Overview

• The National Electoral Chamber ruled on Oct. 13 that reprinting the paper ballot for Buenos Aires is materially impossible, so the Oct. 26 election will use ballots that show José Luis Espert for La Libertad Avanza.
• In a separate file, the court confirmed Diego Santilli as the legal first candidate on the list, decoupling the printed image from the formal order of candidates.
• Technical reports set Oct. 16 to begin distribution and estimated at least five days to reprint, meaning the practical cutoff passed on Oct. 10 and the appeal reached the chamber on Oct. 11.
• The Buenos Aires electoral board, Judge Alejo Ramos Padilla, and federal prosecutor Ramiro González had already opposed the request, warning about risks to the election and the need for legal certainty.
• Authorities cited scale and cost constraints—about 14–15 million ballots for 38,760 tables and an Interior Ministry estimate near 12,169 million pesos—while considering lower-cost mitigations such as updated posters at polling places.
