A judge Friday rejected challenges to California’s statewide requirement that students and staff wear face masks indoors at schools to prevent spread of COVID-19, leaving it to the governor to decide when it’s safe to lift the mandate.

The judge heard arguments earlier in the week on a lawsuit brought in July by two parent groups, Reopen California Schools and Let Them Breathe, arguing the mask requirement was not based on scientific evidence of need and that the face coverings are physically and mentally harmful to kids.
