If the prosecution is for “causing death by….”, then there is unlikely to be an inquest, even if the Defendant is acquitted. This is because the criminal court will be deemed to have investigated the death.
Occasionally the Coroner will investigate the death if there is an aspect of concern that has not been investigated by the criminal court. One such example would be if the Defendant was drunk but employed – the Coroner may have concerns as to how an employer lets a drunk employee out on the road.
For non-death prosecutions, e.g. not having insurance, there will always be an inquest.
