MADISON, Wis. (AP) -- A Wisconsin appeals court says a state senator must turn over the names of people who sent him emails during the bitter debate over Republican Gov. Scott Walker's union restrictions to a conservative think tank.
The John K. MacIver Institute for Public Policy asked Democratic Sen. Jon Erpenbach for the emails in March 2011.
Erpenbach released the emails but redacted information that identified the senders, arguing he was protecting them from possible reprisals.
The 2nd District Court of Appeals ruled Wednesday that nothing shows why Erpenbach should be given more deference in his decisions than other record custodians and public awareness of who is influencing government is crucial.
Erpenbach issued a statement saying he is weighing whether to take the case to the state Supreme Court.
