The U.S. Chamber of Commerce is throwing its weight behind an effort to curtail class-action lawsuits.

The business group has endorsed passage of S. 1712, “The Class Action Fairness Act,” which has bipartisan support. “The rise of frivolous class action cases over the past decade has resulted in higher prices for consumers, lower stock values for investors and an uncertain future for businesses and employees,” said James M. Wootton, president of the Chamber’s Institute for Legal Reform.
