San Francisco City Attorney Dennis Herrera announced last week he was taking the dramatic step of suing the city’s own school district, which has kept its classrooms closed nearly a year. In the motion filed Thursday in San Francisco Superior Court, Herrera included alarming testimony from hospitals in the San Francisco Bay Area, doctors and parents on the emotional and mental harms of extended distance learning.

Circuit Court of Appeals said state courts are the proper forum for the lawsuits alleging that Big Oil promoted petroleum as environmentally responsible when producers knew it was causing damage. (AP Photo/Paul Sakuma, File)LOS ANGELES Big Oil lost a pair of court battles Tuesday that could lead to trials in lawsuits by California cities and counties seeking damages for the impact of climate change. The oil companies strategy is to keep the light from shining on their own behavior.
