The resolution rules clearly define the target chamber (Cámara de Diputados) and specify that resolution depends on the party winning the most seats. While initial determination relies on a consensus of credible reporting, discretion is limited by a designated official source, the National Electoral Institute (INE), in case of ambiguity. There are specific tie-breaking mechanisms defined, first looking at total valid votes and subsequently falling back to alphabetical order by party abbreviation. A generous long-stop date of March 31, 2028, allows ample time for election certification and legal challenges before an exceptional timeout resolution to 'Other' triggers.
