MADISON (WRN) - A second lawsuit has been filed against Wisconsin’s “Impartial Justice” law – which seeks to limit special interest money in Supreme Court campaigns. Wisconsin Right to Life filed the first lawsuit earlier this month in federal court. The new one comes from Jefferson County Circuit Judge Randy Koschnick, who lost in last April’s Supreme Court contest to Chief Justice Shirley Abrahamson. Both suits say the new law violates free speech rights guaranteed in the 1st Amendment. Under the law, Supreme Court candidates can get $100,000 for a primary contest, and $300,000 for a general election. They also get extra funding to answer charges made against them in ads by special interest groups. Koschnick’s lawsuit says the additional funding will discourage special interests from speaking out in the first place – thus limiting their free speech rights. His suit is funded by the Center for Competitive Politics in Virginia. The law was passed in response to millions in special interest money spent in the last 3 Supreme Court elections. The next contest is in the spring of 2011, when Justice David Prosser is up for another 10 year term.
