//…the bakery owners were successfully prosecuted under the law//
//Then what was the basis for the couple successfully taking the bakers to court?//
//As I understand it, the Supreme Court reversed the original ruling - therefore there must have been an original successful court ruling for the SC to overturn - ?//
Then you misunderstand, Andy. In the UK the legal process is not complete until all avenues of appeal have been exhausted by those to whom those avenues are open. This can involve the Crown Court, the High Court or Court of Appeal (as appropriate) and the Supreme Court. Convictions and civil rulings are often overturned in the higher courts, particularly when matters of law, not made clear in the statute, are disputed.
This action was ultimately unsuccessful and any that follow with similar characteristics are likely to be equally unsuccessful as the Supreme Court ruling sets a precedent which can be cited. The idea that the action was “successful in the interim” before being finally dismissed is rather like saying a football team is successful if they are leading at half-time or at the end of a two-legged tie.
//They preferred to pronounce from their very high horse, and paid the price for their arrogant bigotry.//
But they didn’t, though, did they?
//Bednobs and strictly speaking are still not as the law was not passed by Stormont but by Westminster so there are many that claim it is not legal!//
Ah! Devolution rears its ugly head!. You must remember, Helen, that the devolved administrations are precisely that – devolved. They are not independent. They act under devolved powers from Westminster in certain agreed areas only and those powers can be modified or withdrawn. The arrangement is that the Supreme Court is the final arbiter for all civil cases in the UK and the final court of appeal for criminal cases in England, Wales and NI. Scotland has its own distinctive legal system (which existed long before devolution) and, with one or two very limited exceptions, has its own final arbiter known as the High Court of Justiciary.
