Death by misadventure
Manos, I hope this helps to explains English law in respect of sudden deaths.
When all the evidence has been heard, the Coroner (and jury) will deliver the verdict, which will be one of the following:
a. natural causes
b. unlawful killing
d. accidental death, or death by misadventure. (Either can be used, and the former imputation of part-responsibility in 'misadventure' no longer applies.)
e. from an industrial disease
f. an open verdict, when the Coroner decides that the evidence given at the inquest is insufficient to deliver one of the specific verdicts above; however, if new evidence becomes available at any time which varies the verdict, the inquest can be re-opened.
Any of these verdicts can, in certain circumstances, be challenged. An application to do this must be made within three months.
