New Mexico Gov. Susana Martinez is urging the U.S. Supreme Court to overturn a ruling allowing public-sector unions to collect fees from employees who decide not to become union members.
The Albuquerque Journal reports that Martinez argued in an 18-page brief that the fees violate employees' free-speech rights.
The Republican governor has clashed with labor unions since her election in 2010. She recently backed legislation that sought to block unions from collecting so-called "fair-share" fees, but it died in New Mexico's Democrat-controlled Senate.
The Supreme Court case involves several California teachers who object to having to pay union fees.
Labor unions argue that the fees are fair because nonunion employees benefit from union-negotiated contracts.
