Jon P. Wilcox

Jon P. Wilcox (born September 5, 1936) is an American lawyer and retired judge.

He was valedictorian of his graduating class at Wild Rose High School in 1954, then attended Ripon College.

After obtaining his bachelor's degree in 1958, he joined the United States Army and was commissioned as an officer in a military police company.

In 1961, Wilcox left the Army and entered law school at the University of Wisconsin, ultimately obtaining his law degree in 1965.

Wilcox began in private law practice at the La Crosse, Wisconsin, firm of Steele, Smyth, Klos & Flynn.

Wilcox would later refer to Jerry Klos as his mentor.

After a few years in La Crosse, Wilcox and his wife purchased 2500 acres of farmland near Wautoma and relocated there.

In 1968, he formed his own law partnership, Wilcox, Rudolph, Kubasta & Rathjen.

Also in 1968, Wilcox was approached to run for the Green Lake and Waushara seat in the Wisconsin State Assembly.

He recognized politics as a good way to advance his law career, and decided to enter the race.

He soundly defeated Republican primary opponents Scott P. Anger and Clifford D. Bvocik, then went on to win the general election without opposition.

In the Assembly, Wilcox would serve on the committees for elections, taxation, the judiciary, and insurance and banking, and served on a joint advisory committee on automobile accident liability.

He served on the Governor's commissions on reapportionment and highway safety, and served on a special legislative committee on criminal penalties.

He ultimately served three terms in the Assembly, having been re-elected in 1970 and 1972.

He did not seek re-election in 1974, facing pressure from his law partners to devote more time to the firm.

Though he left the legislature, Wilcox remained involved in politics.

He served as Chairman of the Waushara County Republican Party from 1975 through 1979, and was the state co-chair of Ronald Reagan's 1976 presidential campaign.

He was also an elected member of the Wisconsin Conservation Congress from 1975 to 1980.

Schreiber had appointed James Poole to the Waushara Circuit Court judgeship in 1978 after the death of Judge Boyd A. Clark, but Poole died unexpectedly on the day he filed to run for a full term in 1979.

An aide to Schreiber asked Wilcox to consider running for the seat.

Wilcox ultimately returned to public office in 1979 at the behest of Governor Martin J. Schreiber.

Wilcox eventually decided to pursue election as a write-in candidate and was victorious in the April 1979 election.

He would go on to be re-elected without opposition in 1985 and 1991.

Due to its small population, Wilcox was the only judge for Waushara County.

He saw every state case in the county, for situations ranging from criminal prosecution to property or liability disputes.

In 1985, the Wisconsin Supreme Court appointed Wilcox Chief Judge of the 6th Administrative District of Wisconsin Circuit Courts, comprising, at the time, the counties of Adams, Clark, Columbia, Dodge, Green Lake, Juneau, Marquette, Portage, Sauk, Waushara, and Wood.

As chief judge, he was empowered to assign judges, oversee the caseflow, and supervise the personnel and budget of the courts within his administrative district.

Wilcox served three two-year terms as chief judge, which at the time was the statutory maximum for consecutive terms.

He served as chairman of the Wisconsin Sentencing Commission from 1987 to 1992.

During his later years on the court, he also served as a faculty member of the Wisconsin Judicial College.

He was elected chairman of the Wisconsin Chief Judges Committee in 1990.

He was a justice of the Wisconsin Supreme Court for 15 years, appointed by Governor Tommy G. Thompson in 1992 and leaving office in 2007.

In May, 1992, Wisconsin Supreme Court Justice William G. Callow announced that he would resign, effective September 1.

Wisconsin Governor Tommy Thompson selected Wilcox to fill the vacancy, and he was sworn in on October 7, 1992.

The appointment would allow Wilcox to fill out the remainder of Callow's ten-year term, expiring in 1997.

Prior to his time on the Supreme Court, he served for 13 years as a Wisconsin Circuit Court Judge, including seven years as Chief Judge of the 6th Judicial Administrative District of Wisconsin Circuit Courts.

Earlier, he represented Green Lake and Waushara counties in the Wisconsin State Assembly as a Republican.

In the Fall of 2023, Wilcox was one of three former Wisconsin Supreme Court justices who advised Assembly speaker Robin Vos on the question of whether to impeach new justice Janet Protasiewicz.

Wilcox released his opinion to the press on October 11, 2023, saying that he "did not see that there were any impeachable offenses."

Wilcox was born at hospital in Berlin, Wisconsin, and grew up in nearby Wild Rose.
