15 cases related to unreported or unregistered lobbying tagged by the city’s Board of Ethics are up for discussion at its monthly meeting this afternoon. Last month, the Board identified probable cause in 13 cases stemming from the release of Mayor Rahm Emanuel’s personal emails, and said potential fines for violations were “very significant.” Those emails, released after FOIA-related lawsuits from the Better Government Association and the Chicago Tribune, revealed more than two dozen likely cases of improper lobbying.
