Lawsuits are a tough sell when a plaintiff has specifically agreed to not sue the defendant.
Take NASCAR driver Jeremy Mayfield, for example. In May 2009, Mayfield was suspended from the NASCAR circuit after failing a random drug test. NASCAR announced the reason for the suspension, and Mayfield filed a lawsuit.
This week, the Fourth Circuit Court of Appeals ruled that Mayfield had no case because he signed two contracts waiving his right to a NASCAR lawsuit, The Associated Press reports.
