What are the applicable conditions of the rule of arbitrariness of confession?

1. What are the conditions for expressing any rule? Arbitrary confession rule, also known as non-arbitrary confession exclusion rule, means that in criminal proceedings, only confessions made on the basis of the defendant's free will (that is, confessions that admit guilt) have evidential capacity; A confession made against the will of the parties or in violation of legal procedures is not a confession, but a confession. Is unacceptable and must be ruled out. According to the principle of self-sufficiency, if the defense disagrees with the confessions of criminal suspects and defendants quoted by the prosecution during the court trial, the judge should prohibit the prosecution from submitting the evidence to the court and should not use the evidence as the basis for judgment. However, it should be pointed out that although the arbitrariness of confession has an important influence on the authenticity of confession, there is no necessary causal relationship between the two. Arbitrary confessions are not necessarily true confessions. On the contrary, non-arbitrary confessions are not false confessions. Therefore, if the rule of confession arbitrariness is only based on the value evaluation of the influence of confession authenticity, simply understanding the value of the rule of confession arbitrariness from the entity will actually lead to insufficient understanding of the rule of confession arbitrariness. In fact, besides pursuing the value of substantive justice, the rule of confession arbitrariness is also of great significance to the realization of procedural justice. Second, what is the classification of criminal evidence? 1. Guilty evidence and innocent evidence are divided into guilty evidence and innocent evidence according to whether the proof function of evidence is to confirm or deny that the criminal suspect or defendant has committed a criminal act. Any evidence that can prove the existence of criminal facts and that criminal suspects and defendants commit criminal acts is guilty evidence; Any evidence that can deny the existence of criminal facts or prove that criminal suspects and defendants have not committed criminal acts is innocent evidence. 2. Verbal evidence and physical evidence are divided into verbal evidence and physical evidence according to the different forms of evidence. Any statement expressed as a person and evidence expressed in words are oral evidence; Written documents that are manifested as objects and traces and whose contents have evidential value, that is, physical evidence, are physical evidence. 3. Direct evidence and indirect evidence According to the different relationship between evidence and the main facts of the case, evidence can be divided into direct evidence and indirect evidence. Direct evidence is evidence that can directly show the main facts of a case; Indirect evidence is evidence that cannot directly show the main facts of a case alone and needs to be proved by combining with other evidence. To sum up, when trying criminal cases, judges should make judgments based on the evidence they have, and they cannot be convicted without evidence. There are many rules of evidence, among which confession is arbitrary. The application of this rule must be voluntarily recognized by the defendant. Extorting a confession by torture violates this rule, and the evidence obtained in this way is illegal and the judge will not accept it.
