What is the main role of the Foreign Intelligence Surveillance Act (FISA) Court?

The main role of the Foreign Intelligence Surveillance Act (FISA) Court is to approve applications for electronic surveillance. This court is specifically designed to conduct oversight and review applications made by the government to monitor individuals suspected of involvement in espionage or terrorism.

The FISA Court's primary function is to ensure compliance with the law while balancing national security interests and individuals' privacy rights. It reviews requests from government agencies, such as the FBI or NSA, and determines whether there is sufficient legal justification to proceed with surveillance that would otherwise require a warrant. By doing this, the FISA Court helps maintain checks on government power and protects citizens' rights as outlined in the Fourth Amendment, which guards against unreasonable searches and seizures.

The other options do not accurately reflect the functions of the FISA Court. It does not provide legal representation for foreign agents or oversee federal law enforcement operations in a general capacity. Additionally, while issues of civil rights may arise in broader discussions about surveillance practices, the FISA Court itself is not tasked with investigating civil rights violations.
