Algorithmic Account Exclusion Without Due Process in Switzerland (Detailed Legal Explanation + Case Law)

1. Conceptual Framework (Swiss Law Context)

“Algorithmic account exclusion without due process” refers to situations where:

• A platform (bank, social media, fintech, marketplace, etc.) uses automated systems or algorithms to suspend or terminate user access, and
• The affected user is not given meaningful notice, explanation, or opportunity to challenge the decision.

In Switzerland, this issue is not governed by a single “AI law” but is assessed through:

• Swiss Federal Constitution (BV) – fundamental rights (equality, legality, prohibition of arbitrariness)
• Swiss Code of Obligations (CO) – contractual good faith
• Federal Act on Data Protection (FADP) – automated decision-making transparency
• Sectoral regulations (banking, telecom, platform governance)

Swiss law generally does not prohibit automated decisions, but it does require legal justification and procedural fairness when rights are significantly affected.

2. Core Legal Problem: Is “Due Process” Required for Private Algorithmic Exclusion?

In Switzerland, due process obligations depend on whether:

1. The actor is a state authority (full constitutional due process applies), OR
2. A private platform (contract law + fundamental rights apply indirectly)

For private platforms:

• No full constitutional “right to hearing” applies automatically
• But courts enforce:
  • good faith principle (Art. 2 CO)
  • abuse of rights doctrine
  • minimum transparency obligations
  • contractual fairness standards

3. Relevant Swiss Case Law (Key Judgments)

Below are 6 important Swiss jurisprudential decisions / principles relevant to algorithmic exclusion, due process, and automated decision systems.

Case 1: Swiss Federal Supreme Court (Internal Investigations – Due Process Limits)

Case: 4A_368/2023 (Bank employee dismissal context)

Holding:

The Court held that:

• Criminal procedural guarantees do NOT apply in private internal investigations
• However, basic fairness principles still apply when outcomes affect employment rights

Relevance:

Even in private algorithmic or investigative contexts:

• Full due process is not required
• But minimum fairness standards still bind employers/platforms

Case 2: Swiss Federal Supreme Court – Sanctions Compliance Case (4A_659/2020)

Holding:

A Swiss bank could refuse execution of client instructions due to:

• External legal risk (OFAC sanctions)
• Contractual clauses allowing refusal for legal compliance

Principle:

Private entities may exclude access without liability if justified by legal/compliance necessity

Relevance:

Algorithmic exclusion (e.g., fraud detection systems) is valid if:

• Contractually grounded
• Legally justified
• Not arbitrary

Case 3: Federal Supreme Court – Domain Blocking (Gespa Gambling Case, 2C_62/2025)

Holding:

• Domain blocking by regulators was upheld
• Court emphasized formal admissibility and legal basis review
• Automated or administrative blocking must still meet:
  • statutory authorization
  • proportionality

Relevance:

Even automated blocking systems must satisfy:

• Legal basis requirement
• Proportionality principle (Art. 5 BV)

Case 4: Federal Administrative Court – AI Cannot Be Inventor (B-2532/2024)

Holding:

• AI systems cannot be legally recognized as inventors
• Only natural persons qualify under patent law

Principle:

Swiss law attributes legal responsibility only to humans or legal entities

Relevance:

Algorithmic exclusion decisions:

• Must be attributable to a legal entity (company, bank, platform)
• AI cannot be a legally independent decision-maker

Case 5: Constitutional Principle – Non-Discrimination in Algorithmic Systems

Legal Basis:

• Swiss Federal Constitution (Art. 8 BV)
• Applied in private law via indirect horizontal effect

Doctrine:

Algorithmic systems must not produce:

• arbitrary exclusion
• discriminatory outcomes

Even if no specific AI law exists:

• discrimination via automated systems can be challenged

Relevance:

If account exclusion is algorithmic and biased:

• it may violate constitutional equality principles indirectly

Case 6: Swiss Federal Supreme Court – Contractual Platform Rights (General Principle)

Principle from multiple rulings:

Platforms may terminate accounts if:

• Terms of Service clearly permit termination
• Decision is not abusive or arbitrary
• Good faith principle is respected

Relevance:

This is the main legal basis for algorithmic account exclusion in Switzerland.

Key constraints:

• Must not be purely arbitrary
• Must be justifiable under contract law
• Must allow dispute mechanisms in complex cases

4. Procedural Due Process Standards in Switzerland (Applied to Algorithms)

Even without explicit AI regulation, Swiss law implies minimum safeguards:

A. Transparency requirement

Users must generally be informed:

• why account was restricted
• what rule was violated

B. Contractual justification

Platform must rely on:

• Terms of Service
• Legitimate business interest

C. Proportionality principle

Exclusion must be:

• necessary
• not excessive
• reversible where appropriate

D. No fully “black box” irreversible exclusion

Courts increasingly expect:

• some form of appeal or review mechanism

5. Key Legal Tension: “Automation vs Due Process”

Swiss law currently allows:

• Algorithmic detection (fraud, AML, moderation)
• Automated triggers for suspension

But restricts:

• Fully opaque decisions without explanation
• Arbitrary or discriminatory exclusions
• Lack of any contestation mechanism in serious impacts (banking, employment, essential services)

6. Conclusion

In Switzerland, algorithmic account exclusion without due process is not automatically illegal, but it becomes unlawful when it violates:

• Good faith principle (Art. 2 CO)
• Non-discrimination (Art. 8 BV)
• Proportionality (Art. 5 BV)
• Contractual transparency obligations

Swiss courts consistently maintain a balanced model:

• No strict US-style constitutional due process in private platforms
• But strong enforcement of fairness, proportionality, and accountability
