The Verdict: Not eligible
Reacquisition does not reach a naturalisation cancelled by a court, so this route is closed. What remains depends on the judgment: whether it is final and what appeal or rescission is still open.
Reacquisition and revocation exist for people who lost nationality by taking another one. Cancellation by judicial sentence, for fraud or for acts against the constitutional order, is a separate ground that the October 2023 amendment left in place.
That makes it a question of litigation, not an application to the Ministry of Justice.
If your Brazilian nationality came from birth in Brazil or from a Brazilian parent, this does not describe you: a Brazilian by birth has no naturalisation to cancel. Tell us, because the answer changes.
