Question juridique clé
Whether the lease termination of 13 February 2008 was valid despite the protection period and alleged personal need.
Solution extraite
The termination was annulable because it was given during the protection period and the asserted personal need was not established at the relevant time.
Motifs extraits
The cantonal court's factual findings bound the Federal Court: the notice was given to enable demolition and new construction, not for personal occupation. The landlords bore the burden of proving an exception to the protected-period rule, but the personal-need ground was raised too late and remained doubtful. A later or different justification cannot retroactively validate a protected-period termination.
