There was a “changing of the guard” at the Minnesota Supreme Court on Monday. David Lillehaug was sworn in as the newest associate justice in a ceremony at the Minnesota Judicial Center. He is replacing Justice Paul Anderson, who reached the mandatory retirement age of 70 after 19 years on the high court. Lillehaug has longstanding ties to the Minnesota DFL. He was Dayton’s attorney during the governor’s race recount in 2010 and also worked for US Senator Al Franken during his 2008 election recount. The South Dakota native and Harvard Law grad served as Minnesota’s US attorney under President Bill Clinton as well. He revealed last week that he’s been diagnosed with throat cancer, and will undergo treatments for it beginning in mid-June.
