The government’s long-awaited response, to its consultation on marriage according to the usages of belief organisations, was published this week. A “belief organisation” is:-
An organisation whose principal or sole purpose is the advancement of a system of non-religious beliefs which relate to morality or ethics.
The response was to defer any legislation, and to refer the matter to the Law Commission for a broader review of the law concerning marriage ceremonies.
