The Federal Investigation Agency was established and currently operates under the Federal Investigation Agency Act, 1974. This legislation provides the legal framework for the agency's jurisdiction, powers, and functions in investigating federal crimes, including corruption, cybercrime, and human trafficking across Pakistan.

The Federal Investigation Agency Act, 1974, is a federal law that applies to all citizens of Pakistan who commit offences specified in the schedule of the Act. While the agency often investigates public servants or high-profile cases, its jurisdiction under the law extends to any individual involved in the commission of federal crimes as defined by the statute.

According to Section 3 of the Federal Investigation Agency Act, 1974, the Federal Government is empowered to constitute an agency known as the Federal Investigation Agency. This agency is tasked with the inquiry and investigation of specific offences listed in the Act's schedule, including any attempts, conspiracies, or abetments related to those offences.

The FIA Act empowers the Federal Government to frame rules to carry out the purposes of the Act. These rules typically encompass the terms and conditions of service for the agency's personnel, including the Director General. By allowing these conditions to be defined in the rules, the legislature provides the government with the flexibility to adjust administrative requirements as needed, while maintaining a structured and regulated framework for the appointment and service of the agency's leadership.

According to the relevant sections of the FIA Act, the power to arrest without a warrant is a significant authority granted to agency members. To ensure accountability and prevent abuse of power, this authority is restricted to members holding at least the rank of Sub-Inspector, provided they have been specifically authorized by the Director General. This requirement balances the need for effective law enforcement with the necessity of maintaining strict procedural oversight.

Section 5 of the FIA Act deals with the powers of the agency, including the ability to issue specific orders during an investigation. The Act stipulates that any person who contravenes such an order is liable to punishment. The prescribed penalty for this specific violation is imprisonment for a term that may extend to one year, or a fine, or both. This provision ensures compliance with the agency's investigative directives and maintains the integrity of the evidence-gathering process.

The superintendence of the Federal Investigation Agency is vested in the Federal Government. This ensures that the agency operates under the executive control of the state, maintaining accountability and alignment with national policy objectives regarding federal crimes and investigations.
