What happens if the representative of the signatory is not correctly accredited?
Look, the issue of accrediting well who signs in a public tender is no nonsense. It's like the VIP pass to enter the party: if you don't have it well, you stay at the door and you don't dream of the contract. It looks like a boring formality, but what a mess can be armed if you skip that step. If the representation is not well tied, you can end up seeing how they cancel the award and leave you with a poker face.
Do not be confused: that the guy (or guy) that signs really has the power to do it is key. It is not just about putting a pretty sign, but about demonstrating that he can speak and compromise the company. If you do not do it well, then forget about the business, because the offer can be knocked down and even get out of the contest. And all for a badly presented paper, an expired power, or worse, something false or trucado. There the thing gets ugly.
The law does not go around here. According to the Public Sector Contract Law, if the representation does not block, the administration or thinks about it: it dismisses your offer and you look from outside. And yes, you also lose the guarantee, which is not small, and they can even veto you in future tenders. A disaster, come on.
And be careful, because if the issue already smells like fraud, that is, if you did it on purpose to see if it collapsed, there we already talked about serious legal trouble: administrative, criminal sanctions ... what you want less good. It is not worthwhile to take a joke.
So, companies of the world, here is the free advice: make sure that whoever firm has power and all the papers in order. And if you have doubts, look for a public contract lawyer, to tell you exactly what you need and what risks run. Oh, and don't think that doing it once that's it. If you change the boss, owner, or whatever, check everything again, because what was worth yesterday, the same is no longer useful.
In short, do not play it with this. The well accredited representation is the key. If you lose it, not only do you stay out, but the whole weight of the law falls. And all for not checking some papers. Is it really worth it? I would say no.
