Conflicts of interest sit at the heart of mediation ethics. The legitimacy of the mediation process depends heavily on the neutrality and impartiality of the mediator. Even the appearance of bias can undermine trust between parties and jeopardise the enforceability or acceptance of any outcome. This raises an essential question: must mediators disclose possible conflicts of interest, and what happens if they fail to do so?
The Duty of Disclosure
Yes—mediators should be expected to disclose any circumstances that might reasonably give rise to doubts about their impartiality or independence. This duty is not limited to actual conflicts; it extends to potential and perceived conflicts as well.
Most professional mediation frameworks and codes of conduct impose an ongoing obligation of disclosure. This means mediators must not only disclose relevant circumstances at the outset but also any that arise during the course of the mediation.
The underlying principle is simple: parties must be able to make an informed decision about whether to proceed with a particular mediator.
What Constitutes a Conflict of Interest?
Conflicts of interest can take many forms, and not all will automatically result in disqualification of the mediator. The key question is whether the circumstance could reasonably be seen as affecting the mediator’s independence.
Common examples include:
1. Prior Involvement with a Party
If a mediator has previously acted for one of the parties—whether as a lawyer, advisor, or consultant—this may raise concerns. The degree of concern will depend on factors such as:
2. Financial Interests
Holding shares or other financial interests in a corporate party—or in an associated company—can create a clear conflict. Even minor shareholdings may need to be disclosed if they could be perceived as influencing the mediator’s independence.
3. Repeat Appointments
A mediator who has previously acted in mediations involving one of the parties or indeed the same lawyers may face scrutiny, particularly if:
In some fields (e.g. shipping law) there is a restricted pool of experienced mediators and therefore it is very difficult to avoid repeat appointments. While repeat appointments are common in practice, transparency is crucial to avoid perceptions of partiality.
4. Personal or Professional Relationships
Relationships with individuals involved in the mediation—such as legal representatives, executives, or witnesses—can also give rise to conflicts. These relationships do not have to be close to warrant disclosure; even indirect connections may be relevant.
5. Indirect or Institutional Connections
Membership in the same organisation, chambers, or firm network may also raise concerns, depending on the circumstances.
When Is Disclosure Enough?
Disclosure does not automatically disqualify a mediator. In many cases, once a potential conflict is disclosed, the parties may agree to proceed regardless.
The key is informed consent. If all parties:
then the mediator can usually proceed.
However, if the conflict is serious—particularly where it creates a real risk of bias— it may well be appropriate for the mediator to decline the appointment and not ask the parties to consent.
Consequences of Failure to Disclose
Failure to disclose a conflict of interest can have serious consequences, both for the mediation process and for the mediator personally.
1. Appointment Set Aside
If a conflict comes to light, the mediator’s appointment may be challenged and potentially set aside. This can disrupt or invalidate the mediation process.
2. Loss of Confidence in the Process
Even if the mediation continues, undisclosed conflicts can erode trust between the parties. This may reduce the likelihood of settlement or lead to disputes over the fairness of the outcome.
3. Liability for Wasted Costs
In extreme cases, a mediator who fails to disclose a material conflict may face claims for wasted costs. This is more likely where:
4. Professional and Reputational Consequences
Mediators are often bound by professional standards and ethical codes. Breach of these obligations can result in:
5. Challenges to Settlement Agreements
While mediation settlements are generally contractual in nature, a serious undisclosed conflict could be used to challenge the validity of an agreement, particularly if it can be shown that the process was fundamentally unfair.
Best Practice for Mediators
To minimise risk, mediators should adopt a cautious and transparent approach:
Conclusion
Disclosure of conflicts of interest is not just a procedural formality—it is central to the integrity of mediation. The standard is not whether the mediator is biased, but whether there is a reasonable perception that he/she might be.
Ultimately, transparency protects everyone involved. It preserves trust in the process, safeguards the enforceability of outcomes, and upholds the mediator’s professional standing. Failure to disclose, by contrast, risks not only the collapse of the mediation but also legal, financial, and reputational consequences that can be difficult to undo.
