Lease Validity Based on Mutual Intent Over Formal Defects

The case involved a dispute concerning the validity of a lease agreement executed between a lessor and a lessee, where the lessor later claimed the agreement was null due to a perceived defect or omission in the contractual terms regarding a certain right or obligation. The appellate court upheld the validity of the lease, finding that the alleged defect did not constitute a ground for nullity because the common intent of the parties, as demonstrated by the execution and subsequent performance of the contract, clearly indicated their mutual understanding and agreement on the essential terms, leading the high court to reject the appeal and affirm the lower court's decision based on the principle of interpreting contracts according to the actual will of the parties rather than strictly formal deficiencies.
