In a democracy, the responsibility for interpreting constitutional law typically lies with the judiciary, particularly with the supreme or constitutional courts. These institutions are entrusted with safeguarding the Constitution and ensuring that legislation aligns with constitutional principles. Judicial rulings set precedents that shape the understanding of rights, liberties, and the balance of power between government branches. This interpretive role reinforces the judiciary's independence and authority, enabling it to act as a crucial check on legislative and executive actions, thus safeguarding democratic integrity.
