Interesting. I have to say, that was one of the strangest rulings I'd ever seen. This makes sense:

An assistant to the judge who called for a halt to the John Doe investigation into possible illegal campaign coordination between Gov. Scott Walker's campaign and conservative groups is married to a lawyer for Walker's campaign.

Steven Biskupic, a former U.S. attorney who is representing a party in the secretive John Doe probe, indicated Thursday in an email to the State Journal that there was no conflict of interest for Judge Rudolph Randa, whose judicial assistant is Cary Biskupic, Steven Biskupic's wife.

"For the time period that my wife has worked for Judge Randa, I have not and would not appear in front of him on any matter," Steven Biskupic said. "I have not been and will not be involved in the (Eric) O’Keefe federal lawsuit. Even before the case was assigned to Judge Randa, I and my partner would not and could not participate in a lawsuit against Fran Schmitz personally."

A state appeals court ruling in the John Doe investigation, which is separate from the lawsuit brought by the Wisconsin Club for Growth against the prosecutors in federal court, established that Biskupic is representing a party in the case.

Walker's campaign paid Biskupic's law firm $86,000 last year, according to a recent campaign finance report. Walker's campaign is also one of the targets in the John Doe probe, according to court filings.
