Workplace Investigations

The legal situation regarding attorney-client privilege for investigation materials compiled by external advisors (in particular investigation reports) is unclear. In principle, there is no absolute protection against seizure by the public prosecutor in the relationship between client and lawyer. Such protection only exists in the relationship between the accused in a criminal proceeding and his criminal defence attorney.

In recent years, German courts have repeatedly issued different rulings on the question of whether investigation materials (at the company itself or a lawyer's office) may be seized. In 2018, the Federal Constitutional Court (BVerfG) ruled that the seizure of documents at the offices of an international law firm that is not based in Germany, and therefore can not invoke German constitutional rights, is lawful. However, the BVerfG did not comment on what would apply to seizures at law firms based in Germany.

For violations that could lead to the company itself being exposed to investigative proceedings at some point and possibly having to defend itself, there are, in our view, good arguments for investigation materials being subject to attorney-client privilege. Additionally, the lawyer's hand file, in which he usually keeps his notes on the case or minutes of conversations with his client, may also not be seized. In all other cases, under the current legal situation, there is a risk that the materials may be seized, even in the office of the company’s lawyer. From a practical point of view, it is nevertheless advisable to label investigative materials, especially interview protocols and investigation reports, with a notice that they are confidential documents subject to attorney-client privilege and to store them not at the company’s premises but in an attorney’s office.

As outlined above, all employees generally have the right to know whether and what personal data is being or has been processed about them (article 8 paragraph 1, Swiss Federal Act on Data Protection; article 328b, Swiss Code of Obligations).

The employer may refuse, restrict or postpone the disclosure or inspection of internal investigation documents if a legal statute so provides, if such action is necessary because of overriding third-party interests (article 9 paragraph 1, Swiss Federal Act on Data Protection) or if the request for information is manifestly unfounded or malicious. Furthermore, a restriction is possible if overriding the self-interests of the responsible company requires such a measure and it also does not disclose the personal data to third parties. The employer or responsible party must justify its decision (article 9 paragraph 5, Swiss Federal Act on Data Protection).[1]

The scope of the disclosure of information must, therefore, be determined by carefully weighing the interests of all parties involved in the internal investigation.

Depending on the results of the investigation, different steps may have to be taken by the employer. Specifically, the following should be considered:

• in certain cases, there may be an obligation (or at least good reason) to share the results of the workplace investigation with the authorities (see question 25);
• filing of a criminal complaint against the employee;
• disciplinary measures against the employee such as a warning, ordinary termination or termination for cause;
• assessing and asserting claims for damages against the employee;
• offering compliance training to the relevant employees or introducing additional measures to prevent further violations;
• if there is a risk that the company itself is exposed to investigative proceedings at some point and may have to defend itself, investigation materials should be stored at the company's external attorney's office; and
• depending on the individual circumstances of the case and to mitigate potential reputational damage, proactively informing the public (eg, by issuing a press release) may be beneficial.

If the investigation uncovers misconduct, the question arises as to what steps should be taken. Of course, the severity of the misconduct and the damage caused play a significant role. Furthermore, it must be noted that the cooperation of the employee concerned may be of decisive importance for the outcome of the investigation. The possibilities are numerous, ranging, for example, from preventive measures to criminal complaints.[1]

If individual disciplinary actions are necessary, these may range from warnings to ordinary or immediate termination of employment.
