Restrictive conditions in title deeds must be interpreted by giving the words their ordinary grammatical meaning, viewed holistically in their contextual setting. A court may not excise one part of a restrictive condition and use it to interpret the entire clause. The word 'or' in restrictive conditions is to be construed as disjunctive (meaning 'alternatively') signifying a substitution or alternative, and should only be read as conjunctive (meaning 'and') in exceptional cases where context demands it. Where a restrictive condition provides that land shall revert if it 'ceases to be used' for a specified purpose 'or' is 'no longer required' for such purpose, actual cessation of use constitutes a breach entitling the grantor to reversion, regardless of the owner's stated intention to use the property for that purpose in future. In motion proceedings, a bare or unsubstantiated denial does not create a genuine dispute of fact where the responding party is conversant with the facts and capable of furnishing a proper answer.
