British courts already were involved.
Article 50 will be triggered on March 29.
If this was the US, you can bet your sweet bippy some activist federal judge would have blocked it by now.
Hmm, then I can only surmise that they don't have the broad latitude to single handedly block things. We could learn a lot from the UK in this regard.
It was the British supreme court, so I would think they do have a fair amount of clout. All they had ruled was that the Parliament had to approve of it, so not that big a deal.
