Contractual Non-Performance Justification After Breach Rectification

In a dispute concerning a contractual obligation, the court addressed whether a party could validly refuse performance based on an alleged breach by the other party when that breach was subsequently remedied. The Court of Cassation quashed the lower court's decision, reasoning that once the alleged defaulting party had corrected the failure to perform, the other party could no longer invoke that specific past breach as a justification for their own non-performance, as the basis for the defensive exception had ceased to exist upon rectification.
