William W. Leathem

William is a seasoned litigator whose law firm and in-house practices have given him substantial experience in federal and state courts throughout the country.  He has briefed matters to the United States Supreme Court, Federal Circuit Courts of Appeals, and State Appellate Courts, and successfully argued many of them.  His practice has addressed a variety of employment and labor issues involving the ADA, FMLA, Title VII, and FLSA, as well as ERISA, employee benefits, class action, antitrust, some LMRDA, and bankruptcy.

One of William's cases headlined the Chicago Daily Law Bulletin and gathered local public interest as the outcome determined the application of a taxing statute over 40 years.  There, William secured a reversal and remand with directions to the Cook County circuit court to enter summary judgment for his client and a judgment of more than $37 million for that particular fiscal year.  The court on remand entered summary judgment and the entire judgment was collected.  In another case, also headlined in the Chicago Daily Law Bulletin, the Seventh Circuit held that attorney's fees in ERISA cases are not subject to a proportionality standard.  And, in a case selected by the Missouri Lawyers Weekly as one of the 10 most important opinions of 2005, the Eighth Circuit upheld the entry of contempt sanctions against the defendants' attorneys for advising their clients not to pay debts owed to the William's clients.

William is admitted to the Illinois bar (1989), the United States Supreme Court, the United States Court of Appeals for the Sixth, Seventh, and Eighth Circuits, and the United States District Courts for the Northern District of Illinois, the Central District of Illinois, the Eastern District of Wisconsin, and the Western District of Michigan.  He is also a member of the Trial Bar for the United States District Court for the Northern District of Illinois.
