Obligation to Object in Procurement Law 2026 – Deadlines and Preclusion

The obligation to object requires bidders to object to identified procurement violations in time. Violations of this duty lead to preclusion in review proceedings.

Definition: The obligation to object is the statutory duty of a bidder to object to identified procurement law violations to the contracting authority within certain deadlines in order not to lose the right to subsequent assertion in review proceedings.

What is the Obligation to Object?

The obligation to object is the procurement law counterpart to the civil-law principle of the duty to mitigate damages: anyone who knows of a procurement violation must object to it without delay in order to be able to assert it later in review proceedings. The purpose of the obligation to object is to accelerate the award procedure and enable rapid self-correction by the contracting authority. It prevents bidders from initially deliberately ignoring procurement errors only to use them later, after the award decision is announced, as a strategic means.

Legal Foundations

Germany (§ 160 para. 3 GWB)

The obligation to object is regulated in § 160 para. 3 GWB and, if neglected, leads to the inadmissibility of the review application (preclusion). The following deadlines must be observed:

Identified violations: object within ten calendar days of becoming aware
Violations recognisable from the contract notice: by expiry of the participation or bid deadline
Violations recognisable from the procurement documents: by expiry of the bid deadline

Under § 160 para. 3 sentence 1 No. 4 GWB, violations that only become known at the time of award (e.g. from the bidder notification under § 134 GWB) must be objected to within 15 days of becoming aware. This deadline is rarely applicable in practice.

Austria (BVergG 2018)

Austrian procurement law does not provide for an obligation to object in the German sense. Strict application deadlines apply instead (§§ 321, 328 BVergG 2018) within which applications for review, for issuance of an interim injunction or for a declaration of nullity must be submitted. Allowing these deadlines to lapse results in preclusion of the applicant.

When Does the Deadline Start?

What matters is positive knowledge of the violation, not recognisability. In Germany, the BGH (decision of 26.09.2006 – X ZB 14/06) clarified that the ten-day deadline only begins with actual knowledge of the violation, not already at the time when the bidder could have recognised the violation. The situation is different for violations "recognisable" from the contract notice or procurement documents: here, objective recognisability is decisive.

Consequences of Violation

If a bidder violates the obligation to object, their review application is inadmissible in that respect – the objected violation is no longer examined by the procurement chamber or court (preclusion effect).

However, preclusion does not apply without limits: according to BGH case law, violations resulting from the award itself and only known to the bidder after conclusion of the award procedure are not precluded if the statutory deadline has not yet expired.

FAQ

What counts as "recognisable" within the meaning of the obligation to object? A violation is "recognisable" if an averagely experienced bidder, upon careful reading of the contract notice or procurement documents, would have had to notice the violation – regardless of whether they actually noticed it.

Must I object if I did not receive the contract at all? If the award decision is not yet final and you are violated in your rights, you can object and submit a review application, even if you are not the best bidder.

Does the obligation to object also apply to candidates in the restricted procedure? Yes. Even candidates who are not invited to submit a bid after the participation phase must object to procurement violations in time.
