Civil Law And UAE Epistemic Limits of Civil Adjudication

1. Introduction

Epistemic limits of civil adjudication means the limits on what a civil court can actually know, establish, reconstruct, and confidently determine from the evidence presented to it.

In UAE civil law, adjudication is not an unrestricted search for absolute truth. The court determines legal rights on the basis of:

• pleadings and admissions;
• documentary evidence;
• electronic evidence;
• witness testimony;
• presumptions;
• expert reports;
• contractual records;
• technical and accounting material;
• the applicable burden of proof; and
• the court's assessment of the evidence.

The modern UAE evidentiary framework is particularly important because Federal Decree-Law No. 35 of 2022 on Evidence regulates proof in civil and commercial transactions, including expert evidence. The legislation expressly permits courts to appoint experts and also regulates their duties and the parties' ability to challenge expert conclusions.

Thus, an epistemic limit does not mean that the UAE court cannot decide a case. It means that the court's decision is necessarily constrained by the legally admissible and sufficiently persuasive evidence available to it.

2. Meaning of Epistemic Limits

The word epistemic concerns knowledge.

In civil adjudication, the court may face questions such as:

What actually happened?

Who caused the damage?

Was the defendant negligent?

What was the true value of the loss?

Was a technical defect caused by design, construction, maintenance, or another factor?

What would have happened if the contractual breach had not occurred?

These questions may have an objective answer in the real world, but the court may not possess perfect information.

The judicial task is therefore to determine the legally provable version of events.

Basic model

Real-world event → evidence → judicial evaluation → established fact → legal characterization → judgment

At every stage information can be incomplete.

3. Epistemic Limits Are Different from Legal Limits

Two different limitations should be distinguished.

A. Legal limitation

The law determines:

• what evidence is admissible;
• who carries the burden of proof;
• how evidence may be challenged;
• when expert evidence may be used;
• what facts may be established by admission;
• procedural time limits.

B. Epistemic limitation

Even when evidence is legally admissible, it may not provide complete knowledge.

For example:

A building collapses.

The court may have:

• engineering reports;
• photographs;
• construction contracts;
• invoices;
• inspection records;
• witness testimony.

But it may still be impossible to determine with absolute certainty whether the principal cause was:

1. defective design;
2. defective materials;
3. construction error;
4. soil movement;
5. inadequate maintenance; or
6. a combination of causes.

The court therefore works with the evidence sufficiently established in the proceedings.

4. Burden of Proof as an Epistemic Allocation Mechanism

One of the most important mechanisms for dealing with uncertainty is the burden of proof.

Instead of requiring the court to discover absolute truth, procedural law allocates responsibility for proving particular facts.

The practical consequence is:

A party asserting a legally significant fact generally has to establish the factual basis necessary for the requested relief.

This prevents civil litigation from becoming an unlimited investigation into every possible explanation.

5. Evidence Determines the Court's Knowledge

The UAE Evidence Law provides a structured framework for establishing facts.

Evidence can include:

• written evidence;
• electronic evidence;
• testimony;
• presumptions;
• admissions;
• inspection;
• expert evidence; and
• other legally recognized forms of proof.

The court therefore does not simply ask:

“What might have happened?”

It asks:

“What has been sufficiently established through legally recognized evidence?”

This distinction is central to epistemic limits.

6. Expert Evidence and the Boundary of Judicial Knowledge

Modern civil disputes frequently involve matters beyond ordinary judicial knowledge.

Examples include:

• engineering;
• accounting;
• valuation;
• banking;
• construction;
• medicine;
• information technology;
• cybersecurity;
• environmental damage;
• financial modelling;
• cryptocurrency;
• artificial intelligence.

The UAE framework expressly recognizes the role of experts in providing technical assistance to judicial authorities. Dubai's expert-witness legislation similarly describes experts as providing technical assistance intended to improve the accuracy of judicial decisions.

But an expert does not become the judge.

The distinction is:

Consequently, expert evidence reduces an epistemic gap without eliminating judicial responsibility.

7. The Court Is Not Automatically Bound by an Expert

An important UAE principle is that an expert report is evidence rather than an automatic judgment.

The court may:

• accept the report;
• reject it;
• partially rely on it;
• request clarification;
• return the matter to the expert;
• appoint another expert where appropriate.

The Federal Evidence Law specifically regulates expert reports and permits judicial consideration of expert work, while also providing mechanisms concerning objections and expert responsibility.

This creates an important epistemic safeguard:

technical expertise informs judicial knowledge, but does not replace judicial reasoning.

8. Case Law on Epistemic Limits of Civil Adjudication

Because “epistemic limits of civil adjudication” is a theoretical description rather than a named UAE cause of action, the following cases are best understood as authorities illustrating particular components of the concept.

Case 1 — UAE Federal Supreme Court, Civil Cassation No. 99 of 1995

The Federal Supreme Court recognized the trial court's authority to evaluate expert evidence and factual material where the reasoning adopted from the expert report provided a sufficient basis for the conclusion.

The Court treated the assessment of factual matters such as fault as belonging substantially to the trial court where supported by adequate reasoning.

Epistemic significance

This illustrates the distinction between:

technical information → judicial evaluation → legal conclusion.

The expert supplies technical knowledge, but the court determines whether that knowledge sufficiently establishes the relevant fact.

Case 2 — UAE Federal Supreme Court, Civil Cassation No. 139 of 1996

The Federal Supreme Court considered documentary material, including invoices, and the role of expert examination in evaluating the underlying records.

The Court emphasized that challenges concerning the trial court's understanding and assessment of factual evidence may amount to disagreement with the trial court's evidentiary evaluation rather than a legal error.

Epistemic significance

The case demonstrates that appellate review does not necessarily recreate the entire factual investigation.

The trial court occupies the principal position for:

• examining evidence;
• weighing competing materials;
• understanding the factual record.

Case 3 — UAE Federal Supreme Court, Cassation No. 34 of Judicial Year 22

The Court criticized a judgment that relied heavily on an expert report without adequately explaining the remaining evidence and without properly establishing all the elements relevant to the criminal and civil claims.

The judgment was therefore vulnerable because the reasoning did not sufficiently identify and evaluate the evidence supporting the conclusion.

Epistemic significance

This is particularly important.

An expert report cannot simply become a black box.

The judgment must explain:

1. what evidence exists;
2. what the evidence establishes;
3. how the evidence supports the conclusion.

Thus, judicial reasoning must remain sufficiently transparent for appellate review.

Case 4 — UAE Commercial Cassation No. 240 of 2021

The Court held that where a court relies on an expert report, it must consider material objections raised by the parties where those objections could affect the outcome.

The failure to address substantial objections to the expert's methodology or findings can constitute a deficiency in reasoning and affect the validity of the judgment.

Epistemic significance

This case illustrates adversarial correction of judicial knowledge.

The court's knowledge is not supposed to be formed from only one informational perspective.

The opposing party can identify:

• missing documents;
• incorrect calculations;
• methodological errors;
• overlooked evidence;
• alternative explanations.

This process reduces epistemic error.

9. Case 5 — Dubai Court of Cassation, Civil Cassation No. 647 of 2021

This case is reported in UAE legal commentary as emphasizing the importance of the court demonstrating that it understood and evaluated material evidence and arguments capable of affecting the outcome.

Epistemic significance

A judgment should not merely announce a result.

It should demonstrate the reasoning process through which the court moved from:

evidence → factual finding → legal conclusion.

This provides a safeguard against arbitrary factual determination.

10. Case 6 — Dubai Court of Cassation, Civil Cassation No. 79 of 2020

The case is reported as concerning the evidentiary consequences of a clear admission.

An admission can significantly reduce the epistemic dispute because the admitted fact does not require the same degree of independent proof.

For example, if receipt of money is admitted, the dispute may shift toward:

• repayment;
• contractual purpose;
• entitlement;
• accounting;
• legal characterization. 

Epistemic significance

An admission operates as an uncertainty-reduction mechanism.

Instead of investigating an already-established fact, the court can concentrate on the remaining disputed questions.

11. Case 7 — Dubai Court of Cassation, Civil Cassation No. 402 of 2020

This case is reported in UAE legal commentary as involving competing expert opinions concerning the cause of a fire.

The significance attributed to the case is that conflicting technical opinions do not automatically establish the claimant's case; the necessary elements of liability still have to be established through the evidence.

Epistemic significance

This demonstrates a fundamental limitation:

multiple expert opinions do not necessarily produce certainty.

Where experts disagree, the court must assess:

• methodology;
• factual assumptions;
• supporting documents;
• technical consistency;
• causation;
• credibility.

The mere existence of an expert report is therefore insufficient.

12. Case 8 — Dubai Court of Cassation, Civil Appeal No. 1202 of 2026

A recent Dubai Court of Cassation decision concerned a compensation claim arising from fire damage. The reported discussion concerned expert evidence, proof of loss and the absence of an automatic entitlement to a supplementary expert report.

Epistemic significance

The case illustrates the distinction between:

proving that an event occurred

and

proving the legally recoverable amount of damage.

For example:

Fire occurred ≠ every claimed financial loss has been established.

The claimant may need separate evidence concerning:

• damaged inventory;
• accounting records;
• valuation;
• causation;
• quantum.

This is an important epistemic boundary in damages litigation.

13. Case 9 — Abu Dhabi Commercial Bank PJSC v NMC Healthcare Ltd [2025] ADGMCFI 0004

The ADGM Courts considered whether expert evidence was reasonably required in complex proceedings.

The court considered the demands of the trial and concluded that the particular expert evidence proposed would not assist the proceedings sufficiently, while identified UAE-law issues could be dealt with through legal submissions.

Epistemic significance

This illustrates that more information is not necessarily better information.

An adjudicator must distinguish between:

• information that genuinely assists factual determination; and
• information that merely increases procedural complexity.

14. Main Categories of Epistemic Limits

A. Historical uncertainty

Civil courts generally decide disputes concerning events that have already occurred.

Documents may have disappeared.

Witness memories may deteriorate.

Electronic records may be incomplete.

Therefore, the court reconstructs past events from available evidence.

B. Causal uncertainty

Causation is particularly difficult where several factors contributed to the loss.

For example:

construction defect + poor maintenance + extreme weather → structural damage

The court may have to determine whether one factor was:

• the sole cause;
• a contributing cause;
• a substantial cause;
• merely a background condition.

C. Quantum uncertainty

A claimant may establish liability but fail to establish the exact amount of recoverable loss.

This is particularly relevant to:

• lost profits;
• future losses;
• business interruption;
• valuation;
• opportunity loss;
• technological assets;
• intellectual property.

D. Technical uncertainty

Courts may lack specialized knowledge concerning:

• engineering;
• AI systems;
• algorithms;
• blockchain;
• financial instruments;
• environmental contamination.

Expert evidence attempts to bridge this gap.

E. Counterfactual uncertainty

Damages frequently require asking:

What would have happened if the defendant had not breached the obligation?

That is inherently hypothetical.

For example:

A business claims that a contractual breach caused AED 10 million in lost profits.

The court may need to determine what the business would actually have earned without the breach.

This requires assumptions concerning:

• market conditions;
• customer behaviour;
• costs;
• competition;
• financing;
• future demand.

The court therefore cannot obtain perfect historical certainty about an unrealized future.

15. Epistemic Limits in AI-Related Civil Litigation

The problem becomes particularly significant with artificial intelligence.

Suppose an AI system makes a decision that causes financial damage.

Questions may include:

• Who designed the model?
• Who trained it?
• What data was used?
• Was the data defective?
• Was the algorithm changed?
• Who approved deployment?
• Was human supervision adequate?
• Can the output be technically reconstructed?
• Can causation be demonstrated?

An expert may explain the technology, but the court must ultimately determine legal responsibility.

This produces a three-level structure:

Algorithmic fact → technical interpretation → legal attribution

The court should not treat an algorithmic output as automatically equivalent to legal truth.

16. Epistemic Limits and Expert Dependence

There is a potential danger of expert epistemic substitution.

This occurs when:

Court → expert report → judgment

replaces the more appropriate structure:

Court → evidence → expert analysis → party objections → judicial evaluation → judgment.

The UAE framework contains mechanisms designed to prevent expert evidence from becoming completely uncontestable. Dubai's expert-witness legislation requires experts to work within their assigned mandate and provides for consideration of party objections and, where necessary, reconsideration or another expert.

17. Epistemic Limits and Procedural Fairness

A party must have a meaningful opportunity to challenge the evidentiary foundation of the opposing party's case.

This includes, depending on the circumstances:

• access to relevant evidence;
• opportunity to respond to expert findings;
• opportunity to challenge calculations;
• opportunity to submit counter-evidence;
• opportunity to identify inconsistencies.

This is important because a court's factual knowledge is partly generated through the adversarial process.

18. Judicial Reasoning as an Epistemic Control Mechanism

Reasoned judgments serve at least three functions.

First — Explanation

They show the parties why they won or lost.

Second — Error detection

They permit an appellate court to determine whether the lower court:

• ignored evidence;
• misunderstood evidence;
• applied the wrong legal rule;
• relied on insufficient reasoning.

Third — Institutional legitimacy

A reasoned judgment demonstrates that the outcome emerged from a legal and evidentiary process rather than unexplained intuition.

This explains why UAE case law places importance on adequate reasoning concerning expert reports and material evidence.

19. Epistemic Closure in Civil Adjudication

A civil case must eventually reach an endpoint.

If the court demanded absolute certainty, litigation could theoretically continue indefinitely.

The legal system therefore creates epistemic closure.

The sequence is:

1. parties submit claims;
2. evidence is produced;
3. evidence is challenged;
4. experts may be appointed;
5. factual issues are determined;
6. law is applied;
7. judgment is issued;
8. appellate mechanisms operate;
9. the judgment eventually becomes final.

Thus:

Epistemic closure ≠ absolute truth.

It means that the legal system reaches a sufficiently justified and procedurally final determination.

20. Epistemic Limits and Finality

This distinction is particularly important in civil law.

A judgment can become legally final even though:

• some factual uncertainty remains;
• experts disagree;
• evidence was incomplete;
• the precise historical truth cannot be reconstructed.

The purpose of civil adjudication is therefore not necessarily to achieve metaphysical certainty.

Its function is to produce an authoritative legal determination based on the evidence and law available within the proceedings.

21. Relationship Between Evidence, Expertise and Judicial Discretion

22. Important Legal Principle

The central principle can be expressed as:

A UAE civil court decides according to legally established evidence, not according to an obligation to discover absolute factual truth.

This does not reduce the court's authority. Instead, it defines the legitimate boundaries within which that authority operates.

23. Six Core Epistemic Safeguards

The UAE civil adjudicatory system can therefore be understood as using six principal safeguards:

1. Burden of proof

Allocates responsibility for establishing disputed facts.

2. Evidentiary rules

Control how facts can be demonstrated.

3. Expert evidence

Bridges technical knowledge gaps.

4. Adversarial challenge

Allows parties to test the reliability of evidence.

5. Reasoned judgment

Requires the court to connect evidence with conclusions.

6. Appellate review

Provides institutional correction of legal and reasoning errors.

24. Overall Conclusion

Epistemic limits of UAE civil adjudication describe the unavoidable gap between objective reality and what can be legally demonstrated in litigation.

The court may never possess perfect knowledge of a historical event, technical failure, financial loss, environmental injury, algorithmic decision, or contractual counterfactual. UAE civil procedure and evidence law therefore provide mechanisms for managing uncertainty rather than pretending that uncertainty does not exist.

The case law concerning expert reports, material evidence, admissions, factual evaluation, competing technical opinions and proof of damages demonstrates several recurring principles:

• an expert is not the judge;
• technical evidence must remain open to challenge;
• material objections should be considered;
• liability and damages require separate evidentiary foundations;
• factual evaluation primarily belongs to the trial court;
• judgments must provide sufficient reasoning;
• appellate review does not necessarily involve a complete retrial of every factual question.

The most useful conceptual formula is:

Reality → Evidence → Proof → Judicial Evaluation → Legal Characterization → Judgment → Finality

The epistemic limit exists between reality and proof; the legal system's task is to manage that gap through evidence, expertise, reasoning and procedural finality.

Important qualification: “epistemic limits of civil adjudication” is a theoretical/conceptual category rather than a named UAE cause of action. Accordingly, the cases above are foundational authorities illustrating evidence, expert reliance, factual evaluation, reasoning and proof rather than cases formally titled “epistemic limits.”
