California: Dublin school board trustee forced to step down by signature campaign

Not actually a recall, but an interesting adjacent event. Niranjana "Nini" Natarajan was forced to leave the school board after 75 signatures were handed in. Natarajan was appointed to the board following the resignation of another member. However, the voters had the ability to cause of vacancy for a seat filled by an appointment if they submitted enough signatures. Because the school board switched to a district based (rather than an at-large) system, the amount of signatures needed to trigger this provision was very small.

Dublin has had recent recall threats against a school board member and other officials.
