I mean, that isn’t some kind of bad thing. Appeals courts are there to catch bad prosecution. They’re supposed to protect citizens from the system failing to work as intended.
Now, the fact that it’s a rich fuck that can afford attorneys to do the work to make the appeal happen and most people couldn’t sucks. That’s a major flaw of the system, that throwing money at it means you’re gong to end up with unbalanced outcomes, but unless the decision handed down was not based in fact, a successful appeal is a good thing.
Fuck Weinstein, but this isn’t about him in specific.
