Once the negotiation or dialogue has ended, tenders that remain irregular or unacceptable are eliminated.

In all procedures, the purchaser may authorise all tenderers concerned to regularise irregular tenders within an appropriate period, provided that they are not abnormally low.The regularisation of irregular tenders may not have the effect of altering their substantial characteristics.
