A few things. Firstly I am really, really, off pissed and then
Primogeniture will have been the reason why male hasn't been changed, so this shows primogeniture and class rule in Scotland (as in all the UK)
Media bias, though some might swing (the Times is your best bet) and the comments are a good place to look for the measure of support.
The Judges in the lower courts can be more 'captured'. When you get to the upper courts, they are fiercely protective of their independence (though is this the case in Scotland) and therefore the case stands a better chance.
I think you also have a problem with the SNP being for the Scots (though clearly not Scottish women) and therefore many who want to keep them in power. Not good for Scots though
