**Core Concept**
In forensic medicine, a police inquest is an investigation into the cause of death or circumstances surrounding a suspicious or unnatural death. This inquiry is typically conducted by law enforcement agencies in collaboration with medical professionals. The purpose of a police inquest is to determine the cause of death and identify any potential foul play or negligence.

**Why the Correct Answer is Right**
A police inquest is not required when the cause of death is known and there is no suspicion of foul play. In such cases, a post-mortem examination may be conducted by a medical professional to confirm the cause of death, but a police inquest is not necessary. This is because the cause of death is already established, and there is no need for a formal investigation.
