(March 10, 2016, 10:26 AM EST) -- PORTLAND, Ore. — Two trial courts in two cases over tip pooling erred when the courts ruled in favor of the employers as the courts must follow the guidance of a new rule announced by U.S. Department of Labor (DOL) in 2011 rather than the precedent set by the Ninth Circuit U.S. Court of Appeals in a 2010 decision, a divided Ninth Circuit panel ruled Feb. 23 (Oregon Restaurant and Lodging Association, et al. v. Thomas Perez, et al., No. 13-35765, Joseph Cesarz, et al. v. Wynn Las Vegas, LLC, et al., No. No. 14-15243, 9th Cir.; 2016 U.S. App. LEXIS 3119)....
