The USA follows a federal system, where the judiciary operates on two levels: federal and state courts. The U.S. supreme court is the highest authority, followed by appellate courts and district courts. The judiciary enjoys strong independence, with judges, especially at the federal level, being appointed for life, ensuring they are not easily influenced by political changes. The U.S. system also includes the practice of judicial review, where courts can invalidate laws and executive actions that violate the Constitution.
India's judiciary is similarly structured with the supreme court at the top, followed by High Courts at the state level and subordinate courts. indian judges are appointed through a collegium system, a unique method where senior judges play a key role in judicial appointments. Unlike the U.S., indian judges do not serve for life; they retire at a set age (65 for supreme court judges).
Both systems uphold the principle of the separation of powers, but India's judiciary is often seen as more active in governance through public interest litigation (PIL), while the U.S. courts are more restrained in intervening in policy matters.
