Overview
- Judges Mariano Borinsky and Gustavo Hornos formed the majority to uphold Santa Cruz as the trial venue, while Javier Carbajo dissented in favor of Mar del Plata.
- The majority cited the high‑seas location, uncertainty over the crime scene, and the fact the submarine never reached port, applying a subsidiarity rule to retain the original court.
- Technical reports placing the implosion south of the Chubut–Santa Cruz boundary supported the jurisdiction of Caleta Olivia and the Río Gallegos tribunal.
- Requests to move the case to Mar del Plata or Buenos Aires came from some families, defense teams, and prior prosecutorial opinions, whereas the Public Defender and attorney Valeria Carreras urged keeping it in Santa Cruz.
- The decision clears a key hurdle for the oral trial of Luis Enrique López Mazzeo, Claudio Villamide, Héctor Alonso, and Hugo Miguel Correa, who face charges including breach of duty and aggravated negligent disaster resulting in death.
