The U.S. Supreme Court will let stand a Berkeley, Calif., ordinance requiring retailers to notify customers of possible radiation hazards from cell phones despite a legal challenge from the wireless communications industry association CTIA.

The court on Monday rejected CTIA's appeal of a lower court ruling upholding the ordinance, the San Francisco Chronicle reported. The association objected to the city policy on free speech grounds, arguing there is little evidence to support the assertion that cell phone radiation leads to negative health effects.

The Berkeley ordinance requires retailers to notify customers that cell phone radiation exposure may exceed federal guidelines. CTIA has previously successfully challenged a San Francisco ordinance requiring retailers to provide fact sheets noting the World Health Organization considers cell emissions a "possible carcinogen." However, the Berkeley ordinance was more modest, tying the information provided to customers to existing Federal Communications Commission standards, the newspaper reported.

CTIA told the Chronicle it was disappointed in the Supreme Court's decision as "no scientific evidence establishes a causal link" between cell phone use and poor health. https://bit.ly/36hCN2I
