Whatever we as individuals think, this judgement was based on matters that are legal, but political, in tandem. You can go right back to 1611 when King James VI was challenged, as then the effective Parliament of the land, about Proroguing Parliament, and that involved legally the earlier
Case of Proclamations [1610] EWHC KB J22 which is a UK constitutional law case that has formed the backbone of the standing of the justice system and that of the King, now in 2019, the Prime Minister.
Now, 11 justices made the latest judgement, with all the highly trained legal experts, that is QC's, who have commented so far not even beginning to challenge this judgement because they, although not having heard the legal proceedings, see no reason to do so.
It is obviously avery complex legal matter that goes to the heart of our democracy, the unwritten Constitution, the law, and the standing of Parliament, with the monarch involved.
I cannot speak for all of you, but this matter is way above my head and legal knowledge!!
The judgement is what it is; the action by Boris Johnson as Prime Minister to Prorogue Parliament was unlawful. I, like you, must at this point in time accept that legal verdict by the highest court in the land
