Civil Law and UAE — Ultra-Deep Limits of Norm Creation in Post-Codified Systems

1. Introduction

“Limits of norm creation in post-codified systems” is a theoretical way of asking:

After a legal system has already been extensively codified, how far can judges, courts, regulators, parties, custom, and legal scholarship go in creating new legal norms?

This question is particularly interesting in the UAE because the UAE is not simply a single legal methodology.

There is:

• federal codified civil law;
• Emirate-level legislation;
• specialised free-zone legislation;
• DIFC common-law methodology;
• ADGM common-law methodology;
• Sharia-derived principles incorporated through legislation;
• custom where legislation permits it;
• judicial interpretation;
• international conventions and treaties.

The current federal starting point is especially important. Federal Decree-Law No. 25 of 2025 promulgating the Civil Transactions Law became effective on 1 June 2026. Article 1 creates a hierarchy for filling gaps: legislation first; then Islamic Sharia where legislation provides no answer; then custom; and finally principles of natural law and rules of justice. It also states that there is no room for ijtihad where the legislative text is definitive. Article 2 directs courts to the principles of Islamic jurisprudence for understanding, interpretation and construction of legislative texts.

Therefore, the central proposition is:

A post-codified UAE legal system permits judicial development, but not unlimited judicial legislation.

2. What Is a “Post-Codified System”?

A codified legal system attempts to place fundamental legal rules into organised legislative texts.

A post-codified system is one in which codification already exists, but new problems continually arise.

Examples include:

• artificial intelligence;
• digital assets;
• blockchain;
• new financial products;
• new corporate structures;
• cross-border transactions;
• new forms of evidence;
• technological torts;
• novel contractual arrangements.

The problem becomes:

When the code does not expressly answer the new problem, who creates the next legal rule?

Possible candidates include:

1. Legislature
2. Courts
3. Regulators
4. Custom
5. Contracting parties
6. Sharia principles
7. Legal scholarship
8. International legal instruments

But each has different normative authority.

3. The Central Distinction

The most important distinction is:

Interpretation is not automatically legislation.

A judge may:

• interpret ambiguous language;
• apply an existing principle;
• fill a legally authorised gap;
• develop an existing doctrine incrementally.

But a judge cannot necessarily:

invent an entirely new rule merely because the judge considers it desirable.

This boundary has been made particularly clear in DIFC jurisprudence.

4. Current UAE Civil Transactions Law — The Norm-Creation Ladder

Article 1 of the current Civil Transactions Law creates a remarkably important hierarchy.

First level — Legislation

Apply legislative provisions to matters they expressly or implicitly address.

Second level — Sharia

If applicable legislation contains no answer:

Apply Islamic Sharia and select the appropriate solution according to Maslaha.

Third level — Custom

If Sharia contains no applicable ruling:

Apply custom, provided it does not conflict with public order or public morals.

Fourth level — Natural law and justice

If custom contains no solution:

Apply principles of natural law and rules of justice.

Ultra-basic formula

LAW → SHARIA → CUSTOM → NATURAL LAW/JUSTICE

This is not simply an academic hierarchy. It defines the institutional boundary of judicial norm creation.

5. Definitive Text — The Hardest Boundary

Article 1 of the 2025 Civil Transactions Law expressly says:

No room for independent legal reasoning where the legislative text is definitive in its indication.

This produces one of the strongest limitations on judicial creativity.

Therefore:

If Parliament/legislator has clearly enacted:

Rule X

the court cannot ordinarily replace it with:

Judge's preferred Rule Y.

Formula

Definitive Text → Application, Not Judicial Replacement

6. But “Clear” Does Not Mean “No Interpretation Ever”

A difficult question is:

Who decides whether a provision is actually clear?

The court must often determine:

• meaning;
• scope;
• context;
• interaction with other provisions;
• exceptions;
• temporal application;
• territorial application.

Therefore, the boundary between interpretation and legislation can be difficult.

Two extremes

Extreme 1

“Judges can never develop law.”

Too narrow.

Extreme 2

“Judges can create whatever rule they think appropriate.”

Too broad.

The more accurate approach is:

Courts interpret and incrementally develop law within the authority granted by the legal system.

7. Norm Creation vs Norm Recognition

A court may appear to “create” a rule when it is actually:

• recognising a principle already contained in legislation;
• resolving ambiguity;
• applying an existing general principle to new facts;
• identifying the consequences of an existing rule.

Example

The statute says:

“A party must act in good faith.”

A court deciding what conduct constitutes bad faith is developing the application of the norm.

That is different from announcing:

“From today, every commercial contract has a new obligation that Parliament never enacted.”

Memory rule

Application ≠ Creation

8. The Problem of Judicial Legislation

Judicial legislation occurs when a court goes beyond legitimate interpretation and effectively introduces a new legal rule that should properly come from the legislature.

This distinction is particularly important in the DIFC.

The leading authority is:

The Industrial Group Limited v Abdelazim El Shikh El Fadil Hamid

[2022] DIFC CA 005 & 006

The DIFC Court of Appeal expressly stated that although DIFC law is interpreted and developed incrementally through common-law methodology, the courts must remain within the statutory framework.

The court held that judicially incorporating entirely new torts into DIFC law would amount to impermissible judicial legislation.

Core principle

Common-law methodology does not give DIFC courts unlimited law-making power.

Memory

Industrial Group = No judicial legislation

9. Why Industrial Group Is Extremely Important

This case provides a theoretical answer to the user's question.

The DIFC Court of Appeal recognised two propositions simultaneously:

Proposition 1

DIFC law can be:

interpreted and developed incrementally

Proposition 2

The court must not:

cross the line into impermissible judicial legislation

This is the essential boundary of norm creation in a post-codified system.

10. Pearl Petroleum — Statutory Framework Controls

Pearl Petroleum Company Ltd & Others v Kurdistan Regional Government of Iraq

[2017] DIFC ARB 003

The DIFC Court explained that its jurisdiction is founded on statutory provisions.

It rejected the idea that the court could simply import an external body of law when the statutory framework did not provide for doing so.

The court stated that DIFC law proceeds through common-law methodology and incremental development, but courts have no power to create law by importing an external body of law without statutory authority.

Principle

Common-law reasoning is a methodology, not a licence for unlimited borrowing.

Memory

Pearl Petroleum = No free importation of external law

11. Fal Oil — Incremental Development Has a Boundary

Fal Oil Company v Sharjah Electricity and Water Authority

[2019] DIFC ENF 221

The DIFC Court reiterated that DIFC law is interpreted using common-law methodology and develops incrementally.

But the court also emphasised:

The courts cannot create law merely by importing an external body of law where the statutory framework does not permit it.

Principle

Incremental development must have a statutory/legal foundation.

Memory

Fal Oil = Incremental ≠ unlimited

12. Dubai International Financial Centre Authority — Judicial Power Has Defined Scope

Dubai International Financial Centre Authority [2020] DIFC CA 002

The Court of Appeal explained that the court's authority is defined by the applicable statutory framework.

Its jurisdiction to interpret DIFC laws and regulations is itself legally conferred.

Principle

A court's power to interpret law is itself a legal power created by law.

This creates a recursive boundary:

The judge interprets law because the legal system gives the judge that authority.

Memory

DIFCA = Interpretation power comes from law

13. Lural v Listran — Jurisdiction Cannot Be Created by Judicial Preference

Lural v Listran & Lokhan

[2021] DIFC CA 003

The DIFC Court of Appeal emphasised that DIFC jurisdiction is determined by the Judicial Authority Law and that the UAE Civil Procedure Law does not govern DIFC jurisdiction.

The case illustrates an important boundary:

Courts cannot manufacture jurisdiction merely because a dispute appears appropriate for them.

Formula

Jurisdiction = Statutory Gateway + Applicable Legal Rules

Memory

Lural = No self-created jurisdiction

14. Ashok Kumar Goel v Credit Suisse — Interpretation Has Methodological Limits

Ashok Kumar Goel & Others v Credit Suisse

[2021] DIFC CA 002

The case concerned interpretation of jurisdiction clauses and the meaning of contractual language.

The Court of Appeal applied the UAE Civil Code's contractual interpretation framework, including the distinction between:

• clear wording; and
• circumstances requiring interpretation of mutual intention.

The court endorsed an objective approach based on the words used, background circumstances, transaction and context.

Principle

Interpretation develops meaning from the legal text and context; it does not amount to inventing an unrelated bargain.

Memory

Goel = Contextual interpretation, not contractual invention

15. Nihan v Nicholas & Niaz — Multiple Legal Systems Create Multiple Normative Contexts

Nihan v Nicholas & Niaz

[2024] DIFC CA 012

This case is important because it demonstrates that even the concept of public policy can have different legal functions.

The DIFC Court distinguished:

• public policy under domestic UAE Civil Code provisions; and
• public policy as a ground for refusing recognition or enforcement of an arbitral award under international arbitration instruments.

The Court recognised that these are not automatically identical concepts.

Norm-creation significance

A post-codified system may contain multiple normative layers.

Therefore:

One legal phrase does not necessarily create one universal rule in every legal context.

Memory

Nihan = Context controls normative meaning

16. Egan & Eggert v Eava & Efa — Statute Is a Primary Normative Source

Egan & Eggert v Eava & Efa

[2013] DIFC ARB 002

The court discussed UAE public policy and recognised the significance of enacted legislation as a primary source of public policy.

The case is useful for demonstrating that judicial reasoning about public policy begins with the legally enacted framework rather than an abstract judicial preference.

Principle

Courts identify public-policy norms primarily from recognised legal sources.

Memory

Egan = Enacted law → Public-policy source

17. The Eight Cases — Master Table

These cases are predominantly DIFC authorities, so they should not be treated as binding precedents of UAE onshore courts. Their importance here is primarily comparative and structural, especially because the DIFC expressly operates through common-law methodology within a statutory framework.

18. UAE Onshore Norm Creation

For the UAE mainland civil-law system, the current Civil Transactions Law establishes a more explicit hierarchy.

Step 1

Legislation

Step 2

Sharia

Step 3

Custom

Step 4

Natural law and justice

This is different from the pure common-law idea of judges developing doctrine through binding precedent.

Therefore:

UAE mainland judicial reasoning is not equivalent to English common-law judicial law-making.

19. Role of Sharia

The current Article 1 expressly provides a role for Islamic Sharia when applicable legislation does not resolve the matter.

Article 2 also directs courts to use principles of Islamic jurisprudence for understanding, interpretation and construction of legislative texts.

This creates a distinctive normative structure:

Codification + Sharia principles + Custom + Justice

rather than:

Statute + unlimited judicial precedent

20. Role of Custom

Custom is a recognised gap-filling source under Article 1.

But custom is not unlimited.

It must not conflict with:

• public order;
• public morals.

If the custom is specific to an Emirate, the provision also recognises the possibility of its application within that Emirate.

Formula

Custom + Legal Recognition + Compatibility = Valid Gap-Filling Source

21. Can Courts Create Law From Custom?

Only within the statutory framework.

A court does not simply say:

“People usually do this, therefore it is law.”

It must establish:

1. legislative gap;
2. relevant custom;
3. sufficient legal relevance;
4. compatibility with public order/public morals.

Therefore:

Custom is a recognised source, but judicial recognition of custom is not unlimited judicial legislation.

22. Natural Law and Justice — The Final Gap-Filling Layer

The current Article 1 places principles of natural law and rules of justice at the end of the gap-filling sequence.

This is significant.

It means a court is not simply free to jump immediately to abstract fairness.

The structure requires the court to move through the legally established hierarchy.

Wrong approach

“The statute is inconvenient, so I will apply fairness.”

Structured approach

Legislation → Sharia → Custom → Natural law/justice

23. “Maslaha” and Judicial Creativity

Article 1 refers to selecting the most appropriate Sharia solution according to Maslaha where the statutory framework directs the court to Sharia.

This does not mean:

“The judge may do whatever produces the judge's preferred social result.”

Rather, the concept operates within the legally prescribed source hierarchy.

Memory

Maslaha operates inside the legal methodology; it does not abolish the methodology.

24. Definitive Text vs Open-Textured Text

This is one of the most important theoretical distinctions.

Definitive rule

Example:

“The period is 30 days.”

If the text is genuinely definitive, judicial substitution is highly constrained.

Open-textured rule

Example:

“reasonable,” “good faith,” “appropriate,” “fair,” “reasonable care.”

These terms necessarily require application to facts.

Therefore

The more open-textured the statute, the greater the interpretive space.

But:

Interpretive space ≠ unlimited norm creation.

25. The “Interpretive Space” Model

Think of judicial discretion as a spectrum:

0%

Definitive statutory command

↓

Strict application

↓

Contextual interpretation

↓

Principle-based interpretation

↓

Gap-filling expressly authorised by law

↓

Incremental doctrinal development

↓

Boundary

↓

Impermissible judicial legislation

The exact boundary depends on the legal regime.

26. Post-Codification Does Not Mean “Code Is Complete”

No civil code can predict every future problem.

New questions arise from:

• AI;
• cryptocurrency;
• smart contracts;
• autonomous systems;
• digital identity;
• metaverse assets;
• genetic technology;
• new financial instruments.

Therefore:

Codification reduces uncertainty; it does not eliminate legal evolution.

27. But Technological Novelty Does Not Automatically Create Judicial Power

Suppose an AI system causes a new kind of harm.

The judge cannot simply say:

“AI is new, therefore I create an entirely new tort.”

The proper sequence is:

1. Existing legislation?
2. Existing tort/contract/property principles?
3. Statutory analogy permitted?
4. Recognised general principles?
5. Authorised gap-filling?
6. Existing jurisprudence?
7. Legislative reform required?

This is particularly consistent with the reasoning in Industrial Group, where the DIFC Court refused to judicially create new torts merely because a perceived legal gap existed.

28. The Legislature's Special Position

The legislature has a distinctive democratic and constitutional function.

It can:

• create new rights;
• impose new duties;
• create new offences;
• establish new regulators;
• change limitation periods;
• redesign remedies;
• regulate emerging technology.

Judges generally:

• interpret;
• apply;
• develop within authorised boundaries.

Formula

Legislature = Primary norm-maker

Court = Interpreter/application + authorised incremental development

29. Regulators as Secondary Norm-Makers

Modern post-codified systems contain regulations and regulatory standards.

Examples include:

• financial regulation;
• data protection;
• digital assets;
• company regulation;
• professional licensing;
• real-estate regulation.

A regulator may create detailed rules only where legislation delegates that authority.

Therefore:

Delegated regulation is legally derived norm creation.

It is not equivalent to independent law-making power.

30. Contractual Norm Creation

Private parties also create micro-norms through contracts.

For example:

“Payment must be made on the 10th day.”

This creates a rule between A and B.

But it remains subordinate to:

• mandatory legislation;
• public order;
• public policy;
• applicable regulatory rules.

Formula

Contractual Norm → Private Effect → Legal Recognition → Mandatory-Law Boundary

31. Why Contract Cannot Create General Law

If A and B agree:

“All UAE companies must follow our interpretation.”

that agreement does not create a general legal norm.

It only creates contractual consequences between the parties if legally valid.

Important distinction

Contract creates private obligations.

Legislation creates generally applicable legal rules.

32. Judicial Precedent in the UAE

Another major boundary concerns precedent.

The UAE mainland system should not simply be described as a strict doctrine of stare decisis equivalent to England.

Judicial decisions are highly important for:

• interpretation;
• consistency;
• legal reasoning;
• application of statutes.

But the institutional structure differs from a pure common-law precedent system.

The DIFC is different: its courts use common-law methodology and develop DIFC law incrementally, while still operating within legislation.

Thus:

UAE onshore jurisprudence ≠ DIFC precedent system

33. The Post-Codified Paradox

The more detailed the code becomes, the more difficult the judicial task can sometimes become.

Why?

Because detailed legislation creates:

More text to interpret

but also:

Less legitimate space to contradict the text.

Paradox

More codification → more certainty + more interpretive complexity

34. The “Silence” Problem

Suppose legislation is silent.

Silence can mean different things:

Type 1 — Genuine legislative gap

The legislature simply did not anticipate the problem.

Type 2 — Deliberate omission

The legislature may intentionally have chosen not to regulate the issue.

Type 3 — Existing general rule applies

The answer is already implicit in broader legislation.

Type 4 — Another legal source supplies the answer

For example:

• Sharia;
• custom;
• natural law/justice.

The judge must therefore determine:

Is silence a gap or a boundary?

This is one of the hardest questions in post-codified legal reasoning.

35. The “Gap-Filling” Test

Before creating or extending a legal norm, ask:

Question 1

Is there an applicable statutory provision?

Question 2

Is its meaning definitive?

Question 3

If not, can it be interpreted?

Question 4

Does another statutory provision solve the problem?

Question 5

Does the statutory hierarchy identify another source?

Question 6

Would the proposed judicial rule contradict legislation?

Question 7

Would it effectively create a new right or liability?

Question 8

Is the matter better left to legislative reform?

36. Norm-Creation Risk Matrix

This is a conceptual study model, not a UAE statutory test.

37. Public Policy as a Boundary

Public policy prevents private and sometimes judicial legal development from becoming unlimited.

Nihan is particularly useful because the DIFC Court distinguished domestic UAE public policy from public-policy review under international arbitration instruments.

Therefore:

“Public policy” must always be analysed within its legal context.

38. The Deepest Limit: Constitutional Allocation of Power

At the highest level, legal norm creation is constrained by:

• UAE Constitution;
• federal legislative competence;
• Emirate legislative competence;
• specialised free-zone legislation;
• judicial authority laws;
• delegated regulatory powers.

Therefore:

A court cannot enlarge its own law-making jurisdiction simply by interpreting a statute broadly.

This is reflected structurally in Lural, DIFCA, and Industrial Group.

39. A Five-Layer Model of UAE Norm Creation

Layer 1 — Constitutional norm

Constitution

↓

Layer 2 — Legislative norm

Federal/Emirate/DIFC/ADGM legislation

↓

Layer 3 — Delegated norm

Regulations/rules

↓

Layer 4 — Judicial norm-development

Interpretation/application/authorised incremental development

↓

Layer 5 — Private ordering

Contracts/customary practices

Each lower layer must operate within the authority of the higher legal framework.

40. Ultra-Deep Boundary Formula

NORM VALIDITY = SOURCE + AUTHORITY + JURISDICTION + COMPETENCE + PROCEDURE + CONSISTENCY

A proposed legal norm becomes problematic where one of these disappears.

Example

A judge creates a new general tort.

Ask:

Source?
Where does the power come from?

Authority?
Does the court have law-making authority?

Jurisdiction?
Is this court legally empowered to decide the issue?

Competence?
Is the subject within judicial rather than legislative competence?

Procedure?
Was the rule created through the legally recognised process?

Consistency?
Does it conflict with legislation?

If these questions cannot be answered satisfactorily, judicial norm creation becomes problematic.

41. The “Three Boundaries” Model

The entire subject can be reduced to three boundaries.

Boundary A — Text

What does the enacted law permit?

Boundary B — Method

What interpretive/gap-filling methods does the legal system permit?

Boundary C — Institution

Which institution has authority to create the rule?

Formula

TEXT + METHOD + INSTITUTION = LEGITIMATE NORM DEVELOPMENT

42. Onshore UAE vs DIFC

The DIFC cases make the final two distinctions particularly clear.

43. AI and Post-Codified Norm Creation

AI creates an especially difficult boundary question.

Suppose no statute specifically regulates a new AI-generated contractual harm.

The court should not automatically create:

“AI Tort No. 1.”

Instead, it should ask whether existing principles of:

• contract;
• negligence/harmful acts;
• agency;
• product liability;
• professional responsibility;
• evidence;
• data protection

already provide an answer.

AI formula

New Technology ≠ New Judicial Power

44. Smart Contracts

A smart contract may execute automatically.

But automatic execution does not eliminate:

• contractual interpretation;
• validity;
• capacity;
• mistake;
• fraud;
• illegality;
• public policy;
• remedies.

Thus:

Code execution is not necessarily legal finality.

The legal system determines whether the underlying arrangement is legally recognised.

45. Digital Assets

Digital assets create new objects of economic value.

But the legal system still asks:

Who owns it?

What legal interest exists?

How was it transferred?

Was the transaction valid?

Which law applies?

Which court has jurisdiction?

What remedy is available?

Therefore:

Technology expands factual possibilities faster than it expands legitimate judicial norm-creation authority.

46. Why “Post-Codified” Does Not Mean “Post-Law”

A common theoretical mistake is:

“The code is incomplete, therefore judges are free to make law.”

That is incorrect.

The proper principle is:

An incomplete code creates a need for legally authorised interpretation and gap-filling, not unlimited judicial sovereignty.

47. Ultra-Deep Examination Answer

If asked:

“What are the limits of norm creation in a post-codified UAE legal system?”

A strong answer is:

The limits arise from the hierarchy of legal sources, the distinction between interpretation and legislation, institutional competence, definitive statutory text, public order, public morals, jurisdiction and the constitutionally allocated powers of legislative and judicial institutions. Under Article 1 of the current UAE Civil Transactions Law, legislation is the primary source; where legislation is silent, the statutory framework directs the court successively to Islamic Sharia, custom and, finally, principles of natural law and rules of justice. The same provision restricts independent legal reasoning where legislative text is definitive. In the DIFC, courts use common-law methodology and develop law incrementally, but cases such as Industrial Group establish that this does not permit impermissible judicial legislation. Accordingly, post-codification permits legal development, but that development must remain source-based, institutionally authorised, methodologically disciplined and consistent with higher legal norms.

48. Ultra-Rapid Revision Table

49. Master Case-Law Memory

I-P-F-D-L-G-N-E

I — Industrial Group → No judicial legislation
P — Pearl Petroleum → No unsupported external-law importation
F — Fal Oil → Incremental development
D — DIFCA → Statutory interpretation authority
L — Lural → Jurisdictional boundary
G — Goel → Methodological interpretation
N — Nihan → Contextual public policy
E — Egan & Eggert → Enacted law as normative source

50. Final Conceptual Conclusion

The deepest lesson is that codification does not freeze private law, but neither does legal incompleteness give courts unlimited authority to legislate.

The UAE's current Civil Transactions Law expressly structures what happens when legislation is silent: legislation → Sharia → custom → natural law and justice, while definitive legislative text constrains independent legal reasoning.

The DIFC provides the complementary common-law example: its courts can interpret and develop law incrementally, but Industrial Group, Pearl Petroleum and Fal Oil demonstrate that the development must remain anchored to the statutory framework and cannot become impermissible judicial legislation.

Ultimate formula

CODIFICATION → INTERPRETATION → AUTHORISED GAP-FILLING → INCREMENTAL DEVELOPMENT → BOUNDARY → LEGISLATION

And the deepest rule to remember is:

A post-codified legal system permits evolution of norms, but the authority to evolve a norm must itself come from the legal system.
