People v. Dent 

Defendant was convicted of first degree murder; his conviction and sentence were affirmed on direct appeal. Defendant's postconviction petition was denied. Court properly denied Defendant's successive postconviction petition, which alleged actual innocence, after second-stage review, as Defendant lacked standing to pursue postconviction relief where he served his sentence on the challenged conviction prior to filing the successive postconviction petition. Thus, Defendant's liberty interest for the murder cannot be affected. (HALL and HOFFMAN, concurring.)
