Ashers bakery has been told it may be able to take its fight against a discrimination ruling to the UK Supreme Court. The Christian-owned bakery was ruled to have broken discrimination laws by refusing to make a cake with a slogan supporting gay marriage. It appealed the verdict but the Court of Appeal rejected it. The Christian Institute, which is supporting the McArthur family who own Ashers bakery, said in a hearing on Tuesday that it could potentially launch another appeal in the Supreme Court through what the Institute called ‘a little known legal provision’. The Court has asked the McArthur family's lawyers to provide written submissions ‘probably within the next week’, according to the Institute. At Tuesday's hearing it was also said that the Attorney General, who intervened in their earlier case at the Court of Appeal, was seeking to refer the Ashers’ case to the Supreme Court ‘on devolution issues’.
