A California appeals court partially reversed a decision finding that Proposition 22 was invalid in an opinion Monday.

A panel for California’s First District Court of Appeal found that the November 2020 ballot measure that classified app-based drivers as independent contractors instead of employees does not trespass on the Legislature’s authority or violate a rule requiring ballot initiatives to only focus on one subject. However, the justices ruled that a provision of the law defining when lawmakers could amend Prop 22 without voter approval violates separation-of-power principles.
