A Pima County Superior Court judge placed political activist John Kromko on two years' supervised probation Monday for petition forgery and attempted fraudulent scheme or practice.
Judge Terry Chandler also ordered Kromko to complete 100 hours of community service.
Kromko's attorneys asked the judge to place Kromko on unsupervised probation, but she refused.
In late January Kromko admitted forging 29 names on a petition that may have qualified him to run for the Arizona House of Representatives in the 2008 general election.
Chandler said she found it troubling that Kromko later told a probation officer he believes someone forged the signatures on his behalf. The judge told Kromko that political and community activists think of him as a role model, and his actions don't set a good example.
Kromko, 70, initially faced several felony counts of identity theft, forgery and fraud that could have landed him in prison.
The forgery count is a misdemeanor, and the fraud charge is a felony, but it could be knocked down to a misdemeanor if he successfully completes his probation.
The plea agreement also states that Kromko cannot run for public office for at least five years.
Kromko served in the House from 1976 to 1990, marched with civil rights activist César Chávez and taught in high school and college.
