This is the case of Mr G Conisbee v Crossley Farms Limited and others on the issue, at preliminary hearing on 17th May 2019, of whether vegetarianism could be regarded as a belief.
Mr Conisbee alleged discrimination on the ground of religion or belief contrary to the Equality Act 2010, his belief being vegetarianism. At a preliminary hearing, an employment tribunal held that this belief did not qualify for protection under the Equality Act 2010. In particular, the employment tribunal concluded that the belief must have a similar status or cogency to religious beliefs and, having a belief relating to an important aspect of human life or behaviour, is not enough in itself for it to have a similar status or cogency to a religious belief.
