You let the framework agreement pass at the time — you can't later hijack a joining decision to kill the whole agreement
The Council of State recognises that a municipality's decision to join an existing framework agreement of a purchasing body is separately reviewable by a competitor — but dismisses the request because the competitor let the original framework agreement go uncontested, and the principle of legal certainty bars incidental challenge.
What happened?
The saga begins in September 2024, when the ASBL Opdrachtencentrale (a purchasing body) tenders a framework agreement for the production and delivery of electronic meal vouchers for its affiliated members. Two operators are selected: Pluxee and Monizze. Only Monizze submits an offer — Pluxee drops out without filing any objection ('for commercial reasons'). On 9 January 2025 the framework agreement is awarded to Monizze and published on 30 January 2025. Pluxee files no appeal. In June 2025 the city of Charleroi launches its own open procedure for meal vouchers (over 11 million euros over several years). Three bidders: Pluxee, Monizze, Edenred. On 16 December 2025 the contract is awarded to Edenred; Pluxee files for urgent suspension. On 20 January 2026 Charleroi takes two decisions: (i) it withdraws the Edenred award and closes its own procedure (Pluxee's related suspension action is dismissed by ruling 265,834 of 25 February 2026); (ii) it decides to join the Opdrachtencentrale framework agreement through a commande to Monizze running until 22 January 2031 for an estimated 11,613,000 euros. Pluxee files for urgent suspension of this second decision. The Council of State works through the knots systematically. Jurisdiction: Charleroi is an administrative authority. Applicability of the 17 June 2013 Remedies Act: the decision to rely on a purchasing body's framework agreement is itself a decision of a contracting authority (article 47, §2 of the 17 June 2016 Act). Standing: Pluxee did submit an offer in Charleroi's own open procedure, and that suffices — it is irrelevant that Pluxee had chosen not to bid in the original framework agreement. First plea: the purchasing body is not a contracting authority. Rejected. The ASBL meets, prima facie, the cumulative criteria of article 2, 1°, c) of the 17 June 2016 Act: it has legal personality, it was created for a need of general interest of a non-industrial/commercial character, it is not-for-profit and not in competition, and its bylaws ensure that more than half of its directors are designated by contracting authorities. Pluxee's suggestion that non-authority members could in theory join was not supported by evidence of actual dilution. Second plea: the underlying framework agreement is itself illegal (overly broad list of beneficiaries, no date of joining specified), and Charleroi was not 'clearly identified'. Two prongs. First prong — the legality of the original framework agreement. Rejected categorically: Pluxee did not challenge that framework agreement within the 15-day deadline of article 23 of the 17 June 2013 Act. Three reasons now bar incidental challenge: (i) the ASBL is not an administrative authority, so no direct Council of State jurisdiction applies to its decisions; (ii) its acts are not administrative acts reviewable under article 159 of the Constitution; (iii) the principle of legal certainty — now reinforced by CJEU 29 April 2025, Fastened Deutschland, C-452/23 — prevents reopening definitive procurement decisions via later incidental claims. Second prong — was Charleroi 'clearly identified' as a beneficiary? Annex E of the framework agreement's specifications lists 'the municipalities of the Walloon Region'. Charleroi is such a municipality. Recital 60 of Directive 2014/24/EU specifically allows identification by category in a clearly delimited geographic zone. Plea on this point also rejected on the merits. Application dismissed, Pluxee ordered to pay costs (200 + 26 + 770 euros), each intervener bears its 150-euro intervention fee.
Why does this matter?
Central purchasing bodies are everywhere in the Belgian public sector — from federal FORCMS to local ASBLs like the Opdrachtencentrale. For competitors the timing of appeal strategy is critical: anyone who realises too late that a framework agreement will lock up a major market segment cannot later kill it through the back door by attacking a joining decision of a participant. For contracting authorities joining a framework agreement this ruling is reassuring: if you fall within a clearly identified category (e.g. 'municipalities of the Walloon Region') you can safely join without fear of suspension on identification grounds. At the same time it confirms that the joining decision is itself reviewable — authorities must therefore document that they fall within the scope of the framework agreement and that the purchasing body is genuinely a contracting authority.
The lesson
For market players: a framework agreement must be challenged at the moment of its award — no later than 15 days after knowing the award decision under article 23 of the 17 June 2013 Act. Those who let that deadline pass cannot later use appeals against joining decisions of participating authorities to incidentally question that framework agreement's legality. The only grounds that remain available against a joining decision are its own: does the authority fall within the identified category of beneficiaries? Is the purchasing body genuinely a contracting authority? For contracting authorities: before you join, check (i) that you fall within the explicit beneficiary category in the framework agreement's specifications, and (ii) that you hold legal certainty that the purchasing body meets all the criteria of article 2, 1°, c) of the 17 June 2016 Act — preferably with a prior legal opinion filed in the administrative file.
Ask yourself
For market players: when a framework agreement is published that you suspect many authorities will later use — did you consider an appeal within 15 days of the award, even if you were not immediately harmed? For contracting authorities: does your joining decision file contain a prior legal opinion (from regional authorities, in-house counsel or external) on the purchasing body's status, and does your decision explicitly state which category of the beneficiary annex you belong to?
