The judicial branch of government is charged with ensuring that civil liberties are preserved by accurately interpreting the constitutionality of laws.

Explanation:

The American judicial branch is headed by the US Supreme Court. The Court decides at first instance in a few rare cases: cases involving one of the States of the Union, a State or a foreign diplomat. For all other matters, it has no power. In all cases, its judgments are final. It generally confines itself to the most important matters, and in particular, to decide whether the laws of the United States or those of the various states, are in conformity with the Constitution, of which it is the ultimate interpreter.  

This power of judicial review, which is the essence of the power of the Supreme Court, is not explicit in the Constitution, and the Court actually assigned it to itself in 1803 in Marbury v. Madison.
