Involvement in the Mayoral campaign of Bob Brady

Cozen O'Connor filed a lawsuit in the Philadelphia County Court of Common Pleas against the Philadelphia Board of Ethics in an attempt to lift campaign contribution limits for the 2007 Philadelphia mayoral election. The firm had represented Bob Brady in his efforts off a ballot challenge from Tom Knox, and wanted to be paid for its work. City law limited campaign contributions to $2,500 for individuals and $10,000 for law firms, political action committees and unincorporated businesses. In February 2011, the court ruled that the firm has the standing to challenge the ethics board. In reversing the lower courts, Justice Max Baer said Cozen O'Connor sufficiently pleaded in its declaratory judgment action its own inability to forgive the total debt without violating campaign finance laws. ^[11]
