Civil Law and UAE: Semantic Drift in Statutory Interpretation Over Time

1. Introduction

Semantic drift means that the practical meaning or legal effect of a statutory word, phrase, or concept may change over time because of changes in society, technology, commercial practice, related legislation, judicial interpretation, or the replacement of an older statute with a newer one.

In UAE civil law, semantic drift is particularly important because the UAE has a codified civil-law system. Courts generally begin with statutory text, but interpretation also considers context, purpose, jurisprudential principles, custom, and the relationship between general and special legislation.

There is now an especially important historical break. Federal Decree-Law No. 25 of 2025 promulgating the Civil Transactions Law entered into force on 1 June 2026 and repealed Federal Law No. 5 of 1985. Therefore, an expression interpreted by courts under the 1985 Civil Code cannot automatically be assumed to have exactly the same legal meaning under the 2025 Civil Transactions Law. (UAE Legislation)

The subject can therefore be expressed as:

Same words → changed social/legal context → changed interpretive environment → potentially changed practical meaning.

2. Meaning of Semantic Drift

Semantic drift in statutory interpretation occurs when a statutory expression retains substantially the same wording but its legal application changes over time.

For example, words such as:

“property”

“writing”

“document”

“communication”

“damage”

“reasonable”

“custom”

“public interest”

“law”

“judicial decision”

“permitted by law”

may acquire new practical significance as technology, business models and legislation develop.

Important distinction

Semantic drift is not the same as judicial amendment of legislation.

A court should not simply rewrite a statute because society has changed. Instead, the court interprets the existing statutory language within its permissible meaning.

The distinction is:

3. Current UAE Legislative Framework

The starting point in 2026 is the new Civil Transactions Law under Federal Decree-Law No. 25 of 2025.

The new legislation entered into force on 1 June 2026 and expressly repealed the 1985 Civil Transactions Law. (UAE Legislation)

The UAE Government describes the new law as part of a broader modernization of the civil-law framework, including clearer legal concepts, integration with special legislation, contemporary transactions and greater judicial flexibility where legislation does not directly resolve an issue. (UAE Legislation)

Article 2 of the new Civil Transactions Law

The new law expressly directs that the principles and rules of Islamic jurisprudence (Usul al-Fiqh) are to be considered in understanding, interpreting and construing legislative texts. (LEXAI)

This is important for semantic drift because interpretation is not necessarily frozen at the moment a provision was originally drafted.

4. The Central Problem: Old Meaning vs Current Meaning

A UAE court dealing with a modern dispute may face three different questions:

Question 1 — What did the provision mean when enacted?

This is the historical meaning.

Question 2 — How did UAE courts subsequently interpret it?

This is the judicial-development dimension.

Question 3 — Does the same expression under the new 2025 Civil Transactions Law have the same meaning?

This requires comparison of:

wording;

structure;

legislative purpose;

surrounding provisions;

special legislation;

transitional provisions;

judicial authorities.

Therefore:

A 1985 case remains useful evidence of UAE legal reasoning, but it is not automatically a statement of current 2026 statutory law.

This distinction is extremely important in examination and legal research.

5. Main Sources of Semantic Drift in UAE Civil Law

A. Technological change

Older statutes were drafted when:

paper documents were dominant;

physical possession was central;

contracts were signed manually;

banking was largely physical;

communication was predominantly face-to-face.

Modern disputes involve:

electronic signatures;

cloud records;

AI;

blockchain;

digital assets;

automated contracting;

electronic communications.

The words of an old statute may therefore have to be applied to facts that the original legislature could not have specifically contemplated.

B. Commercial change

Commercial practice changes the factual environment in which legal concepts operate.

For example:

“custom” in a commercial transaction may have a different practical content in 2026 from the commercial custom existing several decades earlier.

This does not mean custom overrides mandatory law. Rather, where legislation permits reliance upon custom, the relevant contemporary custom may become important.

C. Legislative interaction

Meaning can change because another statute is enacted.

A general civil-law provision may acquire a narrower practical application after a special statute regulates the same subject.

The UAE's modern legislative framework increasingly operates through interaction between:

Civil Transactions Law;

Companies legislation;

data-protection legislation;

electronic-transactions legislation;

consumer law;

arbitration legislation;

insolvency law;

sector-specific legislation.

The UAE Government itself describes the 2025 Civil Transactions Law as seeking to eliminate duplication and harmonise the general civil framework with newer special legislation. (UAE Legislation)

D. Judicial interpretation

Courts may repeatedly interpret the same expression in different factual environments.

Over time, this produces an interpretive trajectory:

Text → early interpretation → later cases → new factual context → refined meaning.

6. Case Law

Case 1 — Dubai Court of Cassation, Judgment No. 9 of 2021

This is an important example of the distinction between literal meaning and contextual interpretation.

The Dubai Court of Cassation considered an arbitration clause providing for arbitration while also referring to the jurisdiction of Dubai Courts.

The Court explained that under the former Article 265 of the Civil Code:

clear contractual wording should not be displaced by interpretation;

where interpretation is necessary, the common intention of the parties can be examined;

the nature of the transaction and commercial trust/custom may be relevant.

The Court also emphasised that arbitration clauses are exceptional because court jurisdiction is the general rule, so an arbitration agreement should not be extended beyond its proper meaning. (Dubai Culture)

Importance for semantic drift

The case demonstrates that the meaning of words depends partly upon their legal and transactional context.

A phrase such as “without prejudice to the jurisdiction of Dubai Courts” cannot be understood merely by looking at one isolated sentence.

Principle

Words must be interpreted within the complete legal and contractual context, but clear language cannot simply be replaced by judicial preference.

7. Case 2 — Credit Suisse (Switzerland) Ltd v Goel [2020] DIFC CFI 066

This DIFC Court decision considered UAE Civil Code Article 265.

The Court explained that where the wording is unclear, interpretation seeks the mutual intention of the parties, rather than merely applying the literal meaning of individual words. It also discussed the Ministry of Justice commentary on the Civil Code. (DIFC Courts)

Although this was a DIFC decision, it is useful because it demonstrates how UAE civil-law interpretive methodology was understood in the context of UAE law.

Importance

The case shows that statutory or contractual meaning is not necessarily determined by dictionary meaning alone.

A word can acquire legal significance through:

context;

transaction;

established practice;

surrounding provisions.

Semantic-drift lesson

A commercial expression that once had a relatively simple meaning may acquire a more sophisticated legal meaning after decades of judicial interpretation.

8. Case 3 — NMC Healthcare Ltd v Neopharma LLC [2024] ADGMCFI 0013

This is one of the most directly relevant authorities for statutory semantic drift.

The ADGM Court considered principles for interpreting UAE federal legislation.

The Court referred to the former Article 1 of the Civil Code, under which legislative provisions were applied in their letter and context/spirit, and accepted that the purpose or intention of legislation may be relevant. It also recognised that an interpretation producing an illogical result may be rejected where that result cannot reasonably have been intended by the legislature. (BAILII)

The judgment also discussed Article 262 and Article 30 of the former Civil Code, including the principle that exceptions should not be extended by analogy. (BAILII)

Importance

This demonstrates an important balance:

Textual certainty + contextual interpretation + legislative purpose + limits on judicial extension.

Semantic-drift principle

A statutory word may be understood in light of its current legal context, but courts cannot use “modern context” as a licence to create an entirely new rule.

9. Case 4 — NMC Healthcare Ltd v Shetty & Ors [2025] ADGMCFI 0029

This is particularly useful because it demonstrates how the same terminology may acquire meaning from earlier judicial interpretation.

The Court considered provisions of the 2018 and 2025 anti-money-laundering legislation and discussed the principle that where legislation adopts terminology already used in earlier legislation, and courts have previously interpreted that terminology, there is a presumption that the legislature intended the terminology to carry the previously established meaning. (BAILII)

The Court also considered the former Civil Code principle that an exception should not be expanded by analogy and discussed Article 262's rule concerning unrestricted wording. (BAILII)

Why this matters

This is almost the reverse of semantic drift.

Sometimes legislation preserves meaning rather than changes it.

Thus:

Repeated legislative terminology + established judicial interpretation = possible continuity of meaning.

But if the new legislature changes the wording or structure, the argument for continuity becomes weaker.

10. Case 5 — Thamer Abdulaziz Albulaihid v Nasser Shehata / Health Insights [2023] DIFC CFI 079

This case is especially significant for temporal interpretation.

The DIFC Court considered whether the 2021 UAE intellectual-property legislation should retrospectively change ownership consequences relating to works created before that legislation came into force.

The Court relied on constitutional principles concerning non-retrospectivity and concluded that, absent clear legislative language, legislation should not be construed as retrospectively changing legal consequences that had already arisen. (DIFC Courts)

Importance for semantic drift

Semantic change cannot simply be used to rewrite historical legal relationships.

There is a major distinction between:

applying an existing provision to new facts; and

retrospectively changing the legal consequences of completed events.

Principle

Evolution of legal meaning does not automatically justify retrospective alteration of accrued rights.

This is extremely important after the replacement of the 1985 Civil Transactions Law by the 2025 Law.

11. Case 6 — Federal Supreme Court, Case No. 305/2014

This case is discussed in later UAE-law litigation concerning the meaning of the expression “permitted by law”.

The case involved whether authentication requirements imposed through ministerial regulation formed part of the relevant legal framework.

The later NMC judgment recorded the Federal Supreme Court's use of “law” in a broader sense capable, depending on context, of encompassing delegated legislation. (BAILII)

Importance

This illustrates how a single word such as “law” can have different legal scope depending upon:

statutory context;

subject matter;

legislative structure;

the purpose of the provision.

Semantic-drift lesson

A term does not necessarily possess one mechanically fixed meaning across every UAE statute.

12. Case 7 — Abu Dhabi Court of Cassation, Case No. 295/2017

This decision concerned privacy and photography in an aviation context.

As discussed in the later NMC judgment, the Court considered conduct carried out pursuant to aviation safety procedures approved by the competent aviation authority and treated it as being “permitted by law.” (BAILII)

Importance

This demonstrates that legal meaning can depend heavily upon the regulatory environment surrounding an activity.

An expression such as:

“permitted by law”

may encompass more than a narrowly defined federal statutory provision, depending upon its context.

Semantic-drift lesson

As regulatory systems become more sophisticated, seemingly simple statutory expressions may acquire broader or more technically differentiated applications.

13. Case 8 — Frontline Development Partners Ltd v Asif Hakim Adil [2016] DIFC CA 006

This case is not a mainland Civil Transactions Law case, so it should be used as comparative UAE judicial reasoning rather than as a binding mainland precedent.

The DIFC Court considered competing approaches to statutory interpretation, including:

literal interpretation;

purposive interpretation;

the mischief rule;

the golden rule.

The Court considered the legislative purpose behind wage-protection provisions and refused to treat interpretation as unlimited judicial rewriting. (DIFC Courts)

Importance

The case illustrates a universal interpretive problem:

When literal wording and legislative purpose appear to pull in different directions, how far can a court go?

The answer is that purposive interpretation may assist construction, but there is a boundary between interpreting legislation and rewriting it.

14. Case 9 — Asif Hakim Adil v Frontline Development Partners [2014] DIFC CFI 015

The first-instance proceedings are also useful because the Court expressly distinguished interpretation from legislative rewriting.

The Court stated, in substance, that adding substantial new words to a statute may amount to rewriting rather than construction. (DIFC Courts)

Importance

This provides an important limit on semantic drift.

Even if society changes:

The court cannot simply invent statutory language that the legislature did not enact.

15. How Semantic Drift Happens in UAE Civil Law

The process can be illustrated as follows:

Stage 1 — Original statutory meaning

The legislature adopts a term in a particular historical environment.

↓

Stage 2 — Judicial interpretation

Courts decide disputes involving the term.

↓

Stage 3 — Repeated judicial usage

Later courts rely upon earlier interpretations.

↓

Stage 4 — Social and technological change

The factual meaning of the underlying activity changes.

↓

Stage 5 — New legislation

The legislature may preserve, modify, narrow or expand the terminology.

↓

Stage 6 — New judicial interpretation

Courts determine whether old authorities remain applicable.

16. Semantic Drift After the 2026 Civil Transactions Reform

This is particularly important today.

The 1985 Civil Transactions Law was repealed on 1 June 2026 and replaced by Federal Decree-Law No. 25 of 2025. (UAE Legislation)

Consequently, UAE legal research now has a temporal interpretation problem.

Old case

A judgment may say:

Article 246 means X.

Current legislation

The same subject may now be governed by a different article, different wording or different structure.

Correct approach

The lawyer should ask:

What law governed the transaction?

When did the relevant legal event occur?

Was the right already accrued before 1 June 2026?

What transitional provision applies?

Has the new law preserved the old wording?

Has the legislative structure changed?

Is the old case interpreting a principle that survives in substance?

Is the old case dependent upon an article that no longer exists?

17. Semantic Drift and Contract Interpretation

The 2025 Civil Transactions Law continues to recognise the distinction between:

clear contractual wording; and

circumstances requiring interpretation.

The current law contains provisions directing courts to seek the common intention of the contracting parties where interpretation is necessary, considering the nature of the transaction and honesty/trust in accordance with prevailing custom. (LEXAI)

Therefore, semantic evolution can also occur in contract law.

For example:

“Electronic communication”

could historically have been understood primarily as email.

Today, depending upon the relevant legislation and context, the factual universe may include:

messaging platforms;

electronic portals;

automated system communications;

API-generated notices;

digitally authenticated records.

The legal question is not simply:

“What does this word mean in a dictionary?”

It is:

“What legal meaning does the word have within the applicable statute, its context, purpose and surrounding legal framework?”

18. Semantic Drift and Technology

Technology is one of the largest sources of contemporary semantic pressure.

Consider the concept of “document.”

Historically:

Document → paper instrument.

Modern civil litigation:

Document → electronic record, database entry, digitally generated record, cloud-stored material, potentially AI-generated material.

But the court must distinguish between:

technological development;

statutory definition;

evidentiary rules;

authenticity;

reliability;

legal effect.

Thus, technological evolution does not automatically change the statutory meaning.

19. Semantic Drift and Custom

Custom is particularly important because custom itself changes.

Suppose a civil-law rule refers to:

“custom prevailing in transactions.”

The relevant custom may evolve as commercial practice changes.

For example:

Traditional banking

→ physical signature → paper instructions.

Modern banking

→ electronic authentication → digital instructions → automated verification.

Therefore, a reference to commercial custom may have a changing factual content without the statutory wording changing.

This is a classic example of dynamic semantic application.

20. Semantic Drift and the Principle of Legal Certainty

Semantic drift creates a tension between two values.

Value 1 — Legal certainty

Citizens and businesses should be able to predict what the law means.

Value 2 — Legal adaptability

Law must remain capable of dealing with new circumstances.

The solution is not unlimited judicial flexibility.

Instead:

Interpretation should evolve within the boundaries established by legislation.

The NMC cases are particularly useful here because they recognise contextual and purposive interpretation while also emphasising limits on expanding exceptions and statutory language. (BAILII)

21. Semantic Drift vs Judicial Activism

These concepts should not be confused.

The UAE cases discussed above generally demonstrate an effort to maintain this boundary.

22. Special Importance of Arabic Legal Text

UAE legislation is enacted authoritatively in Arabic.

The official UAE legislation platform expressly warns that where there is a conflict between translations, the Arabic text prevails. (UAE Legislation)

This creates another potential source of semantic variation.

A translated English term may appear to have:

one dictionary meaning;

while the Arabic expression may have:

a broader technical meaning;

a civil-law meaning;

a jurisprudential meaning;

a context-dependent meaning.

Therefore, sophisticated UAE statutory interpretation should not rely exclusively on an unofficial English translation where the exact legal meaning is disputed.

23. Role of Islamic Jurisprudence

The current Civil Transactions Law expressly provides for reference to principles of Islamic jurisprudence in understanding, interpreting and construing legislative texts. (LEXAI)

This is important because semantic meaning in UAE civil law cannot always be analysed exclusively through common-law-style textual methods.

The interpretive framework may involve:

Statutory text

↓

Context and structure

↓

Principles of Islamic jurisprudence

↓

Purpose and legal coherence

↓

Custom where legally relevant

↓

Application to facts

This gives UAE civil-law interpretation a distinctive methodological character.

24. Practical Test for Identifying Semantic Drift

For an examination or legal research problem, use the following S-D-I-F-T test:

S — Statutory wording

What exactly does the provision say?

D — Date

When was the provision enacted and when did the relevant event occur?

I — Interpretation

How have UAE courts previously interpreted the expression?

F — Framework

What other legislation, custom, jurisprudence or regulations affect the meaning?

T — Transition

Does the 2025 Civil Transactions Law or another new statute change the applicable rule?

25. Example

Assume a contract from 2019 contains a clause referring to a “written notice.”

A dispute arises in 2026.

The lawyer should not immediately assume:

“Written notice means email.”

Instead, examine:

the law applicable to the contract;

the wording of the contract;

applicable electronic-transactions legislation;

the parties' established practice;

judicial decisions concerning electronic communications;

whether the new Civil Transactions Law applies;

whether the new law changes the legal consequence;

whether the parties expressly agreed to a particular form of notice.

This is semantic interpretation rather than merely dictionary interpretation.

26. Six Major Principles from the Case Law

27. Difference Between 1985 and 2025 Civil Transactions Law

This distinction is essential for current UAE legal research.

The UAE Government characterises the new law as a comprehensive modernization of civil law intended to make legal rules clearer and more coherent. (UAE Legislation)

28. Legal Consequences of Semantic Drift

Semantic drift can affect:

1. Contract validity

Whether an expression creates a binding obligation.

2. Liability

Whether a person's conduct falls within a statutory duty.

3. Damages

Whether a particular loss is legally recoverable.

4. Property

Whether a new type of asset fits an existing legal category.

5. Evidence

Whether technologically generated material fits an existing evidentiary concept.

6. Regulatory compliance

Whether a modern business activity falls within older statutory terminology.

7. Limitation

Whether a claim falls within a particular statutory category.

8. Transitional disputes

Whether the old or new Civil Transactions Law governs.

29. Important Limitation

There is not yet a large body of reported mainland UAE case law interpreting the 2025 Civil Transactions Law, because the new law only became effective on 1 June 2026.

Accordingly, most of the established cases discussed above were decided under the former 1985 Civil Transactions Law or involve UAE federal legislation in other contexts.

They should therefore be classified as:

historical interpretive authorities, persuasive methodological authorities, or authorities concerning continuing principles—not automatically as direct interpretations of every provision of the 2025 Civil Transactions Law.

This is especially important in a 2026 legal opinion.

30. Exam-Friendly Definition

Semantic drift in UAE statutory interpretation means the gradual change in the practical legal meaning or application of statutory expressions as courts encounter new factual, technological, commercial and regulatory circumstances. UAE courts generally preserve statutory certainty by respecting clear language while using context, legislative purpose, jurisprudential principles and surrounding legislation where interpretation is genuinely required. The replacement of the 1985 Civil Transactions Law by Federal Decree-Law No. 25 of 2025 from 1 June 2026 creates an important new temporal dimension because earlier judicial interpretations must now be tested against the wording, structure and transitional rules of the new Civil Transactions Law. (UAE Legislation)

31. Conclusion

Semantic drift is an important feature of the evolution of UAE civil law, but it does not mean that courts are free to change statutory language whenever society changes.

The UAE approach seeks to balance:

Text + context + purpose + jurisprudential principles + custom + legal certainty.

The case law demonstrates several recurring propositions:

clear statutory or contractual language should normally be respected;

context becomes important where genuine ambiguity exists;

legislative purpose can assist interpretation;

established meanings may carry forward when terminology is repeated;

exceptions should not casually be expanded;

interpretation should not become judicial rewriting;

legal developments should not ordinarily operate retrospectively without clear authority; and

the 2025 Civil Transactions Law creates a new interpretive era from 1 June 2026.

The central principle can therefore be remembered as:

“Meaning may evolve with context, but judicial interpretation must remain anchored to the enacted legal framework.” (BAILII)
