A constitutional court is a judicial body with the power to decide whether laws and government actions violate the constitution. In AP Comparative Government, Russia's Constitutional Court is the go-to example, and its president-driven appointment process makes it a weak check on executive power.
A constitutional court is a specialized court whose job is constitutional review. It interprets the constitution and can strike down laws or government actions that conflict with it. That power is what makes the judiciary a real check in a separation-of-powers system, at least on paper.
In AP Comp Gov, the term shows up most often with Russia, which has a Constitutional Court separate from its regular court system. Here's the catch the exam loves. Russian Constitutional Court judges are nominated by the president and confirmed by the Federation Council, a chamber the Kremlin effectively controls. So the institution that's supposed to check the executive owes its seats to the executive. Compare that to the UK, where parliamentary sovereignty means no court can strike down an act of Parliament, or to Iran, where constitutional review of legislation runs through the Guardian Council and Sharia law rather than an independent secular court. The big idea behind this term is the gap between a court's formal powers on paper and its actual independence in practice.
This term lives in Unit 2 (Political Institutions), mainly Topic 2.8 (Judicial Systems) under learning objective AP Comp Gov 2.8.A, which asks you to describe the structure and functions of judiciaries across the six course countries. The essential knowledge (PAU-3.G.1) is all about variation. China runs on rule by law, where courts serve the CPC. Iran's judiciary enforces religious law. Russia has a constitutional court whose appointments flow through the president. A constitutional court is also relevant to Topic 2.5 (Removal of Executives), because courts can be part of the legal machinery that constrains or removes executives who abuse power. If you can explain why a constitutional court exists, who appoints its judges, and whether it can actually say no to the executive, you've hit the core of what Unit 2 wants from judiciaries.

Judicial Review (Unit 2)
Judicial review is the power a constitutional court exercises. The court is the institution; judicial review is what it does. A country can have a constitutional court on paper but hollow judicial review in practice, which is exactly the Russia story.
Separation of Powers (Unit 2)
A constitutional court only checks the other branches if it's independent of them. When the president picks the judges and a loyal legislature confirms them, the check collapses, which is why exam questions ask how Russia's appointment process undermines separation of powers.
Parliamentary Sovereignty (Unit 2)
Parliamentary sovereignty is the opposite arrangement. In the UK, no court can strike down an act of Parliament, so the UK has courts but no constitutional court in the strike-down sense. This contrast is a classic comparative MCQ setup.
Rule of Law vs. Rule by Law (Unit 1)
A constitutional court with real teeth signals rule of law, where even the government is bound by the constitution. China's rule by law flips this. Courts there enforce CPC decisions rather than limit them, so China has no meaningful constitutional review.
Multiple-choice questions tend to target the appointment process and what it does to judicial independence. Expect stems like how Russia's Constitutional Court appointments shape the court's relationship with the executive, which structural feature undermines separation of powers, or which reform would most increase judicial independence. There are also matching-style questions pairing each course country with a distinctive judicial feature (Russia's Constitutional Court, Iran's Sharia-trained judges, China's party-controlled courts, UK's parliamentary sovereignty). On the FRQ side, the 2023 comparative analysis question asked you to compare restrictions on executive power across two course countries, and a constitutional court is exactly the kind of restriction (or failed restriction) that earns points there. The move that scores: don't just say the court exists. Explain whether it can actually constrain the executive, and use the appointment process as your evidence.
A supreme court is the highest appeals court in a regular judicial system; a constitutional court is a separate body that specializes in constitutional review. Russia has both, and only the Constitutional Court rules on constitutionality. The UK's Supreme Court, despite the name, cannot strike down laws at all because of parliamentary sovereignty. Don't assume 'highest court' automatically means 'can declare laws unconstitutional.'
A constitutional court interprets the constitution and can rule laws or government actions unconstitutional, making it a potential check on the executive and legislature.
Russia's Constitutional Court judges are nominated by the president and confirmed by the Federation Council, which ties the court to the executive and weakens its independence.
Having a constitutional court on paper does not guarantee judicial independence in practice; the exam rewards you for spotting that gap.
The UK has no constitutional court power because parliamentary sovereignty means no court can strike down an act of Parliament.
China's rule by law means courts serve the Chinese Communist Party, so there is no meaningful constitutional review of party decisions.
On comparative FRQs, a constitutional court works as evidence for restrictions on executive power, but only if you explain whether the court can actually defy the executive.
It's a court with the authority to interpret the constitution and strike down laws or government actions that violate it. In the AP course, Russia's Constitutional Court is the main example, and the focus is on how its appointment process limits its independence.
No, not in practice. Judges are nominated by the president and confirmed by the Federation Council, which the Kremlin effectively controls, so the court rarely rules against the executive. This formal-power-versus-actual-independence gap is exactly what exam questions test.
A supreme court is the top of the regular appeals system, while a constitutional court is a separate body that specializes in constitutional review. Russia has both, and the UK's Supreme Court can't strike down laws at all because of parliamentary sovereignty.
Because of parliamentary sovereignty. Parliament is the supreme legal authority, so no UK court can declare an act of Parliament unconstitutional. The UK also lacks a single codified constitution for a court to enforce.
Russia has a dedicated Constitutional Court, while Iran's review of legislation is religious in nature and tied to Sharia law. China's judiciary is subservient to the CPC under rule by law, and the UK has no judicial power to strike down laws, so review varies dramatically across the six countries.
