The coroner decides who should be called to give evidence as a witness and the order in which they give evidence but the coroner will listen to representations made by the ‘interested persons’ as to who should be called. Anyone who believes they may be of help or believes a particular witness should be called should inform the coroner. The test is whether the witness is likely to provide evidence that is relevant to the matters that the coroner has to investigate. The coroner will decide if the evidence is relevant to the investigation of the death.
