Gun manufacturers in California may become susceptible to lawsuits from private citizens alleging negligence under a new law signed by Gov. Gavin Newsom on Tuesday.

The legislation could allow gun makers to be sued by citizens, local governments, or the state’s attorney general if one of their firearms is used irresponsibly or causes harm. It would also create a code of conduct to reduce gun violence that would “establish, implement, and enforce reasonable controls … pertaining to unfair methods of competition, unfair or deceptive acts or practices, and false advertising,” according to the bill.
