This document summarizes several theft case laws related to the concept of appropriation: - Lawrence (1971) established that taking money with consent could still be appropriation. - Eddy v Niman (1971) found no appropriation when goods were placed in a store's trolley as this was consistent with the owner's rights. - McPherson (1973) ruled that placing bottles in a bag showed intent to steal, amounting to appropriation. - Skipp (1975) determined appropriation occurred when goods were loaded and the route changed, not just upon intending to steal. - R v Morris (1983) found appropriation as soon as price labels were switched.
