A First Information Report (FIR) is the initial report of a cognizable offense recorded by the police. Legally, it is generally considered corroborative evidence rather than substantive evidence. It is used to corroborate the testimony of the informant or to contradict it under the Qanun-e-Shahadat Order. It does not constitute proof of the facts stated therein but serves as a vital starting point for the criminal investigation process.

Section 167 of the Code of Criminal Procedure (CrPC) provides the legal framework for the remand of an accused person to police or judicial custody when an investigation cannot be completed within twenty-four hours.

Section 59 of the Code of Criminal Procedure provides the legal framework under which a private person may arrest any individual who commits a non-bailable and cognizable offense in their presence.

An inquiry under Cr.P.C. section 4(k) is a formal investigation conducted by a magistrate to determine if there is sufficient evidence to proceed with a criminal prosecution.

Exhumation is the process of digging up a buried body for the purpose of a fresh medical examination.

Section 492 of the Criminal Procedure Code (Cr.P.C.) empowers the Provincial Government to appoint a Public Prosecutor for conducting prosecutions on behalf of the state in any court.

Section 88 of the Code of Criminal Procedure, 1898, provides the legal framework for the attachment of property of a person who has been proclaimed as an offender under Section 87. The court may order the attachment of any property, movable or immovable, belonging to the proclaimed person to compel their appearance.

Under Section 510-A of the Cr.P.C., the evidence of a public servant may be given by affidavit. However, this provision explicitly excludes the High Court from the scope of courts where such affidavits can be submitted as evidence, requiring the personal presence or other formal modes of testimony instead.
