Questione giuridica chiave
Whether the owners had an actual and practical interest to challenge the building's assujettissement to the LDTR after obtaining relief on the renovation issue
Decisione estratta
They lacked a current, practical, legally protected interest to seek review of the assujettissement question.
Motivazione estratta
The impugned assujettissement only affected them eventually; they had already prevailed on the need for authorization for the studio works, and any future similar works could be litigated later if a transformation decision were issued.
