Landlord v. Tenant: Unauthorized Sublease Violation Leading to Eviction

A tenant, having subleased a property without the landlord's written authorization as required by the lease, was sued for eviction and damages following the subtenant's failure to pay rent. The Court of Cassation upheld the eviction, reasoning that the breach of the specific contractual clause prohibiting subleasing without written consent constituted a serious ground for termination of the main lease, irrespective of whether the subtenant was ultimately at fault for the non-payment or if the landlord had tolerated the subletting previously, as the lack of formal written authorization was an insurmountable contractual violation.
