LAWS90064 Chap.8 Private Enforcement and Cartel Damages
Private Enforcement and Cartel Damages
Private enforcement can pursue deterrence, compensation, disgorgement and development of legal doctrine. This chapter builds the claimant's causal chain from infringement through market effect and affected transaction to counterfactual loss and remedy.
It compares deterrence and compensation oriented design choices, explains pass on and duplicate recovery, and integrates private claims with public findings, leniency, disclosure and the sequencing of investigations. A finding of infringement does not itself quantify an individual claimant's loss. The claimant still needs evidence connecting the conduct to the relevant market, transaction and counterfactual price or output.
Benchmark choice must account for cost, demand and market changes that are not caused by the cartel. Distribution also matters because an overcharge may be retained, passed downstream or accompanied by lost sales. Procedural rules determine whether dispersed losses can be pursued without duplicating recovery or undermining evidence supplied to public authorities.

Key terms
- Private enforcement
- Legal action by private parties seeking remedies for loss or other consequences of cartel conduct.
- Follow on claim
- A private action relying on a prior public infringement finding within the legal scope given to that finding.
- Counterfactual
- The market or transaction outcome likely to have existed if the cartel conduct had not occurred.
- Overcharge
- The difference between the price paid and the estimated competitive price in the counterfactual world.
- Pass on
- The extent to which a purchaser transfers an overcharge to downstream customers through higher prices.
Private Enforcement and Cartel Damages FAQ
What must a private claimant prove?
The claimant should connect the infringement to a market effect, the market effect to its affected transaction and that transaction to measurable counterfactual loss. A public decision can support one link without automatically proving all later links.
Why is the counterfactual important?
Damages compare the observed outcome with what probably would have happened without the cartel. Benchmark choice, comparability and controls for costs or demand determine the estimate, so assumptions should be disclosed and tested.
How do public and private enforcement interact?
Public cases can generate findings and evidence used by claimants, while disclosure or damages exposure can alter leniency incentives. Good design considers sequencing, confidentiality, claimant access, duplication and the objectives assigned to each system.
What does pass on change?
Pass on affects where the overcharge is retained and who may have suffered loss. The analysis must also consider reduced sales, downstream claims and mechanisms that prevent the same overcharge from being recovered twice.
Why can a public finding be insufficient for damages?
A public decision may establish coordinated conduct across a market or period without identifying every affected purchase or loss. Private proof must connect the claimant's transaction to impact, causation and a defensible estimate.
Assessment move
Memorise the causal chain: infringement, market effect, affected transaction, counterfactual loss and remedy. For each case, write the evidence supporting every link. Compare private systems through their objectives and procedures rather than labels. Practise choosing a benchmark and naming the assumption that could change the estimate. In pass on problems, consider both retained overcharge and lost volume.
Close every answer with the effect on public detection, leniency and evidence, because private remedies operate inside the wider enforcement system. Create a transaction table showing date, product, purchaser, observed price, proposed benchmark and data limitation. Then test the same claim under a before and after benchmark and a comparator market, explaining what each controls for poorly.
Map direct and indirect purchasers separately so that standing, pass on and duplicate recovery do not merge. For procedure questions, state which evidence remains confidential, which public findings carry weight and when disclosure should occur. Run a sensitivity drill using two plausible benchmarks and record which cost, demand or product-mix assumptions change the result.
Do not average the estimates without justification; explain which comparison better approximates the world without the infringement. Add a recovery map linking direct purchasers, indirect purchasers and lost-volume claims. Check the map for gaps and duplicate recovery before choosing collective or individual procedure. End by identifying the public evidence that narrows, but does not complete, claimant proof.
