Copsey v WWB Devon Clays Ltd [2005] EWCA Civ 932; [2005] IRLR 811 is a UK employment discrimination law case, concerning the right to freedom of religion under Article 9 of the European Convention on Human Rights.
Although changes to the timetable were approved by most other workers in the plant, in consultation Mr Copsey was not happy, and he raised objection with four others.
He then said that the change, to make him work Sundays breached his fundamental human right to freedom of religion, as a Christian.
Mummery LJ in the Court of Appeal held that interference with this right was justified in the pursuit of a legitimate aim (to run an effective business).
He was not dismissed because he was a Christian believer, but simply because his religious requirements were not compatible with the job.
