Final answer:
To maintain an independent judiciary, it is important to have a separation of powers, appoint judges for life tenure, and grant the power of judicial review.
Step-by-step explanation:
In order for the judiciary to remain independent, there are several key factors to consider. First, the separation of powers is crucial to ensure that the judiciary is not influenced by other branches of government. Additionally, the appointment of federal judges for life tenure helps to protect them from political interference and pressures. Finally, the power of judicial review allows the judiciary to protect the rights of minority groups and uphold the principles of the Constitution.
