Document 3: Law of the United States: The fifty American states are separate sovereigns, with their own state constitutions, state governments, and state courts. All states have a legislative branch which enacts state statutes, an executive branch that promulgates state regulations pursuant to statutory authorization, and a judicial branch that applies, interprets, and occasionally overturns both state statutes and regulations, as well as local ordinances. They retain plenary power to make laws covering anything not preempted by the federal Constitution, federal statutes, or international treaties ratified by the federal Senate. Normally, state supreme courts are the final interpreters of state constitutions and state law, unless their interpretation itself presents a federal issue, in which case a decision may be appealed to the U.S. Supreme Court by way of a petition for writ of certiorari. State laws have dramatically diverged in the centuries since independence, to the extent that the United States cannot be regarded as one legal system as to the majority of types of law traditionally under state control, but must be regarded as 50 separate systems of tort law, family law, property law, contract law, criminal law, and so on.
Document 4: Lam Kui-chun: Lam Kui-chun, JP (born 20 November 1941, Macau) is a member of the Liberal Party and was the unofficial member of the Legislative Council of Hong Kong (1991—95).
Document 5: Supreme court: In Hong Kong, the Supreme Court of Hong Kong (now known as the High Court of Hong Kong) was the final court of appeal during its colonial times which ended with transfer of sovereignty in 1997. The final adjudication power, as in any other British Colonies, rested with the Judicial Committee of the Privy Council (JCPC) in London, United Kingdom. Now the power of final adjudication is vested in the Court of Final Appeal created in 1997. Under the Basic Law, its constitution, the territory remains a common law jurisdiction. Consequently, judges from other common law jurisdictions (including England and Wales) can be recruited and continue to serve in the judiciary according to Article 92 of the Basic Law. On the other hand, the power of interpretation of the Basic Law itself is vested in the Standing Committee of the National People's Congress (NPCSC) in Beijing (without retroactive effect), and the courts are authorised to interpret the Basic Law when trying cases, in accordance with Article 158 of the Basic Law. This arrangement became controversial in light of the right of abode issue in 1999, raising concerns for judicial independence.

Document 10: Supreme court: While the Philippines is generally considered a civil law nation, its Supreme Court is heavily modelled after the American Supreme Court. This can be attributed to the fact that the Philippines was colonized by both Spain and the United States, and the system of laws of both nations strongly influenced the development of Philippine laws and jurisprudence. Even as the body of Philippine laws remain mostly codified, the Philippine Civil Code expressly recognizes that decisions of the Supreme Court "form part of the law of the land", belonging to the same class as statutes. The 1987 Philippine Constitution also explicitly grants to the Supreme Court the power of judicial review over laws and executive actions. The Supreme Court is composed of 1 Chief Justice and 14 Associate Justices. The court sits either en banc or in divisions, depending on the nature of the case to be decided.
Document 11: Separation of powers under the United States Constitution: The power to review the constitutionality of laws may be limited by Congress, which has the power to set the jurisdiction of the courts. The only constitutional limit on Congress' power to set the jurisdiction of the judiciary relates to the Supreme Court; the Supreme Court may exercise only appellate jurisdiction except in cases involving states and cases affecting foreign ambassadors, ministers or consuls.
Document 12: Judiciary: The judiciary (also known as the judicial system or court system) is the system of courts that interprets and applies the law in the name of the state. The judiciary also provides a mechanism for the resolution of disputes. In most nations, under doctrines of separation of powers, the judiciary generally does not make law (which is the responsibility of the legislature) or enforce law (which is the responsibility of the executive), but rather interprets law and applies it to the facts of each case. In other nations, the judiciary can make law, known as Common Law, by setting precedent for other judges to follow, as opposed to Statutory Law made by the legislature. The Judiciary is often tasked with ensuring equal justice under law.
Document 13: Supreme court: In most nations with constitutions modelled after the Soviet Union, the legislature was given the power of being the court of last resort. In the People's Republic of China, the final power to interpret the law is vested in the Standing Committee of the National People's Congress (NPCSC). This power includes the power to interpret the basic laws of Hong Kong and Macau, the constitutional documents of the two special administrative regions which are common law and Portuguese-based legal system jurisdictions respectively. This power is a legislative power and not a judicial one in that an interpretation by the NPCSC does not affect cases which have already been decided.

He was born in Macau, and, as a child, he moved with his family to Mainland China in 1958, where he remained for the next three decades.
Document 15: Separation of powers under the United States Constitution: An example of the first view is the regulation of attorneys and judges, and the establishment of rules for the conduct of the courts, by the Congress and in the states the legislatures. Although in practice these matters are delegated to the Supreme Court, the Congress holds these powers and delegates them to the Supreme Court only for convenience in light of the Supreme Court's expertise, but can withdraw that delegation at any time.
