The jury was never informed that the fact appellant was under the influence of alcohol was insufficient in itself to support a finding of gross negligence. The question of whether gross negligence existed was a complicated one and difficult to resolve. The jury was entitled to know what could not be considered on this point. (See People v. Hebert (1964) 228 Cal.App.2d 514, 519-520 [the jury was entitled to a clear statement on the doctrine of proximate cause].)

" 'It is settled that in criminal cases, even when not requested, the court must instruct on the general principles of law relevant to the issues raised by the evidence.
