Competition Law and Access to Infrastructure Facilities

1. Introduction

Access to infrastructure facilities is an important competition-law issue where an infrastructure owner controls a facility that competitors need in order to operate effectively in a market.

Infrastructure may include:

• Railways and railway tracks
• Ports and port terminals
• Airports and airport facilities
• Electricity transmission and distribution networks
• Gas pipelines
• Telecommunications networks
• Payment and clearing infrastructure
• Digital platforms and technical interfaces
• Essential data or network infrastructure
• Water and sewage networks
• Warehouses, logistics facilities and transport terminals

The competition concern arises when a dominant infrastructure operator refuses access, discriminates between users, imposes unreasonable conditions, charges excessive or discriminatory access fees, or makes access technically impossible.

The central legal question is:

When does control over an important infrastructure facility create a competition-law obligation to provide access to competitors?

The answer depends heavily on the jurisdiction, the nature of the facility, the degree of market power, the availability of alternatives, and whether sector-specific regulation already governs access.

2. Meaning of Infrastructure Facilities

An infrastructure facility is generally a physical, technical or network-based facility that is necessary or highly important for supplying goods or services.

Examples include:

Physical infrastructure

• Railway tracks
• Ports
• Airports
• Electricity grids
• Gas pipelines
• Telecommunications towers
• Freight terminals

Network infrastructure

• Telecommunications networks
• Payment networks
• Internet backbone infrastructure
• Energy transmission systems
• Digital communications systems

Digital infrastructure

• Operating-system interfaces
• App distribution systems
• Cloud infrastructure
• Digital identity systems
• Data-access infrastructure
• Interoperability interfaces

Not every important facility is legally an essential facility. Competition law normally requires a stronger showing of necessity and competitive harm.

3. Essential Facilities Doctrine

The essential facilities doctrine concerns situations where a dominant undertaking controls a facility that competitors cannot reasonably reproduce or replace.

The doctrine is particularly associated with refusal-to-deal cases.

A simplified structure is:

1. The undertaking controls the facility.
2. The facility is necessary for competitors to operate.
3. Duplication is technically, legally or economically impracticable.
4. Access can be provided without eliminating the legitimate operation of the facility.
5. Refusal causes competitive harm.
6. There is no adequate objective justification for the refusal.

However, courts have generally been cautious because forcing a company to share its infrastructure can interfere with property rights, investment incentives and business freedom.

4. Refusal of Access as an Abuse of Dominance

Under competition law, refusal to provide access can become abusive where the infrastructure owner has a dominant position and the refusal excludes competitors.

The legal analysis usually examines:

A. Dominance

The infrastructure operator must ordinarily possess substantial market power.

Factors include:

• Market share
• Control over infrastructure
• Barriers to entry
• Network effects
• Switching costs
• Availability of alternatives
• Regulation
• Financial and technological barriers to duplication

B. Necessity

The facility must generally be more than merely convenient.

The competitor should demonstrate that access is necessary to compete effectively.

C. Lack of alternatives

If competitors can reasonably construct their own infrastructure or use another facility, competition law is less likely to require compulsory access.

D. Elimination or substantial restriction of competition

The refusal should have meaningful effects on competition rather than merely harming an individual competitor.

E. Objective justification

The infrastructure owner may have legitimate reasons for refusing access, including:

• Capacity limitations
• Safety requirements
• Technical incompatibility
• Security concerns
• Protection of network integrity
• Insufficient capacity
• Regulatory restrictions
• Legitimate commercial considerations

5. Key Case Laws

1. Commercial Solvents Corp. v Commission

Cases: Joined Cases 6/73 and 7/73, Instituto Chemioterapico Italiano S.p.A. and Commercial Solvents Corporation v Commission

Facts

Commercial Solvents controlled an important raw material used by another company for producing pharmaceutical products.

After deciding to enter the downstream market itself, Commercial Solvents restricted the supply of the raw material to its downstream competitor.

Legal issue

Could a dominant undertaking controlling an essential input restrict supply in order to favour its own downstream operations?

Principle

The European Court held that a dominant undertaking controlling an important input could not use that control to eliminate a downstream competitor where the supply was necessary for that competitor's business.

Importance

The case established an early foundation for the principle that a dominant undertaking cannot use control over an essential input to foreclose downstream competition.

Although the case involved an input rather than a traditional physical infrastructure facility, its reasoning became important for later refusal-to-supply and essential-facility cases.

6. United Brands v Commission

Case: Case 27/76, United Brands Company and United Brands Continentaal BV v Commission

Facts

United Brands was a major banana supplier. It imposed restrictions concerning distributors and refused to supply certain customers.

Legal issue

Whether a dominant undertaking could use its commercial control over an important distribution system to restrict competition.

Principle

The Court confirmed that a dominant undertaking has a special responsibility not to allow its conduct to undermine genuine competition.

The case is especially important for the broader principle that conduct by a dominant firm must be examined in light of its effects on market competition.

Relevance to infrastructure access

Where an infrastructure operator controls an indispensable distribution channel, discriminatory or exclusionary access conditions can raise similar concerns.

7. Oscar Bronner GmbH v Mediaprint

Case: C-7/97, Oscar Bronner GmbH & Co. KG v Mediaprint Zeitungs und Zeitschriftenverlag GmbH & Co. KG

Facts

Oscar Bronner operated a newspaper that wanted access to Mediaprint's newspaper home-delivery system.

Mediaprint operated a large delivery network that competing newspapers could potentially use.

Legal issue

Was Mediaprint required under EU competition law to allow a competing newspaper to use its distribution network?

Principle

The Court adopted a strict approach to compulsory access.

A refusal to supply is not automatically abusive merely because access would help a competitor.

The facility must be genuinely indispensable, and there must generally be no real or potential alternative that could reasonably substitute for it.

The Court also considered whether duplication of the facility was economically or technically feasible.

Importance

Bronner is one of the leading cases on essential facilities.

It establishes that competition law should not casually convert a private infrastructure owner into a compulsory supplier.

8. IMS Health v Commission

Case: C-418/01 P, IMS Health GmbH & Co. OHG v NDC Health GmbH & Co. KG

Facts

IMS Health controlled a particular data structure used for pharmaceutical sales information.

A competitor needed access to the structure to compete effectively.

Legal issue

Could refusal to license an intellectual-property-related infrastructure become an abuse of dominance?

Principle

The Court identified strict conditions for compulsory access involving intellectual property.

The refusal could potentially be abusive where:

1. Access is indispensable.
2. Refusal prevents the emergence of a new product or service for which consumer demand exists.
3. Refusal is unjustified.
4. The refusal reserves a secondary market to the dominant undertaking.

Importance

The case demonstrates that the essential-facility concept is not limited to physical infrastructure.

It can also involve technical systems, information structures and intellectual-property-related infrastructure.

9. Slovak Telekom v Commission

Cases: Joined Cases C-165/19 P and C-166/19 P

Facts

Slovak Telekom operated telecommunications infrastructure and was subject to obligations concerning access to its network.

The European Commission found that its conduct concerning access and pricing could restrict competition.

Legal issue

How should competition law apply where a dominant infrastructure operator is already subject to sector-specific access regulation?

Principle

The case is important because the Court distinguished between:

• ordinary refusal-to-deal situations, and
• situations where an undertaking is already subject to a regulatory obligation to provide access.

Where regulation requires access, competition authorities may examine whether the undertaking uses the access obligation in an exclusionary manner.

Importance

The case demonstrates the interaction between:

sector regulation + competition law + infrastructure access.

Telecommunications operators cannot necessarily rely on the general freedom to refuse dealings where regulatory rules already require network access.

10. Baltic Rail / Lietuvos geležinkeliai

Case: C-117/17 P, Lietuvos geležinkeliai AB v European Commission

Facts

Lietuvos geležinkeliai operated railway infrastructure in Lithuania.

A competitor sought to use railway infrastructure to provide competing rail services.

A railway track was removed, affecting the competitor's ability to use an alternative route.

Legal issue

Could the removal of infrastructure constitute an abuse of dominance?

Principle

The case is particularly important for infrastructure competition because it concerns the strategic use of railway infrastructure.

The Court confirmed that the deliberate removal of infrastructure can raise Article 102 concerns where it forms part of exclusionary conduct by a dominant infrastructure operator.

Importance

It illustrates that an infrastructure abuse does not always take the form of an express refusal.

Competition concerns may arise from:

• physical removal,
• degradation,
• restriction,
• technical obstruction, or
• strategic modification

of infrastructure.

11. Port of Genoa / Merci Convenzionali Porto di Genova

Case: C-179/90, Merci Convenzionali Porto di Genova SpA v Siderurgica Gabrielli SpA

Facts

The case concerned port services and the relationship between exclusive rights and competition.

Legal issue

Whether exclusive rights relating to port operations could conflict with EU competition principles.

Principle

The Court examined the relationship between:

• exclusive rights,
• state measures,
• dominant positions, and
• competition.

Importance

Ports are classic examples of infrastructure where duplication may be extremely expensive or practically impossible.

The case therefore provides important background for understanding competition rules concerning essential transport infrastructure.

12. Deutsche Telekom v Commission

Case: C-280/08 P, Deutsche Telekom AG v Commission

Facts

Deutsche Telekom controlled telecommunications infrastructure and charged wholesale and retail prices that resulted in a margin squeeze for competitors.

Legal issue

Could a dominant infrastructure operator violate competition law even when its prices were subject to regulatory oversight?

Principle

The Court confirmed that regulatory supervision does not automatically immunise a dominant undertaking from EU competition law.

A dominant infrastructure operator can still be responsible for exclusionary pricing conduct.

Importance

Infrastructure access therefore involves more than simply deciding whether access is technically available.

Competition authorities may also examine:

• access prices,
• wholesale conditions,
• retail prices,
• margin squeeze,
• discrimination,
• technical restrictions.

13. Common Legal Principles from the Cases

The cases show several recurring principles.

14. Infrastructure Access and Discrimination

A dominant infrastructure operator may technically provide access while still restricting competition through discriminatory conditions.

For example:

Company A owns the only major railway terminal in a region.

It allows its own subsidiary to use the terminal at favourable times and charges competitors higher fees or gives them less favourable slots.

The legal question is not simply:

“Was access provided?”

It is also:

“Was access provided on genuinely equivalent competitive terms?”

Possible discriminatory conduct includes:

• Different access prices
• Different quality of service
• Different operating hours
• Preferential scheduling
• Priority capacity
• Different technical standards
• Delayed connection
• Selective maintenance
• Discriminatory security requirements
• Unreasonable documentation requirements

15. Access Pricing

Pricing is another major competition concern.

Suppose an infrastructure owner charges competitors:

• ₹100 per unit to access its infrastructure,

while charging its own downstream subsidiary:

• ₹20 per unit.

Even where the difference has an objective explanation, the competition authority may investigate whether the pricing creates an exclusionary advantage.

Relevant questions include:

1. Are the costs genuinely different?
2. Is the pricing transparent?
3. Are comparable users treated equally?
4. Does the price prevent efficient competitors from operating?
5. Is the price regulated?
6. Does the infrastructure operator compete downstream?

16. Margin Squeeze

A particularly important infrastructure problem is margin squeeze.

This occurs when a vertically integrated infrastructure owner:

1. controls an essential upstream facility;
2. supplies access to competitors; and
3. competes against those competitors downstream.

For example:

Infrastructure owner

↓ wholesale access

Competitor

↓ retail service

At the same time, the infrastructure owner sells its own retail service.

If the wholesale access price is sufficiently high while the infrastructure owner's retail price is sufficiently low, an equally efficient competitor may be unable to earn a viable margin.

This was central to the reasoning in Deutsche Telekom.

17. Vertical Integration and Self-Preferencing

Infrastructure access becomes especially sensitive when the infrastructure owner also operates downstream.

For example:

A company owns the only major payment infrastructure and also provides payment services to consumers.

It may have an incentive to:

• delay competitors,
• give its own services priority,
• provide competitors with inferior technical access,
• charge competitors higher fees,
• restrict data,
• impose interoperability conditions.

Competition law therefore pays particular attention to vertical foreclosure.

18. Sector-Specific Regulation

Competition law frequently operates alongside sector-specific regulation.

Important regulated sectors include:

Telecommunications

Network access and interoperability.

Electricity

Transmission and distribution access.

Gas

Pipeline access.

Railways

Track access and terminal access.

Ports

Terminal and port-service access.

Airports

Slots, terminals and essential airport services.

Financial markets

Payment, clearing and settlement infrastructure.

Digital markets

Interoperability, data access and technical interfaces.

Sector regulation may establish:

• access rights,
• access tariffs,
• non-discrimination rules,
• technical standards,
• capacity allocation mechanisms,
• transparency requirements.

Competition law can then address conduct that goes beyond ordinary regulatory compliance.

19. Essential Facility vs Ordinary Commercial Facility

This distinction is critical.

Ordinary commercial facility

A competitor wants access because it is cheaper or more convenient.

Competition law will generally be reluctant to force the owner to provide access.

Essential facility

The competitor cannot realistically operate without access.

The case for compulsory access becomes considerably stronger.

Example

If three independent warehouses operate in the market, refusal by one warehouse is unlikely to create an essential-facility problem.

But if a port has the only technically suitable deep-water terminal for a particular type of cargo, access may raise much more serious competition concerns.

20. Objective Justification

A refusal may be legitimate when there is a genuine objective reason.

Examples include:

Capacity constraints

There may simply be insufficient capacity.

Safety

Access may create unacceptable safety risks.

Technical incompatibility

The competitor's equipment may not satisfy technical standards.

Security

Critical infrastructure may require security restrictions.

Network integrity

Access could interfere with the functioning of the network.

Investment protection

The infrastructure operator may argue that compulsory access would undermine incentives to invest.

Legal restrictions

The operator may be legally prohibited from providing access.

The justification must be genuine and proportionate rather than merely a pretext for excluding competitors.

21. Economic Rationale Behind the Doctrine

Competition law faces a difficult balance.

If access is too easy to obtain

Companies may have weaker incentives to:

• build infrastructure,
• invest in networks,
• innovate,
• expand capacity.

If access is too difficult to obtain

Infrastructure owners may be able to:

• exclude competitors,
• preserve monopolies,
• increase prices,
• prevent market entry,
• favour their own downstream businesses.

The essential-facilities framework therefore attempts to balance:

competition + investment incentives + property rights + consumer interests.

22. Remedies for Unlawful Infrastructure Restrictions

Competition authorities or courts may impose several remedies.

1. Mandatory access

The dominant operator may be required to provide access.

2. Non-discriminatory access

Comparable competitors must receive equivalent conditions.

3. Price regulation

Access prices may be subject to competition-law or sector-regulatory controls.

4. Transparency

The operator may be required to publish:

• tariffs,
• technical requirements,
• capacity information,
• access procedures.

5. Interoperability

The operator may have to provide technical interfaces enabling competitors to connect.

6. Structural remedies

In exceptional situations, separation between infrastructure and downstream activities may be considered.

7. Financial penalties

Competition authorities may impose fines for abusive conduct.

23. Application to Digital Infrastructure

The concept is increasingly important in digital markets.

Potential infrastructure facilities include:

• app stores,
• operating systems,
• payment interfaces,
• cloud platforms,
• digital identity systems,
• search infrastructure,
• data-access systems,
• interoperability interfaces.

A digital infrastructure owner may potentially restrict competition by:

• denying API access,
• limiting interoperability,
• withholding technical information,
• restricting data portability,
• imposing discriminatory technical requirements,
• favouring its own downstream service.

The traditional essential-facilities doctrine can therefore intersect with newer rules concerning digital gatekeepers, interoperability and data access.

24. Difference Between Refusal to Deal and Discriminatory Access

These should not be treated as identical.

Refusal to deal

The infrastructure owner says:

“You cannot use the facility.”

The legal question focuses heavily on indispensability and alternatives.

Discriminatory access

The infrastructure owner says:

“You can use it, but only under worse conditions than another comparable user.”

The analysis can focus more strongly on:

• discrimination,
• foreclosure,
• unequal treatment,
• pricing,
• technical conditions,
• competitive effects.

This distinction is particularly important in regulated infrastructure sectors.

25. Practical Competition-Law Test

A useful analytical framework is:

Step 1 — Define the market

Identify:

• infrastructure market,
• upstream market,
• downstream market,
• geographic market.

Step 2 — Establish control

Determine who controls the infrastructure.

Step 3 — Assess dominance

Examine market power and barriers to entry.

Step 4 — Determine necessity

Ask whether competitors genuinely need the facility.

Step 5 — Examine alternatives

Can competitors reasonably:

• build another facility?
• use another network?
• substitute another technology?
• access another geographic facility?

Step 6 — Examine conduct

Was there:

• complete refusal?
• delay?
• discriminatory access?
• excessive price?
• technical restriction?
• capacity allocation discrimination?
• infrastructure removal?

Step 7 — Assess competitive effects

Consider whether the conduct:

• excludes competitors,
• raises entry barriers,
• protects a downstream affiliate,
• reduces consumer choice,
• increases prices,
• reduces innovation.

Step 8 — Examine justification

Consider:

• safety,
• capacity,
• technical feasibility,
• security,
• regulation,
• investment incentives.

Step 9 — Consider remedy

Possible remedies include:

• access,
• non-discrimination,
• interoperability,
• pricing controls,
• transparency,
• behavioural commitments,
• penalties.

26. Major Cases at a Glance

27. Conclusion

Competition law does not generally impose an automatic duty on every infrastructure owner to share its facilities with competitors.

The strongest access cases normally involve a combination of:

• significant market power,
• control over an important facility,
• genuine indispensability,
• lack of realistic alternatives,
• substantial competitive harm,
• exclusionary conduct, and
• absence of adequate objective justification.

The Bronner, Commercial Solvents, IMS Health, Deutsche Telekom, Slovak Telekom and Lietuvos geležinkeliai decisions are particularly useful for understanding how European competition law approaches access to infrastructure and related refusal-to-deal, discriminatory-access and margin-squeeze problems.
