Bid protests before FAS Russia under laws 44-FZ and 223-FZ, November 2025 to October 2026: decisions and effect on procurement procedures (anonymised dataset, snapshot 2026-10-13)

Anonymised dataset of decisions by FAS Russia (the Federal Antimonopoly Service) on complaints against public procurement procedures under laws 44-FZ and 223-FZ. It covers procedures with bid deadlines from 5 November 2025 to 8 October 2026 (snapshot of 13 October 2026) and contains 728 records, each one procurement procedure against which a complaint was filed and decided.

All four outcomes are included (upheld 48, partially upheld 145, dismissed 436, refused consideration 99), so success rates can be computed by region, type of contracting authority and procurement category. Complaints were upheld in full or in part in 26.5 per cent of all decisions and in 30.7 per cent of the complaints considered on the merits; 104 upheld complaints led to the annulment of protocols or the cancellation of the procurement. Fields cover the law, the procurement method, a generalised category of the procurement subject, the initial contract price, the electronic trading platform, the generalised legal form and level of the contracting authority, the region and federal district, the FAS office, the bid deadline, the outcome of the complaint, its effect on the procedure and the result of any appeal to the central office of FAS.

This dataset replaces and extends the dataset of 1 September 2026 (https://doi.org/10.5281/zenodo.22236602). It covers a longer period, draws on a wider set of the publisher's case registries, adds decisions issued after 1 September 2026 and updates the outcomes of earlier cases. The field structure is unchanged; values were added to three fields.

Information identifying the complainants, the texts of FAS decisions and the publisher's internal case management have been removed; names of contracting authorities and procurement subjects are generalised; procurement registry numbers are not published. The dataset contains no personal data. The data reflect complaints filed by a group of external market participants that monitor procurement, not all complaints received by FAS Russia; distributions and success rates should be read within that set. For 107 records the source registry does not record the initial contract price.

The package contains the data as CSV and JSON, a Frictionless datapackage.json with schema and checksums, a README with field descriptions, codebook, method, limitations and summary statistics, and the scripts used to produce the dataset (anonymize.py, translate.py, make_package.py).
