Abstract: The case acceptance scope of juvenile courts serves as a foundational element of the juvenile adjudication system,determining the extent of judicial intervention in safeguarding minors' rights and interests and directly shaping the breadth and depth of such protection.Legislative developments and judicial practice demonstrate an evident expansion of this scope,though theoretical perspectives on this trend remain divided among negation,affirmation,and compromise viewpoints.Justification for expanding juvenile courts' case acceptance scope rests on three pillars:functional superiority,as these courts excel in professional capacity,procedural design,and trial models;value leadership,guided by comprehensive protection and preventive justice principles that support inclusion of civil and administrative cases;and interpretative openness in legal norms,where terms such as "cases involving minors" in Article 101 of the Law on the Protection of Minors and open-ended wording in Articles 7 and 8 of the Opinions on Juvenile Adjudication allow adaptive responses to evolving social needs while maintaining legal stability.The expansion pathway should adhere to protective,relevant,and saturation principles,prioritizing minors' property disputes,serious misbehaviors,public interest litigation,and categorized administrative cases to clarify juvenile courts' jurisdictional boundaries.

Key words: juvenile courts, case acceptance scope, rights and interests of minors, serious misbehaviors, Law on the Protection of Minors, Opinions on Juvenile Adjudication
