Unpopular again: The UK is split between Leave and Remain. It may be split between those who respect the law above all else and those who don't. We should not confuse the two. Don't bet every Leaver will be equally outraged by the SC today.
The judgement of the Supreme Court is the law. The Scotland Act is law. The Scottish Government if it acts outside of these will have their actions struck out. No wildcat #indyref2. The SNP were instrumental in bringing the current action to court.
