Democratic state Sen. Mike Skindell is running for the Ohio Supreme Court this fall.
Skindell, an attorney from the Cleveland suburb of Lakewood, has been a central figure in Democrats' legal and policy battles over privatization and hydraulic fracturing in the state.
The Ohio Democratic Party's state executive committee voted on his nomination Tuesday after the party's original candidate dropped out. A party spokesman said Skindell was the only applicant to formally request the nomination. Skindell would challenge Republican Justice Terrence O'Donnell.
An outspoken critic of Gov. John Kasich, Skindell has served four terms in the Ohio House and was elected to the Ohio Senate in 2010. He also worked as an assistant to former Ohio Attorney General Anthony Celebrezze Jr.
