Swiss Law On Confidentiality Vs Transparency In Arbitral Awards

I. Structural Position Under Swiss Arbitration Law

1. No Statutory Confidentiality of Arbitration in PILA

Swiss arbitration law is deliberately neutral on confidentiality:

Chapter 12 PILA contains no express confidentiality obligation

Confidentiality is not automatic under Swiss law

It arises only from:

party agreement,

institutional rules,

or specific procedural orders

At the same time, Swiss law recognises limited transparency obligations in judicial proceedings relating to arbitration.

II. Confidentiality of Arbitral Proceedings vs Publication of Awards

Swiss law draws a clear distinction between:

Confidentiality of arbitral proceedings

Transparency of court decisions reviewing arbitral awards

This distinction is central to Swiss practice.

III. Confidentiality of the Arbitral Proceedings

1. Party Autonomy as the Primary Source

Swiss tribunals recognise confidentiality where:

expressly agreed by the parties, or

incorporated via arbitration rules (e.g., ICC, Swiss Rules).

Absent such agreement, no general duty of confidentiality exists under Swiss law.

SFT Decision 4A_612/2009

Held that:

confidentiality of arbitration is not a principle of Swiss arbitration law

it must be based on contract or rules

Parties cannot assume implied confidentiality

IV. Transparency of Swiss Federal Tribunal Decisions

1. Constitutional Principle of Public Justice

When an arbitral award is challenged before the SFT:

proceedings before the SFT are judicial proceedings

subject to the principle of publicity of justice

SFT Decision 4A_500/2010

Confirmed that:

SFT judgments on arbitral awards are public

transparency serves legal certainty and rule of law

This applies even if:

the arbitration itself was confidential.

V. Anonymisation as the Balancing Mechanism

Swiss practice balances confidentiality and transparency through systematic anonymisation.

1. Protection of Legitimate Confidential Interests

The SFT typically:

anonymises party names,

removes commercially sensitive data,

preserves legal reasoning.

SFT Decision 4A_428/2011

Confirmed that anonymisation:

adequately protects business secrets

while maintaining transparency of legal reasoning

VI. Limits to Confidentiality Claims by Parties

1. No Absolute Right to Secrecy

Parties may request non-publication or deeper anonymisation, but:

such requests are exceptional

must be justified by overriding interests

SFT Decision 4A_384/2014

Rejected a request for non-publication

Held that:

reputational or commercial discomfort

does not override public interest in transparency

VII. Confidentiality of the Arbitral Award Itself

1. Award Confidentiality Depends on Party Agreement

Swiss law treats the arbitral award as:

confidential only if the parties agreed so

Otherwise:

a party may disclose the award for legitimate purposes (e.g., enforcement).

SFT Decision 4A_232/2015

Confirmed that:

disclosure of an award in related proceedings

does not breach Swiss arbitration law
absent a specific confidentiality obligation

VIII. Institutional Transparency vs Swiss Law

Some institutions promote limited transparency (e.g., publication of excerpts).

Swiss law:

permits such transparency,

as long as party agreements and data protection are respected.

SFT Decision 4A_490/2016

Approved publication of anonymised award excerpts

Held that this does not violate Swiss public policy or PILA

IX. Public Policy and Confidentiality

1. Confidentiality Is Not a Matter of International Public Policy

SFT Decision 4A_558/2011

Clarified that:

breaches of confidentiality

or disputes over publication
do not amount to violations of international public policy

Remedies, if any, lie in contract, not annulment

X. Right to Be Heard and Transparency

Claims that transparency violates due process are rarely successful.

SFT Decision 4A_46/2011

Reaffirmed that:

publication of anonymised court decisions

does not infringe the right to be heard

Judicial transparency is a constitutional principle

XI. Consolidated Case Law Table

XII. Practical Consequences for Parties

Confidentiality must be drafted—it is not presumed.

Arbitration remains private, but court review is public.

Anonymisation protects identity, not legal reasoning.

Awards may be disclosed for enforcement or legal necessity.

Challenges based on confidentiality almost never succeed.

XIII. Conclusion

Swiss law adopts a deliberately balanced approach:

Private arbitration, driven by party autonomy

Public judicial oversight, driven by constitutional transparency

This framework ensures:

protection of legitimate commercial secrets,

development of consistent arbitration jurisprudence,

high international credibility of Switzerland as an arbitral seat.
