1. Meaning and Nature of Mediation Cost Disputes

A mediation cost dispute arises when parties disagree about:

• Mediator’s fees or institutional charges
• Administrative expenses of mediation centres
• Allocation of costs between parties
• Additional expenses like travel, expert consultation, or session extensions
• Refund or non-refund of court fees after settlement
• Unilateral or excessive fee demands by mediators or institutions

Unlike litigation costs, mediation costs are generally contractual or policy-driven, not strictly fixed by statute, which often leads to disagreements.

2. Core Legal Principles Governing Mediation Costs

(A) Party Autonomy

Courts consistently hold that ADR processes depend heavily on party autonomy, meaning:

• Parties can agree on how costs are shared
• No mediator can unilaterally impose arbitrary costs

This principle is strongly supported in arbitration jurisprudence and is applied analogously in mediation contexts.

(B) Equality in Cost Sharing (Default Rule)

In most institutional mediation systems:

• Costs are split equally unless agreed otherwise
• This ensures neutrality and prevents dominance by the financially stronger party

(C) Institutional Fee Structures

Many mediation centres (e.g., court-annexed mediation centres, private ADR institutions) follow:

• Fixed slabs based on claim value
• Session-based mediator fees
• Administrative charges

For example, Indian ADR institutions prescribe structured mediator/session fees depending on dispute value.

(D) Court Fee Refund Issues

A major “cost dispute” arises after settlement:

• Lok Adalats often give full court fee refund
• Mediation generally does not automatically guarantee full refund

The Supreme Court has clarified that mediation and Lok Adalat are distinct mechanisms and cannot be treated identically for refund purposes.

3. Common Types of Mediation Cost Disputes

1. Excessive mediator fees after settlement
2. Unclear fee escalation during proceedings
3. Dispute over number of sessions billed
4. Refusal to refund administrative charges after failure
5. Conflict over who pays institutional mediation costs
6. Lawyer vs client disputes over mediation negotiation fees

4. Important Case Laws on Mediation Cost Disputes (India & ADR Principles)

1. Oil and Natural Gas Corporation Ltd. v. Afcons Gunanusa JV (Supreme Court)

• Principle: Arbitrators cannot unilaterally fix or increase fees; party autonomy is essential.
• Relevance to mediation: The same reasoning applies—mediators or institutions cannot impose arbitrary cost escalation without agreement.
• Key takeaway: ADR costs must be transparent and mutually accepted.

2. Sanjeev Kumar Harakchand Kankariya v. Union of India (Supreme Court, 2024)

• Issue: Refund of court fees in ADR settlements
• Held: Lok Adalat and mediation are distinct; mediation does not automatically entitle parties to full refund of court fees. 
• Relevance: Cost expectations in mediation must be understood separately from litigation incentives.

3. Afcons Infrastructure Ltd. v. Cherian Varkey Construction Co. (Supreme Court, 2010)

• Principle: Courts should actively refer disputes to ADR including mediation under Section 89 CPC
• Cost relevance: ADR is meant to reduce litigation costs; however, courts did not guarantee uniform cost structures, leading to variability and disputes.

4. Salem Advocate Bar Association v. Union of India (Supreme Court, 2005)

• Principle: Strengthened Section 89 CPC and ADR mechanisms
• Cost relevance: Recognized need for structured ADR processes to reduce litigation expenses but left cost regulation largely to rules/institutions
• Impact: This flexibility later led to fee-related inconsistencies in mediation practice.

5. M.R. Krishna Murthi v. New India Assurance Co. Ltd. (Supreme Court, 2019)

• Principle: Promoted institutional mediation frameworks and ADR centres
• Cost relevance: Emphasized strengthening mediation infrastructure but highlighted need for proper institutional regulation of ADR costs
• Issue: Without uniform fee regulation, parties may face unpredictable expenses.

6. Indian Bank v. ABS Marine Products (Supreme Court, 2006)

• Principle: ADR settlements must reflect mutual consent and fairness
• Cost relevance: Any monetary term (including costs) must be voluntarily agreed upon
• Relevance: Prevents unilateral imposition of mediation-related financial burdens.

7. State of Maharashtra v. Hindustan Construction Co. Ltd. (Supreme Court, 2019)

• Principle: Courts emphasize efficiency and cost reduction in dispute resolution
• Cost relevance: Reinforces ADR as a cost-saving mechanism, but disputes arise when costs exceed expectations or contractual terms.

5. Key Judicial Observations on Cost Issues in ADR

Courts generally emphasize:

• No unilateral fee fixation
• Reasonable and transparent cost structures
• Party consent is essential
• ADR is meant to reduce litigation burden, not create financial shock

However, courts also recognize:

• Lack of uniform mediation fee law in many jurisdictions
• Institutional variation in cost structures
• Potential exploitation risks in private mediation setups

6. Practical Causes of Mediation Cost Disputes

• Absence of uniform statutory fee schedule
• Lack of clarity in mediation agreements
• Power imbalance between parties
• Institutional discretion in setting fees
• Unclear distinction between mediation and arbitration cost principles

7. Conclusion

Mediation cost disputes arise primarily due to the flexible and party-driven nature of mediation, where:

• Costs are not rigidly fixed by statute
• Institutions and mediators rely on agreements or internal rules
• Courts intervene only when fees become arbitrary or unjustified

Judicial trends clearly show that while mediation is encouraged as a low-cost dispute resolution method, courts strongly protect parties from unilateral or excessive cost impositions.
