Ineffectiveness in Public Procurement 2026

Ineffectiveness in public procurement: when is a public contract void by operation of law? Triggering events, legal consequences and cure options explained concisely.

Definition: Ineffectiveness in public procurement refers to the absolute invalidity of a public contract that arises by operation of law where the contracting authority has breached certain fundamental procurement rules — in particular by awarding the contract without the prescribed procedure or in disregard of the standstill period.

What is ineffectiveness in public procurement?

The ineffectiveness of a contract concluded in breach of procurement law is the harshest sanction in procurement law and is intended to ensure that public contracting authorities cannot circumvent procurement rules simply by concluding a contract. Until the introduction of the Remedies Directive 2007/66/EC (which entered into force in Germany in 2009 and in Austria in 2010), a public contract that had already been concluded could in principle no longer be set aside — an unlawfully acting contracting authority had effectively created a "fait accompli". Since the reform, ineffectiveness has been a central instrument of procurement-law protection.

Grounds for ineffectiveness

Ineffectiveness arises in specific, statutorily defined cases.

1. Award without the prescribed procedure (de facto award)

The contracting authority concludes a contract without first publishing a contract notice required in the EU above-threshold range. This is the classic case of "de facto award" or unlawful direct award.

2. Breach of the standstill period

The contracting authority concludes the contract before expiry of the standstill period following information of unsuccessful bidders (§ 135(1) no. 2 GWB; § 334(1) no. 2 BVergG 2018).

3. Further triggering events

Unlawful call-offs from framework agreements
Breaches of the principle of transparency within a dynamic purchasing system

Legal consequences of ineffectiveness

A void contract is invalid from the outset (ex tunc) — performance already rendered must be unwound according to the principles of unjust enrichment. In practice this is often complex, particularly where works have already been carried out. The review body (the procurement review chamber in Germany; BVwG in Austria) can declare ineffectiveness and make corresponding orders. For contracts already performed, ex nunc effect (effect from the moment of decision) may be ordered for reasons of proportionality.

Cure of ineffectiveness

Ineffectiveness may exceptionally be averted by a voluntary ex-ante transparency notice. If the contracting authority publishes a corresponding notice on TED before contract conclusion and observes the minimum standstill period of 11 days without a review application being filed, the contract can no longer be declared ineffective (Art. 2d(4) Directive 89/665/EEC; § 135(3) GWB).

In addition, the review body may, on overriding grounds in the general interest, refrain from declaring ineffectiveness but must then impose alternative sanctions (e.g. fines, shortening of the contract term).

Distinction from other grounds of invalidity

Procurement-law ineffectiveness is to be distinguished from general civil-law nullity (e.g. § 879 ABGB, § 134 BGB). Procurement-law ineffectiveness can be declared only by the competent procurement-review bodies; civil courts are usually not competent where the procurement-review procedure takes precedence.

FAQ

Who can rely on ineffectiveness? Excluded bidders may file an application for declaration of ineffectiveness with the competent review body (Germany: procurement review chamber; Austria: BVwG or regional procurement office).

Is there a time limit for the application? Yes. In Germany the application must be filed within 30 calendar days of becoming aware of the breach (§ 135(2) GWB), but no later than six months after conclusion of the contract or 30 days after EU-wide publication.

What happens to services already provided? Services already rendered must be unwound under the rules on unjust enrichment. For works contracts the review body may also order a modified legal effect.
