Alarm Detection Systems, Inc. v. Village of Schaumburg

Several fire alarm companies filed a lawsuit against the Village of Schaumburg seeking to enjoin an ordinance that required commercial and multi-family properties to route fire alarm signals directly to a regional emergency-dispatch center. Plaintiffs alleged that the ordinance violated the Contracts Clause and tortiously interfered with their contracts and prospective economic advantage. The district court granted summary judgment in favor of the defendant and plaintiffs appealed. The Seventh Circuit affirmed, finding that the plaintiffs failed to offer evidence that the ordinance caused their existing clients to breach their contracts or that the defendant intended to interfere with their business relationships. (SCUDDER and JACKSON-AKIWUMI, concurring)
