Ex-Ante Transparency Notice in Public Procurement Law

The ex-ante transparency notice is a voluntary advance publication prior to contract conclusion without EU-wide tender that prevents the contract from being declared ineffective. § 135 GWB, § 139 BVergG 2018.

Definition: The ex-ante transparency notice is a publication that a public contracting authority issues voluntarily in the Official Journal of the European Union, announcing the intention to conclude a contract without prior EU-wide tendering. Combined with a standstill period of at least 30 days, it excludes the ineffectiveness of the subsequently concluded contract pursuant to Art. 2d(4) Directive 89/665/EEC, § 135(3) GWB and § 139 BVergG 2018.

What is the ex-ante transparency notice?

The ex-ante transparency notice is a procurement-law protective mechanism that allows public contracting authorities to conclude a contract without a prior EU-wide tender, without that contract later being declared ineffective, provided certain transparency requirements are met. The term is derived from the Latin "ex ante" (= in advance) and refers to the chronological sequence: the notice is published before the contract is concluded.

The instrument was introduced by Directive 2007/66/EC (Remedies Directive II) in Art. 2d(4) of Directive 89/665/EEC and is implemented in Germany in § 135(3) GWB and in Austria in § 139 BVergG 2018.

Significance and function

The ex-ante transparency notice is the central instrument for avoiding the ineffectiveness consequence of § 135(1) GWB or § 334 BVergG 2018 when a contracting authority wishes to award a contract without an EU-wide notice.

Typical use cases

In-house awards – Awards to affiliated entities where the contracting authority takes the view that the Teckal criteria are met, but legal uncertainty remains
Inter-municipal cooperation – Awards based on cooperation agreements between public contracting authorities
Negotiated procedure without prior publication – Cases in which the contracting authority considers the conditions for a negotiated procedure without prior publication to be met, but the legal position is not clear-cut

Requirements and procedure

To obtain protection from ineffectiveness, the contracting authority must observe the following steps:

Publication – The notice must be published in the Official Journal of the EU (TED/SIMAP) and must state the intention to conclude the contract and the justification for foregoing an EU-wide tender
Standstill period – Following publication, a standstill period of at least 30 calendar days must be observed before the contract may be concluded
No contract conclusion before expiry – If the contract is concluded within the 30-day standstill period, the protection from ineffectiveness does not apply

Legal effect: exclusion of the ineffectiveness sanction

Where the requirements are met, the concluded contract can no longer be declared ineffective on the grounds of a missing notice (§ 135(3) GWB, § 139 BVergG 2018). The review body may in this case, as an alternative sanction, impose a fine on the contracting authority or shorten the term of the contract.

Relationship to ineffectiveness

The ex-ante transparency notice only protects against the ineffectiveness sanction on the grounds of a missing notice. It does not cure other procurement-law breaches and does not release the contracting authority from its obligation to design the contract lawfully in substantive terms.

FAQ

Does the ex-ante transparency notice prevent any kind of review? No. The notice only excludes the ineffectiveness sanction under § 135(1) GWB (missing notice). A review application is still possible; the review body may, as an alternative, impose a fine or shorten the contract term.

What information must the ex-ante transparency notice contain? At a minimum, the notice must contain the identity of the contracting authority, the subject of the contract, the justification for foregoing an EU-wide tender, and the intention to conclude the contract. The standard forms of Implementing Regulation (EU) 2019/1780 must be used.

When does the 30-day period begin? The 30-day standstill period begins on the day the notice is published in the Official Journal of the EU. The contract may not be concluded before this period expires.
