It's a civil suit brought by Trump as a private citizen and not the government, and it was dismissed in September, as your link shows. Trump is of course fighting that with an appeal, but this suit has in general not gone well for him, if you peruse through all the motions. I mean, he apparently failed to correctly pay the filing fee at first and the whole thing was almost thrown out until he ponied up the 400 bucks? That's what I, an admitted complete law novice, gathered from browsing your link.

Also, she is probably not in court. This lawsuit is still mainly in the lawyer back-and-forth stage.

Also, this suit was only brought earlier this year, so probably not what Q was referring to in 2017.
