LOL that's pretty sad as an attempt to deflect from the fact that:
A) Stewart is demonstrably a liar, who can't even agree that she lost in court, even though you admitted she did.
B) Benel agreed that he wasn't actually stolen from.
As for your questions:
C) I'm sure scripts have been stolen - there's some evidence, for example, that the concept for B5 was suggested by an executive who had seen the B5 script, to the people who made DS9 (who had no idea they were being handed a "borrowed" idea). Or better yet Gravity, which pretty 100% was stolen and what protected the studios was pushing this idea that they didn't have a contract with Tess Gerritsen and as Tess herself points out, they did technically own the copyright to her work (but they should still have paid her for it). Unlike with Stewart, Gerritsen's claims are fully supported by court documents, and was demonstrably excluded from profit on what was essentially a technicality.
Yesterday, the court granted Warner Bros’s motion to dismiss my lawsuit against them. While Warner Bros crows victory, the judge has in fact left the door open for me to pursue my claim, allowing my legal team twenty days to revise our complaint and address the single issue of concern: the corporate

D) Juries and judges are 100% irrelevant to all the examples you've presented. Stewart's case was dismissed because she didn't even turn up, not because a judge or jury made some wacky decision. Benel case had some rulings about evidence, but as I understanding it, in the end it was settled - and thus no judge or jury was involved in that settlement beyond the judge saying "Sure, okay, fine". So I'm not sure what the point you think you're making here is.
