Who is William K. Sessions III?

William K. Sessions III is serving as judge on the United States District Court for the District of Vermont and has served as the Chair of the United States Sentencing Commission. He was confirmed on October 21, 2009 as Chair of the United States Sentencing Commission, and served until December 22, 2010.

Sessions was educated at Middlebury College where he earned a B.A. in 1969. He earned a J.D. in 1972 from The George Washington University Law School. Sessions served as a U.S. Army First Lieutenant. He was a law clerk for Judge Hilton Dier in Addison County District Court in 1973. He later worked for the Addison County Public Defender before entering private practice in 1978. He also worked as an adjunct professor at Vermont Law School from 1978 until 1995.

Sessions was nominated by Bill Clinton on June 30, 1995, to a seat vacated by Fred I. Parker. He was confirmed by the Senate on August 11, 1995, and received his commission on August 14, 1995. Sessions has served as chief judge, 2002–present.

On September 12, 2007, Judge Sessions of the federal district court in Vermont ruled in favor of the Sierra Club, the states of Vermont and New York, and other environmental groups in rejecting the auto industry’s attempt to block states from regulating global warming emissions from cars. Session’s ruling opens the doors for New York and Vermont to proceed with enacting the California Clean Car Standards, pending United States Environmental Protection Agency approval. These standards, adopted by California and at least 11 other states, aim to reduce global warming emissions from cars by 30 percent when fully implemented in 2016. This precedent will likely have an important impact on similar cases pending in California and Rhode Island.
