Which power is often controversial because they are based on interpretation?

The power of judicial review is often controversial because it relies heavily on the interpretation of laws and the Constitution. Courts, particularly the Supreme Court, can determine the constitutionality of legislative and executive actions, which can lead to significant political and social implications. This interpretative nature can result in varying outcomes based on the judges' philosophies and perspectives, leading to debates over judicial activism versus restraint. Such decisions can provoke strong reactions from different political factions and the public.
