Sometimes, lawsuits take a *long* time to get through the courts to the point where they’re dismissed or resolved. Six years from incident to dismissal doesn’t surprise me as much as I wish it did.
There’s a book called “The True Stella Awards” [stellaawards.com] by Randy Cassingham, which is full of documented court cases that waste time & money, set bad precedents, try to punish the wrong people, etc, and it’s disheartening to see how long the process can take.
