State Rep. John Lesch is not protected by "legislative immunity" in a defamation case brought against him by St. Paul city attorney Lyndsey Olson, the Minnesota Court of Appeals ruled Monday.
The decision allows Olson's case to proceed.
Olson sued Lesch last year after he sent a letter to incoming St. Paul Mayor Melvin Carter criticizing her work history and judgment, saying she has a "track record of integrity questions and management problems."
Lesch, a Democrat who represents part of St. Paul, has sought to dismiss the suit, arguing in part that he has legislative immunity. He will file a petition in the next month with the Minnesota Supreme Court, his attorney Marshall Tanick said.
"The Appellate Court construed the legislative immunity of legislators extremely narrowly, and we think that it's more proper to take a broader view of what legislators do," Tanick said.
He said he hopes the Supreme Court decides to take up the case to provide "clarification and guidance" on legislative immunity.
The Court of Appeals opinion focused on whether Lesch's letter constitutes legitimate legislative activity that should warrant immunity. They affirmed a Hennepin County District Judge's ruling that it was not.
Lesch had argued the letter was intended to get information that would help him work with the city.
