Origin of the case
On March 13, 2014, Banco International filed a collection lawsuit (demanda ejecutiva) against Agrícola Santa Fe Limitada, for the non-payment of a loan in dollars, payable in said currency and documented in a promissory note.
As part of its defense, the defendant invoked that the interest rate determined by the bank exceeded the conventional maximum interest rate in force, whereby requested the Court not to consider said pact and to reduce the interest rate to the common interest rate (tasa de interés corriente) according to the article 8 of Law 18,010 about money lending operations.
