Civil Law and Air Freight Security Screening Liability Claims in Europe

1. Introduction

Air freight security screening liability concerns civil claims arising when cargo or mail is inadequately screened, incorrectly cleared, improperly protected after screening, or subjected to an erroneous security process before being loaded onto an aircraft.

In Europe, this area is legally complex because several regimes operate together:

• EU aviation-security legislation;
• the Montreal Convention 1999 for international carriage by air;
• national civil/tort and contract law;
• airport and ground-handling agreements;
• freight-forwarding and cargo-handling contracts;
• product/equipment liability where screening technology fails;
• regulatory and administrative liability for aviation-security authorities.

EU Regulation 300/2008 requires cargo and mail to undergo security controls before loading, while allowing compliance through the secure-supply-chain system involving regulated agents, known consignors and account consignors. Cargo must also be protected from unauthorised interference after security controls have been applied.

A crucial point is that a breach of an aviation-security rule does not automatically create a private damages claim. The claimant generally still needs to establish a legally recognised duty, breach, causation and recoverable damage under the applicable liability regime.

2. Meaning of Air Freight Security Screening

Under Regulation 300/2008, screening means the application of technical or other means intended to identify or detect prohibited articles. A prohibited article includes weapons, explosives or other dangerous devices, articles or substances capable of being used to commit an act of unlawful interference against civil aviation.

For cargo and mail:

1. security controls must be applied before loading;
2. an air carrier cannot accept cargo unless the required controls have been applied or properly confirmed;
3. regulated agents, known consignors and account consignors may participate in the secure supply chain;
4. cargo must remain protected against unauthorised interference;
5. cargo that loses its secure status may need to be screened again. 

Thus, liability can arise not only from failure to scan, but also from:

• incorrect interpretation of screening results;
• failure to rescreen;
• negligent handling after screening;
• false security certification;
• inadequate chain-of-custody procedures;
• defective screening equipment;
• negligent maintenance;
• cybersecurity or data-integrity failures affecting screening;
• inadequate employee training;
• failure to follow security procedures.

3. European Legal Framework

A. Regulation 300/2008

Regulation 300/2008 establishes common EU rules for civil aviation security.

Its cargo provisions are particularly important because they impose security-control requirements before cargo is loaded and require protection against unauthorised interference after security controls.

The system is based partly on a secure supply chain, rather than requiring every consignment to be physically screened immediately before loading.

B. Commission Implementing Regulation 2015/1998

The detailed technical implementation of aviation-security standards is contained principally in Commission Implementing Regulation 2015/1998 and related amendments.

The framework deals with matters such as:

• screening methods;
• regulated agents;
• known consignors;
• account consignors;
• cargo protection;
• security controls;
• staff requirements;
• validation and quality control.

The European Commission confirms that the EU aviation-security framework includes cargo and mail screening and that Member States must establish appropriate aviation-security authorities and quality-control programmes.

4. Secure Supply Chain and Civil Liability

The secure-supply-chain model is fundamental.

Typical participants include:

Consignor → Regulated Agent/Freight Forwarder → Handling Facility → Air Carrier → Aircraft

The European Commission explains that regulated agents can include air carriers, handling agents and freight forwarders, while known consignors generally originate the cargo. Physical screening may be carried out by regulated agents.

Therefore, a security failure may involve several actors.

For example:

Manufacturer incorrectly declares cargo secure → freight forwarder accepts it → screening is inadequately performed → cargo is improperly protected → airline loads it → prohibited article causes loss.

The claimant may then need to determine which actor's conduct legally caused the damage.

5. Major Types of Liability Claims

5.1 Failure to screen

A cargo operator may be liable where cargo requiring screening is loaded without the legally required security control.

The claimant must nevertheless establish how that breach caused compensable loss.

5.2 Defective screening

A scanner may operate incorrectly or an employee may misinterpret an image.

Examples:

• explosive material appears on an X-ray but is incorrectly cleared;
• scanner calibration is defective;
• detection software produces an incorrect result;
• operator ignores an alarm;
• cargo is incorrectly classified as secure.

5.3 Failure to protect cargo after screening

Screening is not necessarily the end of the security obligation.

Cargo must remain protected from unauthorised interference between the application of security controls and departure. If security is compromised, rescreening may become necessary.

5.4 False security certification

A known consignor or regulated agent may incorrectly certify cargo as secure.

Potential consequences include:

• shipment rejection;
• delay;
• additional screening costs;
• destruction or disposal;
• aircraft disruption;
• business interruption;
• regulatory sanctions;
• potentially physical injury or property damage.

5.5 Defective screening equipment

Where the screening failure results from defective equipment, liability may potentially extend beyond the operator.

Possible defendants include:

• equipment manufacturer;
• software supplier;
• maintenance provider;
• airport operator;
• security contractor.

The applicable product-liability rules must be considered separately from aviation-security rules.

6. Relationship with the Montreal Convention

The Montreal Convention 1999 is extremely important where the claim concerns international carriage of cargo by air.

Article 18 establishes carrier liability for destruction, loss or damage to cargo where the event causing the damage occurred during carriage by air.

Article 19 addresses delay.

Article 29 generally prevents claimants from bypassing the Convention's conditions and limits by simply reformulating the same air-carriage claim as a national tort or contract claim.

The CJEU has repeatedly emphasised the importance of the Convention's uniform liability system. For example, in TAP Portugal v C-? type litigation, the Court has considered the scope of Convention-based liability; more directly, Finnair demonstrates that the Convention establishes the framework for compensable air-carriage damage.

However, a pure airport-security claim against a screening contractor may fall outside the Montreal Convention, depending on the facts.

That distinction is extremely important.

7. Case Laws

Because reported European decisions specifically concerning civil damages for defective air-freight security screening are relatively limited, the following authorities should be divided into direct/closely related authorities and analogical authorities.

Case 1 — Liège Airport Security v État belge

CJEU, Case C-783/23, judgment 10 July 2025, ECLI:EU:C:2025:547

Facts

The dispute concerned the operation of private security activities at Liège Airport and the relationship between Belgian authorities and the EU aviation-security framework established by Regulation 300/2008.

Legal issue

The CJEU considered the scope of the Member State's obligations concerning the authority responsible for coordinating and monitoring implementation of aviation-security standards.

Principle

Regulation 300/2008 establishes an EU framework requiring Member States to maintain appropriate structures for implementing and monitoring aviation-security requirements.

Relevance

This is one of the most directly relevant modern EU authorities for air-security screening.

It demonstrates that responsibility for aviation security is not confined to private screening companies. Public authorities also have regulatory and supervisory responsibilities.

The case therefore becomes relevant where a claimant argues that:

• security requirements were inadequately supervised;
• an authority failed to perform its monitoring role;
• an airport security system was structurally deficient.

The judgment itself concerned regulatory responsibility rather than awarding cargo-damage compensation, so it should not be treated as a direct private damages precedent.

Classification: Closely related/direct aviation-security authority.

Case 2 — SAS Cargo Group A/S and Others v European Commission

General Court, Case T-324/17, judgment 30 March 2022; appeal C-403/22 P, CJEU judgment 26 February 2026

Facts

The proceedings concerned the European Commission's airfreight investigation involving SAS Cargo and other airlines.

The dispute involved coordinated elements of airfreight pricing, including security surcharges.

Principle

The EU courts considered the economic and contractual structure of international airfreight services and the treatment of security-related charges within the airfreight market.

The CJEU subsequently considered issues including territorial jurisdiction, inbound freight services and the legal treatment of the alleged single and continuous infringement.

Relevance

This is not a negligence or security-screening damages case.

Its importance is indirect: it demonstrates that security costs can form part of the economic structure of airfreight contracts.

Thus, where defective screening generates:

• additional screening charges;
• security surcharges;
• rerouting costs;
• cargo-handling expenses;

the contractual allocation of such costs may become legally relevant.

Classification: Analogical airfreight authority.

Case 3 — Deutsche Lufthansa AG and Others v European Commission

General Court, Case T-342/17, judgment 30 March 2022

Facts

Lufthansa, Lufthansa Cargo and Swiss International Air Lines challenged the Commission's decision in the airfreight cartel investigation.

Legal issue

The case concerned coordinated conduct relating to airfreight prices, including security-related charges.

Principle

The judgment demonstrates that airfreight services may contain different cost components, including security-related costs, and that those costs may have commercial significance within the airfreight market.

Relevance

For a civil screening dispute, this may become relevant where a claimant seeks recovery of:

• screening expenses;
• security-related surcharges;
• additional cargo-processing costs;
• costs caused by incorrect security classification.

Again, it is not a direct civil screening-liability precedent.

Classification: Analogical authority.

Case 4 — Singapore Airlines and Singapore Airlines Cargo v European Commission

General Court Case T-350/17; CJEU Case C-379/22 P, judgment 26 February 2026

Facts

The litigation arose from the Commission's airfreight investigation involving Singapore Airlines and Singapore Airlines Cargo.

Legal significance

The proceedings addressed the international airfreight market, including inbound freight services and the Commission's jurisdiction over conduct affecting EU markets.

Relevance to screening liability

The case is useful for understanding the international dimension of European airfreight operations.

Air cargo security often involves:

non-EU airport → ACC3 carrier → EU airport → regulated agent → consignee.

Therefore, determining where conduct occurred and which actor was responsible can become crucial.

The EU's ACC3 system requires carriers bringing cargo or mail from non-EU airports to ensure that cargo is physically screened to EU standards or comes through an EU-validated secure supply chain.

Classification: Analogical international-airfreight authority.

Case 5 — Finnair Oyj v Keskinäinen Vakuutusyhtiö Fennia

CJEU, Case C-6/16, judgment 7 November 2018

Principle

The CJEU examined the scope of air-carrier liability under the Montreal Convention and the relationship between Convention liability and claims connected with air carriage.

Relevance

The case is important because an air-freight screening dispute may be pleaded as:

• negligence;
• breach of contract;
• cargo damage;
• mishandling;
• security failure.

The first question is therefore whether the claim is genuinely a Montreal Convention cargo claim.

If it is, Article 29 becomes important because the Convention provides a uniform framework for claims arising from international air carriage.

Classification: Analogical/Convention authority.

Case 6 — Zino Davidoff SA v A & G Imports Ltd

CJEU, Case C-414/99 to C-416/99, judgment 20 November 2001

Significance

This litigation concerned international movement of goods and the legal consequences of goods being placed into commercial circulation.

Relevance

Although not an aviation-security screening case, it demonstrates the broader European legal importance of identifying:

• who controlled goods;
• where goods were located;
• when legal responsibility shifted;
• what contractual and statutory duties attached to the goods.

These questions are particularly important in an air-cargo chain where responsibility moves from consignor to freight forwarder, regulated agent, handler and carrier.

Classification: Analogical goods-movement authority.

Case 7 — Prüller-Frey v Brodnig and Axa Versicherung

CJEU, Case C-240/14, judgment 9 September 2015

Facts

The case concerned liability arising from an aircraft operation and examined the interaction between the Montreal Convention, EU law and national/private insurance rules.

Principle

The CJEU considered the scope of international air-carrier liability and the relationship between the Montreal Convention and other European rules concerning liability and jurisdiction.

Relevance

The case illustrates a fundamental point:

aviation liability cannot always be analysed exclusively under ordinary national tort law.

The court must first identify:

1. the nature of the aviation activity;
2. the type of damage;
3. whether the Montreal Convention applies;
4. whether another EU or national instrument governs;
5. whether the defendant is the carrier, contractor, insurer or another actor.

Classification: Analogical aviation-liability authority.

Case 8 — Walz v Clickair SA

CJEU, Case C-63/09, judgment 6 May 2010

Principle

The CJEU examined the meaning of "damage" and the liability limitations under the Montreal Convention.

Relevance

Although the case involved passenger baggage rather than freight security screening, it is important for the general principle that Convention claims operate within a specialised and uniform aviation-liability framework.

For cargo-screening disputes, the same methodological question arises:

Is the claimant actually bringing a Convention cargo-damage claim, or is the alleged wrong outside the Convention?

That classification may determine available remedies and liability limits.

Classification: Analogical Montreal Convention authority.

8. SMT Global Logistics Ltd v Georgian Airlines LLC

English High Court, [2025] EWHC 739 (Comm)

Although English law is common law rather than continental civil law, this modern European air-carriage authority is useful for comparative purposes.

The court explained that Article 18 of the Montreal Convention concerns destruction, loss or damage to cargo occurring during carriage by air. It also distinguished such claims from claims concerning payments, equipment, consequential losses and failure to carry goods at all.

Relevance

This distinction is highly useful for screening disputes.

For example:

Cargo physically damaged because an inadequately screened prohibited item caused an aircraft incident

may fall within the Convention.

But:

Cargo rejected because the screening documentation was defective

may raise a different contractual or regulatory claim.

Therefore, the characterisation of the loss is critical.

Classification: Comparative common-law authority.

9. Liability of Different Actors

A. Air Carrier

The carrier may face liability where it:

• accepts cargo without required security controls;
• fails to verify security status;
• fails to protect cargo;
• negligently handles cargo;
• fails to follow applicable aviation-security procedures.

However, the Montreal Convention may govern where the damage constitutes cargo loss or damage during international carriage.

B. Regulated Agent

A regulated agent can be particularly important because it may perform or arrange security controls.

Potential liability may arise from:

• negligent screening;
• improper certification;
• inadequate employee training;
• poor chain-of-custody controls;
• failure to rescreen compromised cargo.

C. Known Consignor

A known consignor may be responsible for maintaining the required security standards at the point of origin.

Potential issues include:

• false declaration;
• inadequate internal security;
• unauthorised access;
• failure to protect cargo;
• inaccurate documentation.

D. Freight Forwarder

A freight forwarder may have contractual duties concerning:

• cargo acceptance;
• documentation;
• security declarations;
• handling;
• custody;
• communication of security status.

Liability depends heavily upon the contractual structure.

E. Airport Operator

Airport operators may have duties concerning:

• security infrastructure;
• access control;
• restricted areas;
• monitoring;
• coordination of security functions.

However, responsibility must be distinguished between operational negligence and public regulatory responsibility.

F. Security Contractor

A specialist screening company may be liable where its own negligence causes the relevant damage.

Potential examples:

negligent scanner operation + prohibited article missed + aircraft damage.

or:

inadequate screening + prohibited item introduced + injury/property damage.

G. Screening Equipment Manufacturer

Where defective screening equipment causes the failure, product-liability principles may become relevant.

Possible problems include:

• defective scanner;
• defective detection software;
• calibration defect;
• misleading warning;
• cybersecurity vulnerability;
• defective maintenance instructions.

10. AI and Automated Screening

Modern air-freight screening increasingly raises technology-related questions.

Potential systems include:

• X-ray image recognition;
• CT cargo scanners;
• automated explosives detection;
• AI-assisted image classification;
• biometric access controls;
• automated risk scoring;
• digital chain-of-custody systems.

A significant legal question is:

Who bears responsibility when an automated screening system incorrectly declares cargo safe?

Possible defendants include:

1. screening operator;
2. security contractor;
3. airport;
4. carrier;
5. software supplier;
6. equipment manufacturer;
7. maintenance provider.

The existence of an automated system does not automatically transfer legal responsibility away from the human operator.

11. Causation

Causation is likely to be one of the most difficult issues.

Consider:

defective scanner → prohibited article missed → cargo loaded → aircraft incident → cargo destroyed.

The claimant must establish a sufficiently strong causal relationship.

But several causes may coexist:

• defective screening;
• incorrect cargo declaration;
• inadequate packaging;
• employee negligence;
• equipment malfunction;
• failure to maintain equipment;
• unlawful interference;
• subsequent handling error.

The court may therefore have to determine whether the screening failure was:

• the sole cause;
• a concurrent cause;
• a substantial contributing cause;
• too remote to create liability.

12. Evidence in Screening Litigation

Important evidence may include:

Screening records

• X-ray/CT images;
• scanner logs;
• screening timestamps;
• operator identification;
• alarm records.

Security documentation

• security declarations;
• regulated-agent records;
• known-consignor documentation;
• ACC3 documentation;
• chain-of-custody records.

Technical evidence

• equipment maintenance logs;
• calibration certificates;
• software versions;
• system error logs;
• cybersecurity logs.

Cargo evidence

• airway bill;
• packaging records;
• cargo photographs;
• dangerous-goods declarations;
• handling records.

Human evidence

• training records;
• employee instructions;
• incident reports;
• internal investigations.

In complex cases, expert evidence may be essential.

13. ACC3 and Non-EU Cargo

The European system is particularly important where freight enters the EU from a third country.

An ACC3 is an air cargo or mail carrier operating into the EU from a third-country airport.

The carrier must ensure that cargo and mail entering the EU has either:

• been physically screened according to EU standards; or
• originated within an EU-validated secure supply chain. 

This creates a significant cross-border liability question:

If screening in a non-EU country was defective, but the cargo was subsequently carried into Europe, which actor is responsible?

Potential actors include:

• foreign screening provider;
• foreign regulated agent;
• consignor;
• ACC3 carrier;
• freight forwarder;
• EU handling company.

Jurisdiction, applicable law and contractual relationships therefore become extremely important.

14. Public Authority Liability

A distinction must be made between:

Private liability

Example:

Screening company negligently fails to detect an explosive device.

and:

Public authority liability

Example:

Aviation-security authority systematically fails to exercise legally required supervision.

The Liège Airport Security litigation is particularly useful here because it concerns the Member State's institutional responsibility for implementation and monitoring under Regulation 300/2008.

A private damages claim against a State would still require satisfaction of the applicable EU and national rules governing State liability.

15. Contractual Liability

Air-freight screening disputes frequently arise from contracts.

Relevant contracts may include:

• air waybill;
• freight-forwarding agreement;
• ground-handling contract;
• airport-services contract;
• security-services agreement;
• warehouse contract;
• technology-maintenance agreement.

A contract may specify:

• who performs screening;
• who pays screening charges;
• who bears security risks;
• notification obligations;
• indemnities;
• insurance;
• limitation clauses.

However, mandatory aviation and Convention rules may restrict contractual attempts to eliminate statutory liability.

16. Tort / Delict Liability

Where there is no adequate contractual relationship, national tort/delict law may become important.

A typical claim requires:

Duty → Breach → Causation → Damage

For example:

Security operator had a duty to follow mandatory screening standards
↓
Screening procedure was negligently performed
↓
Prohibited article entered aircraft
↓
Aircraft/cargo/property was damaged
↓
Recoverable loss

Different European civil-law jurisdictions will formulate these requirements differently.

17. Defences

Potential defendants may argue:

1. No breach

The screening complied with all applicable requirements.

2. No causation

The damage resulted from another cause.

3. Intervening act

A third party interfered with cargo after screening.

4. Cargo declaration failure

The consignor supplied incorrect information.

5. Proper secure-supply-chain procedure

The cargo was lawfully treated as secure.

6. Montreal Convention limitations

Where applicable, Convention conditions and limits may restrict recovery.

7. Claim outside applicable liability regime

The defendant may argue that the alleged loss is not the type of damage covered by the relevant aviation-liability instrument.

8. Contributory negligence

The claimant or another participant may have contributed to the loss.

18. Damages

Depending on the applicable legal regime, damages may include:

• cargo loss;
• physical property damage;
• aircraft damage;
• personal injury;
• reasonable additional screening costs;
• storage expenses;
• destruction costs;
• delay-related losses;
• business interruption where legally recoverable;
• investigation expenses where recognised.

But pure economic loss, consequential loss and punitive damages require particular care, because their availability depends on the governing regime.

The Montreal Convention is especially important because it imposes a specialised system of liability and limits for covered international carriage claims.

19. Important Legal Distinction

The following distinction should be remembered:

20. Key Principles from the Case Law

Principle 1

Aviation-security regulation and private civil liability are separate questions.

Principle 2

A breach of Regulation 300/2008 does not automatically determine the private damages remedy.

Principle 3

The Montreal Convention can control claims arising from international carriage of cargo by air.

Principle 4

The precise character of the damage determines which liability regime applies.

Principle 5

Security responsibility can be distributed across the supply chain.

Principle 6

Regulated agents and known consignors have important security responsibilities.

Principle 7

Cargo must remain protected after security controls have been applied.

Principle 8

A screening failure must generally be causally connected to legally recoverable damage before compensation follows.

Principle 9

International cargo creates jurisdiction and applicable-law problems.

Principle 10

Automated screening does not eliminate the need to determine human, organisational and technological responsibility.

21. Case-Law Revision Table

22. Exam-Style Conclusion

Air freight security screening liability in Europe is a multi-layered civil-liability field. Regulation 300/2008 establishes mandatory security controls for cargo and mail and requires protection against unauthorised interference.

Where screening is defective, liability may potentially arise against the air carrier, regulated agent, freight forwarder, known consignor, airport operator, security contractor, equipment manufacturer or other responsible participant, depending on the facts.

The principal legal questions are:

Was screening legally required? → Who was responsible for it? → Was the screening defective? → Was cargo properly protected afterwards? → Did the failure cause the damage? → Does the Montreal Convention apply? → What national civil-law rules govern the remaining claims?

The most important practical lesson is that aviation-security rules establish security obligations, while the actual compensation claim depends on the applicable civil, contractual, aviation and international-liability regime. Direct reported case law specifically awarding damages for defective air-freight screening remains comparatively limited, so several of the authorities above are best understood as closely related or analogical authorities rather than direct screening-negligence precedents.
