法律在社会生活中起着调整社会关系的重要作用。但是在实际的司法过程中法律规则自身诸多的局限性,往往阻碍着司法进行公正、有效、及时地判决。法官自由裁量权的行使则相对弥补了法律适用过程中的诸多的缺陷。因而,法官自由裁量权的合理行使成为了社会日益关注的问题。本文认为只有建立科学有效的保障体系,才能充分发挥法官自由裁量权的最大功效,防止权力滥用,杜绝司法腐败和司法专横,实现司法公正。 Law plays an important role in social life by adjusting social relations. However, many limitations of the rule of law in the actual judicial process often prevent the judiciary from judging justice in an effective and timely manner. The exercise of the discretion of the judge relatively makes up for many shortcomings in the application of the law. Therefore, the reasonable exercise of the judge’s discretion has become an issue of increasing social concern. This paper argues that only by establishing a scientific and effective guarantee system can we give full play to the maximum effectiveness of judges’ discretion, prevent abuse of power, eliminate judicial corruption and judicial autocracy, and realize judicial fairness.
