ICN (International Competition Network) Soft-Law Influence on Digital Markets

1. Introduction

The International Competition Network (ICN) is a global network of competition authorities rather than a treaty-based international regulator. It promotes convergence through recommended practices, reports, workshops, investigative guidance, agency cooperation, and peer learning.

Its importance in digital markets arises because digital competition problems—such as platform self-preferencing, data advantages, algorithmic pricing, interoperability restrictions, digital mergers, exclusionary conduct, and ecosystem leverage—frequently cross national borders.

The ICN's instruments generally do not create directly binding legal obligations for businesses or national competition authorities. Nevertheless, they can exercise substantial soft-law influence by shaping:

• how competition authorities define markets;
• how agencies identify theories of harm;
• merger-investigation techniques;
• treatment of digital evidence and economic data;
• assessment of dominance and exclusion;
• approaches to remedies;
• cooperation between regulators;
• convergence of national enforcement practices.

Thus, the ICN can influence digital competition law without formally legislating it.

2. Meaning of ICN Soft Law

Soft law refers to norms, principles, recommendations, guidelines, reports, best practices, and institutional practices that are not formally binding in the same way as legislation or judicial decisions, but nevertheless influence governmental and regulatory behaviour.

The ICN operates particularly through:

1. Recommended Practices
2. Reports and working-group documents
3. Investigative and enforcement guidance
4. Agency-to-agency cooperation
5. Peer review and benchmarking
6. Annual conferences and workshops
7. Common terminology and analytical frameworks

The influence mechanism can be represented as:

ICN Recommendation → National Competition Authority → Domestic Guidance/Enforcement Practice → Courts → Market Participants

The ICN therefore contributes to a form of transnational regulatory convergence.

3. Why ICN Soft Law Matters Particularly in Digital Markets

Digital markets present several characteristics that make international convergence important.

A. Global platforms

A single platform may operate simultaneously in:

• India;
• the EU;
• the United States;
• the United Kingdom;
• Australia;
• Japan;
• Brazil; and
• numerous other jurisdictions.

Different approaches to the same conduct can produce regulatory conflict.

B. Rapid technological change

Traditional legislation can become outdated quickly.

ICN reports and recommended practices can be modified more rapidly than formal legislation.

C. Digital mergers

Acquisitions involving:

• start-ups;
• data;
• algorithms;
• cloud infrastructure;
• AI systems;
• APIs; and
• emerging competitors

may create competitive concerns before conventional market shares become large.

D. Non-price competition

Digital competition frequently involves:

• privacy;
• quality;
• innovation;
• interoperability;
• data access;
• ecosystem participation; and
• user attention.

The ICN's analytical convergence can help authorities assess these dimensions.

4. Principal Areas of ICN Soft-Law Influence

A. Market Definition

Traditional competition analysis often focuses on price.

Digital markets require greater attention to:

• zero-price services;
• multi-sided platforms;
• indirect network effects;
• switching costs;
• data;
• interoperability;
• multi-homing;
• attention;
• ecosystem relationships.

ICN work encourages competition authorities to develop methodologies capable of addressing these characteristics.

B. Dominance and Market Power

Digital market power may arise from more than market share.

Authorities may consider:

• network effects;
• data accumulation;
• economies of scale and scope;
• switching costs;
• ecosystem integration;
• interoperability advantages;
• default positions;
• control over technical standards;
• access to essential digital infrastructure.

This contributes to a broader understanding of market power.

5. ICN Influence on Digital Merger Control

One of the most significant areas is merger review.

Digital acquisitions can involve a small target but a potentially important competitive threat.

Examples include:

• acquisition of a nascent competitor;
• acquisition of an important dataset;
• acquisition of an AI developer;
• acquisition of an interoperability technology;
• acquisition of an emerging platform.

ICN merger-control principles can influence national authorities in considering:

Horizontal effects

Whether the transaction removes an actual or potential competitor.

Vertical effects

Whether a platform can disadvantage downstream competitors.

Conglomerate effects

Whether complementary digital products can be tied or bundled.

Innovation effects

Whether acquisition reduces future innovation.

Data effects

Whether combining datasets creates a competitive advantage unavailable to rivals.

6. ICN Influence on Digital Abuse-of-Dominance Cases

ICN soft law can affect the conceptual framework used to examine:

• self-preferencing;
• tying;
• refusal to deal;
• discriminatory access;
• exclusive dealing;
• interoperability restrictions;
• predatory pricing;
• loyalty-inducing practices;
• exploitative data practices.

The ICN does not itself establish that a particular digital practice is unlawful. Instead, its analytical work can influence how agencies formulate the relevant theory of harm.

7. ICN and Algorithmic Competition

Algorithms create distinctive enforcement questions.

For example, algorithms may:

• independently adjust prices;
• respond to competitors' prices;
• coordinate supply;
• discriminate between customers;
• determine search rankings;
• allocate advertising opportunities.

ICN soft-law thinking encourages agencies to examine whether apparently automated conduct produces:

coordination → reduced rivalry → higher prices or reduced quality/innovation

The important legal question remains whether existing competition-law doctrines can be applied to technologically mediated behaviour.

8. ICN and Digital Evidence

Digital investigations generate enormous quantities of evidence:

• source code;
• transaction data;
• communications;
• algorithmic logs;
• internal strategy documents;
• API records;
• database structures;
• platform metrics.

ICN cooperation can promote convergence regarding:

• evidence gathering;
• economic analysis;
• investigative techniques;
• confidentiality;
• cross-border cooperation.

This is particularly important because evidence concerning a digital platform may be distributed across several jurisdictions.

9. ICN and Remedies

Digital markets create difficult remedial questions.

Traditional remedies may be insufficient where the competitive problem results from:

• network effects;
• data concentration;
• interoperability barriers;
• ecosystem dependency;
• algorithmic ranking;
• default settings.

Potential remedies include:

• behavioural restrictions;
• interoperability obligations;
• data-access remedies;
• non-discrimination obligations;
• structural remedies;
• divestiture;
• monitoring;
• compliance obligations.

ICN soft law can provide comparative experience concerning which remedies are administratively workable.

10. ICN and Convergence Between Competition Authorities

The ICN's most important soft-law function may be institutional convergence.

A competition authority can learn from another authority's experience without being legally compelled to follow it.

This produces:

persuasive convergence rather than formal legal harmonisation.

For digital markets, this can reduce inconsistent approaches to the same multinational platform.

11. At Least 6 Important Case Laws

The ICN itself does not normally issue binding judgments. Therefore, the following cases are important because they illustrate the substantive digital competition issues around which international competition-law thinking has converged, rather than because the courts treated ICN documents as binding law.

Case 1: Google Search (Shopping) – European Commission / General Court

Facts

Google was accused of favouring its own comparison-shopping service in search results while disadvantaging competing comparison-shopping services.

Legal issue

The central issue concerned whether Google's conduct constituted an abuse of dominance under Article 102 TFEU.

Significance

The case demonstrated that digital competition can involve:

• ranking algorithms;
• search neutrality;
• self-preferencing;
• platform control;
• visibility;
• access to users.

Relevance to ICN soft law

The case illustrates why international competition authorities need shared analytical frameworks for digital platforms.

It also demonstrates the limits of traditional market-share analysis when competition occurs through algorithmic access and platform architecture.

Case 2: Google Android – European Commission

Facts

The European Commission examined Google's contractual practices concerning Android devices, including:

• pre-installation;
• search defaults;
• app stores;
• restrictions involving competing mobile operating systems.

Legal issue

The Commission examined whether Google's practices reinforced its dominant position in search and restricted competition.

Significance

The case illustrates:

• ecosystem power;
• tying;
• defaults;
• network effects;
• platform leverage.

ICN connection

These issues are relevant to the international convergence promoted by the ICN because digital ecosystems frequently combine several interconnected markets.

Case 3: Microsoft Corp. v. Commission

Facts

Microsoft was found to have abused its dominant position through conduct involving interoperability and the integration of products within its software ecosystem.

Legal issue

The case addressed exclusionary conduct and interoperability.

Significance

It established important principles concerning:

• interoperability;
• technological ecosystems;
• refusal to supply;
• product integration;
• leveraging.

ICN connection

The reasoning has wider relevance to digital-platform competition because interoperability has become a central issue in modern platform regulation.

The case demonstrates how competition authorities can develop principles that later become part of broader international regulatory thinking.

Case 4: United States v. Microsoft Corp.

Facts

The United States challenged Microsoft's conduct concerning its operating-system monopoly and the competitive position of web browsers.

Legal issue

The litigation concerned exclusionary conduct and maintenance of monopoly power.

Significance

The case became one of the foundational precedents for understanding:

• software-platform power;
• network effects;
• technological tying;
• exclusionary contracts;
• innovation competition.

ICN relevance

The case illustrates why international networks of competition authorities are valuable: digital-platform markets often present substantially similar economic problems across jurisdictions.

The Microsoft litigation also influenced later thinking about platform markets internationally.

Case 5: FTC v. Facebook / Meta

Facts

The United States Federal Trade Commission challenged Facebook's conduct involving acquisitions and alleged maintenance of monopoly power in personal social networking.

Legal issues

The case concerns:

• platform market power;
• acquisitions of potential competitors;
• network effects;
• data;
• switching costs;
• exclusionary strategies.

Significance

It illustrates the importance of analysing digital mergers not merely through contemporary market share but also through:

future competition + network effects + data + potential entrants.

ICN connection

This is closely connected with the international debate concerning digital merger control and acquisitions of nascent competitors.

ICN merger-policy discussions can therefore contribute to a common analytical vocabulary even where domestic legal tests differ.

Case 6: Bundeskartellamt v. Meta Platforms / Facebook

Facts

The German competition authority examined Facebook's combination of user data obtained from Facebook and other services.

Legal issue

The case concerned the relationship between:

• data collection;
• privacy;
• exploitative conduct;
• dominance;
• competition law.

Significance

The case demonstrated that data practices can become relevant to competition-law analysis.

It also highlighted the increasingly important relationship between competition law and data governance.

ICN relevance

Digital competition frequently involves issues that cross traditional regulatory boundaries.

The ICN's comparative approach can assist authorities in understanding how other jurisdictions approach data-driven market power.

Case 7: Apple App Store – European Commission

Facts

Apple's App Store practices concerning developers and payment arrangements have been examined under European competition law.

Issues

The principal concerns include:

• platform gatekeeping;
• commission structures;
• access conditions;
• self-preferencing;
• app distribution;
• payment restrictions.

Significance

The case illustrates the transformation of digital platforms into gatekeepers controlling access to downstream markets.

ICN relevance

This is precisely the type of problem where competition authorities benefit from shared international analytical approaches.

Case 8: Amazon Marketplace – European Commission

Facts

The European Commission examined Amazon's use of non-public marketplace seller data and the potential competitive implications of Amazon simultaneously operating a marketplace and competing with marketplace sellers.

Legal significance

The case raised concerns involving:

• vertically integrated platforms;
• data advantages;
• conflicts of interest;
• platform neutrality;
• self-preferencing.

ICN connection

This is highly relevant to international soft-law development because the platform-as-marketplace-and-competitor problem appears across many digital economies.

12. How ICN Soft Law Produces Legal Influence

The influence mechanism can be expressed as follows:

Stage 1 — International discussion

Competition authorities discuss a new digital competition problem within the ICN.

↓

Stage 2 — Analytical convergence

Authorities develop common terminology and analytical approaches.

↓

Stage 3 — Domestic incorporation

A national authority incorporates those concepts into:

• guidelines;
• enforcement priorities;
• merger analysis;
• investigative practice.

↓

Stage 4 — Enforcement

The authority applies the approach to a specific platform or digital transaction.

↓

Stage 5 — Judicial review

Domestic courts examine the legality of the authority's action.

↓

Stage 6 — Further international convergence

The resulting experience becomes part of international competition-law discussion.

Thus:

ICN → Agencies → Domestic Law → Courts → International Learning

13. ICN Soft Law Versus Hard Law

14. Advantages of ICN Soft Law in Digital Markets

A. Speed

Digital markets develop faster than legislation.

Soft-law instruments can respond more quickly.

B. Expertise

Competition authorities can exchange technical knowledge concerning:

• algorithms;
• AI;
• platforms;
• data;
• cloud computing;
• digital mergers.

C. Regulatory convergence

It reduces unnecessary divergence between national authorities.

D. Lower institutional costs

Authorities can learn from previous investigations rather than developing every methodology independently.

E. Cross-border enforcement

Cooperation becomes particularly valuable where evidence, firms, and economic effects span multiple jurisdictions.

15. Limitations of ICN Soft Law

1. No direct binding force

An ICN recommendation cannot normally substitute for domestic legislation.

2. Democratic legitimacy concerns

Competition authorities participating in international networks are not equivalent to an international legislature.

3. Different legal systems

The same economic conduct may be treated differently under:

• EU competition law;
• US antitrust law;
• Indian competition law;
• UK competition law;
• Japanese competition law.

4. Judicial independence

Domestic courts are not automatically bound by ICN recommendations.

5. Risk of informal harmonisation

Soft-law convergence can sometimes create substantial practical pressure toward a common regulatory approach without the formal safeguards associated with treaty-making or legislation.

16. ICN and Developing Digital Economies

ICN soft law can be particularly significant for developing jurisdictions.

A newer competition authority may lack extensive experience with:

• digital merger review;
• algorithmic markets;
• platform economics;
• cloud markets;
• data-driven dominance.

ICN materials provide a form of institutional capacity building.

However, national authorities must adapt international approaches to their own:

• market structure;
• economic conditions;
• statutory framework;
• constitutional principles;
• consumer characteristics.

17. ICN Influence in India

For India, ICN soft-law influence is particularly relevant to the Competition Commission of India (CCI).

The CCI can benefit from international competition-authority experience when analysing:

• digital platforms;
• app stores;
• online marketplaces;
• search engines;
• digital advertising;
• data-driven market power;
• algorithmic pricing;
• digital mergers.

The important distinction is that an ICN recommendation does not automatically become Indian law.

Indian legal authority continues to come principally from:

• the Competition Act, 2002;
• regulations;
• CCI decisions;
• appellate decisions;
• Supreme Court jurisprudence.

ICN principles may instead operate as persuasive comparative material and institutional guidance.

18. Soft Law and the Digital Competition Act/Ex-Ante Regulation Debate

Digital markets increasingly raise the question whether conventional ex-post competition law is sufficient.

The debate concerns whether certain platforms require:

• ex-ante obligations;
• interoperability requirements;
• data-access requirements;
• restrictions on self-preferencing;
• merger controls;
• transparency obligations.

ICN soft law can contribute analytical material to this debate without itself creating ex-ante obligations.

This distinction is crucial:

ICN can influence the development of regulatory thinking, but it does not itself legislate digital markets.

19. ICN as a Transnational Governance Mechanism

The deeper significance of the ICN is institutional.

It represents a form of networked governance, where competition authorities cooperate horizontally rather than through a hierarchical international regulator.

The structure can be conceptualised as:

National Authorities
↓
International Network
↓
Shared Principles
↓
Regulatory Convergence
↓
Comparable Enforcement Methodologies

This is particularly suitable for digital markets because platforms operate internationally while competition authorities remain predominantly national or regional.

20. Key Legal Principles Emerging From ICN-Influenced Digital Competition Analysis

Several recurring principles are particularly important:

1. Market power must be analysed dynamically.
2. Network effects can strengthen durable dominance.
3. Data can constitute an important competitive asset.
4. Innovation may be a significant dimension of competition.
5. Digital mergers may eliminate potential competition.
6. Interoperability can affect competitive access.
7. Platform architecture can influence competitive conditions.
8. Multi-sided market effects should be considered.
9. Remedies must account for technological realities.
10. International cooperation is increasingly necessary.

21. Critical Assessment

The ICN's greatest influence is not its ability to impose rules. It is its ability to shape the assumptions, vocabulary, investigative techniques and institutional expectations of competition authorities.

In digital markets, this can be especially powerful because agencies repeatedly encounter similar problems involving:

• Google;
• Apple;
• Meta;
• Amazon;
• Microsoft;
• large app stores;
• online marketplaces;
• cloud providers;
• AI platforms.

The result is a form of soft harmonisation.

However, convergence should not be confused with uniformity. Domestic legislation and judicial interpretation remain decisive.

22. Conclusion

The International Competition Network's soft-law influence on digital markets operates primarily through regulatory convergence rather than legally binding commands.

Its recommended practices, reports, workshops and cooperation mechanisms can influence how competition authorities understand:

• digital market definition;
• dominance;
• data-driven market power;
• platform ecosystems;
• self-preferencing;
• interoperability;
• digital mergers;
• algorithmic conduct;
• remedies; and
• cross-border enforcement.

The cases involving Google, Microsoft, Meta/Facebook, Apple and Amazon demonstrate the substantive problems that make international convergence important.

The central legal proposition is therefore:

ICN soft law does not replace national competition law; it influences the interpretation, enforcement methodology and institutional development through which national competition law is applied to rapidly evolving digital markets.

Its significance is consequently best understood as transnational regulatory influence without formal legislative authority.
