This NSW Court of Appeal case demonstrates the significance of Lessors making specific and reasonable requests for information when a Lessee seeks consent to assignment of a Lease as well as the requirement to deal expeditiously with a request. Furthermore, the case considers the requirement to provide a disclosure statement when the assignee is already a party to the lease.
