Internal Guidelines vs Binding Legal Standards in Competition Authorities

1. Introduction

Competition authorities routinely use internal guidelines, notices, manuals, enforcement priorities, policy papers, decisional practice and administrative guidance to structure the exercise of their statutory powers. These instruments are important because competition law frequently involves complex economic assessments, particularly in cases involving dominance, mergers, commitments, penalties, market definition and remedies.

However, an important constitutional and administrative-law distinction exists between:

binding legal standards, which derive from legislation, regulations, treaties or authoritative judicial interpretation; and

internal guidelines, which ordinarily guide the authority's own decision-making but do not themselves possess the force of legislation.

The distinction becomes particularly significant where an authority relies upon an internal document to impose a burden, penalty, restriction or obligation that cannot clearly be derived from the governing statute.

The fundamental principle is:

An administrative authority cannot ordinarily convert its internal policy into binding law merely by treating the policy as mandatory.

At the same time, an authority may legitimately adopt guidelines to promote consistency, transparency and predictability, provided that the guidelines remain within the limits of the statutory framework.

2. Meaning of Internal Guidelines

Internal guidelines are administrative instruments designed to assist an authority in exercising its statutory functions.

They may include:

enforcement manuals;

merger guidelines;

penalty-calculation policies;

prioritisation criteria;

internal procedural instructions;

compliance guidance;

interpretive notices;

staff manuals;

decisional frameworks;

commitment guidelines;

leniency policies.

Their principal purposes are:

consistency;

administrative efficiency;

transparency;

predictability;

institutional coordination;

prioritisation of enforcement resources.

They are particularly useful in technically complex areas of competition law.

3. What Is a Binding Legal Standard?

A binding legal standard derives from a legally recognised source.

Depending upon the jurisdiction, it may arise from:

constitutional provisions;

legislation;

delegated legislation;

regulations;

binding international obligations;

authoritative judicial decisions.

For example, a competition authority may have statutory authority to determine whether conduct constitutes abuse of dominance.

Its internal guidance may explain how it intends to assess dominance, but the authority remains legally bound by:

the statutory definition;

procedural requirements;

applicable evidentiary standards;

judicial interpretation;

principles of natural justice;

proportionality and reasonableness where applicable.

4. The Central Distinction

The distinction is not merely theoretical.

It determines whether an affected undertaking can argue:

“The authority has departed from its own policy”

or the stronger argument:

“The authority has acted contrary to binding law.”

5. Why the Distinction Matters in Competition Law

Competition authorities possess substantial discretionary powers.

They may decide:

which investigations to initiate;

how to define relevant markets;

how to evaluate market power;

whether conduct is exclusionary;

how to calculate penalties;

whether remedies are appropriate;

whether a merger raises competition concerns.

Because of this discretion, internal guidelines can become highly influential.

The danger arises when a guideline becomes de facto legislation.

For example, suppose an authority's internal policy states that a particular category of conduct will automatically result in a particular penalty.

If the statute provides discretion requiring an individualised assessment, the authority cannot necessarily transform its internal policy into an inflexible rule.

6. Administrative Guidelines and Legitimate Expectations

Internal guidelines may nevertheless have legal significance.

Where an authority consistently represents that it will follow a particular policy, businesses may develop expectations concerning administrative treatment.

This connects the issue with:

legitimate expectations;

consistency;

equality;

non-arbitrariness;

procedural fairness.

However, legitimate expectation does not ordinarily permit an authority to continue an unlawful policy.

Thus:

An authority may be expected to administer its lawful policy consistently, but an unlawful policy cannot become law merely through consistent application.

7. Case Law

1. Joined Cases C-189/02 P etc., Dansk Rørindustri v Commission (2005)

The Court of Justice of the European Union examined the legal significance of the European Commission's guidelines concerning fines.

The Court recognised that guidelines could contribute to transparency and predictability in the exercise of the Commission's discretion.

At the same time, the Commission could not treat its guidelines as eliminating the discretion granted by the Treaty and applicable legislation.

Principle

Guidelines may structure administrative discretion, but they do not replace the underlying legal framework.

Competition-law significance

This is one of the clearest authorities for understanding the distinction between self-imposed administrative guidance and binding legal rules.

8. 2. Case C-226/11, Expedia Inc. v Autorité de la concurrence (2012)

The Expedia judgment concerned EU competition law and the relationship between national competition enforcement and the requirements of EU competition law.

The Court emphasised the importance of the binding legal framework created by Articles 101 and 102 TFEU and the applicable EU regulations.

Principle

Administrative enforcement policies cannot displace the substantive requirements of EU competition law.

Significance

An authority's internal approach must remain subordinate to the legally binding competition rules.

9. 3. Case C-413/14 P, Intel Corp. v Commission (2017)

The Intel litigation is particularly important because it demonstrates that competition authorities must properly apply the legally relevant analytical framework.

The Commission's enforcement approach concerning rebates was scrutinised by the EU courts.

The Court required appropriate consideration of the circumstances relevant to whether conduct was capable of producing exclusionary effects.

Principle

An authority cannot rely upon a simplified enforcement approach where the governing legal standard requires a more substantive assessment.

Relevance

Internal enforcement priorities cannot replace the legally applicable test for abuse of dominance.

10. 4. Case C-23/14, Post Danmark A/S v Konkurrencerådet (2015)

Post Danmark concerned exclusionary conduct and Article 102 TFEU.

The Court emphasised the legal framework governing abuse of dominance and the assessment of whether conduct is capable of restricting competition.

Principle

Competition authorities must apply the legally established substantive test rather than treating administrative policy as an independent source of liability.

Relevance

Internal guidance can help structure economic analysis, but it cannot substitute for the legal test established by EU competition law.

11. 5. Case C-280/08 P, Deutsche Telekom AG v Commission (2010)

Deutsche Telekom involved an Article 102 TFEU abuse-of-dominance case concerning margin squeeze.

The Court confirmed the importance of applying the legal principles governing exclusionary conduct.

Principle

The Commission's enforcement discretion operates within the legal boundaries of Article 102 TFEU.

Relevance

An authority cannot create liability simply because conduct conflicts with an internal enforcement preference. The conduct must satisfy the applicable legal standard.

12. 6. Case C-52/09, TeliaSonera Sverige AB v Konkurrensverket (2011)

TeliaSonera dealt with margin squeeze and the application of Article 102 TFEU.

The Court clarified the substantive conditions relevant to assessing exclusionary pricing conduct.

Principle

Competition enforcement must be anchored in the legally applicable doctrine, including the requirements developed through judicial interpretation.

Significance

Guidelines can assist economic analysis but cannot independently create a new category of prohibited conduct.

13. 7. Case C-7/97, Oscar Bronner GmbH & Co. KG v Mediaprint (1998)

Oscar Bronner established important principles concerning refusal to supply and access to essential facilities.

The Court adopted a demanding legal framework for imposing access obligations upon a dominant undertaking.

Relevance

An authority cannot simply announce through internal guidance that a dominant firm must provide access to an infrastructure.

The legal requirements for intervention must be satisfied.

Principle

Administrative convenience cannot replace the substantive legal threshold established by competition law.

14. 8. Case C-209/10, Post Danmark A/S v Konkurrencerådet (2012)

This judgment further illustrates the importance of applying the legally established framework for exclusionary conduct.

The Court assessed whether pricing practices by a dominant undertaking were capable of restricting competition.

Significance

Competition authorities must distinguish between:

internal enforcement priorities;

economic presumptions;

legally established presumptions; and

the actual statutory/Treaty test.

That distinction is essential when enforcement guidelines purport to simplify complex economic analysis.

15. Internal Guidelines Are Not Necessarily Legally Irrelevant

It would be incorrect to conclude that guidelines have no legal importance.

They may perform at least five important functions.

A. Self-binding

An authority may voluntarily commit itself to following a particular methodology.

B. Transparency

Businesses can better predict enforcement decisions.

C. Consistency

Similar cases can be treated similarly.

D. Legitimate expectation

Under appropriate circumstances, departures may require justification.

E. Judicial review

A court may examine whether an authority irrationally or inconsistently departed from its published policy.

Thus, guidelines occupy an intermediate position:

They may constrain administrative discretion without becoming legislation.

16. Self-Imposed Administrative Constraints

Competition authorities sometimes deliberately restrict their own discretion.

For example, an authority might announce:

"We will normally treat conduct satisfying X conditions as high priority."

This does not necessarily mean:

"The law requires enforcement whenever X occurs."

The distinction between normally and mandatorily is legally important.

An authority can ordinarily retain the ability to depart from its policy where:

the facts are exceptional;

enforcement priorities have changed;

the policy conflicts with a superior legal requirement;

new judicial authority has emerged;

the policy itself requires revision.

But unexplained departures can raise concerns about arbitrariness or unequal treatment.

17. Guidelines and Penalty Calculation

Penalty guidelines provide a particularly important example.

Suppose legislation authorises a competition authority to impose a penalty up to a specified maximum.

The authority then adopts internal guidelines establishing:

starting percentages;

aggravating factors;

mitigating factors;

duration multipliers;

cooperation reductions.

The guideline can increase predictability.

However, the authority generally cannot treat the guideline as eliminating statutory discretion where the legislature intended an individualised assessment.

The final penalty must remain legally connected to:

the statute;

the facts;

proportionality;

procedural fairness;

applicable judicial review.

18. Merger Guidelines

Merger guidelines illustrate the issue particularly well.

An authority may establish thresholds for:

market concentration;

HHI;

market shares;

vertical concerns;

potential competition;

efficiencies.

These thresholds are usually screening tools, not automatically binding rules of illegality.

For example:

HHI increase above X → detailed investigation.

This does not necessarily mean:

HHI increase above X → merger automatically unlawful.

The latter would require appropriate legal authority.

19. Soft Law and Competition Authorities

Internal guidelines are often described as soft law.

Soft law occupies a space between:

purely informal administrative practice; and

formally binding legislation.

Competition authorities frequently rely upon soft law because competition economics changes rapidly.

It permits authorities to adapt their analytical methodology without repeatedly seeking legislative amendment.

However:

Flexibility must not become a mechanism for bypassing legislative safeguards.

20. Judicial Review of Internal Guidelines

Courts may scrutinise internal guidelines in several ways.

1. Ultra vires review

Did the authority exceed its statutory powers?

2. Illegality

Did the authority apply an unlawful rule?

3. Irrationality/unreasonableness

Was the policy or its application irrational?

4. Procedural fairness

Was the affected undertaking given a fair opportunity to respond?

5. Proportionality

Was the enforcement measure proportionate?

6. Equality/consistency

Were similar undertakings treated differently without justification?

21. Internal Guidelines Cannot Override Statutes

This is the most important hierarchy.

The hierarchy can generally be expressed as:

Constitution / Treaty

↓

Primary legislation

↓

Lawfully adopted regulations

↓

Binding judicial interpretation

↓

Administrative guidelines

↓

Internal manuals/prioritisation policies

An internal guideline cannot normally override a higher-level legal rule.

Where a conflict exists, the authority must follow the higher legal norm.

22. Guidelines and the Principle of Legality

The principle of legality requires public authorities to exercise coercive powers according to law.

This becomes especially important in competition law because authorities can impose:

substantial fines;

behavioural restrictions;

structural remedies;

merger prohibitions;

divestiture obligations.

The greater the impact on legal rights, the stronger the justification for identifying a clear legal foundation.

An internal document cannot itself provide the legal authority necessary to impose a coercive measure unless legislation expressly delegates such rule-making power.

23. Binding Legal Standards and Judicial Precedent

Judicial decisions occupy a different position from internal guidance.

Where a higher court authoritatively interprets a competition-law provision, the authority generally cannot simply disregard that interpretation because its internal manual adopts a different approach.

For example:

Internal guideline → economic screening methodology.

versus:

Binding judicial precedent → legal test for abuse of dominance.

The second has legal priority.

24. The Problem of De Facto Binding Guidelines

One of the most difficult situations occurs when an authority formally describes a document as "non-binding" but applies it rigidly.

Suppose the authority states:

"The guidelines are merely indicative."

But every investigation follows them mechanically, without considering individual circumstances.

The court may then examine whether the authority has effectively transformed the policy into a binding rule.

This creates a distinction between:

De jure non-binding

The document is formally advisory.

De facto binding

The authority treats the document as mandatory in practice.

The latter can create serious administrative-law concerns.

25. Guidelines and Legitimate Expectations

Businesses may rely upon published competition guidelines when making:

investment decisions;

merger plans;

compliance programmes;

licensing decisions;

pricing decisions;

commercial arrangements.

If an authority unexpectedly departs from a published policy, affected parties may argue that the departure undermines legitimate expectations.

However, the strength of that argument depends upon:

the wording of the guideline;

whether representations were specific;

whether reliance was reasonable;

whether the authority had reserved discretion;

whether public interest requires departure.

26. Internal Guidelines and Equal Treatment

Consistency is another important consideration.

Two businesses engaging in materially similar conduct should not ordinarily receive radically different treatment simply because one happens to be investigated under a different internal approach.

Nevertheless, consistency does not mean that an unlawful earlier decision must automatically be repeated.

The authority may correct its previous error while explaining the change.

Thus:

Consistency is important, but legality remains paramount.

27. Competition Authority Discretion

Competition authorities necessarily possess discretion because markets are economically complex.

They must often determine:

relevant market boundaries;

competitive constraints;

counterfactual scenarios;

effects on innovation;

foreclosure risks;

efficiencies;

consumer harm.

Internal guidelines provide a methodology for exercising this discretion.

The legally appropriate approach is therefore not:

"Guidelines are irrelevant."

Nor is it:

"Guidelines are law."

Rather:

Guidelines structure lawful discretion but cannot normally enlarge the authority's statutory jurisdiction.

28. Practical Test for Courts and Lawyers

When challenging reliance on an internal guideline, several questions should be asked:

Question 1

What is the statutory source of the authority's power?

Question 2

Does the statute authorise the particular restriction?

Question 3

Is the guideline merely interpretive or does it create substantive obligations?

Question 4

Does the guideline contradict legislation or judicial precedent?

Question 5

Did the authority retain discretion?

Question 6

Did it consider the individual facts?

Question 7

Did it explain any departure from its published policy?

Question 8

Was the undertaking given procedural fairness?

Question 9

Is the resulting decision proportionate?

Question 10

Has the authority effectively converted a policy into a mandatory rule without legislative authority?

29. Application to Digital Competition

The issue becomes particularly important in emerging digital competition regulation.

Competition authorities may develop guidelines dealing with:

algorithmic pricing;

AI coordination;

data concentration;

platform self-preferencing;

interoperability;

ecosystem foreclosure;

digital mergers;

killer acquisitions.

Because technology develops rapidly, authorities need flexibility.

But digital-market guidelines should still distinguish between:

economic indicators

and

legal elements of liability.

For example:

"High data concentration indicates increased competitive risk"

is an economic proposition.

It is different from:

"Any undertaking possessing this level of data is legally dominant."

The second proposition requires a proper legal basis.

30. Internal Guidelines vs Binding Legal Standards — Comparative Summary

31. Overall Legal Position

The relationship between internal guidelines and binding legal standards can therefore be summarised through four propositions:

Proposition 1 — Guidelines are subordinate to law

An authority cannot use internal guidance to override legislation or binding judicial interpretation.

Proposition 2 — Guidelines may legitimately structure discretion

An authority can develop methodologies that promote consistency and predictability.

Proposition 3 — Departure may require justification

Where an authority has publicly adopted a policy, unexplained departures can raise concerns involving fairness, equality and legitimate expectations.

Proposition 4 — Guidelines cannot ordinarily create new substantive liability

An authority cannot manufacture a new prohibition, offence or coercive power merely by putting it into an internal manual.

32. Conclusion

The distinction between internal guidelines and binding legal standards is fundamental to legitimate competition enforcement.

Competition authorities need guidelines because modern competition cases involve highly technical questions of economics, technology, data, market definition and innovation. Guidelines can make enforcement more predictable and reduce arbitrary decision-making.

Nevertheless, they remain subordinate to the governing legal framework.

The principal rule is:

A competition authority may guide the exercise of a power granted by law, but it cannot obtain a power merely by issuing guidance.

The case law, particularly Dansk Rørindustri, Intel, Post Danmark, Deutsche Telekom, TeliaSonera and Oscar Bronner, demonstrates the importance of keeping administrative methodology within the boundaries of substantive competition law.

Accordingly, the proper relationship is not one of competition between guidelines and law, but one of hierarchy:

Binding legal standards establish what the authority may lawfully do; internal guidelines explain how the authority intends to exercise that lawful power.

When that boundary is respected, guidelines enhance transparency and consistency. When the boundary is crossed, internal guidance risks becoming unauthorised de facto legislation, creating grounds for judicial review.
