Slippery Sam steals a car from John and then sells it to Franky for $4,000. Slippery Sam runs away, but John finds out that Franky has the car. John claims that Franky has to give it back.

(a) Explain the law that is relevant in deciding whether John or Franky is the owner.

(b) Would it be different if Slippery Sam didnt steal the car, but rather paid for it using a cheque that was not honoured by the bank?
