Inquiry and Fact-Finding in International Law

Meaning of Inquiry and Fact-Finding

Inquiry and fact-finding are peaceful techniques used in international dispute settlement to establish and clarify the facts underlying a dispute.

International disputes often arise not only because States disagree about the law, but also because they disagree about what actually happened.

An inquiry mechanism provides an impartial process through which a third party, commission or other designated body examines the available evidence and determines or clarifies the relevant facts.

In simple terms:

Inquiry and Fact-Finding = Impartial investigation to establish disputed facts.

The primary objective is not to impose a legal settlement, but to establish a reliable factual basis on which the parties can negotiate or use another dispute-settlement mechanism.

Inquiry under the UN Charter

Article 33(1) of the UN Charter expressly recognises “enquiry” as one of the peaceful means of international dispute settlement.

The provision lists:

• negotiation;
• enquiry;
• mediation;
• conciliation;
• arbitration;
• judicial settlement;
• resort to regional agencies or arrangements.

The term “enquiry” is commonly understood in the context of international dispute settlement as an impartial process for investigating disputed facts.

Why Fact-Finding Is Important

A dispute may continue because the parties have completely different accounts of an incident.

For example:

State A: “State B violated our territorial waters.”

State B: “Our vessels never entered those waters.”

Before the parties can meaningfully discuss the legal consequences, they may need to establish:

• where the vessels actually travelled;
• what happened;
• when the incident occurred;
• who was involved;
• what evidence exists.

Fact-finding attempts to answer these factual questions.

Essential Features

Impartial Investigation

The investigation is conducted by a body or persons expected to examine the facts objectively.

Focus on Facts

The principal concern is establishing what happened, rather than determining the ultimate legal rights and obligations of the parties.

Third-Party Involvement

Fact-finding normally involves an independent commission, panel, organisation or other designated body.

Evidence-Based Process

The investigators may examine:

• documents;
• official records;
• witness statements;
• photographs;
• maps;
• technical material;
• expert evidence;
• other relevant information.

Non-Adjudicatory Character

A fact-finding commission does not ordinarily function as a court.

Its primary role is to establish or clarify facts rather than issue a binding judgment.

Functions of Inquiry and Fact-Finding

Establishing Facts

The central function is to determine the factual circumstances surrounding a dispute.

Resolving Conflicting Accounts

Where parties provide different versions of events, an independent inquiry can assess the competing accounts.

Clarifying Technical Issues

Fact-finding can be especially useful where disputes involve technical questions concerning:

• boundaries;
• maritime incidents;
• environmental damage;
• aviation incidents;
• military activities;
• natural resources.

Creating a Common Factual Record

An impartial investigation can give both parties a common factual basis for subsequent negotiations.

Preventing Escalation

Establishing facts at an early stage can prevent misunderstandings from developing into larger diplomatic or military disputes.

Procedure of Inquiry

The precise procedure depends upon the treaty, agreement or institution under which the inquiry is conducted.

A typical process may involve:

Dispute or factual disagreement

↓

Inquiry mechanism established

↓

Commission / fact-finding body constituted

↓

Terms of reference determined

↓

Evidence collected

↓

Parties heard

↓

Documents and technical material examined

↓

Facts assessed

↓

Findings or report prepared

↓

Parties use findings for settlement

Terms of Reference

An inquiry commission normally operates within defined terms of reference.

These determine:

• what events are to be investigated;
• the questions to be answered;
• the geographical or temporal scope;
• the evidence that may be considered;
• the form of the final report.

A clearly defined mandate helps prevent the inquiry from turning into an unrestricted investigation.

Evidence and Investigation

A fact-finding body may use different sources of evidence depending upon its mandate.

These may include:

Documentary evidence

Official correspondence, reports, records and agreements.

Witness evidence

Statements from persons who have direct knowledge of events.

Expert evidence

Scientific, technical or specialist assessments.

Physical evidence

Photographs, maps, recordings and other material.

On-site investigation

Where appropriate and authorised, investigators may inspect the relevant location.

Fact-Finding Does Not Normally Decide Legal Responsibility

This distinction is extremely important.

Suppose a commission determines:

“The vessel entered the disputed maritime area at 10:30 p.m.”

That is a factual finding.

Whether entering that area constituted an internationally wrongful act is a separate legal question.

Therefore:

Fact-finding → What happened?

Legal determination → What are the legal consequences?

A particular treaty or mandate can, however, give an inquiry body a broader role. The exact powers of the body must therefore be examined from the instrument establishing it.

Inquiry vs Conciliation

Inquiry and conciliation are closely connected but perform different primary functions.

Inquiry / Fact-Finding	Conciliation
Primarily establishes facts	Investigates and seeks settlement
Focuses on factual questions	Examines factual, legal and practical issues
May produce factual findings	Usually produces settlement recommendations
Does not normally determine legal responsibility	May consider legal positions
More limited function	Broader dispute-settlement function

Easy Memory Trick

Inquiry → Facts

Conciliation → Facts + Evaluation + Recommendation

Inquiry vs Negotiation

Negotiation involves direct discussions between the parties.

Inquiry involves an independent investigation into disputed facts.

Negotiation asks:

“What solution can we agree upon?”

Inquiry asks:

“What actually happened?”

Inquiry vs Mediation

Mediation focuses on helping parties reach an agreement.

Fact-finding focuses on establishing the factual circumstances.

A mediator may suggest compromises.

A fact-finding commission ordinarily provides factual findings instead.

Inquiry vs Arbitration

Arbitration involves a tribunal determining the dispute and generally issuing a binding award.

An inquiry commission ordinarily does not impose a binding settlement.

Inquiry → Establishes facts

Arbitration → Decides dispute

Inquiry vs Judicial Settlement

An international court may determine:

• facts;
• applicable law;
• responsibility;
• legal consequences.

An inquiry mechanism normally has a narrower mandate focused principally on facts.

Thus:

Inquiry = fact-finding

Judicial settlement = fact + law + binding judgment

Inquiry and Good Offices

Good offices primarily facilitates communication between disputing parties.

Inquiry is different because it requires investigation of factual issues.

A third State or international organisation could, however, use several techniques together.

For example:

Good offices → communication restored

↓

Inquiry → disputed facts established

↓

Negotiation → settlement discussed

Inquiry and Mediation Can Work Together

Fact-finding may also support mediation.

For example:

Dispute

↓

Fact-finding investigation

↓

Common factual understanding

↓

Mediation

↓

Settlement

This can make mediation more effective because the parties are negotiating from a clearer factual foundation.

International Commissions of Inquiry

International law has a long history of using commissions of inquiry to investigate disputed incidents.

Such commissions may be established:

• by agreement between States;
• under a treaty;
• by an international organisation;
• through an international institution’s mandate;
• as part of a broader peace process.

Their exact powers depend upon the instrument establishing them.

Hague Convention and Commissions of Inquiry

The Hague Convention of 1907 for the Pacific Settlement of International Disputes contains provisions concerning International Commissions of Inquiry.

The Convention provides a framework under which commissions can be used to facilitate the solution of international disputes by elucidating questions of fact through impartial investigation.

This is an important historical foundation for the modern use of international fact-finding.

Commissions of Inquiry and Technical Disputes

Fact-finding is especially useful where a dispute involves technical questions that political negotiators may find difficult to resolve.

Examples include:

• environmental incidents;
• maritime collisions;
• boundary incidents;
• aviation accidents;
• scientific disputes;
• resource-related incidents.

Independent experts can help establish facts that would otherwise remain contested.

Fact-Finding and International Organisations

International organisations may establish or support fact-finding mechanisms.

Such mechanisms can be used to:

• investigate allegations;
• establish factual circumstances;
• provide reports;
• support peaceful settlement;
• assist decision-making by the organisation.

The legal effect of the resulting report depends on the mandate given to the investigating body.

Reports of Fact-Finding Bodies

The final product may be:

• a report;
• factual findings;
• recommendations;
• an assessment of evidence.

A report does not automatically become a binding legal judgment.

Its authority depends upon:

• the legal instrument establishing the body;
• the parties’ agreement;
• the mandate;
• the relevant institutional framework.

Importance of Impartiality

The credibility of fact-finding depends heavily upon independence and impartiality.

If one party believes that the investigators are biased, the findings may fail to resolve the dispute.

Therefore, important considerations include:

• independence of investigators;
• transparent methodology;
• fair treatment of parties;
• reliable evidence;
• clearly defined mandate.

Confidentiality and Fact-Finding

Depending upon the applicable procedure, investigations may involve confidential evidence or communications.

Confidentiality can encourage parties and witnesses to provide information without immediate political or diplomatic pressure.

However, the degree of confidentiality depends on the relevant legal framework.

Advantages of Inquiry and Fact-Finding

Objective Factual Record

An independent body can provide a common factual basis.

Reduces Misunderstanding

It can correct competing or inaccurate accounts of events.

Prevents Escalation

Clarifying facts may reduce tensions before they develop into a larger dispute.

Supports Negotiation

Once facts are established, parties can negotiate more effectively.

Supports Other Mechanisms

Fact-finding can assist mediation, conciliation, arbitration or judicial proceedings.

Useful for Technical Disputes

Experts can address questions that require specialised knowledge.

Limitations

Limited Mandate

A fact-finding body can normally investigate only matters falling within its terms of reference.

No Automatic Settlement

Establishing facts does not necessarily resolve the underlying dispute.

Disagreement Over Evidence

Parties may continue to challenge the interpretation or reliability of evidence.

No Automatic Binding Effect

The findings may not be legally binding unless the relevant instrument provides otherwise.

Political Resistance

States may refuse cooperation or challenge findings they consider unfavourable.

Relationship with Peaceful Settlement

Fact-finding should not be viewed as competing with other peaceful methods.

It can operate as a preparatory or supporting mechanism.

For example:

Inquiry

→ establishes facts

Negotiation

→ parties discuss settlement

Mediation

→ third party facilitates compromise

Conciliation

→ commission evaluates and recommends

Arbitration / Judicial Settlement

→ binding determination

Important Distinction: Inquiry vs Investigation

The terms inquiry and fact-finding are often used in overlapping ways.

“Investigation” is a broad term referring to the process of examining evidence and circumstances.

“Fact-finding” emphasises the objective of establishing factual circumstances.

“Inquiry” is commonly used for an organised or formal examination undertaken by a designated body.

The exact meaning depends on the legal instrument and context.

Important Legal Frameworks

UN Charter

Article 33(1) recognises enquiry as a peaceful means of dispute settlement.

Hague Convention 1907

Provides a framework for International Commissions of Inquiry.

Treaty-Based Mechanisms

Individual treaties may establish their own fact-finding or inquiry procedures.

The powers, procedure and legal effect of each mechanism depend upon the relevant treaty.

Key Exam Points

• Inquiry and fact-finding are peaceful techniques for establishing disputed facts.
• Article 33(1) of the UN Charter expressly recognises enquiry as a peaceful means of dispute settlement.
• A fact-finding body generally investigates what happened, rather than deciding the ultimate legal responsibility of a State.
• The process may involve documents, witnesses, experts, technical evidence and other relevant material.
• The Hague Convention of 1907 provides an important historical framework for International Commissions of Inquiry.
• Fact-finding can provide the factual basis for negotiation, mediation or conciliation.
• A fact-finding report is not automatically a binding judicial decision.
• The exact legal effect depends upon the mandate and instrument establishing the inquiry.
• The central distinction is:

Inquiry → Establishes facts

Conciliation → Investigates + evaluates + recommends

Arbitration → Decides through binding award

Judicial Settlement → Court decides through binding judgment

Conclusion

Inquiry and fact-finding play an important supporting role in the peaceful settlement of international disputes. Many disputes cannot be effectively resolved until the parties have a reasonably reliable understanding of what actually occurred.

By providing an impartial investigation and factual record, inquiry can reduce misunderstandings, support negotiations and facilitate more advanced forms of dispute settlement.

The key formula to remember is:

Inquiry and Fact-Finding = Impartial Investigation → Establishment of Facts → Factual Basis for Peaceful Settlement
