Paul J. Watford

Watford authored the decision of the Ninth Circuit's en banc decision in City of Los Angeles v. Patel (2014). In that case, the court struck down, 7–4, a Los Angeles city ordinance authorizing police to conduct surprise inspections of hotel and motel guest registries without obtaining the owners' consent or a search warrant. Watford, writing for the court, held that the ordinance violated the Fourth Amendment. The following year, the U.S. Supreme Court affirmed the decision in a 5–4 vote.

In late 2012, multiple national news organizations mentioned Watford as a possible nominee to the Supreme Court of the United States during Barack Obama's second term.

On October 17, 2011, President Obama nominated Watford to a seat on the United States Court of Appeals for the Ninth Circuit. The seat had been vacated by Judge Pamela Ann Rymer, who had occupied the seat from 1989 until her death from cancer on September 21, 2011. The ABA Standing Committee on the Federal Judiciary unanimously rated Watford as a "well-qualified" nominee, the highest possible rating. The Senate Judiciary Committee held a hearing on Watford's nomination on December 13, 2011. On February 2, 2012, the Judiciary Committee reported Watford's nomination to the floor of the Senate by a vote of ten ayes to six nays. At the hearing, Senator Patrick Leahy noted that Watford had support "from across the political spectrum," including support from a number of prominent conservative legal figures, including Orin Kerr and Eugene Volokh. On May 17, 2012, Senate Majority Leader Harry Reid filed a cloture motion on Watford's nomination, seeking to end debate on the nomination. The vote on the cloture motion had been scheduled for May 21, 2012. However, on May 21, Reid asked that the cloture motion be nullified, and that the Senate move to a straight, up-or-down vote on Watford's nomination, which was scheduled for later that day. The Senate confirmed Watford on May 21, 2012 in a 61–34 vote; he received his commission on May 22, 2012.

Watford is an active member of the American Bar Association, serving as Co-Chair of the ABA Litigation Section's Appellate Practice Committee from 2005 to 2008 and as a member of the ABA's Amicus Curiae Committee from 2007 to 2010. From 2007 to 2009, he taught an upper-level course in judicial opinion writing at the University of Southern California's Gould School of Law. Since June 2012, he has served as treasurer and board member of Neighborhood Legal Services of Los Angeles County, a nonprofit providing pro bono legal services to the poor.

In 1994 he served as a law clerk to Judge Alex Kozinski of the Ninth Circuit, and from 1995 to 1996 he clerked for Justice Ruth Bader Ginsburg of the Supreme Court of the United States. In 1996 he joined the law firm Munger, Tolles & Olson. In 1997 Watford became an Assistant United States Attorney in the Major Frauds Section of the Criminal Division of the Central District of California, where he prosecuted a wide range of federal criminal cases, including white-collar criminal cases. In 2000 he joined the Los Angeles office of the Chicago-based law firm Sidley Austin, but he returned to Munger in 2001, where he became partner in 2003. At Munger, where he worked until his confirmation, he focused on appellate litigation, appearing regularly in state and federal courts to argue his cases. He has authored or edited nearly twenty briefs prepared for the Supreme Court.

Watford was born in Garden Grove in Orange County, California and graduated from Laguna Beach High School in 1985. He received a Bachelor of Arts in 1989, from the University of California, Berkeley, and a Juris Doctor in 1994 from the University of California, Los Angeles, Order of the Coif.
