The instant action was filed in the circuit court of Jackson County. It comes before us on appeal from a summary judgment entered in favor of hospital. • 1 On review of a trial court's entry of summary judgment, a reviewing court's sole function is to determine whether the trial court correctly determined that there were no genuine issues of material fact, and if there were none, whether judgment for the moving party was correctly entered as a matter of law. ( Hennessy v. Foley (1987), 154 Ill. App.3d 1039, 1042, 507 N.E.2d 1258, 1260.) Hospital correctly points out that our review is even more limited in this case by the "rule of non-review" pertaining to medical staff decisions made by a private hospital.
