Video Conference Testimony in International Criminal Cases in Turkey: Law No. 6706 Article 9 and Mutual Legal Assistance

1. Video conference is a form of international judicial assistance

When the person is in another state, the Turkish court cannot simply compel remote participation through domestic technical instructions. Cooperation of the foreign authority is required.

Article 9 supplies the domestic cooperation basis, while treaties can add detailed conditions.

The request should explain why video evidence is needed.

2. Witnesses are common users of the mechanism

A witness abroad can give evidence without physically entering Türkiye where the requested state accepts the video procedure.

The foreign authority verifies identity and local legal formalities.

The Turkish court can ask questions within the agreed procedure.

3. Victims and complainants can also participate remotely

International victims may face cost, visa, safety or trauma barriers to travel.

Video participation can preserve access while maintaining the Turkish criminal process.

Protective measures should be considered for vulnerable victims.

4. Experts can be heard from abroad

A foreign forensic, medical or technical expert can explain a report through video where cooperation rules permit.

The expert’s qualifications and identity should be established.

Documents used during testimony should be shared through a secure judicial channel.

5. Defendant participation raises stronger fair-trial concerns

Remote participation of an accused must respect defence rights and the rules of the requested state/treaty.

The defendant must be able to communicate effectively with counsel and understand interpretation.

Video should not be used simply to avoid a legally required physical appearance.

6. Identity verification is mandatory

The requested authority should verify the participant’s identity from official documents.

The record should identify location, persons present and technical channel.

Unverified consumer video accounts are not sufficient judicial identity evidence.

7. Interpretation must be arranged in advance

International video testimony can involve Turkish, the foreign state’s language and the witness’s language.

The court should decide whether one or multiple interpreters are needed.

Interpretation failure can undermine evidence quality and defence fairness.

8. Oath and warning procedure must be legally valid

Witnesses and experts should receive the warnings/oath required by the applicable procedure.

The foreign authority can assist in administering formalities.

The record should state what warning was given.

9. Cross-examination and questioning should remain meaningful

Defence and prosecution should be able to ask permitted questions without technical obstruction.

Audio delay, connection problems and document visibility should be recorded.

If the connection prevents effective examination, continuation should be considered rather than pretending the hearing succeeded.

10. Recording and minutes are essential

The Turkish court should create formal minutes and preserve recordings where law and technical systems permit.

The foreign authority’s certification can become part of the case file.

Time zone, start/end time and interruptions should be recorded.

11. Confidential lawyer-client communication must be protected

If the defendant participates from abroad, counsel must have a confidential communication method where required.

A microphone controlled by police or other participants can create privilege concerns.

The court should plan confidential breaks.

12. Documents used during the hearing should be authenticated

A witness should know which document is being shown and the record should identify it.

Private screen-sharing of files not admitted to the case can create confusion.

Judicially transmitted copies are preferable.

13. The requested state can impose conditions or refuse

Its domestic law may restrict video evidence for certain roles or offences.

The treaty can permit refusal for sovereignty/security or other reasons.

The Turkish court should adapt the request to the destination state.

14. A lawyer cannot create an official Article 9 hearing alone

Counsel can request that the court/prosecutor use video assistance and explain why it is necessary.

The actual state-to-state request is made by the competent judicial/central authority.

A private Zoom interview is not equivalent to court testimony.

15. Urgency should be explained with evidence

Illness, visa impossibility, imminent trial date or risk of evidence loss can support expedited treatment.

International assistance still requires the foreign state’s process.

Late requests can cause adjournment.

16. Remote evidence is still evaluated on credibility and legality

The fact that testimony was taken through an official video link does not make it automatically true.

The Turkish court evaluates consistency, other evidence and credibility.

Defence can challenge both content and procedure.

17. Video testimony should be planned at the beginning of an international case

Identify foreign witnesses early, obtain accurate addresses and determine treaty channels before the trial approaches.

Early planning reduces postponements.

Where physical attendance is genuinely necessary, video should not be used as an inadequate substitute.

Conclusion

Article 9 video conference is a useful international evidence tool when implemented as formal judicial cooperation. Identity, interpretation, defence and record safeguards distinguish judicial testimony from an ordinary online call.
