What should be paid attention to in audio (video) evidence?

Recording evidence collection is not simple, there is technical content, according to judicial practice, summarized ten key points:

1. It should be collected by legal means.

This is the foundation. There are many factors that are used to judge legality, generally speaking, when the two parties communicate face-to-face, one party holds a recording device or one party directly records when communicating, which is legal in terms of means.

2. There should be some basic elements in the content of the conversation.

Factors such as time, identities and locations of both parties should be included in the content of the conversation, which often play an important role in the case, and it is best to have a clear confirmation during the communication process.

3. Recording evidence collection should be done as soon as possible.

In the absence of major conflicts between the two sides, at least before the prosecution is made, there is still a chance to collect evidence through audio recording. It is generally difficult to succeed in collecting evidence after an indictment.

4. Set the key points of the conversation according to the facts of the case.

Based on the facts of the case and other evidence in hand, the key points of the recording evidence should be fixed, consistent with the purpose of the appeal, and mutually corroborating with other evidence. For key content, if possible, check it multiple times.

5. The tone of the conversation and the way of communication should be designed in advance.

Express yourself naturally, otherwise the other party may be alert, resulting in a loss of the opportunity to collect evidence;

Do not talk in a threatening tone, as evidence obtained by means of threats may be found to be illegal;

Try to communicate as calmly as possible, and expressions in the process of agitated quarrels may be determined to be non-genuine expressions;

The language content that involves key points should be clear and unambiguous;

If possible, the key content should be clearly expressed by the other party, rather than just replying with "um" and "ah";

6. The facts to be fixed in the recording and evidence collection are not the views of all parties on the facts.

The judge shall judge right and wrong, and the purpose of the parties' evidence is to fix the objective facts that have occurred, and not to be entangled in the different views of the parties or their views on the law.

7. Pay attention to controlling the time and rhythm of the conversation.

Time in court is precious, and the time for recording evidence should not be too long. If it is not possible to collect evidence in a short time, it is best to control the key content of recording forensics, and it is best to focus on one or several points in time, and not be too scattered.

8. Pay attention to retaining the original carrier of the recording.

When there is a dispute about the authenticity of the audio-visual materials, judicial appraisal may be required, and the original audio-visual materials should be provided to the court, so the original carriers should be retained, and they should not be lost or overwritten after copying.

9. Complete recording evidence should be provided, and no unauthorized editing or interception should be allowed.

In order to preserve the integrity of audiovisual materials, audio recording evidence after editing and interception is usually invalid.

10. The audio evidence provided to the court must have a text version.

The way to provide audio evidence to the court is usually to engrave a disk, and to give a copy to the other party, the other party should carefully verify, and the court should be provided with a text collated version, which is the basic requirement of form.
