Sale Rescission Proportionality to Breach

The case concerned a dispute arising from the execution of a contract for the sale of a building, where the seller later claimed the buyer had not fulfilled their contractual obligations regarding payment or delivery of a required guarantee, leading to a court order for rescission of the sale and damages. The high court ruled that the lower court erred by strictly applying a contractual clause making immediate rescission possible upon simple notice of non-performance without considering whether the non-performance was sufficiently grave to warrant such a severe sanction, as the rescission must be proportional to the breach, thereby quashing the lower court's decision.
