DLH attorneys have represented clients in complex cases involving the construction of the Chicagoland Speedway and the Naperville Municipal Center, and in the College of DuPage Library (mold) cases. DLH attorneys have successfully defended product liability cases involving professional and consumer products nationwide, as coordinating and local counsel.

DLH's complex litigation has involved, for example, construction bid protest and injunctions on multi-million dollar construction projects where the apparent low bidder was not qualified to perform the job; as well as handling multiple payment and performance bond claims when large, regional contractors have gone out of business without paying dozens of their subcontractors.
