Tenant evicted for subletting; penalty clause deemed unfair and unenforceable due to lack of proportionality.

The court terminated the social housing lease and ordered the tenant to vacate the property for subletting and non-residence. While the tenant was found to be a bad lessee, the specific penalty clause for subletting was declared unfair and unenforceable because it imposed a fixed fine for every minor violation without distinguishing severity. Consequently, the tenant was liable for termination and costs but not for the specific monetary penalty claimed by the landlord.
