The Federal Investigation Agency (FIA) is tasked with investigating a wide array of federal offences. Its mandate includes, but is not limited to, organized corruption, cyber-related crimes, and money laundering. These areas are critical to national security and financial integrity, and the FIA is the primary agency responsible for enforcing laws related to these complex criminal activities.

Under the relevant provisions governing the Federal Investigation Agency (FIA), a Sub-Inspector is the minimum rank empowered to exercise the authority to arrest an individual without a warrant in specific circumstances. This power is granted to ensure that law enforcement officers can act swiftly when necessary to prevent the destruction of evidence or the escape of a suspect in cases falling under the agency's jurisdiction.

The Director General of the Federal Investigation Agency is empowered to delegate his administrative and operational authority to members of the agency to ensure the smooth functioning of the organization. This delegation is a standard administrative practice that allows the agency to maintain operational continuity and efficiency, provided that the delegation is made to qualified personnel within the agency's hierarchy as permitted by the governing statutes.

The official motto of the Federal Investigation Agency (FIA) of Pakistan is 'Truth and Honesty'. This motto reflects the agency's commitment to integrity and transparency in its investigative duties and its mandate to combat federal crimes, including corruption and cybercrime.

In the standard administrative hierarchy of the Federal Investigation Agency (FIA) and similar government departments, the rank of Director is superior to Deputy Director, Assistant Director, and Inspector. This ranking structure is essential for the chain of command, ensuring clear lines of authority, accountability, and operational oversight within the agency's administrative and investigative functions.

The Federal Investigation Agency (FIA) is empowered to investigate specific federal offences listed in the schedule of the FIA Act, 1974.

The Federal Investigation Agency (FIA) is a premier investigative agency in Pakistan with a broad mandate.

The legal powers and responsibilities of an FIA Sub-Inspector are often compared to those of a Station House Officer (SHO) within the provincial police structure. This comparison highlights the investigative and administrative authority vested in the Sub-Inspector to manage cases, conduct inquiries, and exercise police powers within the scope of the FIA's mandate, ensuring that the agency can operate effectively in its specialized investigative capacity.

Section 21 of the Control of Narcotic Substances Act, 1997, empowers officers to perform specific duties related to the enforcement of the act, such as search and seizure. The law specifies that these powers can be exercised by an officer not below the rank of Sub-Inspector. This requirement ensures that only trained and sufficiently senior law enforcement personnel are authorized to conduct sensitive operations involving narcotics investigations and arrests.

Section 4 of the Act provides a legal mechanism for the controlled cultivation of narcotic plants for legitimate purposes. It empowers both the Federal Government and, under specific authorization or delegated powers, the Provincial Governments to issue licenses. This dual-layered oversight ensures that any cultivation is strictly monitored and limited to authorized medical, scientific, or industrial applications.
