Section 337 of the Pakistan Penal Code classifies Shajjah (injuries to the head or face) into six distinct categories based on the severity and nature of the wound, ranging from Shajjah-i-Khafifah to Shajjah-i-Hashimah.

In legal and technical contexts, a corrosive substance is defined as a material that causes chemical damage or 'fretting' to surfaces, tissues, or materials upon contact. This definition is critical in criminal law regarding acid attacks and hazardous material handling, where the destructive chemical nature of the substance is a key element of the offense.

Hanging is a classic example of asphyxial death. It involves the suspension of the body by a ligature around the neck, which causes constriction. This pressure leads to the occlusion of the airway and the carotid arteries, preventing oxygenated blood from reaching the brain. Forensic experts classify it as asphyxial because the primary physiological failure resulting in death is the lack of oxygen to the central nervous system.

According to Section 82 of the Pakistan Penal Code, nothing is an offence which is done by a child under seven years of age. This provision is based on the principle of doli incapax, which presumes that a child under this age lacks the necessary mental capacity to form criminal intent or understand the nature and consequences of their actions.

Section 268 of the Pakistan Penal Code defines a public nuisance as an act or illegal omission which causes any common injury, danger, or annoyance to the public or to the people in general who dwell or occupy property in the vicinity.

According to Section 337-A of the Pakistan Penal Code, shajjah-i-damighah involves an injury to the head that reaches the brain.

Isqat-i-Haml refers to the act of causing a woman with child to miscarry, provided the fetus has not developed to the stage where it is considered a human being (Isqat-i-Janin). This is a specific offense under the Pakistan Penal Code, distinct from cases involving a fully formed fetus.

Under the Pakistan Penal Code, Isqat-i-Haml refers to the act of causing a miscarriage of a fetus that has not yet reached the stage of organ formation. This is distinct from Isqat-i-Janin, which involves a fetus that has developed organs. The law criminalizes this act unless it is performed in good faith by a medical professional to save the life of the mother or provide necessary treatment.

Suffocation is a form of asphyxial death. It occurs when the external air supply is cut off, preventing oxygen from reaching the lungs. This can happen through various means, such as obstruction of the nose and mouth or environmental oxygen depletion. Forensic pathologists classify it under asphyxia because the primary mechanism of death is the cessation of respiration and the resulting oxygen starvation of the brain and heart.

Under Section 390 of the Pakistan Penal Code, robbery is defined as theft where the offender voluntarily causes or attempts to cause death, hurt, or wrongful restraint to any person in order to commit the theft. Since A restrained Z to facilitate the theft, the act constitutes robbery.
