The Ninth Circuit decided to withdraw the opinion, here. Instead, the court certified three questions to the California Supreme Court:
First, does the California Labor Code apply to overtime work performed in California for a California-based employer by out-of-state plaintiffs in the circumstances of this case, such that overtime pay is required for work in excess of eight hours per day or in excess of forty hours per week?
Second, does § 17200 apply to the overtime work described in question one?
Third, does § 17200 apply to overtime work performed outside California for a California-based employer by out-of-state plaintiffs in the circumstances of this case if the employer failed to comply with the overtime provisions of the FLSA
So, the California Supreme Court, if it accepts the Ninth Circuit's invitation, will give its input and then the Ninth Circuit presumably will re-issue its opinion with the benefit of California's high court's analysis. Stay tuned.
