Seller Sally is selling some ostensibly old and rare CDs containing music by a famous band. She claims that the record label supplied them to her directly for promotion when she was working for a radio station decades ago.
These particular CDs are unknown of among collectors: verifying their authenticity is difficult.
Buyer Bob trusts Sally's story and buys the CDs.
Several years later Bob obtains very compelling evidence that the CDs are in fact counterfeit: the record label never produced them.
What legal recourse does Bob have, and for how long? Is there anything Bob can do when buying the CDs from Sally to lock her into some liability so that Sally is deincentivised from selling them in case she is lying?
