Answer:
Interpreting laws.
Step-by-step explanation:
The judicial branch of the federal government consists of the Supreme Court. This court was given the power of judicial review thanks to the Supreme Court case Marbury vs. Madison (1803). Judicial review is the concept that the Supreme Court is responsible for interpreting what the law means. This is still true today, as the Supreme Court's main responsibility is to interpret what the US Constitution means and what rights are protected by it.
