When is postmortem needed?
In a normal natural death, where a doctor can certify the cause of death and there is no suspicion, cremation can usually proceed without postmortem after the required death certificate or hospital release papers are issued.
Postmortem may be required when the death is due to accident, suicide, fall, burns, poisoning, assault, drowning, injury, unknown cause, brought-dead case with doubt, or any situation where police or hospital marks it as medico-legal. In such cases, the body is released for cremation only after postmortem and police or hospital clearance.
