is intending to cause someone to be bed bound GBH?Watch this thread
So if you spread Covid 19 by your inactions (not wearing a face covering for example), and someone dies, could you be charged with manslaughter?
There are two broad categories of manslaughter: (1) where the defendant (D) intended to kill or cause GBH, but has available to him one of the partial defences to murder, such as diminished responsibility; and (2) "involuntary manslaughter", where D does not intend to kill or cause GBH, but the victim (V) dies anyway as a consequence of D's act. Involuntary manslaughter then takes two forms: unlawful act manslaughter; and gross negligence manslaughter. In the scenario you describe, we would be dealing with involuntary manslaughter.
Applying then each of the two types of involuntary manslaughter in turn. Unlawful act manslaughter arises where D causes someone's death as a result of some unlawful act. Sounds obvious, but you have to establish that an unlawful act has actually occurred. In this case, you would need to show D, without reasonable excuse, breached the regulations mandating the wearing of face masks in certain places, and on public transport (which is a criminal offence, provided it falls within the scope of the Regs). You would then need to show that that unlawful act was objectively dangerous. Both of those things (i.e. the breach of the Regs, and the objective dangerousness) are not easy to establish, particularly given the breadth of possible "reasonable excuses" available as a defence to a breach of the Regs.
You're then left with gross negligence manslaughter. Again this is a complicated area, but put shortly, you would need to show D breached an existing duty of care to V, in circumstances where it was reasonably foreseeable that D's breach would give rise to a serious and obvious risk of death, and where D's conduct was so bad in all the circumstances as to amount to a criminal act. This is a very high hurdle. By way of relevant example, you may have seen the press coverage of the awful case where someone spat at a TFL train worker, and she subsequently died of Covid-19. It is common sense that spitting on someone in the middle of a global pandemic is more serious than simply not wearing a mask, but even in these circumstances, the police did not have sufficient evidence to charge anyone. I think this was largely an issue of causation (i.e. establishing that the victim's death was a result of being spat at), but it demonstrates the practical difficulties with bringing cases of this kind.
TL;DR: almost certainly not.
