Question juridique clé
Whether the lease/side agreement with Z.________ SA removed the tenant's passive standing and prevented provisional release of opposition.
Solution extraite
The cantonal court's qualification of the arrangement as sublease, not transfer of lease, was not shown to be arbitrary or legally wrong; the tenant remained liable.
Motifs extraits
A written consent clause does not exclude sublease. The appellant's argument based on the landlord's signature did not make the cantonal interpretation untenable.
