In In re In re Tyrone W., 326 Ill. App. 3d 1047, 1049, 762 N.E.2d 1159, 261 Ill. Dec. 232 (2002) the respondent's mother indicated at one hearing that she could provide the State with the respondent's father's address. In re Tyrone W., 326 Ill. App. 3d at 1050. However, the State made no attempt to locate the respondent's father. In re Tyrone W., 326 Ill. App. 3d at 1050. On appeal, the respondent argued that the lack of notice to his father deprived the circuit court of jurisdiction. In re Tyrone W., 326 Ill. App. 3d at 1049. The appellate court rejected this argument, stating that "although the State could have been more diligent in its attempt to locate and notify the noncustodial father of the proceedings, the minor's failure to raise this issue in the trial court, particularly where he was represented by counsel, renders his jurisdictional argument waived on appeal." In re Tyrone W., 326 Ill. App. 3d at 1050.
