What we can deduce from a leaked PDF
> I believe it’s much more likely that the leaker is someone who supports the opinion rather than an oppo­nent> If [the majority bloc in favor of the opinion has held together], there’s no reason for a supporter or an opponent to leak an old draft now.I don't find the reasoning behind this convincing at all. It would make for a good plot twist in a book, but in my opinion the leaker was most likely an opponent wanting to spark national outrage ahead of the final ruling, in an effort to either pressure judges if the outcome can still be changed, or as an act of vengeance against the court in retaliation for a ruling they feel extremely strongly about.
