Indirect Purchaser Standing in Germany

1. Introduction

Indirect purchaser standing concerns whether a person or undertaking that did not buy directly from the cartel participant, but purchased the affected product further down the distribution chain, can claim damages for an infringement of competition law.

In Germany, the issue is particularly important in cartel damages litigation under § 33a of the German Competition Act (GWB), read together with the general damages provisions of the GWB and the principles derived from EU competition law.

The central difficulty is causal: an indirect purchaser must generally establish that the competition-law infringement caused an overcharge or other compensable loss that was transmitted through one or more levels of the supply chain.

German law does not simply exclude indirect purchasers because there was no direct contractual relationship with the cartel member. Instead, the legal framework asks whether the claimant falls within the protected class and can establish the necessary causal connection and damage.

2. Meaning of an Indirect Purchaser

An indirect purchaser is a person who purchases a cartelised product from an intermediary rather than directly from the infringing undertaking.

Example

Assume:

Manufacturer → Distributor → Wholesaler → Retailer → Consumer

If the manufacturer fixes the price of the product, the manufacturer may sell to the distributor at an inflated price.

The distributor may pass some or all of that overcharge to the wholesaler, which may pass it to the retailer and ultimately the consumer.

The final consumer is therefore an indirect purchaser.

The legal question is:

Can the final consumer claim damages from the cartel participant even though the consumer never purchased directly from that cartel participant?

In Germany, the answer can be yes, provided the statutory requirements for a competition-law damages claim are satisfied.

3. Statutory Framework in Germany

A. § 33 GWB

§ 33 GWB establishes the basic private-enforcement framework for competition-law infringements.

A person harmed by an infringement may seek appropriate remedies where the statutory requirements are satisfied.

The provision is important because competition law is not confined to public enforcement by the Bundeskartellamt.

Private parties can also pursue compensation.

4. § 33a GWB and Cartel Damages

The central provision for cartel damages is § 33a GWB.

It establishes the right to compensation for damage caused by a competition-law infringement.

The provision must be understood alongside the EU Cartel Damages Directive (Directive 2014/104/EU), which significantly harmonised private enforcement throughout the EU.

The German implementation strengthened the position of persons harmed at different levels of the supply chain.

5. Why Indirect Purchaser Claims Are Difficult

The basic economic chain is:

Cartel → direct purchaser → intermediary → indirect purchaser

The claimant has to establish several issues.

1. Existence of infringement

There must be an infringement of competition law.

Examples include:

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

2. Standing or entitlement to claim

The claimant must fall within the legally protected category of persons suffering compensable harm.

3. Causation

The claimant must establish that the infringement contributed to the loss.

4. Overcharge transmission

Where the claimant purchased further down the distribution chain, the claimant must demonstrate that the cartel overcharge was transmitted to its level.

5. Quantum

The court must determine the amount of damage.

This often requires economic evidence.

6. Passing-On and Indirect Purchasers

The passing-on problem operates in two directions.

Direct purchaser

Suppose:

• cartel price = €100;
• competitive price = €80;
• overcharge = €20.

The direct purchaser pays €20 too much.

But suppose the direct purchaser increases its resale price by €15.

Its ultimate loss may therefore be only €5.

Indirect purchaser

The indirect purchaser may ultimately bear some or all of the €20 overcharge.

This produces the classic tension:

Who actually suffered the economic loss?

German and EU competition law attempts to prevent both:

• under-compensation, where the actual loss is not recovered; and
• over-compensation, where multiple purchasers recover the same loss.

7. The Cartel Damages Directive

Directive 2014/104/EU is fundamental to understanding modern German law.

It recognises that persons at different stages of a distribution chain may suffer harm from a cartel.

The Directive contains provisions dealing with:

• passing-on;
• indirect purchasers;
• disclosure of evidence;
• limitation periods;
• quantification of harm;
• rebuttable presumptions;
• joint and several liability.

Germany incorporated these principles into the GWB.

8. Presumption of Damage from Cartels

German cartel damages law contains an important evidentiary mechanism.

Certain cartel infringements generate a statutory presumption that harm occurred.

This significantly assists claimants because proving the existence of an overcharge from the beginning can otherwise be extremely difficult.

The presumption does not mean that every claimant automatically receives damages.

The claimant still needs to establish the relevant loss and its relationship to the infringement.

9. The Role of the Federal Court of Justice

The Bundesgerichtshof (BGH) has played a particularly important role in developing German cartel-damages doctrine.

Its decisions address questions such as:

• who may sue;
• temporal application of cartel-damages provisions;
• causal connection;
• estimation of cartel overcharges;
• limitation;
• passing-on;
• the effect of competition-law infringements on downstream purchasers.

10. Important German Case Laws

1. BGH – ORWI / ORWI II

Significance

The ORWI litigation is one of the most important German authorities concerning claims brought by purchasers further down the supply chain.

The dispute concerned the effects of a cartel on downstream purchasers.

The BGH examined whether a purchaser that did not have a direct contractual relationship with the cartel participants could obtain damages.

Principle

The case demonstrates that German competition-law damages are not restricted simply to the cartel participant's immediate contractual customers.

The court focused on:

• economic harm;
• causal connection;
• the position of the claimant within the distribution chain;
• the relationship between the cartel infringement and the claimant's loss.

Importance for indirect purchasers

ORWI is particularly important because it helped establish the conceptual foundation for downstream claims in German cartel litigation.

11. 2. BGH – LKW-Kartell I

The truck cartel litigation is among the most significant modern German cartel-damages disputes.

The European Commission found that major truck manufacturers had participated in a long-running cartel.

Purchasers subsequently brought damages claims in Germany.

Importance

The litigation raised questions concerning:

• cartel overcharges;
• causal connection;
• estimation of damages;
• the significance of the Commission's infringement decision;
• the position of purchasers in the supply chain.

Indirect-purchaser relevance

Truck distribution commonly involves several commercial relationships.

Consequently, the case illustrates how cartel effects can propagate beyond the immediate contractual purchaser.

Principle

A competition-law damages action does not depend exclusively upon a direct contractual relationship with the cartel member.

The claimant's economic harm and its causal relationship with the infringement remain central.

12. 3. BGH – LKW-Kartell II

The subsequent truck-cartel jurisprudence further developed the German approach to damages.

The BGH addressed questions concerning the assessment and estimation of cartel damage.

Importance

The decision demonstrates that German courts can use economic estimation where exact quantification of the counterfactual competitive price is impossible.

This is particularly important for indirect purchasers.

An indirect purchaser may have difficulty proving:

cartel price → direct purchaser → distributor → retailer → claimant

with mathematical precision.

The court may nevertheless estimate the loss where sufficient factual and economic evidence exists.

13. 4. BGH – Schienenkartell

The Rail Cartel (Schienenkartell) litigation concerns cartel conduct involving rail products.

The cartel affected purchasers of products used in railway infrastructure.

Importance

The litigation illustrates the complexity of cartel damages where products move through different procurement and distribution structures.

It also demonstrates the importance of:

• market structure;
• procurement practices;
• price formation;
• individual purchasing relationships;
• economic evidence.

Indirect purchaser significance

Where a cartel's pricing effects move through intermediate commercial transactions, the ultimate purchaser may potentially establish damage despite not being the original customer of the cartel member.

14. 5. BGH – Möbelkartell

The Furniture Cartel (Möbelkartell) litigation provides another illustration of German private enforcement following cartel proceedings.

Furniture products can pass through several levels:

manufacturer → wholesaler → retailer → final customer

Therefore, the case provides a useful framework for analysing downstream economic effects.

Principle

The existence of intermediaries does not automatically sever causation.

Instead, the claimant must demonstrate that the infringement produced an economically relevant effect on the price ultimately paid.

15. 6. BGH – Zuckerkartell

The Sugar Cartel (Zuckerkartell) litigation is another important German cartel-damages context.

The underlying conduct concerned restrictions and coordination affecting the sugar market.

Importance

Sugar is a classic product capable of moving through multiple stages of commerce.

The economic impact may therefore extend from:

producer → industrial purchaser → processor → distributor → final purchaser.

This creates precisely the type of transmission problem encountered in indirect-purchaser litigation.

The case illustrates the importance of reconstructing the competitive price and analysing the transmission of cartel effects.

16. 7. BGH – Autoglas / Car Glass Cartel Litigation

German cartel-damages litigation concerning automotive glass is another important body of jurisprudence.

Automotive-glass cartel proceedings demonstrate the difficulty of determining whether cartel effects were incorporated into prices at different stages of commercial transactions.

Importance

The litigation raises questions concerning:

• market definition;
• overcharge;
• price effects;
• downstream transactions;
• economic modelling;
• causation.

For indirect purchasers, the key lesson is that a claimant cannot rely solely on the existence of a cartel.

There must be an economically defensible connection between the cartel and the claimant's loss.

17. 8. European Court of Justice – Kone

Although Kone is an EU case rather than a German national case, it is extremely important for German indirect-purchaser analysis.

The case concerned the so-called umbrella pricing effect.

A cartel may allow even non-cartel firms to charge higher prices because cartel conduct reduces competitive pressure in the market.

The Court of Justice recognised that such effects can potentially form the basis for damages.

Significance

The decision is important because it rejects an excessively narrow view of causation.

Competition-law harm may arise indirectly from cartel conduct.

The principle is particularly relevant when analysing:

• downstream purchasers;
• non-cartel suppliers;
• umbrella effects;
• complex supply chains.

18. 9. European Court of Justice – Sumal

Sumal concerns another important dimension of private competition-law enforcement: the identification of the undertaking responsible for damage within an economic unit.

The Court recognised circumstances in which liability can extend between entities forming part of the same economic unit.

Relevance

Although Sumal is not itself a classic indirect-purchaser case, it is relevant where a claimant seeks compensation from an undertaking other than the entity with which the claimant had a direct commercial relationship.

It therefore reinforces the broader principle that EU competition-law liability is not determined exclusively by formal contractual relationships.

19. Direct Purchaser vs Indirect Purchaser

20. Passing-On Defence

A particularly important issue is whether a defendant can argue:

"The claimant passed the overcharge on to its customers and therefore suffered no loss."

Modern German and EU law carefully regulates this argument.

The purpose is to avoid a situation where a direct purchaser obtains compensation despite having transferred the economic burden to someone else.

However, the existence of passing-on cannot automatically eliminate the possibility of a claim by an indirect purchaser.

The court must examine the actual economic chain.

21. Example of Passing-On

Suppose a cartel increases the manufacturer's price by:

€100 → €120

The manufacturer sells to a distributor.

The distributor passes €15 of the overcharge forward.

The retailer passes €10 onward.

The final consumer ultimately pays €120.

The distribution of the economic burden could be:

• manufacturer absorbs €5;
• distributor bears €5;
• retailer bears €5;
• consumer bears €5.

The precise allocation depends upon demand elasticity, pricing behaviour and market conditions.

This demonstrates why indirect-purchaser claims frequently require economic modelling.

22. Causation

German courts generally require a legally sufficient causal connection between:

competition infringement → price effect → claimant's loss.

For indirect purchasers, the causal chain can be longer:

Cartel
↓
Manufacturer's inflated price
↓
Distributor's purchase price
↓
Distributor's resale price
↓
Retailer's price
↓
Consumer's purchase price
↓
Consumer's loss

An intermediary does not automatically break causation.

However, the claimant must provide sufficient evidence to establish the connection.

23. Economic Evidence

Indirect-purchaser cases commonly rely on:

A. Before-and-after analysis

Prices before the cartel are compared with prices during or after the cartel.

B. Comparator markets

The affected market is compared with an unaffected market.

C. Regression analysis

Econometric techniques attempt to isolate the cartel's effect.

D. Cost and margin analysis

The court examines:

• production costs;
• distribution margins;
• resale margins;
• demand;
• market conditions.

E. Counterfactual modelling

The court reconstructs the likely competitive price absent the cartel.

24. Burden of Proof

The burden of proof is particularly important.

The claimant generally needs to demonstrate:

1. an infringement;
2. a legally relevant injury;
3. causal connection;
4. the amount or basis for estimating damage.

However, German cartel-damages legislation has introduced important presumptions and evidentiary mechanisms designed to overcome the informational disadvantages faced by private claimants.

This is especially significant because cartel participants normally possess much more information about:

• pricing;
• communications;
• sales volumes;
• margins;
• internal strategy;
• market conditions.

25. Disclosure of Evidence

Modern German cartel-damages law provides mechanisms for obtaining evidence from defendants and, under appropriate circumstances, third parties.

This can be critical for indirect purchasers because they may not possess documents demonstrating how the overcharge travelled through the supply chain.

Potential evidence includes:

• invoices;
• contracts;
• price lists;
• internal pricing documents;
• sales data;
• communications;
• accounting records;
• market studies.

26. Joint and Several Liability

Where several undertakings participate in a cartel, German law generally recognises joint and several liability, subject to statutory qualifications.

This is important for indirect purchasers because they may not know which cartel participant ultimately caused each portion of their loss.

The claimant can therefore potentially pursue an appropriate liable undertaking rather than reconstructing every economic transaction against every cartel participant.

27. Limitation Periods

Limitation is another major issue.

German cartel-damages claims are subject to specific statutory limitation rules.

The limitation framework has been modified significantly over time, particularly through implementation of EU private-enforcement requirements.

Claimants therefore need to establish:

• when they became aware of the infringement;
• when they became aware of the damage;
• the identity of the infringer;
• whether limitation was suspended or interrupted;
• the temporal applicability of amendments to the GWB.

28. Temporal Application

A major complication in German cartel litigation is that different versions of the GWB may apply depending upon when the infringement occurred.

This matters because German cartel-damages law has developed substantially through successive reforms.

Courts therefore frequently have to determine:

Which version of the GWB applies to the particular infringement and transaction?

This can materially affect:

• standing;
• presumptions;
• limitation;
• passing-on;
• burden of proof;
• damages.

29. Indirect Purchasers and the EU Principle of Effectiveness

German courts must interpret national competition-law rules consistently with EU competition law.

The EU principle of effectiveness is important.

National procedural rules cannot make the exercise of EU competition-law rights practically impossible or excessively difficult.

Therefore, German rules concerning standing, causation and evidence must be applied in a manner that preserves effective compensation for competition-law harm.

30. No Automatic Right Merely Because One Is an Indirect Purchaser

It is important not to overstate the position.

Being an indirect purchaser does not automatically establish entitlement to damages.

The claimant must still establish the elements necessary for compensation.

For example:

"I purchased a product ultimately affected by a cartel"

is not necessarily enough.

The claimant may need to demonstrate:

• that the cartel affected the relevant product;
• that the effect was transmitted;
• that the claimant actually paid an inflated price;
• that the infringement caused the relevant loss.

31. Standing and Passing-On Are Connected but Distinct

These concepts should not be confused.

Standing

asks:

Who may bring the claim?

Passing-on

asks:

Who ultimately bore the economic burden?

An indirect purchaser may have standing but still fail to prove that the overcharge reached its level of the supply chain.

Conversely, a direct purchaser may have a valid claim but have its damages reduced because part of the overcharge was passed downstream.

32. Importance for Digital Markets

The doctrine is increasingly important in digital and platform markets.

Consider:

Software provider → cloud distributor → enterprise customer → downstream business → consumer

If a dominant platform imposes an unlawful price or access restriction, economic harm may travel through several layers.

Similarly:

• app-store fees;
• advertising technology fees;
• cloud infrastructure charges;
• payment-processing fees;
• marketplace commissions

can potentially create downstream economic effects.

The indirect-purchaser framework therefore has significant implications for modern platform competition.

33. Relationship With Abuse of Dominance

Indirect-purchaser standing is not limited conceptually to classic cartels.

Competition-law damages can also arise from:

• abuse of dominance;
• exclusionary conduct;
• discriminatory pricing;
• unlawful tying;
• refusal to supply;
• exploitative pricing;
• exclusionary rebates.

However, the evidentiary framework differs depending upon the type of infringement.

Cartel cases generally benefit from stronger statutory presumptions concerning harm.

34. Key Case-Law Principles

The major authorities can be summarised as follows:

35. Legal Test for an Indirect Purchaser in Germany

A practical framework is:

Step 1 — Identify the infringement

↓

Was there a cartel or other competition-law violation?

↓

Step 2 — Identify the supply chain

Who purchased from whom?

↓

Step 3 — Identify the cartelised product

Was the claimant's product sufficiently connected to the infringement?

↓

Step 4 — Establish price effect

Did the infringement increase the relevant price?

↓

Step 5 — Establish transmission

Was the overcharge passed through the distribution chain?

↓

Step 6 — Establish claimant's loss

Did the claimant ultimately bear an economic loss?

↓

Step 7 — Quantify damage

How large was the overcharge actually borne?

↓

Step 8 — Apply limitation and statutory rules

Was the claim brought within the applicable period?

↓

Step 9 — Determine liable undertakings

Which cartel participants are legally responsible?

↓

Step 10 — Award damages

Compensation is awarded to the extent the claimant establishes compensable harm.

36. Critical Legal Issues

The most difficult questions in German indirect-purchaser litigation are therefore:

A. Causal distance

How many transactions can separate the claimant from the cartel before causation becomes too remote?

B. Overcharge transmission

How much of the original cartel overcharge reached the claimant?

C. Multiple intermediaries

How should courts calculate damage where there are several layers of distribution?

D. Elasticity

Did intermediaries absorb the overcharge or transfer it to customers?

E. Double recovery

How can courts prevent both direct and indirect purchasers from recovering the same loss?

F. Evidence asymmetry

How can a downstream purchaser obtain evidence predominantly held by cartel members?

G. Limitation

Which limitation regime applies to an older cartel?

37. Conclusion

German law does not adopt a simple contractual-privity rule that excludes indirect purchasers from cartel-damages claims. The modern framework under the GWB, influenced substantially by EU competition law and the Cartel Damages Directive, recognises that competition-law harm can travel through distribution chains.

The decisive issue is ultimately economic and causal harm.

An indirect purchaser must generally demonstrate that the competition infringement produced an overcharge or other compensable effect that was transmitted to the claimant and caused actual loss. German law has progressively strengthened the evidentiary position of victims through presumptions, disclosure mechanisms and judicial estimation of damages.

The jurisprudence surrounding ORWI, the truck cartel, Schienenkartell, Möbelkartell, Zuckerkartell and Autoglas, together with EU authorities such as Kone and Sumal, demonstrates a movement away from a purely contractual conception of competition-law injury toward a more economically grounded conception of who actually bears the harm.

Thus, the central principle can be stated as:

Indirect purchaser status does not itself create liability, but neither does the absence of a direct contractual relationship defeat a competition-law damages claim. The decisive question is whether the claimant can establish legally sufficient causal and economic harm resulting from the infringement.
