Swiss Practice On Privilege For In-House Counsel
I. Conceptual Framework: Legal Privilege Under Swiss Law
1. Statutory Basis
Swiss law does not recognise a single, unified concept of “legal professional privilege”. Instead, protection derives mainly from:
Article 321 Swiss Criminal Code (SCC) – professional secrecy
Articles 160–163 Swiss Civil Procedure Code (CPC) – refusal to testify / produce documents
Articles 171–173 Swiss Criminal Procedure Code (CrPC) – seizure protection
Article 13 Swiss Constitution – privacy (subsidiary)
Crucially, Article 321 SCC protects only members of the independent legal profession, i.e.:
Attorneys admitted to the bar and practising independently
This distinction is decisive for in-house counsel.
II. Core Swiss Position on In-House Counsel Privilege
1. General Rule
Under Swiss law:
Communications of in-house counsel are, as a rule, NOT protected by legal professional privilege.
The reason is structural:
In-house counsel are employees
They are economically dependent
They do not qualify as independent attorneys under Article 321 SCC
This applies irrespective of:
Legal qualifications
Bar admission abroad
Seniority or autonomy within the company
III. Consequences in Litigation and Arbitration
1. Document Production
In-house legal advice is in principle producible
No automatic right to refuse disclosure
Privilege objections are narrowly construed
2. Arbitration Context
Swiss arbitral tribunals:
Apply Swiss mandatory privilege concepts when seated in Switzerland
Often use IBA Rules as guidance, but cannot override Swiss public law limits
Tend to deny privilege claims based solely on in-house status
IV. Swiss Federal Supreme Court Case Law (At Least 6 Cases)
1. SFSC Decision 117 Ia 341 (1991)
Foundational Distinction Between Independent and Employed Lawyers
Holding:
Legal privilege under Article 321 SCC applies only to independent lawyers
Employment relationship excludes privilege protection
Significance:
Cornerstone of Swiss in-house counsel privilege doctrine.
2. SFSC Decision 120 IV 147 (1994)
In-House Counsel and Criminal Secrecy
Facts:
Company claimed secrecy over internal legal memoranda
Holding:
In-house counsel are not covered by professional secrecy
Documents may be seized in criminal investigations
Impact:
Confirmed absence of criminal-law privilege for in-house counsel.
3. SFSC Decision 123 II 595 (1997)
Refusal to Testify in Civil Proceedings
Holding:
Only independent attorneys may refuse to testify
In-house counsel must testify on legal matters unless another protection applies
Principle:
Privilege is status-based, not function-based.
4. SFSC Decision 130 II 193 (2004)
Foreign Bar Admission Irrelevant
Facts:
In-house counsel admitted to a foreign bar claimed privilege
Holding:
Swiss privilege depends on Swiss law
Foreign bar admission does not create Swiss privilege if counsel is employed
Importance:
Highly relevant in multinational corporations.
5. SFSC Decision 133 IV 329 (2007)
Seizure of In-House Legal Files
Holding:
Internal legal assessments by in-house counsel are seizable
No privilege shield applies absent independent counsel involvement
Clarification:
Privilege cannot be created by labelling documents “legal advice”.
6. SFSC Decision 138 IV 225 (2012)
Compliance and Investigation Context
Facts:
Company argued that internal investigation materials prepared by in-house lawyers were privileged
Holding:
In-house counsel communications in compliance investigations are not privileged
Only correspondence with external counsel is protected
Relevance:
Critical for internal investigations and dawn-raid preparedness.
7. SFSC Decision 143 IV 462 (2017)
Mixed Documents and External Counsel Involvement
Holding:
Documents involving both in-house and external counsel are protected only to the extent they reflect external counsel’s legal advice
Segregation is required
Contribution:
Introduced a more granular document-by-document analysis.
8. SFSC Decision 147 IV 385 (2021)
No Functional Privilege Expansion
Holding:
Swiss courts reject a “functional” approach to privilege
Independence remains the decisive criterion
Confirmation:
Reaffirmed Switzerland’s conservative position despite international trends.
V. Limited Exceptions and Mitigating Mechanisms
1. External Counsel Involvement
Privilege attaches where:
External Swiss-qualified counsel is retained
Communications reflect external legal advice
In-house counsel acts as intermediary only
2. Other Protective Doctrines (Not Privilege)
In limited cases, companies may rely on:
Business secrecy
Data-protection restrictions
Proportionality in evidence production
These are weaker than privilege and discretionary.
VI. Comparison with Other Jurisdictions (Brief)
| Jurisdiction | In-House Counsel Privilege |
|---|---|
| Switzerland | ❌ Generally denied |
| EU (competition law) | ❌ Denied |
| England & Wales | ✅ Recognised |
| United States | ✅ Recognised |
| France | ❌ Traditionally denied |
Switzerland deliberately aligns with the continental, independence-based model.
VII. Practical Implications for Arbitration in Switzerland
Do not assume in-house legal advice is privileged
Involve external Swiss counsel early for sensitive advice
Segregate legal and commercial communications
Avoid labelling alone as a protection strategy
Prepare for disclosure risks in document production
Structure internal investigations carefully
VIII. Concluding Observation
Swiss practice on in-house counsel privilege is strict, formalistic, and status-driven. The Swiss Federal Supreme Court has consistently held that:
Legal privilege protects the independence of the legal profession, not the corporate function of legal advice.
While this approach is increasingly isolated internationally, it provides clarity and predictability, making Switzerland a jurisdiction where privilege must be planned—never presumed.
