Argentina: The Supreme Court of the City of Buenos Aires Orders to Reduce the Interest Rate in Labour Lawsuits

The Supreme Court of Justice of the City of Buenos Aires has ordered to reduce the interest rate applicable to labour lawsuits related to accidents in the workplace. On October 1st, 2025, the Supreme Court ruled in the case ‘Provincia Art S.A. about Complaint Regarding Denied Appeal of Unconstitutionality in Boulanger Roberto Eduardo v/Provincia ART about resource law 27.348’ that it is not appropriate to apply the CER index plus capitalization applied by the National Labour Chamber to update credits in workplace accident lawsuits.

The Supreme Court determined the application of the “RIPTE” interest rate, establishing the new update criterion for lawsuits related to workplace accidents in the National Labour Court. This is the first ruling handed down by the Supreme Court of Justice of the City of Buenos Aires as the higher court to the National Labour Appeals Chamber, following the ruling on 27 December 2024 in the case ‘Ferrari, María Alicia v. Levinas, Gabriel Isaías about incident of incompetence’, which enabled the Court to act as the highest court of appeal in cases within the Autonomous City of Buenos Aires.

In conclusion, the Supreme Court overturned the decision of the National Labour Appeals Chamber and determined the application of a lower adjustment index than the one in force, applying instead the RIPTE index in judgements on workplace accidents. In practice, this means that labour courts must apply a new interest rate in labour court proceedings, which results in a lower amount of interest, reducing the cost of  labour lawsuits.
