"Speedwell Estates Ltd and another v Dalziel and others" CA, 31 July 2001, examined whether the failure to provide required particulars under the Leasehold Reform Act 1967 sched 3 para 6 was an 'inaccuracy' not an invalidation of the notice of claim issued by each tenant (D). D had sought to acquire the freehold of their respective houses but the notices failed to contain particulars specified by the 1967 Act, including the dates of the respective leases, incorrect names of the parties, rateable values of the houses and no information regarding financial limits and the relevant valuation provision of the act. The landlords (S) contended that these invalidated the notices. The county court judge accepted the S's contentions and D appealed. CA dismissed the appeal; the failure to provide the correct details of the relevant leases or the details of the rateable values would not have invalidated the notices but the failure to provide details of the periods of residential occupation, the financial information and the relevant valuation provision did invalidate the notices.
