When I first read about the case (when she was initially convicted) I did have mixed feeling about whether conviction for manslaughter was the right decision.
I finally came to the conclusion that, although slightly unfortunate and unforeseeable for the Defendant, the court must have found that Ms Gray's act of shouting and waving her arms must have amount to some level of assault.
(Bare in mind assault doesn't necessarily have to occasion any physical touch, just that a person is put in immediate fear of danger - the CCTV does not actually show whether there was physical contact or not - and if not, would waving your arms and pointing amount to such a wholly "dangerous"/unlawful act worthy of a conviction for manslaughter? )
Then I heard about the conviction being quashed yesterday, and it seems that the principle error here was in the gross assumption that the Defendant did assault her without properly examining the evidence.
You must understand that to be convicted of dangerous/unlawful act manslaughter, there should be a proper examination into whether the
principle offence has been committed (in this case, the underpinning offence would be to prove there was an assault first).
It was observed that had the cyclist not have been hit by the car and lived, then the cyclist herself would probably not have reported the incident as an assault.
I actually think, given this fundamental lack of examination of this particular element of the case, that quashing the conviction was the right outcome.
