Rebalancing a Brazilian public contract: the request must be filed before the extension is signed

Under Law No. 14,133/2021, a request to restore the economic and financial balance of a public contract must be filed while the contract is in force and before any extension is signed (article 131, sole paragraph). This deadline did not exist under the previous statute, Law No. 8,666/93. In practice, signing an extension is no longer an administrative formality: it is the last date on which the request can be made.

What the statute requires

Article 124, II, (d) preserves the traditional grounds for restoring the balance: force majeure, fortuitous event, sovereign act (fato do príncipe) and events that are unforeseeable, or foreseeable with incalculable consequences. It adds, however, a condition that did not exist before. Restoration is available only if the objective allocation of risk set out in the contract is respected in every case.

Where the change originates from the government, a different and more favourable rule applies. Article 130 provides that, if a unilateral amendment increases or reduces the contractor's obligations, the balance must be restored in the same amendment, not at a later date.

The risk matrix comes before the merits

Before asking whether the balance was disturbed, one must ask who bore the risk that materialised. Article 22 allows the tender documents to establish a risk allocation matrix, and article 103, paragraph 5, provides that, where the conditions of the contract and of the matrix have been met, the balance is deemed to have been maintained, with both parties waiving claims relating to the risks they assumed. Unilateral amendments by the government and changes in taxes paid directly by the contractor, brought about by subsequent legislation, are carved out.

The consequence is direct. A risk allocated to the contractor that then materialises does not give rise to a right to rebalancing, however expensive it turns out to be. That decision was taken when the bid was priced, not during performance.

How the Federal Court of Accounts has ruled

The Federal Court of Accounts (Tribunal de Contas da União) has held that a contractor who signs an extension without claiming restoration loses the right, by what Brazilian law calls logical preclusion, a form of waiver by conduct. The reasoning is practical: a late request deprives the government of the ability to assess whether that extension was financially advisable. A contractor who extends in silence signals acceptance of the economic terms then in force.

Practical steps

• Treat the contract expiry date as a decision deadline, not merely as a renewal date.
• Read the risk matrix in the tender documents before building the claim. It determines admissibility before any discussion of the merits.
• Support the request with an analytical and documented demonstration of the link between the event and the increase in costs. Generic allegations of price increases are usually rejected, and the review looks at the cost structure as a whole rather than at an isolated item.
• Record a written reservation of rights where the extension cannot be avoided and the claim is not yet ready.

Frequently asked questions

Can rebalancing still be claimed after the extension has been signed?

Article 131, sole paragraph, and the case law of the Federal Court of Accounts point to no. Signing the amendment without a reservation tends to be read as acceptance of the economic terms then in force.

What if the contract has already ended?

Termination of the contract does not in itself prevent recognition of the imbalance. Article 131 provides for compensation through an indemnity instrument. The obstacle is a request made after an extension was signed without reservation.

Does every increase in input costs give rise to a right to rebalancing?

No. If the risk of variation in that input was allocated to the contractor in the risk matrix, article 103, paragraph 5, deems the balance to have been maintained.

Still unsettled

The sole paragraph of article 131 cross-refers to article 107, which governs the extension of continuous services and supplies. Some commentators argue that the rule does not reach fixed-scope contracts with automatic extension, in which case preclusion would not operate. The point is not settled, and the answer varies with the subject matter of the contract.
