Language Access Discrimination in Competition Law

1. Introduction

Language access discrimination occurs when an enterprise, platform, infrastructure operator, professional body, employer, or other market participant gives competitors, customers, suppliers, distributors, or users unequal access because of the language they use or because services, interfaces, documentation, contracts, APIs, support, or essential information are available only in a preferred language.

In competition law, language differences are not automatically unlawful. The central question is whether a language restriction is:

1. objectively justified;
2. genuinely necessary for the service or product;
3. proportionate to the legitimate objective;
4. applied consistently and transparently; and
5. capable of excluding competitors or disadvantaging particular groups in a relevant market.

The issue becomes particularly important where the undertaking controls an essential facility, digital platform, marketplace, payment system, API, telecommunications network, certification system, or other gateway to customers.

2. Meaning of Language Access Discrimination

Language access discrimination may take several forms:

A. Customer-access discrimination

A dominant platform may provide its principal interface, customer support, terms, or complaint mechanisms only in one language, while providing substantially better access to selected users.

B. Supplier or distributor discrimination

A platform may accept suppliers using one language but impose additional documentation, translation, verification, or certification requirements on suppliers using another language.

C. API and interoperability discrimination

A dominant digital infrastructure provider may provide API documentation, technical specifications, developer support, or testing tools only in a preferred language, making interoperability more difficult for competing developers.

D. Essential-facility access

Where an infrastructure operator controls an indispensable facility, refusing meaningful access because an applicant cannot communicate in a particular language can potentially constitute discriminatory access.

E. Contractual discrimination

Different language versions of contracts may contain materially different terms, particularly concerning:

• pricing;
• liability;
• termination;
• access conditions;
• dispute resolution;
• technical standards; or
• exclusivity.

F. Information asymmetry

A dominant undertaking may publish commercially important information in one language but delay or omit equivalent information in another language.

3. Competition-Law Framework

Language discrimination can potentially fall under several competition-law theories.

A. Abuse of dominant position

The strongest competition-law connection is usually discriminatory treatment by a dominant undertaking.

A competition authority would normally examine:

• relevant product market;
• geographic market;
• dominance;
• nature of the discriminatory treatment;
• similarly situated users or competitors;
• foreclosure effects;
• objective justification; and
• proportionality.

In jurisdictions using an effects-based approach, the claimant generally needs to demonstrate more than a linguistic difference: the conduct should have a plausible connection with competitive harm.

B. Discriminatory conditions

Where a dominant undertaking imposes different conditions on equivalent transactions, language-based differentiation can potentially be analysed as discriminatory treatment.

Typical examples include:

English-speaking suppliers receive immediate onboarding, whereas suppliers using another language face additional verification.

or:

Developers receive complete API documentation in one language but only incomplete documentation in another.

The important issue is whether the linguistic distinction produces a competitive disadvantage rather than merely a difference in convenience.

C. Refusal to deal or access

Language restrictions may also become relevant to a refusal-to-deal theory.

For example, suppose a dominant payment platform controls an important payment gateway and refuses access to a competing service because its documentation is not submitted in the platform's preferred language.

The analysis could involve:

1. indispensability;
2. elimination of effective competition;
3. inability to reasonably duplicate the facility;
4. discriminatory treatment; and
5. justification for the language requirement.

4. Objective Justification

A language requirement may be legitimate where there is a genuine connection with the service.

Possible legitimate reasons include:

• safety;
• consumer protection;
• technical accuracy;
• regulatory compliance;
• emergency communications;
• protection of confidential information;
• prevention of fraud;
• quality control;
• employee safety;
• judicial or administrative requirements.

For example, a hospital-information platform may legitimately require a particular language for emergency clinical instructions.

But a language requirement is more problematic where:

• translation is inexpensive;
• automated translation is technically feasible;
• the requirement is imposed only on rivals;
• equivalent information is readily available in multiple languages;
• the language has no relationship to the technical requirement; or
• the requirement unnecessarily prevents market participation.

5. Proportionality

The proportionality analysis can be divided into four questions.

1. Legitimate objective

What objective does the language restriction pursue?

2. Suitability

Can the language restriction actually achieve that objective?

3. Necessity

Could the same objective be achieved through a less restrictive method?

4. Balancing

Does the competitive harm substantially outweigh the legitimate benefit?

For example, requiring emergency-service operators to communicate in the local official language may be justified. Requiring an online marketplace's competing sellers to submit every ordinary commercial document exclusively in that language may be much harder to justify if inexpensive translation is available.

6. Relevant Case Laws

1. Anita Groener v Minister for Education and City of Dublin Vocational Educational Committee, Case C-379/87

This is an important foundational case concerning language requirements.

The Court of Justice accepted that a linguistic requirement could be justified where the objective was connected with the promotion of an official national language and the nature of the position genuinely required linguistic ability.

However, the requirement had to be applied in a proportionate and non-discriminatory manner.

Competition-law relevance

The case establishes an important principle:

Language requirements are not inherently discriminatory. Their legality depends upon their purpose, necessity and manner of application.

This is directly relevant when a dominant undertaking argues that a language restriction is required for quality, safety or effective service.

2. Roman Angonese v Cassa di Risparmio di Bolzano SpA, Case C-281/98

This case concerned a private bank that required candidates for employment to possess a bilingualism certificate issued by a particular local authority.

The Court held that a private undertaking could not restrict access to employment by requiring a certificate that could effectively be obtained only within a particular province.

Competition-law relevance

The case is significant because it demonstrates that private undertakings can create unlawful access barriers through apparently neutral language requirements.

A competition-law analogy arises where a dominant undertaking requires competitors or suppliers to possess a particular locally issued language certification even though equivalent linguistic competence can be demonstrated by other means.

3. Runevič-Vardyn and Wardyn, Case C-391/09

This case concerned the use of personal names in official documents and the relationship between language rules, nationality, free movement and equal treatment.

The Court examined Lithuanian rules requiring names to be recorded according to the conventions of the official national language.

Competition-law relevance

The case illustrates the distinction between:

• language regulation pursuing legitimate public objectives; and
• discriminatory treatment that lacks adequate justification.

For competition-law purposes, it supports careful examination of whether a linguistic rule is actually connected with a legitimate objective rather than simply disadvantaging outsiders.

4. Anton Las v PSA Antwerp NV, Case C-202/11

This is particularly useful for analysing language restrictions imposed upon commercial relationships.

Belgian regional legislation required employment documents involving an international employment relationship to be drafted in Dutch. The Court held that the requirement constituted a restriction on free movement and was disproportionate.

Competition-law relevance

The principle is highly transferable:

A language requirement imposed on an international commercial relationship can create a market-access barrier where it goes beyond what is necessary to protect the legitimate interest relied upon.

In a competition case, this can support scrutiny of language requirements imposed upon:

• cross-border suppliers;
• distributors;
• platform sellers;
• international contractors; and
• foreign competitors.

5. European Commission v Italian Republic, Case C-621/16 P

This case concerned EU recruitment competitions in which candidates were restricted in their choice of second language.

The Court held that differences in treatment based on language require objective justification and proportionality to the actual needs of the service. It also emphasized the need for clear, objective and predictable criteria supporting language requirements.

Competition-law relevance

Three principles are particularly useful:

1. language-based differentiation requires justification;
2. the justification must correspond to actual needs; and
3. the requirement must be objectively demonstrable.

For a competition authority, similar reasoning can be relevant when a dominant platform claims that a particular language restriction is necessary for technical or operational reasons.

6. Italian Republic v European Commission, Case T-437/16

The General Court considered a recruitment competition limiting the second language to English, French or German.

The Court recognized that restricting language choice could constitute discrimination, but such differentiation could potentially be justified where it corresponded to actual service requirements and satisfied proportionality.

Competition-law relevance

The case reinforces the necessity-and-evidence approach.

A dominant undertaking should not merely assert:

"Our system operates in English."

It may need to demonstrate why English is genuinely necessary and why less restrictive alternatives—such as translation, multilingual interfaces or equivalent documentation—would not adequately address the legitimate objective.

7. Spain v European Commission, Case T-554/19

The General Court annulled a competition notice that restricted the second language to four languages.

The dispute concerned recruitment in areas including competition law, financial law and economic and monetary union law. The Court applied the principles of language discrimination, service interests and proportionality.

Competition-law relevance

This case is especially interesting because the underlying recruitment areas included competition law itself.

It demonstrates that a language restriction must be supported by a sufficiently concrete explanation connecting the linguistic requirement with the actual functions to be performed.

8. French Republic v European Commission, Case T-555/22

In 2024, the General Court considered a competition whose second-language requirement was restricted to English and whose principal tests had to be taken in English.

The Court addressed the restriction under the principles of non-discrimination, linguistic diversity, service interests, proportionality and burden of proof.

Competition-law relevance

The case is useful for modern digital and international markets because it demonstrates that even a single-language requirement can require detailed justification.

The closer a language requirement comes to excluding otherwise capable market participants, the more important evidence of necessity becomes.

7. Application to Digital Platforms

Language access discrimination has become particularly significant in digital markets.

Consider a hypothetical dominant marketplace:

Platform A controls 80% of an online marketplace.

It provides:

• API documentation in English;
• seller verification in English;
• technical support in English;
• ranking appeals in English.

A competing seller using another language receives:

• delayed support;
• incomplete API documentation;
• additional verification;
• fewer dispute-resolution options.

The competition analysis would ask:

Step 1 — Is Platform A dominant?

Market share alone is not conclusive. Other factors include:

• network effects;
• switching costs;
• user data;
• entry barriers;
• multi-homing;
• ecosystem advantages.

Step 2 — Are the parties similarly situated?

The authority would compare equivalent sellers, developers or customers.

Step 3 — Does language produce unequal access?

The question is not simply whether different languages are used but whether the difference creates a material competitive disadvantage.

Step 4 — Is the requirement objectively justified?

Platform A might argue:

"English is required because our technical team operates in English."

That explanation would need to be examined against alternatives such as translation or multilingual technical documentation.

Step 5 — Does the conduct foreclose competition?

The authority would investigate whether the linguistic restriction:

• raises rivals' costs;
• reduces supplier participation;
• prevents entry;
• limits interoperability;
• reduces consumer choice; or
• strengthens the incumbent's network effects.

8. Language Access and Essential Facilities

Language discrimination becomes particularly significant when the relevant undertaking operates an essential facility.

Examples include:

• telecommunications interconnection;
• payment infrastructure;
• airport systems;
• electricity grids;
• rail infrastructure;
• dominant digital platforms;
• app stores;
• cloud infrastructure;
• identity systems;
• financial APIs.

Suppose an infrastructure operator provides access applications only in one language.

If the language requirement prevents otherwise qualified competitors from obtaining access, the authority may examine whether the requirement effectively operates as an access barrier.

The relevant distinction is:

language as a genuine technical requirement

versus

language as a mechanism for exclusion.

9. Language Discrimination and Interoperability

Interoperability problems can be especially serious.

A dominant messaging or payment platform might provide:

• API specifications;
• developer documentation;
• testing environments;
• security documentation;
• certification instructions

only in one language.

If competing providers cannot efficiently obtain this information, the language barrier can reinforce technical interoperability barriers.

The competition authority may therefore examine language restrictions together with:

• refusal to supply information;
• interoperability restrictions;
• discriminatory access;
• technical tying;
• self-preferencing; and
• exclusionary conduct.

10. Language Discrimination in Procurement

Public and private procurement can also raise competition concerns.

A tender may require bidders to submit:

"all technical documentation exclusively in Language X."

That requirement may be legitimate where:

• the project is safety-sensitive;
• local officials must operate the system;
• statutory rules require the language;
• emergency communications are involved.

But excessive requirements can reduce participation by foreign suppliers.

Competition concerns become stronger where:

• translation is readily available;
• the language has no technical relevance;
• the requirement is introduced shortly before bidding;
• incumbent suppliers already possess the required linguistic capability; or
• the requirement disproportionately excludes foreign competitors.

11. Language Access in Consumer Markets

Consumer-facing discrimination can also affect competition.

Examples include:

E-commerce

A marketplace provides refunds and dispute resolution only in one language.

Financial services

A dominant payment provider offers onboarding to merchants only in one language.

Telecommunications

A network operator provides important tariff and switching information only to customers using one language.

App stores

Developers must submit compliance documentation in a language that is not otherwise necessary for technical review.

Travel platforms

Hotels using particular languages receive better visibility or faster support.

In each situation, the competition question is whether language treatment affects market participation, competitive opportunity or consumer choice.

12. Direct vs Indirect Language Discrimination

Direct discrimination

The rule explicitly differentiates according to language.

Example:

"Only suppliers using English may participate."

This is straightforward linguistic differentiation.

Indirect discrimination

The rule is formally neutral but disproportionately disadvantages speakers of another language.

Example:

"All sellers must complete a technical examination within 30 minutes."

If the examination is available only in a particular language, the rule may have disproportionate effects despite appearing neutral.

Competition law would additionally ask whether those effects produce a meaningful competitive disadvantage.

13. Evidence Required to Establish the Concern

Important evidence can include:

Internal documents

• emails;
• compliance instructions;
• platform policies;
• management communications.

Access data

• rejection rates;
• onboarding times;
• suspension rates;
• complaint-resolution times.

Technical evidence

• API documentation;
• translation costs;
• interface architecture;
• language-support capabilities.

Economic evidence

• additional costs imposed on rivals;
• customer switching rates;
• supplier participation;
• foreclosure effects.

Comparative evidence

Whether equivalent services are available in multiple languages in competing markets.

14. Possible Defences

An undertaking accused of language discrimination may argue:

1. Regulatory compliance

The language is required by applicable legislation.

2. Safety

Miscommunication could cause significant harm.

3. Technical necessity

The system genuinely requires a particular language.

4. Consumer protection

The restriction ensures that customers understand important terms.

5. Fraud prevention

A common language is required for authentication or verification.

6. Cost efficiency

Supporting multiple languages may be expensive.

However, cost alone will not necessarily justify exclusionary conduct by a dominant undertaking, particularly where lower-cost alternatives exist.

15. Remedies

If competition authorities establish unlawful discriminatory conduct, possible remedies can include:

Structural or access remedies

• opening access;
• eliminating discriminatory conditions;
• allowing equivalent certification.

Behavioural remedies

• multilingual documentation;
• equal API access;
• standardized onboarding;
• non-discriminatory support.

Transparency remedies

• publishing objective language requirements;
• explaining rejection decisions;
• providing appeal mechanisms.

Technical remedies

• multilingual interfaces;
• translation layers;
• standardized APIs;
• interoperable data formats.

Monitoring

Authorities may require:

• periodic compliance reports;
• access statistics;
• complaint data;
• independent audits.

16. Key Legal Principles from the Cases

17. China Competition-Law Perspective

In China, language access discrimination should generally be analysed through the Anti-Monopoly Law (AML) rather than treating language itself as an independent competition offence.

Potentially relevant provisions include:

• abuse of a dominant market position;
• discriminatory transaction conditions;
• refusal to deal;
• exclusionary conduct;
• unfair trading conditions; and
• conduct restricting competition in digital markets.

A language requirement would therefore become a competition issue where it is used by a dominant enterprise to exclude competitors, discriminate among trading partners, increase rivals' costs or restrict market access.

For example, a dominant digital platform could potentially attract scrutiny if it:

1. permits domestic suppliers to use several languages;
2. imposes substantially greater language requirements on foreign or rival suppliers;
3. controls an important distribution channel;
4. provides faster technical access to favoured suppliers; and
5. uses the language requirement to reinforce its market position.

The critical question would remain whether the language distinction is objectively justified and competitively necessary.

18. Hypothetical Example

Assume Company X operates the dominant logistics platform in a country.

It provides API access to logistics companies.

English-speaking company

• API documentation: complete;
• onboarding: 2 days;
• technical support: 24 hours;
• certification: online.

Non-English-speaking company

• incomplete API documentation;
• manual application;
• onboarding: 30 days;
• no technical support in its language;
• additional certification.

Company X argues:

"English is the working language of our engineers."

The competition authority would investigate:

1. whether Company X is dominant;
2. whether the applicants are similarly situated;
3. whether the language requirement is genuinely necessary;
4. whether translation is feasible;
5. whether the differential treatment is consistently applied;
6. whether the policy increases rivals' costs;
7. whether competitors have been excluded or delayed;
8. whether consumers lose choice; and
9. whether less restrictive alternatives exist.

If the language requirement is merely a convenient method of disadvantaging competitors, the competition concern is considerably stronger than where language is genuinely necessary for safety or technical compatibility.

19. Conclusion

Language access discrimination becomes a competition-law problem when language restrictions operate as a mechanism for unequal market access or competitive foreclosure.

The principal legal lesson from the case law is that language requirements are not inherently prohibited. Courts generally distinguish legitimate language requirements from disproportionate restrictions.

The most important analytical questions are:

1. Who controls access?
2. What market power does that undertaking possess?
3. Who is disadvantaged by the language requirement?
4. Are the affected parties similarly situated?
5. What legitimate objective is being pursued?
6. Is the language requirement necessary to achieve that objective?
7. Could translation or another less restrictive mechanism achieve the same result?
8. Does the conduct increase rivals' costs or foreclose competitors?
9. Does it reduce consumer choice or market participation?
10. Is the requirement transparent, consistently applied and proportionate?

Accordingly, the central competition-law principle can be stated as:

A linguistic distinction becomes particularly problematic where a firm with substantial market power uses language requirements not as a genuine operational necessity, but as a means of restricting access, discriminating among trading partners, or weakening actual or potential competitors.

The leading authorities for this analysis include Groener, Angonese, Runevič-Vardyn and Wardyn, Las, Commission v Italy, Italian Republic v Commission, Spain v Commission, and French Republic v Commission.
