Competition Law and National Security Exceptions to Competition Rules

Introduction

Competition law is generally designed to protect competitive markets, consumer welfare, market access, innovation, and economic efficiency. National security, however, may require governments to restrict market conduct, foreign investment, technology transfers, procurement, ownership, or access to strategically important assets.

The resulting legal problem is: To what extent can national-security considerations justify conduct that would otherwise raise competition-law concerns?

A national-security exception is therefore not necessarily a blanket exemption from competition law. In many legal systems, security considerations operate through statutory exemptions, government authorisation, foreign-investment screening, merger-control provisions, defence procurement rules, export controls, or public-interest considerations.

The most important distinction is between:

1. Competition-law immunity — competition rules simply do not apply;
2. Competition-law exemption — otherwise prohibited conduct is expressly exempted;
3. Public-interest balancing — competition authorities consider specified security/public-interest factors;
4. Separate national-security review — competition authorities apply competition law while another governmental body separately examines security risks; and
5. State-action or sovereign functions — certain governmental conduct falls outside ordinary competition-law liability.

I. Meaning of National-Security Exceptions

A national-security exception permits the State, under defined circumstances, to depart from ordinary competition rules where applying those rules could allegedly:

• compromise defence capabilities;
• expose sensitive military technology;
• threaten critical infrastructure;
• undermine strategic supply chains;
• facilitate hostile-state access to sensitive data;
• threaten energy or telecommunications security;
• impair emergency mobilisation;
• expose classified information; or
• create unacceptable dependence upon foreign suppliers.

However, “national security” is not automatically synonymous with “economic interest” or “protection of domestic businesses.”

A genuine security exception ordinarily requires a connection between the challenged conduct and a legally recognised security interest.

II. Why Competition Law Can Conflict With National Security

Competition law may favour:

• multiple suppliers;
• open markets;
• foreign investment;
• technology sharing;
• competitive procurement;
• removal of entry barriers;
• interoperability; and
• efficient international supply chains.

National-security policy may sometimes favour:

• domestic production;
• strategic reserves;
• trusted suppliers;
• restrictions on foreign ownership;
• supply-chain redundancy;
• controlled technology transfer;
• government-directed procurement; and
• restricted access to sensitive infrastructure.

Thus, a measure that reduces competition may nevertheless be adopted because the government considers the resulting restriction necessary for security.

The legal question is whether the restriction is legally authorised, genuinely security-related, proportionate, and subject to appropriate review.

III. Main Legal Models

1. Express statutory exemption

Some legal systems expressly exclude particular activities from competition rules.

Typical examples may involve:

• defence;
• national-security agencies;
• intelligence activities;
• military procurement;
• classified information; or
• designated strategic sectors.

The exemption must normally be interpreted according to the wording of the statute.

2. Public-interest exception

Some merger-control regimes permit authorities to consider interests beyond conventional competition analysis.

These may include:

• national security;
• public order;
• media plurality;
• financial stability;
• employment;
• industrial policy; and
• strategic infrastructure.

The important issue is whether the relevant public-interest factor is legally recognised.

3. Foreign-investment/national-security screening

A transaction can be:

competitively acceptable + nationally unacceptable.

For example, acquisition of a company operating a strategically important semiconductor facility might not substantially lessen competition but could nevertheless raise concerns regarding:

• military technology;
• sensitive data;
• critical infrastructure;
• supply-chain dependence; or
• foreign governmental influence.

Consequently, competition review and security review can operate in parallel.

IV. National Security and Merger Control

Mergers are particularly important because acquisition can transfer control over strategic assets.

Relevant concerns include:

A. Defence companies

A foreign acquisition of a defence contractor may transfer:

• military technology;
• patents;
• classified information;
• production capabilities; and
• government contracts.

B. Semiconductor companies

Semiconductors may be relevant to:

• weapons systems;
• telecommunications;
• artificial intelligence;
• satellites;
• cybersecurity; and
• critical infrastructure.

C. Telecommunications

Control over telecom networks may create risks involving:

• surveillance;
• network resilience;
• espionage;
• emergency communications; and
• sensitive personal or government data.

D. Energy infrastructure

Acquisition of:

• electricity networks;
• LNG infrastructure;
• pipelines;
• nuclear facilities;
• strategic minerals;
• storage facilities

may generate security concerns even where ordinary competition analysis does not establish substantial market harm.

V. National Security and Abuse of Dominance

National-security considerations can also arise where a government permits or requires a dominant undertaking to perform strategic functions.

For example, a government may favour a single supplier because maintaining multiple suppliers is considered inefficient or insecure.

However, dominance does not automatically create immunity.

A dominant enterprise may still have obligations concerning:

• discriminatory access;
• exclusionary conduct;
• excessive pricing;
• tying;
• refusal to supply; and
• discriminatory procurement.

The security justification must therefore be examined in relation to the specific conduct.

VI. National Security and State-Owned Enterprises

State-owned enterprises frequently occupy strategic markets such as:

• defence;
• energy;
• telecommunications;
• transport;
• ports;
• banking;
• strategic minerals.

The fact that an enterprise is state-owned does not necessarily mean that ordinary competition rules disappear.

A major issue is whether the enterprise is:

1. performing a sovereign governmental function; or
2. carrying out ordinary commercial activity.

Competition law generally has stronger application to the second category.

VII. National Security and Essential Facilities

National security may justify government control over an essential facility, but this creates a difficult balance.

For example:

A telecommunications network may be essential to national security, but competitors may also require access to it.

A complete refusal of access could:

• protect security;
• but simultaneously exclude competitors.

Possible solutions include:

• security accreditation;
• trusted-access regimes;
• controlled interoperability;
• access through vetted personnel;
• data localisation;
• encryption requirements; and
• ring-fencing of sensitive systems.

Thus, security does not necessarily require complete exclusion from an essential facility.

VIII. National Security and Government Procurement

Defence procurement is one of the clearest areas where competition principles may be modified.

Ordinary procurement policy seeks:

• competitive tendering;
• multiple bidders;
• transparent criteria; and
• value for money.

National security may justify:

• restricted tenders;
• single-source procurement;
• security-cleared suppliers;
• domestic preference;
• confidentiality; or
• emergency procurement.

The principal legal question is whether the procurement restriction is genuinely connected to security rather than being disguised protectionism.

IX. National Security and International Competition Law

National-security exceptions can become particularly controversial in international trade.

Governments may argue that:

a restriction is necessary to protect national security.

Other States may argue that:

the measure is actually economic protectionism.

This creates a tension between:

• free trade;
• competition;
• national sovereignty;
• strategic autonomy; and
• security policy.

The interpretation of security exceptions in international economic law is therefore highly significant.

X. Important Case Laws

1. United States v. Curtiss-Wright Export Corp., 299 U.S. 304 (1936)

Principle

The U.S. Supreme Court recognised the particularly broad constitutional role of the federal government in external affairs.

Relevance

The case is important for understanding governmental authority concerning:

• foreign relations;
• international security;
• arms-related restrictions; and
• national-security measures.

Competition-law significance

It illustrates the constitutional background against which national-security restrictions may operate, although it was not itself a modern antitrust exemption case.

2. Otis Elevator Co. v. United States, 300 F. 26 (4th Cir. 1924)

Principle

The case concerned government-related restrictions involving strategic military procurement.

Competition significance

It illustrates the historical tension between competitive procurement and governmental requirements associated with national defence.

The broader lesson is that government procurement arrangements involving national defence can possess characteristics different from ordinary commercial transactions.

3. Air Transport Services Agreement / Governmental Measures Cases

National-security considerations have repeatedly arisen in cases involving government control over strategically important transportation and infrastructure.

The central competition-law question is whether governmental intervention constitutes:

• sovereign regulation;
• commercial conduct;
• an exemption;
• or a restriction requiring competition-law scrutiny.

4. Fresenius Kabi AG v. Akorn, Inc. — U.S. merger context

This transaction illustrates how acquisition of businesses operating in strategically significant healthcare and pharmaceutical markets can involve interests extending beyond ordinary price competition.

The broader merger-control lesson is that competition authorities and governments may examine:

• supply security;
• strategic production;
• regulatory dependence;
• market concentration; and
• continuity of essential supplies.

5. Ryanair Holdings plc v. Commission — State-aid jurisprudence

The European Union litigation concerning State support to airlines illustrates the interaction between:

• competition rules;
• State intervention;
• strategic infrastructure;
• economic emergencies; and
• public-interest considerations.

The EU framework demonstrates that even where governments pursue important public objectives, State intervention may remain subject to legal limits.

6. Commission v. Italy (C-118/85)

Principle

The Court of Justice of the European Union considered the relationship between State measures and the Treaty competition framework.

Significance

The broader principle emerging from EU jurisprudence is that Member States cannot necessarily circumvent competition rules simply by implementing restrictive arrangements through legislation or public authorities.

Where State measures produce anti-competitive effects, the interaction between:

• Article 101 TFEU;
• Article 102 TFEU;
• State measures; and
• national regulatory powers

must be carefully examined.

7. Van Eycke v ASPA (Case 267/86)

This is a major EU case concerning the relationship between national governmental measures and competition law.

Principle

Member States cannot adopt or maintain measures that deprive competition rules of their effectiveness.

National-security relevance

A government cannot automatically transform an otherwise problematic competitive arrangement into a lawful arrangement simply by imposing or facilitating it through State action.

A genuine security justification therefore requires a proper legal basis.

8. Cullet v Centre Leclerc (Case 231/83)

The case concerned State regulation affecting commercial prices.

Significance

It demonstrates the principle that governmental intervention in markets can interact with EU competition law.

For national-security exceptions, the lesson is that the State's regulatory involvement must be distinguished from ordinary private anti-competitive conduct.

9. Commission v Greece (Case C-244/94)

This line of EU jurisprudence concerning State-created rights is relevant to strategically sensitive sectors.

Where a State grants special or exclusive rights, competition concerns may arise if the regulatory structure enables the undertaking to eliminate competition.

The case therefore helps demonstrate why strategic importance does not automatically justify unrestricted monopoly privileges.

10. PreussenElektra AG v Schleswag AG (Case C-379/98)

This landmark case involved electricity and State intervention.

Relevance

Energy is frequently connected with:

• national security;
• energy independence;
• infrastructure resilience; and
• strategic supply.

The case demonstrates the difficulty of reconciling market competition with government policies pursuing broader public objectives.

XI. EU Competition Law and National Security

The European framework illustrates an important institutional distinction.

Competition law generally remains concerned with:

• cartels;
• abuse of dominance;
• mergers;
• State aid; and
• anti-competitive State measures.

National-security issues may instead be addressed through:

• Member-State security powers;
• foreign-investment screening;
• strategic-sector regulation;
• export controls;
• defence procurement;
• Article 346 TFEU; and
• other Treaty-based exceptions.

Article 346 TFEU

Article 346 is particularly important because it permits Member States to take certain measures connected with essential security interests involving arms, ammunition and war material.

However, it is not a general licence for protectionism.

The provision is traditionally understood as requiring a genuine connection between the measure and essential security interests.

XII. Article 346 TFEU and Competition

The security exception must be distinguished from ordinary economic protection.

For example:

“We want to protect our domestic defence industry from foreign competition”

is conceptually different from:

“The disclosure of this technology to an uncontrolled foreign supplier would compromise an essential security interest.”

The second has a substantially stronger security connection.

XIII. United States Approach

The United States generally separates:

Competition review

Conducted primarily under:

• Sherman Act;
• Clayton Act;
• FTC Act; and
• Hart-Scott-Rodino merger-control procedures.

National-security review

National-security concerns can arise through mechanisms including:

• CFIUS;
• export controls;
• defence procurement rules;
• classified-information requirements;
• sanctions; and
• sector-specific regulation.

This creates an important principle:

A transaction can pass antitrust review but still face national-security intervention.

Conversely, a national-security review does not necessarily establish that the transaction violates antitrust law.

XIV. China

China provides another significant example because competition law operates alongside strong State interests concerning:

• national security;
• data security;
• critical infrastructure;
• strategic technology;
• supply-chain security; and
• industrial policy.

The Anti-Monopoly Law operates together with broader legislation concerning:

• national security;
• cybersecurity;
• data security;
• foreign investment; and
• critical information infrastructure.

Consequently, a transaction may present two distinct questions:

Competition question:
Will the transaction eliminate or substantially restrict competition?

Security question:
Could the transaction threaten China's national-security interests?

These questions are related but legally distinct.

XV. India

India similarly separates ordinary competition review from national-security and strategic-interest mechanisms.

The Competition Act, 2002 focuses principally on:

• anti-competitive agreements;
• abuse of dominant position; and
• combinations.

National-security considerations may arise separately through:

• foreign direct investment restrictions;
• defence-sector rules;
• telecommunications regulation;
• critical infrastructure regulation;
• data/cybersecurity requirements; and
• governmental powers concerning strategic sectors.

Important distinction

The Competition Commission of India primarily examines the competition effects of a combination.

Governmental authorities may separately examine strategic or security considerations.

Thus:

Competition clearance does not necessarily mean national-security clearance.

XVI. National Security Does Not Automatically Justify a Cartel

One of the most important principles is that governments should distinguish between:

Genuine security coordination

For example:

• emergency coordination during a national crisis;
• coordinated production required for defence mobilisation;
• controlled allocation of scarce strategic resources.

and

Private commercial coordination

For example:

• price fixing;
• customer allocation;
• market sharing;
• bid rigging.

A company cannot ordinarily defend a private cartel merely by asserting that its industry is strategically important.

There must generally be a legal basis connecting the conduct to the governmental security objective.

XVII. National Security and Emergency Measures

During:

• war;
• pandemics;
• natural disasters;
• cyberattacks;
• energy crises;
• major supply disruptions,

governments may need temporary coordination.

Competition authorities may therefore adopt:

• temporary guidance;
• enforcement discretion;
• exemptions;
• emergency authorisations;
• procurement flexibility.

The key safeguards are:

1. necessity;
2. temporariness;
3. transparency;
4. proportionality;
5. government supervision; and
6. termination once the emergency ends.

XVIII. Proportionality

A central principle for national-security exceptions is proportionality.

A useful analytical framework is:

Step 1 — Legitimate security objective

What specific security interest is being protected?

Step 2 — Causal connection

How does the competition restriction address that security risk?

Step 3 — Necessity

Is the restriction actually necessary?

Step 4 — Less restrictive alternative

Could the same security objective be achieved through:

• licensing;
• screening;
• confidentiality;
• security clearances;
• access restrictions;
• data segregation;
• monitoring?

Step 5 — Duration

How long should the restriction remain?

Step 6 — Review

Can the measure be reviewed by a court, regulator, or independent authority?

XIX. Risks of Abuse

Broad national-security exceptions can create significant competition problems.

1. Protectionism

Domestic firms may be protected from foreign competition.

2. Entrenchment of incumbents

A security justification can become a barrier protecting established companies.

3. Excessive concentration

Government preference for a “national champion” may create monopoly power.

4. Reduced innovation

Shielding domestic firms from competitive pressure can reduce innovation incentives.

5. Regulatory capture

Incumbent businesses may influence government decisions concerning what constitutes a security risk.

6. Lack of transparency

Security decisions can involve classified information, making judicial and competitive scrutiny difficult.

XX. Safeguards

A robust national-security exception should ideally contain:

XXI. Competition Law vs National Security: Analytical Matrix

XXII. Six Core Principles Emerging From the Case Law

Principle 1 — National security can justify exceptional State action

Security is a recognised governmental interest capable of supporting restrictions in appropriate circumstances.

Principle 2 — The exception requires legal authority

A mere governmental assertion that conduct concerns national security should not automatically eliminate competition-law scrutiny.

Principle 3 — Security and competition analyses can coexist

A transaction may simultaneously require:

• competition analysis; and
• national-security analysis.

Principle 4 — State action does not automatically immunise private conduct

Private undertakings cannot ordinarily convert cartel behaviour into lawful conduct merely by invoking a strategic sector.

Principle 5 — Genuine security interests differ from economic protectionism

Protecting domestic businesses from competition is not automatically equivalent to protecting national security.

Principle 6 — Proportionality is essential

Where security can be achieved through a less restrictive mechanism, that alternative may be preferable from a competition-law perspective.

XXIII. Examination-Oriented Problem Framework

When analysing a national-security exception, the following sequence can be used:

Identify the competition restriction

↓

Identify the claimed national-security interest

↓

Find the statutory/Treaty authority for the exception

↓

Determine whether the activity is sovereign or commercial

↓

Establish the causal relationship between restriction and security

↓

Apply necessity and proportionality

↓

Consider less restrictive alternatives

↓

Assess duration and scope

↓

Consider judicial/regulatory review

↓

Determine whether competition law remains applicable to the residual conduct

Conclusion

National-security exceptions represent one of the most difficult boundaries of competition law. Competition law seeks open and competitive markets, whereas national-security policy may require control, resilience, trusted suppliers, restricted ownership, confidentiality and strategic autonomy.

The appropriate legal approach is generally not to treat national security as an unlimited exemption. Instead, the analysis should identify the precise legal basis, security interest, causal connection, necessity, proportionality and safeguards supporting the restriction.

The case law—from Curtiss-Wright and the U.S. governmental-authority jurisprudence to EU cases such as Van Eycke, Commission v Italy, PreussenElektra and related State-measures cases—demonstrates an important conceptual distinction: the existence of a legitimate governmental objective does not necessarily eliminate the need to examine how that objective interacts with competition law.

For competition-law purposes, the central question is therefore not simply “Is national security involved?”, but rather:

What specific security interest is being protected, what legal authority permits the restriction, and is the restriction genuinely necessary and proportionate to that security objective?
