Wow that sucks. One is tempted to admire the chutzpah of GS defense lawyers, simultaneously claiming both that their contract was with a company that no longer exists and that the lawsuit was a breach of that contract by the Bakers. Now that was a shitty contract! If one requires M&A work, one must already have an experienced M&A attorney to approve the "engagement letter". To get a reference to such an attorney, one must already have spent lots of money with a different law firm that is large enough to have a partner with a clue. Good luck with that, if you've been spending all your time developing technology rather than e.g. orchestrating dodgy real estate schemes like a particular presidential candidate. The house always wins.
As a juror, I would never vote "guilty" on a drug crime. Also, I would always find for the plaintiff if GS were the defendant.
