The legal framework
In criminal proceedings, evidence is any fact that helps establish the existence or non-existence of a crime, the perpetrator, and the relevant circumstances for resolving the case, and the law also allows any other means of evidence that is not expressly prohibited. At the same time, the request for the administration of evidence may be rejected if the evidence is irrelevant, unnecessary, impossible to obtain, or contrary to the law; and evidence obtained illegally cannot be used in the criminal proceedings. Its value is not predetermined by law but is assessed freely within the entire evidence process.
In matters concerning recordings, the Code of Criminal Procedure distinguishes between recordings made by parties or other persons and those obtained through special procedures. Article 139(3) allows the use of recordings made by parties or other persons as evidence when they relate to their own conversations or communications with third parties, and any other recordings may be used as evidence if not prohibited by law. Additionally, the questioning of the suspect or defendant during criminal proceedings is recorded either audio or audio-video, and if this is not possible, the reason must be explicitly stated. There is also a special regime for recordings obtained from specific information gathering activities, for which the law provides distinct conditions of use and a specific procedure for contesting them.
When they are useful
Audio and video recordings are useful especially when they directly capture the content of a discussion relevant to the crime and complement what cannot be easily proven through witnesses or written records. In practice, they become all the more valuable as they come from one of the interlocutors and reproduce a conversation actually conducted by the person who makes them available to the judicial authorities. The Supreme Court held, in a case where the injured person submitted an audio file containing his own recording of a discussion with the defendant, that such evidence can be admitted precisely because the author of the recording was a participant in the conversation, and the defense’s objections essentially concerned its reliability rather than its illegality.
From this perspective, the usefulness of a recording does not lie solely in the fact that it „exists”; it lies in the fact that it fixes exactly what was said, when it was said, and in what context. In cases where the dispute concerns threats, pressures, promises, admissions, or negotiations conducted outside a formal framework, a recording can have real probative value, but only if it can be credibly linked to the interlocutors, the moment of its occurrence, and the integrity of the recording medium on which it was stored.
When they can be contested
Records can be contested, first of all if they were obtained illegally. The Code excludes evidence obtained illegally, and if the act that ordered or performed the evidence is null and void, the evidence is excluded and the corresponding supporting material is removed from the file. This includes, for example, situations where the technical surveillance measure was not implemented by the competent authority or the legal conditions of the authorization were not met. The High Court found the absolute nullity of some ambient audio-video recordings made during a technically implemented surveillance carried out illegally, holding that the measure should have been implemented by the prosecutor or the criminal investigation body of the judicial police, not by the Romanian Intelligence Service.
Secondly, a recording can be challenged when there are serious doubts regarding its authenticity, completeness, or origin. The Supreme Court specifically examined, in a case concerning influence peddling, whether the optical supports contained the original recordings or merely faithful copies, and the defense requested their expert examination to verify whether the content or the voice recorded had been manipulated. This shows that, beyond admissibility, authenticity remains a practical and essential issue.
Thirdly, there is a privacy filter. Article 139(4) protects the attorney-client relationship: if technical surveillance also targets the communications between the lawyer and the suspect or defendant they are defending, the obtained evidence cannot be used and must be destroyed. In such situations, the issue is no longer just one of credibility but one of explicit legal prohibition.
Finally, a distinction must be made between a recording made by a participant in the discussion and one made by a third party interested in provoking a reaction or confession. In doctrine, this type of evidence has been criticized precisely from the perspective of reliability and the risk of distorting the context, and this criticism becomes relevant whenever the recording does not spontaneously capture a behavior but seeks to artificially obtain a statement.
What really matters in front of the court
In practice, a good recording is not just one that is „clear,” but one that can be technically and legally defended: who made it, with what device, at what moment, in what context, whether the recording is complete, whether the transcription is faithful and whether there are no logical or technical gaps. If these elements are solid, the recording can become an important piece of evidence. If they are missing, the defense has real room to request the removal of the evidence or, at least, to significantly reduce the probative value of the evidence.
Therefore, audio and video recordings are, in criminal law, high-potential evidence, but also with appropriate vulnerabilities. They are helpful when obtained legally, from a conversation participant or through an authorized procedure, and are contestable when problems of legality, authenticity, integrity, or confidentiality arise.
In a criminal trial, the difference between a useful piece of evidence and an excluded piece of evidence often lies less in its content and more in the way it was obtained and preserved.
