1. Duchy Farm Kennels Ltd v Steels (UK High Court, 2020)

This is one of the most cited modern cases on settlement confidentiality clauses.

Facts

• Parties entered a settlement (COT3 agreement).
• It included a strict confidentiality clause.
• The employee allegedly disclosed the settlement to a third party.
• Employer stopped payments claiming repudiatory breach.

Issue

Whether breach of confidentiality automatically allows the other party to terminate the settlement and stop payment.

Held

• The court held the confidentiality clause was an “intermediate term”, not a fundamental condition.
• Not every breach allows termination.
• The breach must be serious enough to destroy the contract’s purpose.

Key Principle

Confidentiality clauses are often overestimated in importance. Minor disclosure does not automatically void settlement.

Importance

Shows that confidentiality clauses have limited “termination power” unless clearly drafted as essential conditions.

2. Jan Wong v The Globe and Mail Inc (Ontario Divisional Court, 2014)

Facts

• Journalist settled employment dispute.
• Settlement included confidentiality obligations.
• She posted online comments referencing the dispute.

Issue

Whether breach of confidentiality justified withholding settlement benefits.

Held

• Court considered whether breach was material or minor.
• Employer’s refusal to pay was not automatically justified.
• Remedies depend on actual damage caused by disclosure.

Key Principle

A confidentiality breach must be material and harmful, not merely technical, to justify serious consequences.

Importance

Confidentiality clauses are enforced, but courts require proportionality in remedy.

3. Perry Kansagra v Smriti Madan Kansagra (Supreme Court of India, 2019)

Facts

• Family dispute resolved through mediation.
• Settlement included confidentiality obligations.
• One party disclosed mediation details in later proceedings.

Issue

Whether mediation confidentiality bars disclosure in court.

Held

• Mediation confidentiality is strong, but not absolute.
• Courts may permit disclosure when:
  • required for enforcement
  • necessary for justice
  • in child welfare or public interest contexts

Key Principle

Confidentiality in settlements/mediation is subject to exceptions for justice and enforcement.

Importance

Confirms that confidentiality cannot be used to block access to justice or enforcement proceedings.

4. Haresh Dayaram Thakur v State of Maharashtra (Supreme Court of India, 2000)

Facts

• Concerned conciliation proceedings under arbitration framework.
• Included confidentiality of settlement discussions and agreement.

Issue

Whether confidentiality is absolute in conciliation settlements.

Held

• Confidentiality is a core feature of conciliation.
• However, disclosure is permitted when necessary for:
  • enforcement
  • legal proceedings
  • statutory requirements

Key Principle

Settlement confidentiality exists, but cannot override legal process requirements.

Importance

Establishes statutory limit: confidentiality must yield to legal necessity.

5. National Engineering Industries Ltd v State of Rajasthan (Supreme Court of India, 1999)

Facts

• Industrial settlement agreement between employer and union.
• Dispute arose regarding enforcement of settlement terms.

Issue

Whether settlement clauses (including confidentiality-type obligations) can restrict later legal claims.

Held

• Settlement agreements are binding contracts.
• However, clauses cannot override:
  • statutory labour rights
  • public policy protections

Key Principle

Settlement terms are enforceable, but cannot contract out of statutory protections.

Importance

Confidentiality clauses cannot be used to:

• suppress statutory rights
• prevent lawful claims under labour law

6. Afcons Infrastructure Ltd v Cherian Varkey Construction (Supreme Court of India, 2010)

Facts

• Case dealt with ADR mechanisms including settlement and mediation.
• Discussed settlement confidentiality in ADR frameworks.

Issue

Role and limits of confidentiality in court-referred settlements.

Held

• ADR confidentiality is important for dispute resolution.
• But court supervision ensures:
  • fairness
  • legality
  • enforceability

Key Principle

Confidentiality supports ADR, but courts retain supervisory control.

Importance

Confidentiality is a procedural protection, not a substantive legal shield.

7. Damodar Valley Corporation v K.K. Kar (Supreme Court of India, 1973)

Facts

• Arbitration/settlement dispute involving contract termination and settlement terms.

Issue

Whether settlement-related clauses affect arbitration rights and enforcement.

Held

• Settlement does not automatically extinguish dispute resolution rights unless clearly stated.
• Contract interpretation governs whether rights survive.

Key Principle

Settlement clauses (including confidentiality-linked ones) must be clearly drafted to have extreme effects like waiver or termination of rights.

Importance

Confidentiality clauses alone rarely extinguish broader legal rights.

Core Legal Limits on Settlement Confidentiality Clauses

Across these cases, courts consistently enforce four major limits:

1. Public Policy Limit

Confidentiality cannot:

• conceal illegality
• prevent reporting to regulators
• obstruct justice

2. Statutory Override

Laws (labour, whistleblowing, criminal reporting) override confidentiality.

3. Proportionality Rule

Minor breaches ≠ automatic termination or heavy penalties.

4. Drafting Clarity Requirement

If parties want strict consequences, clauses must clearly state:

• confidentiality is a condition precedent
• breach allows termination or clawback

Final Understanding (Simplified)

A settlement confidentiality clause:

• is enforceable as a contract term
• but is not absolute secrecy
• courts treat it as context-dependent
• and enforce it only when breach is material and harmful
