The book Radium Girls tells a true story that happened about 100 years ago. At one point in the book, a lawyer is representing about five victims (former employees) who are suing the US Radium Corporation for poisoning them. USRC offers a settlement, which includes a stipulation that the lawyer in the case must sign an agreement to not take up any additional cases against USRC (from anyone) or to provide any kind of assistance to any similar cases, ever again. The lawyer agrees to the settlement because he believes that the victims will not live long enough to take the case to trial.
This seems to me to be a ridiculous thing to ask a lawyer to agree to. If a lawyer can just agree to never represent anyone against a company, couldn’t the company just bribe every lawyer in town to sign a similar agreement, effectively making them above the law?
Was this really legal 100 years ago? Would it still be legal now?
If it matters, the book takes place mainly in New Jersey.
