Letting an unsigned bid be regularized after the deadline: the Council of State suspends the award to the lowest bidder in Antwerp
The city of Antwerp wanted to admit the lowest bidder, Beneens en Zonen, to the negotiations and let it regularize its unsigned bid by resubmitting it via e-Tendering after the submission date; on the application of the second-lowest bidder, Pit Antwerpen, the Council of State suspended that decision as contrary to the specifications and to the equal treatment of bidders.
What happened?
Acting as a joint purchasing centre (together with the Antwerp public welfare centre), the city of Antwerp launched a public works contract for fire-safety and acoustic adaptation works at 'Het Oude Badhuis' (specifications no. GAC/2013/1984 (PO/14780181)). It chose the simplified negotiated procedure with publication and announced the contract in the Bulletin of Tenders of 20 August 2013. The specifications required submission via e-Tendering, and the annexed manual expressly stated that an unsigned bid cannot be retained and that the bid must be signed by the authorised representative. The final submission date was postponed to 3 October 2013 at 10:15. Six bidders submitted in time (VAT excluded): Beneens en Zonen bvba at 467,523.59 euros, Pit Antwerpen nv at 477,256.56 euros, GS Bouw bvba at 497,691.79 euros, Renovatiebouw Van Broeckhoven nv at 499,898.20 euros, Fr. Goedleven nv at 543,647.93 euros and Buyse bvba at 598,431.65 euros. The opening record, however, noted for Beneens en Zonen that 'no signed submission reports were found': its bid stated neither a signatory nor a signature method. The record also showed that this bidder, on 3 October 2013 between 10:09:35 and 10:13:16, had withdrawn eight previously submitted documents and, at 10:13:58, submitted a single new 'inschrijving.zip'. On 25 October 2013 the college decided to admit Beneens en Zonen to the negotiations and to let it 'regularize the signature on the bid' — in practice by resubmitting the bid electronically via e-Tendering — subject to a fifteen-calendar-day standstill. The city relied on the a contrario reasoning that article 51 of the Placement Royal Decree does apply to the negotiated procedure with publication, but that the absence of a signature in negotiated procedures does not automatically render the bid substantially irregular. Pit Antwerpen, the second-lowest bidder, sought suspension under extreme urgency. Because the Act of 17 June 2013 applied, no proof of serious harm difficult to repair was required for the suspension, and the Council only had to examine whether serious pleas were raised. The Council of State held that, through the 'regularization', the city had in essence admitted to the negotiations a candidate who — for lack of any signature — had not yet committed at all, while at that point there was no signed bid, and thus no commitment, and it could not be verified whether the bid remained substantively unchanged. If it were the same bid, its submission took place after the date set in the specifications, contrary to the clause that late bids are not taken into account. That appeared contrary to the specifications and to the equal treatment of bidders, all the more so since the other bidders had already committed by their timely submission whereas Beneens en Zonen alone would get the chance to commit only later. The Council recalled that, under settled case law, signature is a substantial formal requirement touching on equality between bidders, and that even in the relatively form-free negotiated procedure an authority remains bound by its own specifications and by the equality principle. The single plea was serious, and the Council ordered the suspension under extreme urgency of the contested decision.
Why does this matter?
The judgment draws a sharp line around what 'regularizing' may mean. The flexibility of a negotiated procedure lies in the award phase — negotiating price and terms — and not in whether a bid was submitted in time and validly. A signature is not a formality for form's sake: it embodies the bidder's commitment, and letting it be added later by resubmitting the bid after the deadline gives one bidder the chance to commit only once it can already assess its chances of success. That affects equality with the others, who had already committed irrevocably at the opening. For authorities, the lesson is that opting for a negotiated procedure does not release them from their own specifications: an authority that itself writes that an unsigned bid will not be retained cannot set that rule aside afterwards for the lowest bidder. For bidders, the judgment shows that the suspension threshold in procurement is low — no proof of serious harm required — and that a breach of equality is a strong ground for suspension.
The lesson
If you are an authority, your own specifications bind you: if they require bids to be submitted via e-Tendering and signed and that late bids are not retained, you cannot let an unsigned bid be 'regularized' after the deadline by having it resubmitted. Choosing a negotiated procedure does not change this: its flexibility concerns the negotiating, not the valid and timely submission. Signature is a substantial formal requirement touching on equality, because it embodies the bidder's commitment. If you are a bidder, remember two things. Make sure your bid is signed in time and correctly — test your electronic signature early. And if a competitor misses a valid signature yet the authority gives it a second chance, do not hesitate: in procurement you need not prove serious harm difficult to repair for a suspension, and a breach of equality carries weight.
Ask yourself
Was the bid validly signed by the authorised representative at submission, or only afterwards? Are you letting a missing signature be 'regularized' by having the bid resubmitted after the submission date? Then you are probably breaching your own specifications and the equality principle. Do you realise that the flexibility of a negotiated procedure concerns the award phase and not the valid, timely submission of the bid? Are you giving one bidder the chance to commit later than the others, who had already committed at the opening? Do you know that, to suspend an award decision, you need not show serious harm difficult to repair (Act of 17 June 2013)?
