This question examines the rights of minors’ defenders. Article 476 of the Interpretation of the Supreme Court stipulates: "The investigation report transferred by the People's Procuratorate on the minor defendant's personality characteristics, family situation, social interactions, growth experience, reasons for the crime, performance before and after the crime, guardianship and education, etc., as well as the investigation report submitted by the defender The court should accept the written materials reflecting the above situation of the minor defendant. "So A is correct. Article 474 of the Interpretation of the Supreme Court stipulates that "when the people's court decides to apply summary procedures to a minor's criminal case, it shall seek the opinions of the minor defendant and his legal representative and defender. If the above persons raise objections, summary procedures shall not be applied." ". Therefore B is correct. Article 486 of the Interpretation of the Supreme Court stipulates that "after the minor defendant makes his final statement, the court shall ask his legal representative whether to make additional statements." Therefore, it is the legal representative and not the defender who has the right to make supplementary statements, so item C is wrong. The Supreme Court interpreted Article 466, Paragraph 2, which stipulates: "In addition to exercising their rights stipulated in Paragraph 2 of Article 270 of the Criminal Procedure Law in accordance with the law, other persons present may, with the consent of the court, participate in court education and other work for minor defendants. "So item D is correct. Choose ABD. for this question.
