An updated version of our guide, "Non-Compete Laws: Illinois," is now available. It reflects the recent decision of the Illinois Supreme Court in Reliable Fire Equipment Company v. Arredondo, et al., which resolved several years of confusion over the appropriate standard for enforcing non-compete agreements in Illinois.

On December 1, 2011, the Illinois Supreme Court issued its opinion in Reliable Fire Equipment Company v. Arredondo, et al., which resolved several years of confusion over the appropriate standard for enforcing non-compete agreements in Illinois.

The Illinois Supreme Court will soon hear oral argument in a case that could resolve the current confusion with regard to non-compete law among Illinois' appellate districts.

In December 2010, in Reliable Fire Equipment Company v. Arredondo, the Illinois Court of Appeals for the Second District directly addressed Sunbelt Rentals, Inc. v. Ehlers, a troublesome 2009 case from Illinois' Fourth District that rejected Illinois' longstanding requirement that an employer must have a legitimate business interest in order to enforce a non-compete agreement. According to the Court in Reliable Fire, restraints on trade have long been disfavored by the Courts and the "legitimate business interest test" remains an important "threshold question" which allows the Court to analyze "whether the employer has an interest other than suppression of ordinary competition." Thus, depending on the district in which they are located, Illinois employers may be subject to different standards for enforcement of non-compete agreements.
