This research deals with the topic of objection to a ruling made in defendant absence and reconsideration of the cases of delinquent juveniles as two of the protections prescribed for the juvenile delinquent in his criminal justice. Although a juvenile delinquent shares with the adults the general provisions of these two appeals, however, there are provisions specific to the delinquent juvenile that the research deals with in explanation and detail. The problem of the research revolves around the fact that the Omani legislative texts in the field of challenging the decision through objection and reconsideration are limited in some aspects to providing full protection for the delinquent juvenile, which calls for standing on it and proposing the appropriate solutions. The research aims to present the provisions of objection to a ruling made in defendant’s absence and reconsideration the general procedural rules, as well as presenting their provisions in the legal rules for delinquent juveniles, and to investigate legal loopholes that would affect the justice of the delinquent juvenile and to suggest appropriate solutions to it. The research is based on several scientific approaches, namely: inductive methods, analytical methods, comparative methods and practical approaches. The research concludes that Omani law included general rules to objection to a ruling made in defendant absence and reconsideration juvenile cases, and set some legal rules for delinquent juveniles, despite this, the legislative texts contain legal lacunae for which legislative treatment is required to ensure a fair trial for a juvenile offender. At the conclusion of the study, the researcher presented a number of suggestions and recommendations to improve the juvenile delinquent legal system in Oman.
