//Boris' hands look to be tied a little tighter.//
Not really. There is no need for them to threaten court action. The Prime Minister has no option but to comply with the law, however much it irks him. As much as I want to see a swift and proper Brexit, if politicians begin to pick and choose which laws they will comply with and which they won't we're at the top of a very slippery slope. It's ludicrous to suggest he will not comply.
