There are some Brexiteers who greeted the orignal case with acclaim when they won, and who now say this ruling is unimportant. Not the least of these is Dominic Raab, who as a lawyer should well understand this is a long process with appeal upon appeal, as I said in a post of a few days ago: it is a long game. (Apologies for not referencing the post, but my ability to look this up is hampered by a very limited Internet connection at the moment.)
