A class action by Mexican “braceros” — laborers who legally came to the United States under 1940s-era guest worker programs — required some heavy lifting by the plaintiffs’ lawyers.

After eight years of heavily defended litigation that required the plaintiffs to win reversal of three trial-court dismissals, the plaintiffs claimed victory in a financial settlement paying the equivalent of $3,500 to each worker or his family. Plaintiffs’ lawyers expected settlement checks to arrive by late September.
