Short answer
Before signature, EU remedies law is designed to keep a procurement reversible. An interested person who was or risks being harmed must have rapid review. The system must be able to suspend the procedure and set aside unlawful decisions. An award normally cannot be signed during standstill; when an independent first-instance body reviews it, signature remains suspended until the body rules on interim relief or review.
After signature, the remedy depends on the infringement. National law may often limit relief to damages. But an independent review body must order, or produce, ineffectiveness for specified serious breaches—principally an unlawful direct award, and certain standstill or suspension breaches combined with a substantive procurement infringement that harmed the challenger's chance of winning. Overriding public-interest reasons can justify maintaining the contract, but then effective alternative penalties are required. Those penalties are a fine or shortening the contract, not damages alone.
National law supplies detailed standing, deadlines, procedure, damages tests and effects of ineffectiveness. A challenger should immediately identify the award, signature and performance dates.
The governing remedies framework
Directive 89/665/EEC governs review of public-sector procurements. Directive 92/13/EEC provides the parallel system for utilities. Both were substantially strengthened by Directive 2007/66/EC. The rules apply alongside the substantive procurement directives and national procedural law.
The framework preserves pre-signature challenges through interim relief or annulment, and provides damages or, for designated serious breaches, ineffectiveness or alternative penalties. Rapid review must be available at least to an interested person who was or risks being harmed.
Before signature: preserve a real chance to win
Article 2(1) of Directive 89/665 requires powers to grant interim measures, set aside unlawful decisions and award damages. Interim powers include suspending the award procedure or implementation of a contracting authority's decision. Setting aside may include removing discriminatory specifications.
The distinction between the award decision and the later contract matters. In Alcatel Austria, the Court held that the decision selecting the successful tenderer must be open to a procedure capable of setting it aside before the contract is concluded. A system in which award and signature occur simultaneously deprives disappointed tenderers of meaningful pre-contract review.
The award decision must be open to review “prior to the conclusion of the contract”. —
An applicant does not automatically receive every interim measure. Except for the specific automatic suspensions in the directives, national law may allow the review body to balance probable consequences for all interests and the public interest. It may refuse relief where negative consequences exceed the benefits. That refusal cannot extinguish other claims.
Standstill and automatic suspension
Article 2a normally prohibits signature for at least 10 calendar days beginning the day after electronic transmission of the award decision. Where other communication is used, the minimum is generally 15 days after sending or 10 days after receipt. The notification must contain the relevant reasons and precise applicable standstill period.
Limited derogations cover certain procedures requiring no prior EU notice, a single concerned tenderer with no concerned candidate, and specified framework or dynamic-purchasing awards. National law may impose longer periods or fewer derogations.
When an independent first-instance review body is examining an award decision, Article 2(3) prevents signature until that body decides the application for interim measures or review. In CROSS Zlín, C-303/22, the Court confirmed that the body need not be judicial and EU law does not require that automatic bar to continue after its decision. A required initial complaint to the authority must suspend signature for the prescribed period.
Filing does not always suspend every step. Identify the statutory suspension and, if necessary, seek an interim order.
Setting aside unlawful decisions
Before signature, the review body must be able to set aside unlawful exclusions, scoring, awards or discriminatory terms. Depending on the defect and national rules, reevaluation, bidder restoration, removal of a specification, cancellation or a new procedure may follow.
EU law does not mean every breach automatically awards the contract to the claimant. The review body corrects the unlawful decision and preserves equal competition. It must consider causation and the procedural position actually lost.
Time is critical. In Uniplex, the Court held that a period for seeking a declaration of infringement or damages must run from when the claimant knew or ought to have known of the infringement. An open-ended national rule requiring proceedings “promptly” was too uncertain. Current national rules may set very short, fixed periods, so bidders should not wait for informal negotiations.
Time runs from when the claimant “knew, or ought to have known” of the infringement. —
After signature: damages may be the ordinary remedy
Subject to the special ineffectiveness rules, Article 2(7) leaves the effects of review on a signed contract to national law. A Member State may provide that, after a lawfully permitted signature, review powers are limited to damages. It may also require the unlawful decision to be set aside before damages are claimed.
The directives require damages but do not fully harmonise liability or valuation. In Spijker, the Court confirmed that national law supplies the details, subject to equivalence, effectiveness and EU State-liability principles. In INGSTEEL, C-547/22, it held that national law cannot categorically exclude compensation for loss of an opportunity to participate in the procedure. Infringement, compensable loss and causation still have to be established.
National procedure cannot turn the damages remedy into an illusion. In MedEval, EU effectiveness precluded a system that required a prior declaration of an unlawful direct award but imposed a six-month period running from signature regardless of whether the injured party knew of the infringement. Secret awards are a particular warning: discovery, declaratory and damages deadlines must all be checked immediately.
When ineffectiveness is required
Article 2d requires an independent review body to declare a contract ineffective, or make ineffectiveness result from its decision, in defined cases. The central grounds are:
- the contract was awarded without the required prior publication in the Official Journal and no lawful direct-award exception applied;
- a standstill or automatic-suspension infringement deprived the challenger of pre-contract remedies, combined with a substantive procurement infringement that affected its chance of obtaining the contract; or
- a Member State used specified standstill derogations for certain framework or dynamic-purchasing awards and the underlying award rules were infringed.
Not every standstill error therefore makes a contract ineffective. For the combined-breach ground, the procedural violation, substantive violation and effect on the challenger's chances must all be established.
A properly used voluntary ex ante transparency notice can protect an intended direct award from ineffectiveness where the authority genuinely considered it lawful, published the prescribed notice and waited at least 10 days. That safe harbour is not permission to disguise a direct award; its conditions are reviewed strictly.
Maintaining or shortening the contract
National law determines whether ineffectiveness operates retroactively or only terminates obligations still to be performed. If cancellation is limited prospectively, alternative penalties must address the part left intact.
A review body may maintain an unlawfully awarded contract where overriding reasons relating to a general interest require it after examination of all relevant circumstances. Ordinary costs of delay, retendering, changing supplier or the contract's own legal obligations are direct economic interests and normally do not qualify. Exceptional disproportionate consequences may be considered within the directive's narrow test.
Where ineffectiveness is displaced, or for specified standstill infringements not meeting its full conditions, Article 2e requires effective, proportionate and dissuasive alternative penalties. The permitted penalties are:
- a fine imposed on the contracting authority; or
- shortening the duration of the contract.
Damages to the claimant are separate and do not themselves count as an adequate alternative penalty.
Deadlines for ineffectiveness
Article 2f permits national law to impose a period of at least 30 days after a compliant award notice explaining the direct award, or after affected tenderers and candidates are informed of the contract with relevant reasons. In any event, national law may impose a long-stop period of at least six months from the day after signature. Other review periods are governed by national law subject to the directive's minimum rules.
These are EU minima, not a universal calendar. Consult current national legislation and review-body rules, assuming the earliest plausible deadline controls.
A practical remedies checklist
- Record when each decision, reasons and contract notice was received or published.
- Confirm whether the contract has been signed and whether performance has started.
- Identify the relevant public-sector or utilities remedies directive and national implementing law.
- Determine whether standstill or an automatic suspension is running.
- Seek interim relief expressly if filing alone does not suspend the relevant act.
- Separate requests to set aside a decision, declare ineffectiveness and recover damages.
- For a signed contract, test each Article 2d element rather than assuming any breach suffices.
- File against the shortest defensible national deadline.
Conclusion
EU procurement remedies preserve reversibility before signature and calibrate consequences afterwards. Review bodies must be able to stop and set aside unlawful awards while competition can be restored. After signature, damages may be ordinary, but serious direct-award and combined standstill breaches trigger ineffectiveness unless narrow public-interest grounds justify alternative penalties.
The practical outcome depends on timing. A bidder that identifies the decision, signature, notice and knowledge dates early has far more remedial options than one that challenges only after performance is advanced.
