A Los Angeles County Superior Court judge delivered a split decision Wednesday in a lawsuit seeking to halt the fast-tracked proliferation of wireless infrastructure without environmental review and without residents’ right to appeal.

In his ruling, Judge James C. Chalfant dismissed claims that the ordinances violate due process rights by preventing residents from contesting individual wireless project permits near their homes. He also dismissed a minor claim about a bureaucratic procedure.

However, he allowed pivotal allegations that the county is illegally sidestepping state environmental law through its new rules for approving wireless infrastructure projects.
