Peter J. Barnes, Jr. (born September 12, 1928 in East Providence, Rhode Island) is an American Democratic Party politician, who has served as Chairman of the New Jersey State Parole Board since March 2007. He previously served in New Jersey's General Assembly from 1996 to 2007, where he represented the 18th legislative district. In the Assembly, he served as the Majority Whip from 2002 to 2007.
On February 5, 2007, Governor of New Jersey Jon Corzine nominated Barnes to serve as Chairman of the New Jersey State Parole Board. In mid-March, he resigned his Assembly seat to assume the Parole Board Chairmanship. On March 14, 2007, Barnes was confirmed by the New Jersey Senate and Barnes' son, Edison Councilman Peter J. Barnes III, was chosen to fill his father's vacant seat.
Before his departure, Barnes served on the Assembly Law and Public Safety Committee (Chair), the Assembly Regulatory Oversight Committee and the Human Services Committee.
During his ten plus years in the Assembly, Barnes was the primary sponsor of 62 bills that were signed into law.
He authored several major pieces of legislation, including a landmark bill that was signed into law in 2004 creating the New Jersey Commission to Review Criminal Sentencing. This research outlet is composed of key representatives of the criminal justice system, who serve without compensation, and are charged with promoting sound sentencing policy founded on the basic principles of public safety, proportionality and fairness. After conducting empirically-based research, this deliberative body is charged with making recommendations to the Legislature on appropriate amendments to the State's sentencing code.
