In the field of criminal justice, evidence serves as the cornerstone for establishing legal facts; yet when the legality of the evidence itself is questionable, the entire edifice of factual truth risks collapse. The exclusion of illegally obtained evidence thus stands as a critical line of defense against this very risk. It not only embodies the heart of procedural justice but also serves as an indispensable safeguard for protecting the fundamental human rights of suspects and defendants—and for preventing wrongful convictions and miscarriages of justice.

The Criminal Procedure Law and its related provisions have established a relatively comprehensive set of rules for excluding illegally obtained evidence. Drawing on legal statutes and cases handled by the author, this article will explore the review mechanisms and complex challenges encountered in practice from the dual perspectives of “form” and “substance.”


 


 


 

I. Illegality of Form: Exclusion of Evidence Under Procedural Irregularities


 


 


 


 


 


 


 


 


 


 


 


 


 


 


 


 


 

In the current criminal justice context, illegally obtained evidence is distinguished between a broad and a narrow sense, which directly determines the scope of application and the review logic of exclusion rules.

Among these, the evidentiary methods used to obtain narrowly defined illegal evidence directly violate the fundamental human rights of the person whose evidence is being collected, or the evidence-gathering process clearly fails to comply with statutory provisions. The core of reviewing such evidence lies in assessing the severity of the illegality of the evidence-gathering act. For narrowly defined illegal evidence, the law explicitly stipulates that “such evidence shall be excluded.” In contrast, broadly defined illegal evidence refers to all evidence collected in violation of statutory procedures—this category includes not only narrowly defined illegal evidence but also evidence whose collection methods or procedural flaws may potentially undermine judicial fairness. Therefore, broadly defined illegal evidence requires a dual review: one assessing the procedural illegality and the other evaluating the risk of harm to judicial fairness. As for evidence other than narrowly defined illegal evidence that has other issues regarding its legality, the law does not prescribe a direct exclusion rule; rather, it states that such evidence “may not be used as the basis for reaching a verdict.”

Illegally obtained evidence in terms of “form” primarily refers to evidence whose collection methods or procedures violate legal provisions. According to current legal provisions, such evidence falls within the broad scope of illegally obtained evidence.


 


 


 


 


 


 


 


 


 

(1) Illegality of Evidence-Gathering Methods: Infringement on Fundamental Human Rights


 


 

 


 


 


 


 


 


 


 


 


 


 


 


 


 


 


 


 


 


 


 


 


 


 


 


 


 


 


 


 


 


 


 


 

Although we are no longer in a purely “confession-centered” system, due to the long-term influence of cultural traditions and practical experience, verbal evidence—especially the statements made by suspects and defendants themselves—still occupies a very important position in criminal cases and often becomes the central focus of disputes over the exclusion of illegally obtained evidence. Depending on the nature of the evidence-gathering subject and the formal differences in the illegal methods employed, the law has established separate review rules accordingly.


 


 


 


 


 


 


 


 

1. Illegally obtained evidence from criminal suspects and defendants


 


 


 

According to the Criminal Procedure Law, any statements obtained from criminal suspects or defendants through “illegal methods such as torture and coercive interrogation” must be excluded. In accordance with the Interpretations of the Criminal Procedure Law, the Provisions on Strict Exclusion of Illegally Obtained Evidence in Handling Criminal Cases (hereinafter referred to as the “Strict Exclusion Provisions”), and the Procedures for Excluding Illegally Obtained Evidence in Handling Criminal Cases (hereinafter referred to as the “Exclusion Procedures”), these illegal methods specifically include “violent means such as beating or unlawful use of restraints, or other cruel and inhumane treatment,” “methods involving threats of violence or serious harm to the legitimate rights and interests of the suspect or their close relatives,” and “illegal methods such as unlawful detention or other forms of unlawful restriction of personal freedom.” Moreover, the Opinions on Establishing and Improving the Working Mechanism for Preventing Wrongful Criminal Convictions stipulate that “methods such as freezing, starvation, exposure to the sun, roasting, and fatigued interrogations” also constitute illegal methods on a par with torture and coercive interrogation.


 


 


 


 


 


 

Based on the specific circumstances listed in the above-mentioned provisions, if a relevant statement was obtained through violent methods such as beating or unlawful use of restraints, or through disguised forms of physical torture—including freezing, starvation, exposure to the sun or heat, prolonged interrogation until exhaustion—as well as through threats involving violence or serious harm to the legitimate rights and interests of the individual concerned or their close relatives, such means must also reach the threshold of “causing the person to suffer unbearable pain and make a statement against their will” before they can be deemed “required to be excluded.” In contrast, statements obtained through illegal methods such as unlawful detention or other unlawful restrictions on personal freedom are not subject to any such threshold requirement. The former not only requires the “formal” element of unlawful interrogation but also imposes a strict requirement regarding the severity of the treatment; the latter, however, is not subject to any such requirement.


 


 


 


 


 


 

In a “black society” case in which the author participated as a defense counsel in Liaoning, several defendants were subjected to various forms of torture and coercive interrogation—including beatings, electric shocks, and threats—while under residential surveillance at designated locations. Subsequently, these defendants were taken to police stations and other investigation sites for questioning and record-taking. Following pre-trial conferences and court proceedings, numerous statements obtained from several defendants were ruled to be illegally obtained evidence and thus excluded from the trial. Among them, the defendant represented by the author had been beaten prior to questioning and bore obvious injuries. Moreover, the defendant was subjected to prolonged, exhausting interrogations, hunger-induced interrogations, and unlawful use of restraints—including being handcuffed behind the back, especially for extended periods—during the course of questioning.


 


 


 


 


 


 

According to the “Regulations on the Procedures for Handling Criminal Cases by Public Security Organs” (hereinafter referred to as the “Criminal Case Procedures Regulations”) and the “Strict Provisions on the Exclusion of Illegally Obtained Evidence,” “threats, inducements, and deception” directed at criminal suspects and defendants are also considered illegal methods on a par with torture and coercive interrogation. However, in conjunction with other relevant provisions—especially other articles within the “Strict Provisions on the Exclusion of Illegally Obtained Evidence”—in practice, only evidence obtained through severe “threats” is likely to constitute illegally obtained evidence that “must be excluded” in the narrow sense.

For example, confessions obtained by investigators through threats—such as threatening to hold the close relatives of a suspect or defendant criminally liable or subjecting those close relatives to coercive measures like criminal detention—should also be excluded as illegal evidence, as such actions violate the suspect’s and defendant’s fundamental human sentiments and free will.


 


 


 


 


 


 

In the case of Zheng Moumou’s embezzlement, bribery, and abuse of power (Criminal Trial Reference No. 1140), In the first-instance trial, the court found that the details of the bribery provided by the briber did not match the statements made by the defendant, Zheng Moumou. Moreover, at the trial, Zheng Moumou denied having accepted bribes and claimed that the investigators had used the lure of bail pending trial and threatened to arrest his children in order to obtain his guilty confession. The prosecution failed to present any evidence demonstrating that the guilty confession had been legally obtained. Therefore, according to law, the relevant guilty confession should be excluded. After the procuratorial organ filed an appeal, the second-instance court nevertheless ruled to dismiss the appeal and uphold the original judgment.

The court’s reasoning in this case also makes it clear that the determination of whether a threat has reached a serious level must be made by taking into account the specific circumstances of each individual case. Generally speaking, verbal threats alone—when they merely restrict or deprive the suspect or defendant of their freedom of will to a limited extent—will not significantly influence the suspect or defendant’s decision. If, after weighing the relevant interests, the suspect or defendant concludes that confessing is more advantageous to them than resisting and thus admits the criminal facts, the likelihood that such confession is false is lower than if obtained through torture or coercive interrogation. However, if the method of threat exceeds certain bounds—for example, by seriously harming the legitimate rights and interests of the suspect or defendant himself or his close relatives, or by employing methods prohibited by law or practices that are morally intolerable in society—such threats should be deemed to have reached a serious level and fall within the category of “other methods causing mental suffering to the defendant” as defined in the Interpretation of the Criminal Procedure Law. Confessions obtained through such methods must therefore be excluded.


 


 


 


 


 


 

However, in practice, confessions obtained through threats that merely harm the legitimate rights and interests of the suspect himself and his close relatives remain relatively difficult to exclude outright. In a “black society” case that the author handled in Chongqing, investigators threatened the defendant: if he failed to make a confession exactly as instructed, his family members would be arrested; but if he complied with the instructions, he could be released on bail pending trial. Under these circumstances, the defendant ended up making a guilty confession as requested by the investigators. Although the defendant and his defense counsel filed a motion to exclude this record and any subsequent repetitive statements derived from it, the court of first instance nonetheless refused to initiate the relevant procedure, citing simply that “there were no grounds warranting the initiation of an investigation into illegally obtained evidence.”


 


 


 


 


 


 

According to the existing regulations, whether a suspect’s or defendant’s statement “should be excluded” hinges on whether it was obtained through unlawful means that caused them severe physical or mental pain or suffering, thereby inducing intense psychological fear and compelling them to make the statement against their will.

In this regard, confessions obtained solely through “enticement or deception,” if made by criminal suspects and defendants based on a mistaken belief but without causing them severe physical or mental distress, do not constitute “psychological coercion” and do not violate their fundamental human rights; thus, they do not fall within the narrowly defined category of “illegally obtained evidence that must be excluded.” Generally, such evidence is unlikely to be directly excluded during the course of litigation. Instead, its admissibility as a basis for reaching a verdict must be determined in conjunction with a review of its legality. Even more commonly, these pieces of evidence will be further evaluated in light of other available evidence, with a comprehensive assessment of the authenticity of the relevant evidence content ultimately determining whether it can serve as a basis for the final verdict.

However, if the suspect or defendant is induced—by fabricating claims that they or their close relatives are suffering from terminal illnesses—to make a guilty confession according to specified requirements, taking advantage of their desire to secure bail as soon as possible in order to receive treatment or care for a loved one, this practice no longer constitutes mere deception. Rather, it amounts to a threat that exploits fundamental human rights and emotional bonds, potentially constituting psychological coercion. Consequently, any statements obtained under such circumstances should also be excluded as illegally obtained evidence.


 


 


 


 


 


 

In the case involving Zheng Moumou’s embezzlement, bribery, and abuse of power, the court’s reasoning also held that Zheng Moumou’s confession of accepting bribes was influenced not only by the threat that his daughter and son-in-law had been detained by the procuratorial authorities, but also by the investigators’ promise to release him on bail pending trial once he confessed to accepting bribes—thus, the investigators simultaneously used the promise of bail as a form of inducement toward Zheng Moumou. Zheng Moumou’s defense was corroborated by materials such as interrogation transcripts. This method of combining inducement with threats to some extent intensified the coercive effect, causing the defendant considerable mental anguish.


 


 


 


 


 


 

In summary, evidence obtained through violent methods, disguised forms of corporal punishment, or threats involving violence or serious harm to the legitimate rights and interests of the suspect or defendant and their close relatives—methods that inflict severe physical torture on the suspect or defendant or cause them intense psychological suffering—clearly constitute a direct violation of their fundamental human rights and run counter to basic moral principles. Given that the illegality of these methods is sufficient to compel the suspect or defendant to make a statement against their will, regardless of whether the specific content of such a statement is true or false, the evidence should be categorically excluded precisely because of the cruel and inhumane nature of the means used to obtain it.

Moreover, if the suspect or defendant has been unlawfully detained, the environment and circumstances in which they find themselves are already sufficient to evoke serious fear. Under such circumstances, regardless of whether other illegal practices—such as torture or coercive interrogation—have occurred, and irrespective of the severity of those other illegal methods, any statement obtained under these conditions should be directly excluded, given the fundamental illegality and violation of human rights that constitute the very basis for obtaining such evidence.


 


 


 


 


 


 


 


 


 

2. Illegally obtaining evidence from witnesses and victims


 


 



 

The Criminal Procedure Law stipulates that witness testimonies and victim statements obtained through “illegal methods such as violence or threats” must be excluded. The “Strict Provisions on Exclusion of Illegally Obtained Evidence” and the “Procedures for Excluding Illegally Obtained Evidence” explicitly state that “illegal restriction of personal freedom” also constitutes an illegal method on a par with “violence and threats.”


 


 


 


 


 


 

Compared to the exclusion rules applicable to the statements of criminal suspects and defendants, the relevant provisions adopt a significantly lower standard for excluding witness testimony and victim statements—simply the existence of formal illegal methods is sufficient, without requiring that such methods actually compel the relevant individuals to act against their will.

However, in practice, during the process of obtaining evidence from witnesses and victims—particularly in major cases such as official misconduct crimes and “organized crime” cases—investigators still sometimes resort to threats or even violent measures against witnesses and even so-called “victims” in order to establish that these individuals have committed the corresponding crimes. Even when witnesses and victims themselves claim that they were threatened and deny the authenticity of the evidence, such evidence often remains difficult to be directly excluded.


 


 


 


 


 


 

In the aforementioned “organized crime” case in Liaoning Province, several witnesses testified in court that the contents of their statements were not true. Moreover, during their questioning, investigators employed varying degrees of threats; indeed, some witnesses were even subjected to interrogation while handcuffed behind their backs in the same manner as the defendants—a clear violation of the fundamental rules governing the collection of witness testimony. Nevertheless, despite these obvious violations involving “violence and threats,” the relevant evidence has not been directly excluded; rather, its admissibility must still be confirmed through court proceedings.

Even more complicated is the fact that the law does not explicitly require investigators to simultaneously record audio and video during the process of gathering evidence from witnesses and victims. As a result, it becomes impossible to verify through audio and video recordings the legality of the questioning process, as well as the consistency and authenticity of the recorded statements with the actual content of the interviews.

If the court does not require or notify witnesses and victims to appear in court for cross-examination, thereby failing to verify their testimony on the spot, then under “document-based proceedings,” it becomes impossible both to negate the admissibility of witness testimony and victim statements on the basis of formal illegality and to challenge their substantive unreliability. On the contrary, such a procedure might even prove more detrimental than illegally obtained evidence against the suspect or defendant.
