In re G.C., 458 P.3d 70

Background

Minor G.C. admitted three Vehicle Code §10851 offenses (auto theft), wobblers, in Santa Clara; minute order and petitions labeled them felonies but the juvenile court did not expressly declare misdemeanor or felony as required by Welf. & Inst. Code §702.
The Alameda court conducted disposition (after transfer) and set maximum confinement consistent with felony treatment but again failed to make the §702 declaration; G.C. did not appeal that disposition within the appeal period.
A later §777 proceeding (probation-violation modification) was held in Santa Clara; the court maintained G.C. in parental custody and again did not declare the prior wobbler offenses as misdemeanors or felonies.
G.C. filed a timely appeal from the §777 disposition challenging certain probation conditions and also argued the earlier §702 omission; the Court of Appeal dismissed the appeal as to the §702 omission as untimely and rejected the argument that the omission was an unauthorized sentence.
The Supreme Court granted review to resolve appellate conflict and held that G.C. may not raise the §702 omission in the later appeal because the original dispositional order became final when not timely appealed, and the omission did not create an unauthorized sentence correctable at any time.

Issues

Issue	Plaintiff's Argument (People)	Defendant's Argument (G.C.)	Held
1. May a juvenile challenge a court’s failure under §702 to declare a wobbler a misdemeanor or felony in an appeal from a later §777 dispositional order after the original disposition became final?	The earlier disposition was final; challenge was untimely and cannot be raised in later appeal.	Juvenile proceedings are one case; a timely appeal from the later order should confer jurisdiction over all petitions and permit challenge.	Held: No. Failure to timely appeal the original dispositional order deprived appellate jurisdiction; later appeal cannot be used to attack that final order.
2. Does the court’s omission under §702 constitute an ongoing duty that must be corrected in subsequent proceedings?	No continuing statutory duty exists under §702 to revisit the designation in a later §777 proceeding.	§702 imposes a continuing obligation; court should have declared at the later proceeding as well.	Held: No. §702 contains no continuing-duty language like ICWA; Santa Clara had no obligation to revisit the final Alameda disposition in the §777 proceeding.
3. Is the §702 omission an "unauthorized sentence" that can be corrected at any time?	The omission creates an unauthorized sentence that is nonforfeitable and reviewable despite untimeliness.	The omission was jurisdictional/error of law that can be raised anytime to protect liberty interests.	Held: No. The omission was a forfeitable discretionary error, not an unauthorized sentence correctable at any time; remand would be required to exercise discretion and the error was not "clear and correctable" on its face.
4. Does barring the belated §702 challenge violate due process/liberty interests?	n/a (People argued finality and procedural rules).	Denying review of the §702 omission arbitrarily deprives a liberty interest in sentencing determinations.	Held: No due process violation; Hicks limited to jury-found factual rights and does not apply; enforcing timely-appeal rules here is not arbitrary.
