Overview
- The president of the Supreme Court, Edson Fachin, published Resolução 921/2026, which took effect on Friday, Oct. 2, 2026, creating a pre‑validation triage for certain petitions filed inside existing STF cases.
- Under the rule the coordinator of Processing Initial and the secretary‑judiciary will review third‑party or extension requests and the Presidency will decide whether to link them to the original file or open a new case that will be distributed by sorteio or by prevention.
- The resolution covers petitions from people or entities that are not parties, requests to extend a decision’s effects to non‑parties, petitions against non‑parties, and amicus requests that include substantive demands, while excluding ordinary party filings, PGR interventions, internal appeals and high‑secrecy files.
- Fachin framed the change as a response to recent overlapping monocratic provisional orders, including disputes over Nossa Senhora Aparecida posts and a last‑minute bid to include Renan Santos in a TV debate, and it follows a formal request from TSE president Kassio Nunes Marques for a distribution filter.
- The new step aims to protect the judge‑natural principle and reduce contradictory short‑term rulings; it is likely to limit tactics that steer petitions to known relators, alter how urgent election‑related requests reach the Court, and could lead to further institutional coordination or plenary debate if disputes continue.
