The document discusses several court cases related to the definition of theft and appropriation. It notes that in some cases such as Lawrence (1971), taking property with consent was still considered appropriation. However, in other cases such as Fritschy (1985) and Gallasso (1993), taking property with the owner's permission did not amount to appropriation in the legal sense of theft. The document analyzes how the legal concept of appropriation has been applied inconsistently depending on the specific case and jurisdiction.
