Oldham Metropolitan Borough Council v Tanna  EWCA Civ 50
This is a planning case, but it may well be of interest to those dealing with the Service of Notice.
Ordinarily the address for service of notice, certainly, for 1993 Act matters, is the address shown on the service charge or ground rent demand in accordance with sections 47 and 48 of the Landlord and Tenant Act 1987.
Different considerations apply if the landlord is ‘missing.’
However what Tanna seems to be saying is that, (for planning cases certainly) that service on the registered proprietor’s address as shown at the land registry will be sufficient.
