The Possibilities and Limits of Section 46 of the Public Procurement Act in Light of Evaluable Data
4/20/2026

Partner Karel Masopust has published an article titled “The Possibilities and Limits of Section 46 of the Public Procurement Act with Regard to Evaluable Data” in the latest issue of the professional journal Public Procurement.
The text addresses an issue that may at first glance appear to be a procedural detail, but in practice has a significant impact on the course of procurement proceedings. Section 46 of the Public Procurement Act serves as a tool aimed at mitigating excessive formalism and enabling the correction of deficiencies in bids without automatically resulting in the exclusion of a contractor.
However, the key problem remains defining the line between permissible clarification of a bid and its impermissible modification. The article emphasizes, in particular, the need to distinguish between situations where clarification merely removes formal ambiguities and cases where it could already lead to a de facto change in the content of the bid. It is essential that the data subject to evaluation be objectively fixed as of the deadline for submitting bids.
Conversely, an impermissible change occurs if the contractor were allowed to modify or optimize the parameters of the bid after the fact, respond to competing bids, or subsequently choose between options within an originally ambiguous bid.
The article also addresses the broader context of the application of Section 46 of the Public Procurement Act, particularly the question of whether this provision constitutes merely a right of the contracting authority or whether, under certain circumstances, it may become an obligation. Case law does not provide a completely uniform answer to this question. The full text of the article is available in the current issue of the journal.
