Plaintiff filed a lawsuit after discovering that defendant allegedly had engaged in a fraudulent accounting scheme designed to reduce plaintiff’s compensation by expensing monies, which defendant received from Centegra Health Systems, directly to her. Plaintiff also learned that defendant was not a licensed professional corporation, even though she had given plaintiff prior assurances that she was properly registered. According to plaintiff, to induce her to join its medical practice, defendant expressly represented in writing that the “Corporation [was] registered to practice medicine in the State of Illinois.” Can the defendant’s failure to comply with the act’s certificate of registration requirement render the employment agreement void?
