jasjas you have very helpfully characterised what I am pulling you up on. You and others are implying that the Court of Session, as the Scottish Supreme court, will be "bowing" to some supranational / English legal system, by referring to the UK Supreme Court. This is NOT the case. Scotland is part of the UK and the UK Supreme Court is thus part of the Scottish Legal system.
Under the characterisations drawn by you and others it would be pretty odd for Scottish courts to have any locus at all over Westminster. If Scotland ever becomes independent this will indeed be the case. Another instance of careful what you wish for.
For anyone still struggling:
www.supremecourt.uk/about/uk-judicial-system.html
"For historical reasons, as a state made up of several separate jurisdictions, the United Kingdom does not have a single unified legal system.
Instead, there is one system for England and Wales, another for Scotland, and a third for Northern Ireland.
In most cases, The Supreme Court sits above all of these as the final court of appeal."
Just to clarify further, the legal systems have always been separate. The separation and intersections are NOT part of the Devolution settlement.
(Sorry for the massive "personsplaining" but you did ask repeatedly)
