From Reason:

The new law allows a long list of people to seek an “extreme risk protection order” that bars the respondent from possessing firearms. Potential petitioners include police officers, prosecutors, blood relatives, in-laws, current and former spouses, current and former housemates, current and former girlfriends or boyfriends, people who have produced a child with the respondent, and school administrators or their designees, such as teachers, coaches, and guidance counselors. The “school personnel” covered by the law can even report a former student if he graduated within the previous six months.
