Illinois Appellate Court
Civil Court
Postconviction Petitions
(Court opinion corrected 4/15/15.) In postconviction proceedings, doctrine of res judicata bars relitigation of any issues which have previously been decided by a reviewing court. Failure to swear grand jury does not divest court of subject-matter jurisdiction to enter a criminal conviction. Court is not required to conduct preliminary hearing where a defendant is indicted after initially having been charged in some other manner.(SCHOSTOK and BURKE, concurring.)
