Interesting. Define "legitimate".
Latham is primarily a business firm. They do both litigation and transactional work. We can agree that in litigation our notions of due process requires that all those who “interact” with our court system are entitled to counsel of their choice and a fair trial. So they represent despicable characters or entities. When I was in practice, so did I. That is part of the ethical obligations of lawyers.
I’ve never done transactional work, and have only had one very big case arising out of a failed “transaction” - funding of a very large complex. Transactional work can range from bond offerings to IPO’s and the like.
It’s all “legitimate”.
Latham is a huge firm - many thousand lawyers, all over the world. I could never afford them, but if I could, I’d hire them in a heart beat.
