In the case "Benítez Quiroga, Ricardo A. v. Mapfre Argentina ART SA - Salary differences", the Labor Court of Appeals N. III recently issued a ruling opposing to the unanimous criterion coming from the famous case "Tulosai", and decided to include the 13th salary in the base for estimating the severance for dismissal. The abovementioned Court based its decision on Ley 26.853 that recently ordered the creation of Cassation Courts and annulled the obligation of ruling according to previous doctrine that was mandatory for judges of first and second instance up to the moment.
