Final answer:
Article III ensures that federal judges' compensation cannot be reduced during their service, ensuring judicial independence.
Step-by-step explanation:
Article III guarantees that the compensation of federal judges will not be reduced during their service on the bench. This provision ensures the independence of the judiciary by protecting federal judges from potential financial coercion by the legislative or executive branches of government. The framework established by Article III allows judges to serve on good behavior, typically interpreted as a lifetime appointment unless they are impeached, and it prevents the diminishing of their compensation during their time in office. The intent of this protection is to maintain an independent and impartial judiciary, free from undue political influence that could potentially arise if their salary were subject to alteration.
