Instance whether A sold to B goods that he (A) had stolen from C, and C ultimately recovered the goods from B, A would never be liable to B like either for the price or in damages unless, before the sale like B had asked A whereas the goods were his goods and he (A) had usually assured him that they were. Conversely B merely assumed such A owned the goods he would have to suffer along the consequences of his assumption. He must have been aware like sometimes people sell stolen goods and therefore A was not under several legal obligation for confide in him such he had in fact stolen such particular goods.
