对少年犯进行定罪量刑的最基本原则是最有利于少年的原则。该原则是一项国际性原则。将这一原则作为我国刑事诉讼中对少年犯进行定罪量刑的基本原则也是恰当的。它涉及对少年权益的保护和少年的成长,是体现教育、感化、挽救的一个重要方面。但在适用最有利于少年这一原则时,应区别不同的犯罪情况,采取宽严相济的策略。 The most basic principle of conviction and sentencing of juvenile offenders is the one that best benefits juveniles. This principle is an international principle. It is appropriate to regard this principle as the basic principle of conviction and sentencing of juvenile offenders in criminal proceedings in our country. It involves the protection of the rights and interests of juveniles and the growth of adolescents. It is an important aspect of education, probation and salvation. However, when applying the principle that is most beneficial to juveniles, different criminal situations should be distinguished from each other and a tactic of strict and lenient cooperation should be adopted.
