Which principle is exemplified when the House of Representatives brings impeachment charges against a federal judge?

The principle exemplified when the House of Representatives brings impeachment charges against a federal judge is checks and balances. This principle is central to the structure of the U.S. government, which is designed to prevent any one branch from becoming too powerful.

The House of Representatives' ability to impeach a federal judge serves as a check on the judicial branch, ensuring that judges remain accountable for their actions and conduct. This mechanism is part of the broader system where the legislative branch can oversee and limit the power of the judiciary, promoting accountability and maintaining balance among the branches of government.

Checks and balances are crucial for preserving the rule of law and protecting against abuses of power, reinforcing the importance of oversight in a functioning democracy.
