic Law itself, Hong Kong's pre-existing laws, and laws enacted by the HKSAR legislature. Definition
  • National laws shall not be applied in the HKSAR unless they are listed in Annex III of the Basic Law. Exam
  • National laws listed in Annex III shall be applied locally by way of promulgation or legislation by the HKSAR. Exam
  • The NPCSC may add to or delete from Annex III after consulting the Basic Law Committee and the HKSAR Government; any law added must be limited to those relating to defence, foreign affairs and other matters outside the HKSAR's autonomy. Exam
  • In the event of a declaration of a state of war, or due to turmoil endangering national unity or security beyond the control of the HKSAR Government leading to a declaration of a state of emergency, the Central People's Government may issue an order applying relevant national laws in the HKSAR. Exam

高頻考點

Frequent fill-in: "Laws in Annex III are limited to those relating to ____" — answer is defence, foreign affairs and matters outside HKSAR autonomy. "External affairs" is a distractor.

易混淆

Easy mistake: adding/removing from Annex III requires consulting BOTH the Basic Law Committee AND the HKSAR Government — not just the HKSAR Government.

必背數字

Emergency state: the NPCSC makes the declaration of emergency; the Central People's Government issues the order to apply national laws — two different institutions, two different roles.

必背數字

Frequent fill-in: "prohibit ____ from conducting political activities in HKSAR" — answer is "foreign political organisations or bodies" (not "any" political body). Also tested: HKSAR political bodies must not establish ties with "foreign" political bodies.

常見失分位

Exam format: fill in the missing prohibited act. Common distractors are "interfering in foreign affairs", "calling for international sanctions" — none are listed in Article 23. The correct answer is "theft of state secrets".

易混淆

Common mistake: Article 23 prohibits "subversion of the Central People's Government", not "state power". "Foreign" political organisations is distinct from "any" political organisation. The HKSAR enacts the laws itself.
