Craig J. Duchossois Revocable Trust UAD 9/11/1989 v. CDx Laboratories, Inc.

# Court Ruling Summary: Duchossois Trust v. CDx Laboratories **What Happened** The Duchossois Trust had a written agreement with CDx Laboratories involving a promissory note—essentially a promise to pay money. CDx Laboratories failed to honor this agreement and tried to get out of the obligation by claiming the debt had been eliminated through three different legal maneuvers. **What the Court Decided** The court sided with the Duchossois Trust. The judge rejected all of CDx Laboratories' arguments for avoiding payment. The company could not prove that the debt was forgiven, that anyone had agreed to let them off the hook, or that the Trust had given up its right to collect. The court ordered judgment in favor of the Trust on the promissory note. **Why This Matters for Workers** This ruling reinforces that written agreements are binding. Employers cannot simply ignore contractual obligations by making vague claims about changed circumstances. For workers with signed employment contracts or compensation agreements, this decision shows courts will enforce the terms unless there is clear, documented proof of release from those obligations.
