Minnesota, a state known for clean politics, ranks among the worst for financial disclosure from the judiciary, according to the Center for Public Integrity.

"Minnesota is at the back of the pack for financial disclosure requirements, ranking 45th in the country along with Iowa," the Center found in a nationwide study of disclosure required of supreme court justices. "It has a self-policing system for enforcing the disclosure rules, in which Supreme Court justices would be asked to rule on a complaint about themselves. And the state currently does not require judges to report gifts, investments such as stocks or any financial debts on the one-page form."

The Center gave Minnesota an "F," for its judicial disclosure requirements. Minnesota's low ranking on this score is not unusual -- the state often gets below average grades from good government groups that measure transparency and disclosure required of public officials.

Earlier this year the state's campaign finance agency and some lawmakers pushed for more financial disclosure from lawmakers and other public officials. While that proposal largely fell by the wayside, Minnesota did increase the disclosure required of the judiciary.

From the Center: "Minnesota is toughening its requirements starting next year, meaning its lousy grade will undoubtedly improve. Legislation passed this year will require judges to file an additional form that other state officials already file. The form will ask judges to report investments, locally owned real estate and even involvement in horse racing starting in January 2014."
