Final answer:
The Supreme Court's power of judicial review establishes it as a coequal branch of government, allowing it to check the actions of the other branches by ensuring they adhere to the Constitution. However, its power is balanced by internal and external factors, reliance on the other branches for enforcement, and public scrutiny.
Step-by-step explanation:
The concept of judicial review elevates the Supreme Court to a coequal branch of government. This power, which was established in the case of Marbury v. Madison in 1803, allows the Court to invalidate laws and actions by the other branches of government if they are found to be unconstitutional. While the original Constitution did not explicitly state this power, it has become a crucial part of the checks and balances system, ensuring that the judiciary can check the legislative and executive branches.
Beyond judicial review, the Supreme Court's influence is also shaped by various internal and external factors, including the justices' ideologies, political climates, and public opinion. These factors, along with the need for implementation and enforcement by the other branches, are part of the system of checks and balances that prevent any one branch from becoming too powerful. The Supreme Court may have limitations but remains a vital component in interpreting the Constitution and maintaining the balance of power.
While the judicial branch is considered coequal, its power is different in nature from the legislative and executive branches. The court does not have the power to enforce its decisions; this is dependent on the executive branch, highlighting a reliance within the separation of powers. Moreover, the Supreme Court justices' work is subject to scrutiny by those within the legal field, the media, and the public. These mechanisms ensure the accountability of the Court and illustrate the dynamic interplay between the governmental branches.
