Workplace Investigations

The privilege of investigation materials concerns a rather limited amount of cases. In practice, materials may be considered privileged in connection with the litigation process under the Procedural Code (4/1734). For example, communications between a client and an attorney may attract protection against forcible public disclosure.

Professional advice given by an "advocate" to a client is protected as “privileged communication” and is not admissible as evidence in a court of law. Such privilege may not attach to advice or communications involving in-house lawyers as they are not licensed advocates (since they are expected to surrender their bar licences when they take on in-house roles). This is a grey area as there are conflicting judicial precedents on this. Hence, communications, documents or information gathered during an investigation conducted entirely internally may not be legally privileged and may be discoverable in a dispute. That said, companies generally mark sensitive communications with in-house attorneys as privileged and confidential in an attempt to protect the same.

For the above reasons, investigations conducted by external advocates have better chances of retaining legal privilege. However, the following will not be treated as privileged information:

• any correspondence about the commission of a crime or fraud by the client; and
• the observations of an attorney that would suggest that a crime or fraud will be committed by the client.

No law recognises the common law concept of “attorney-client privilege” in Korea. However, communication with an attorney is protected to some extent under certain laws, such as the Constitution, the Attorney Act, the Criminal Procedure Act, and the Civil Procedure Act. This protection is based on the attorney’s confidentiality obligation, which prohibits an attorney from divulging confidential matters acquired in the course of representing clients, unless otherwise prescribed by law. This confidentiality obligation generally allows an attorney to refuse to testify or comply with document production orders for information or materials the attorney obtained in the course of his or her duties that relate to the confidential information of clients.

In addition, there could be instances where materials from an investigation conducted in Korea may become subject to discovery outside of Korea. It is, therefore, important to ensure investigation materials are privileged under the relevant non-Korean laws in the jurisdictions where attorney-client privilege is recognised (eg, the US).
