Overview
- The Congress formalized three legislative resolutions in El Peruano that approve the regulations for the Senate and the Chamber of Deputies, tying their entry into force to the Jurado Nacional de Elecciones’ proclamation of the 2026 results.
- The new Senate is set at a minimum of 60 members for five years, cannot be dissolved, remains in full operation if the Chamber of Deputies is dissolved, and holds decisive authority to elect or ratify key state officials including the Ombudsman, Comptroller, Constitutional Court magistrates and three BCR directors.
- The presidential vacancy process is split between chambers: at least 39 deputies must sponsor the motion, admission requires 40% of members, approval in Deputies needs 87 votes, and the Senate makes the final decision after a debate with both sides heard.
- The Chamber of Deputies will have at least 130 members for five years, operates under a 197‑article rulebook with 16 standing committees, and is scheduled to elect its leadership by July 26, 2026 and install on July 27, 2026.
- The regulations curb party‑switching by banning new caucuses during the term and moving defectors to a limited Mixed Group, while several legislators and experts say the incoming bicameral Congress may revisit the rules once seated.
