The Illinois Supreme Court found that the suspension of the physician was proper because the physician had notice of the claims against him and the hospital committee took action that it was authorized to take under the hospital bylaws. The Illinois Supreme Court also found that the hospital did not properly follow its bylaws when it denied the application for privileges renewal, however, that issue was rendered moot because of the proper imposition of the summary suspension.
