The tendering procedure allows objections by the losing bidders. However,
"I did not get the order" is not a sufficient reason for objecting.
The losing bidder placing an objection must have good reasons or even
evidence that the order was not granted according to the terms in the
tendering documents. In other words, that the buyer made the decision NOT
based on the (made available to the bidders) criteria.
In this case here, it could be that the losing bidders think that the
chosen product does not fulfill certain mandatory technical requirements
(which their product does), and therefore got more points than deserved in
that particular criterion.
