Cohen Milstein Sellers & Toll, a plaintiffs firm that has a track record of partnering with public sector clients, earned $5.4 million for its work on behalf of Chicago in a suit looking to collect higher taxes from Expedia Inc.

The fees for Cohen Milstein, whose partner Carol Gilden served as outside counsel for the city of Chicago, come in connection with an $18 million settlement that Expedia and two subsidiaries—Hotwire and Hotels.com—paid to resolve tax-related litigation in Illinois’ Cook County Circuit Court. Sidley Austin represented Expedia in the case.
