Final answer:
The U.S. Constitution established a system of checks and balances, with justices on the Supreme Court protected by lifetime appointments to ensure judicial independence from the other branches of government.
Step-by-step explanation:
The constitution established a system of checks and balances to make sure that no one branch has too much power. Justices are protected by the lifetime appointment.
The concept of checks and balances is a foundational principle of the United States Constitution. It ensures that the three branches of government - legislative, executive, and judicial - can limit each other and prevent any single branch from becoming overly powerful. The judicial branch, which includes the Supreme Court, plays a critical role in this system by interpreting the Constitution and the laws of the land. Justices on the Supreme Court are appointed for life, according to Article III of the Constitution, to maintain an independent judiciary and safeguard it from political pressures that could threaten its ability to uphold the law and protect individual rights.
