Minutes of the Argentine Submarine Force Advisory Council signed by fourteen navy captains on 30 April 2017, seven months before the implosion of the ARA San Juan in the South Atlantic, have become central evidence in the ongoing oral trial before the Federal Oral Court of Santa Cruz, based in Río Gallegos. The document, cited by the Argentine outlet Infobae, details the technical issues outstanding and the operational restrictions affecting the submarine before its final mission, and constitutes one of the central elements of the debate over the eventual criminal responsibility of the four former senior naval commanders charged in the case.
