A more thorough explanation:

JUS VINDICANDI

Jus vindicandi is a legal term from Roman law that refers to an owner's right to recover lost possession, even from someone who bought the item in good faith. This right is not recognized in modern law, but there were some exceptions.

For example, if someone stole your car and sold it to an innocent buyer, you would have the right to take back your car from the buyer under jus vindicandi. Another example would be if someone found your lost watch and sold it to someone else, you could still claim it back from the buyer.

These examples illustrate how jus vindicandi allowed owners to reclaim their property, even if it was in the hands of someone who had bought it in good faith. This was an important right in Roman law, but it is not recognized in modern legal systems.
