12. Which of the following principles was established by the United States Supreme Court in the 1803 Marbury v. Madison decision, making the Supreme Court a coequal branch of government?
Answer: B
Judicial review
The principle established by the United States Supreme Court in the 1803 Marbury v. Madison decision is judicial review, which allows the Supreme Court to invalidate laws and actions that are inconsistent with the Constitution.
A) Separation of powers
While separation of powers is a fundamental constitutional principle that divides government responsibilities among the legislative, executive, and judicial branches, it was not specifically established by the Marbury v. Madison decision. This case focused on the authority of the judiciary to review and nullify governmental actions.
B) Judicial review
Judicial review is the correct answer as it was the key principle affirmed in Marbury v. Madison. The Court asserted its authority to review acts of Congress and determine their constitutionality, thereby solidifying its role as a coequal branch of government.
C) Republicanism
Republicanism refers to the ideology of governing a society as a republic, emphasizing the role of citizens in electing representatives. This principle was not addressed in the Marbury v. Madison case and does not relate to the establishment of the Court's power.
D) Freedom of speech
Freedom of speech is a right protected by the First Amendment of the U.S. Constitution, but it was not a principle established in the Marbury v. Madison decision. This case dealt specifically with the judiciary's power rather than individual rights.
Conclusion
Judicial review is the definitive principle established in Marbury v. Madison, which positioned the Supreme Court as an essential check on legislative power. The other options, while significant in their own right, do not pertain to the specific judicial authority conferred by this landmark decision. Thus, B is the only correct answer in the context of the question.
