Art. 163 CPC from 2023
Art. 163 The Parties' Right to Refuse Right to refuse
1 A party may refuse to cooperate if:a. the taking of evidence would expose a close associate as defined in Article 165 to criminal prosecution or civil liability;b. the disclosure of a secret would be an offence under Article 321 of the Swiss Criminal Code (SCC) (1) ; the foregoing does not apply to auditors; Article 166 paragraph 1 letter b third subset applies by analogy.
2 Other confidants entrusted with legally protected secrets may refuse to cooperate if they credibly demonstrate that the interest in keeping the secret outweighs the interest in finding the truth.
