Supreme Court decisions are final

A) because other political actors automatically abide by them.
B) as they cannot be checked by other political institutions.
C) but depend on the support of other institutions to be carried out.
D) because they are always clear, thereby leaving little room for discretion in implementation.

Supreme Court decisions, while final in the legal sense, often require the cooperation and support of other branches of government or local authorities to be effectively implemented. This interdependence underscores the checks and balances system inherent in the U.S. political structure, where no single branch operates in isolation or without potential constraint by the others.
