SAN FRANCISCO — The city of San Francisco isn’t going away quietly on the issue of cellphone radiation.

Following a lengthy oral argument in which one of the judges posited that the case could be ticketed for the Supreme Court, city lawyers were stunned when the U.S. Court of Appeals for the Ninth Circuit issued a two-page unpublished ruling in September wiping out their case. On Friday, the city filed a combative petition for rehearing, imploring the full court “to give this important constitutional issue the treatment it deserves, to give San Francisco’s democratically elected policymakers the respect they deserve, and to provide jurisdictions in the circuit with the guidance they deserve.”
