Argentina appeals court annuls part of corruption case against ex-partner of Martín Menem

Argentina's Federal Chamber (Sala II) annulled part of the case against Martín Aguirre, former business partner of presidential chief of staff Martín Menem, over contracts with state health insurer Osprera. The court questioned the investigation's progress and ordered justification of asset seizures, following testimony by defendants. This is a legal setback for prosecutors, potentially weakening the broader corruption probe.
