Lessor v. Lessee (Exclusivity Clause in Lease)

A lessor sought termination of a lease agreement and eviction of the lessee based on the lessee's failure to fulfill a clause requiring the premises to be used exclusively for the practice of a specific profession, alleging the lessee was also operating a business of selling related materials, which constituted a breach of the lease terms. The Court of Cassation rejected the appeal, finding that the lower court reasonably determined, based on the evidence presented, that the alleged secondary activity of selling materials was merely accessory to the primary professional activity and thus did not constitute a breach of the exclusivity clause stipulated in the lease agreement.
