This text was written for companies registered in Brazil. Foreign suppliers should also read how foreign companies can bid in Brazilian public tenders.

The session is over, the auction officer (pregoeiro) has declared the winner, and you are sure a mistake was made: the rival bid didn't meet the specification, or yours was disqualified for a reason that doesn't hold up, or the company that was qualified failed to submit a required document. What you do in the next five minutes determines whether you will have any rights afterward.

Because that's the thing: five minutes. You declare your intention to appeal right there, during the session, in a very short window opened by the system. Whoever doesn't declare it loses the right to appeal, even if they are entirely in the right. This guide shows you how not to miss that moment and how to turn the intention into an administrative appeal (recurso administrativo) that actually changes the outcome.

The appeal sequence, in the order it really happens

1. Declaring the intention. Right after the winner is declared, the system opens a field for bidders to record that they intend to appeal. The deadline is usually ten to thirty minutes, as set in the tender notice (edital). Briefly stating the reason is enough — this is not where you argue your case.

2. Submitting the grounds. Once the intention has been declared, a period opens for filing the written appeal, with its grounds. Under the rules of Law 14,133/2021 (Brazil's Public Procurement Law), this period is three business days.

3. Counter-arguments. The other bidders, especially the winner, have the same amount of time to respond (contrarrazões).

4. Decision. The auction officer either reconsiders or forwards the appeal to the higher authority, which decides. If the appeal is granted, the affected acts are annulled and the public tender (licitação) returns to the corresponding phase.

The mistake that kills 90% of appeals

It isn't a weak argument — it's failing to declare the intention. Many people leave the session outraged, look for a lawyer the next day and find out there is nothing more they can do administratively in that tender.

The rule of thumb: when in doubt, declare it. Declaring doesn't oblige you to appeal. If, after a calm analysis, you conclude there was no flaw, you simply don't submit the grounds and the tender moves on. The cost of declaring is zero; the cost of not declaring is losing the right.

That's why you should stay in the session until the end. Leaving after the bidding phase closes, thinking "that's it", is what costs the most opportunities — not least because the qualification (habilitação) phase frequently knocks out the first-place bidder and calls up the second.

What usually gets upheld

Appeals that point to an objective breach of the tender notice have the best chances:

• qualification of a company that failed to submit a required document, or submitted it expired;
• acceptance of a bid whose specification diverges from the terms of reference;
• disqualification of your bid based on a requirement that wasn't in the tender notice;
• disregard of the preference rights of micro and small businesses (ME/EPP) — the tie preference (empate ficto) not being applied;
• failure to observe the minimum publication period;
• acceptance of an unrealistically low bid without first requiring the bidder to prove it is feasible;
• a clerical error in the ranking, such as amounts swapped between bidders.

The common denominator: you show the written rule and the fact that contradicted it. The less interpretation needed, the stronger the appeal.

What rarely succeeds

Generic allegations ("the process was conducted in a biased manner") that don't point to a specific act. Disagreement with a technical judgment that was legitimately exercised — if the tender notice allows samples to be evaluated and the committee evaluated them with stated reasons, disagreeing with the result is rarely enough. Questioning a clause of the tender notice, which should have been done through a challenge to the tender notice (impugnação) within its own deadline, not after the result.

Nor does an appeal succeed when it merely restates the losing bid without pointing to any irregularity. Losing on price is not a flaw.

How to draft the grounds

Four sections, in two to four pages. Objectivity matters more than length.

Identification and timeliness. Company, CNPJ (Brazilian company tax ID), tender notice, case number, session date and a statement that the intention was declared on time. Start by asserting timeliness — it's the first filter in the review.

The facts. Narrate objectively what happened, in chronological order, pointing to the acts of the session. Cite the minutes, the time, the item number. Avoid adjectives: facts persuade, indignation doesn't.

The law. Point to the clause of the tender notice or the legal provision that was breached. Quote the passage and show how it clashes with what was actually done. If there is settled case law from an audit court (tribunal de contas), mention it — but your central argument should be the tender notice's own rule.

The request. Say precisely what you want: "requests that the decision be reversed so that company X is ruled unqualified, and the appellant, ranked second, is called". A vague request produces a vague decision.

Effects: does the tender stop?

The appeal has a suspensive effect on the challenged stage — the award and ratification cannot take place while it is pending. This means the process waits for the decision, which naturally delays the contract.

That power comes with responsibility. A delaying appeal with no basis holds up the purchase of items that are sometimes essential — medicine, school meals, hospital supplies — and wears down your relationship with the agency. Use it when there is a real flaw.

When it's better not to appeal

Not every irregularity is worth fighting. Consider not appealing when: the flaw is minor and wouldn't change the result (you would come third anyway); the contract value doesn't justify the hassle; your own bid had a flaw that would surface under review; or the long-term relationship with that agency is worth more than that particular tender.

This isn't advice to accept illegality — it's recognition that an appeal consumes time and political capital. Pick the battles where winning changes something concrete.

After the administrative decision

If the appeal is denied, two paths remain. The first is a complaint to the competent audit court, which is free and open to anyone, and which can order a precautionary suspension and corrections. The second is going to court, through a writ of mandamus (mandado de segurança) when there is a clear and indisputable right — at this point a lawyer is required and costs go up.

In practice, a complaint to the audit court resolves a good share of cases at low cost, especially when the flaw is evident and documented.

An example of a well-built appeal

Situation: an electronic reverse auction (pregão) to buy laptops. In item 4.2 of the terms of reference, the tender notice requires a processor with a certain minimum performance measured by a public benchmark. The winning company offered a model whose processor, according to the manufacturer's own website, falls below that benchmark. You came second.

The appeal is built like this. In the facts: "at the session of August 12, at 10:42 a.m., company X was declared the winner, with model Y". In the law: item 4.2 is quoted, and the manufacturer's official specification, attached, shows that the model offered does not reach the required benchmark. In the request: "requests the disqualification of company X's bid for breach of item 4.2, with the appellant being called".

Notice what makes this appeal strong: the rule is objective (a minimum benchmark), the evidence is documentary and comes from a neutral source (the manufacturer's website), and the request is specific. There are no adjectives, no assumptions about intentions, no debate about quality — just a demonstration that the written rule was not met.

Compare it with the weak version of the same case: "the winning bid is of inferior quality and harms the public interest". Same situation, same underlying reason — and a very different likely outcome, because it neither points to the clause nor proves the breach.

What to do while the appeal is pending

Three practical steps. Follow the counter-arguments: they often bring up documents you didn't know about, and sometimes reveal that your premise was wrong — in which case withdrawing is the mature decision. Don't stop bidding: the appealed tender may take weeks, and other tender notices for the same item keep coming out. Get ready to perform: if there's a real chance you'll be called, check stock availability and your supplier's lead times, so you don't win the appeal and then fail to deliver.

Deadline table

Counter-arguments: when you are the winner

There are two sides to the coin. If you won and another bidder appealed, you have the same amount of time to submit counter-arguments — and defending your own win requires the same care as attacking someone else's.

The structure mirrors that of the appeal. Start with the preliminary issues: was the appeal filed on time? Was the intention declared within the deadline? Does the appellant have standing? A procedural flaw sinks the appeal before the merits are even considered, and it is the cheapest defense.

On the merits, respond point by point, leaving no allegation unanswered — silence on an argument is read as agreement. Attach proof that your bid complied: catalog, technical data sheet, manufacturer's statement, a certificate valid on the relevant date. And close by asking that the appeal be denied and the decision upheld.

A common mistake among winners: treating counter-arguments as an optional formality. The agency decides based on what is in the case file; if only the appellant has argued, the chance of reversal grows. Responding well takes a few hours and protects the entire contract.

How an appeal affects the contracting timeline

It's worth sizing the impact so you can plan your own cash flow. An appeal adds at least three business days for the grounds, three for the counter-arguments and the review time — which ranges from days to weeks. All told, it is common for ratification to be delayed by two to six weeks.

For those who won and had the result appealed, this means postponing stock purchases and mobilizing staff. Buying before ratification, counting on the win, is an unnecessary risk: if the appeal is granted, you are left with the goods and no contract.

For those who appealed, the math is different: even if you win the appeal, the contract only starts after this whole process. If you needed short-term revenue, you are probably better off focusing your energy on upcoming tenders than on a dispute that will only be settled months later.

Frequently asked questions

Do I need a lawyer to appeal?

Not at the administrative level. The company's legal representative can sign. A lawyer becomes necessary once the matter goes to court.

Will appealing hurt my company in future tenders?

It shouldn't and, in electronic tenders, it's unlikely to — bidding is anonymous until the qualification phase. What damages your standing is repeated appeals with no basis.

Can I appeal a decision ruling my company unqualified?

Yes, and it's one of the most common uses. If you were ruled unqualified over a document you submitted correctly, or over a requirement not set out in the tender notice, an appeal is the way to go.

Can the winner withdraw during the appeal?

It can happen, and in that case the agency calls the next-ranked bidder. That's one more reason to follow the process until ratification, even if you came second.

How long does the decision take?

It varies widely: from a few days to a few weeks, depending on the agency's structure and the complexity of the case. Urgent contracts tend to be decided faster.

Requests for reconsideration and other related tools

Besides the appeal itself, other tools come up in day-to-day practice that sometimes resolve things faster. A request for reconsideration (pedido de reconsideração) is addressed to the same authority that made the decision, is available in specific situations, and is usually useful when the error is obvious and correcting it doesn't require a higher authority.

There is also due diligence (diligência): the committee may, on its own initiative or at someone's request, clarify doubts about a document or bid. Before appealing, a simple request for due diligence is worth trying — in many cases, the auction officer acknowledges the mistake and corrects it during the session itself, with no need for a formal appeal.

Finally, there is a report to the agency's internal audit unit (controle interno), a little-remembered channel that is effective when there are signs of irregular conduct by a public official. It doesn't replace the appeal as far as the tender result is concerned, but it triggers a parallel investigation.

Prepare before you need it

Three habits make a difference when the moment comes. First, follow the entire session, noting times and decisions — the minutes published later don't always include the detail you remember. Second, keep the tender notice and its annexes in their current version, along with any addenda; an appeal is grounded in the written rule. Third, have a ready-made template for the grounds, with the four-section structure, so you don't have to write from scratch under the pressure of three business days.

And remember the essentials: declaring the intention costs nothing and preserves everything. If you follow tenders regularly, check the tenders open right now and block out your calendar so you can stay until the end of every session you bid in. The right to appeal is born and dies in those final minutes.
