In this case, the Court of Appeal of California issued a decision overturning a ruling by a California state court judge that found that California statutes providing tenure protections to K–12 teachers violated the equal protection provisions of the California constitution. The case arose from a challenge, funded by anti-union organizations, to five California statutes that provide primary and secondary school teachers a two-year probationary period, stipulate procedural protections for non-probationary teachers facing termination, and emphasize teacher seniority in reductions of force. The AAUP submitted an amicus brief which argued that the challenged statutes help protect teachers from retaliation, help keep good teachers in the classroom by promoting teacher longevity and discouraging teacher turnover, and allow teachers to act in students’ interests in presenting curricular material and advocating for students within the school system. The Court of Appeal reversed the trial court’s decision, holding that the statutes themselves did not create equal protection violations, so they are not unconstitutional.
