2. In what circumstances does secret audio recording constitute a crime?

a) Violation of the confidentiality of communication (Turkish Penal Code Article 132)

individuals' communications, such as phone calls, messages, emails, and WhatsApp conversations, without legal basis constitutes a crime under Article 132 of the Turkish Penal Code.

For example:

• Secretly taking screenshots of your spouse's/employee's WhatsApp conversations and distributing them ,

• Listening to and recording a conversation that is not yours (a phone call you were not a party to)

This could constitute a crime of violating the confidentiality of communications.

b) Listening to and recording conversations between individuals (Turkish Penal Code Article 133)

Secretly listening to and recording conversations held in a private setting where it is not expected to be heard by everyone (such as a home, meeting room, or vehicle) is regulated as a crime under Article 133 of the Turkish Penal Code .

Specifically here:

• A third party secretly recording a conversation between other people,

• Placing a hidden audio device, bug, or hidden camera inside the room

This may give rise to criminal liability.

c) Violation of the right to privacy (Turkish Penal Code Article 134)

Secretly recording, storing, or disseminating audio or video footage relating to a person's private life is also a crime under Article 134 of the Turkish Penal Code

For example:

• Placing a hidden camera in the bedroom of the house and recording,

• Secretly recording conversations that concern private life,

• Sharing these recordings on social media

It could be subject to a criminal investigation.

Is recording a conversation in which a third party is involved always a crime?

The crucial distinction here is that a recording made by a party to the conversation is not equivalent to a recording made by a third party

• In the practice of the Supreme Court, in some exceptional cases, recording a conversation to protect one's rights or prove something may not be considered a crime and may be accepted as evidence.

• Conversely, secretly recording a conversation you are not a party to is generally a crime under Article 133 of the Turkish Penal Code.

Furthermore, even recording a conversation in which one is a party can be considered problematic from both a criminal and evidentiary law perspective if it is done in a completely planned manner, with the intention of setting a trap, and when other evidence could be obtained

4. Can Secret Audio Recordings Be Used as Evidence?

The answer to this question depends on factors such as "is it a criminal case or a civil case?" , "who made the recording?" , and "was there any possibility of obtaining other evidence?"

• Articles 206/2-a and 217/2 of the Code of Criminal Procedure stipulate that evidence obtained unlawfully cannot be presented in criminal proceedings, and that a crime can only be proven with legally obtained evidence

• Article 38/6 of the Constitutionstates that findings obtained illegally cannot be accepted as evidence.

Therefore, the general rule is:
👉 If a secretly recorded audio file has been obtained illegally, it cannot, as a rule, be used as evidence in court.

b) Exceptions: The Supreme Court's "necessity and last resort" approach

Supreme Court rulings particularly emphasize the following criteria:

1. Is the person recording a direct party to the conversation?

   • In some court decisions, it may be considered lawful for a party to a conversation to record it in a sudden situation and if there is no other way to prove the alleged insult, threat, blackmail, bribery, or tort committed against them

2. Was there any other way to obtain evidence?

   • If an event can be proven through other means such as witnesses, correspondence, or official records, then secretly recording something simply to obtain stronger evidence is generally considered illegal.

3. Was the recording made as a "trap"?

   • Recordings obtained by provoking the other party, asking leading questions, and essentially staging a scenario are often illegally obtained evidence .

4. To what extent does the recording violate privacy?

   • Secret recordings, especially those made in the most private areas such as bedrooms and bathrooms, often a violation of privacy and are generally rejected as evidence.

The Supreme Court of Appeals sometimes "audio recordings are illegally obtained evidence and cannot be considered as evidence," ; other times a last resort and only if absolutely necessary . For example, in some divorce cases, reference is made to decisions (such as Supreme Court of Appeals 2nd Civil Chamber, 2016/20574 E., 2018/9685 K.) that consider secret recordings as illegally obtained evidence.
