THE British government’s most senior lawyers began a Supreme Court challenge today over two Bills passed by the Scottish Parliament. 

In March, Holyrood unanimously passed the United Nations Convention on the Rights of the Child (Incorporation) (Scotland) Bill, which would incorporate a UN treaty into Scottish law.

But Westminster’s Scottish Secretary, Tory MP Alister Jack, raised concerns the legislation could potentially put legal duties on UK ministers, something beyond the remit of Scotland’s devolved powers.
