The State Coroner is on call 24/7. He is contactable through the State Coroner's official handphone. He performs "Field Coroner" duties as and when he is called to perform duties outside the Court and office setting.

The State Coroner's consent is required before any organ harvesting is done on deceased persons who are made Coroner's cases, whether under the HOTA or MTERA. The organ transplant co-ordinator and the respective Investigating Officer communicate with the State Coroner and keep him informed of the circumstances of the case. Once the State Coroner is satisfied that the organ harvesting may go ahead, he gives his consent. As organ transplants are time-sensitive, the State Coroner may get calls relating to organ transplants at any time of the day or night.

Another aspect of Field Coroner duties carried out by the State Coroner is the attendance at suspected "scenes of crime". This would involve instances where a dead body is found and police suspect that there might be foul play involved in the death. Again, the State Coroner might be activated at any time of day or night for such cases. His presence at the scene is to ensure that investigations and the initial examination by the Forensic Pathologist are carried out. After preliminary investigations and the examination are done, the State Coroner gives his consent for the body to be moved to the Mortuary, where an Autopsy will subsequently be performed.

Another judicial officer is rostered, on a monthly basis, to perform field coroner duties at the Mortuary at the CFM. The officer rostered attends at the Mortuary every morning (Saturdays, Sundays and Public Holidays included). The officer's duties are to view the bodies of the deceased persons and decide if an Autopsy is required to determine the cause of death for each case. The officer ensures that bodies of deceased persons are correctly identified by the respective NOKs. The officer also determines if an Autopsy is required in each case, based on input given by the Forensic Pathologist. The officer will then decide whether an Autopsy is required for the deceased person, or whether the body may be released to the NOK without the need for an Autopsy.
