Heirs' Preferential Purchase Right Under Lease Agreement

The case concerned a dispute arising from a lease agreement where the tenant's heirs sought to enforce a preferential purchase right stipulated in the original lease, a right the landlord had allegedly violated by selling the property to a third party without offering it to the tenant first. The Court of Cassation overturned the lower court's decision, reasoning that the contractual clause granting the preferential right to the tenant constituted a legally binding obligation on the lessor, and its breach through a direct sale to another party authorized the injured party to seek the nullification of that sale and potentially obtain ownership rights, as the right to preemption was enforceable against subsequent transferees.
