A more thorough explanation: A “bad passport” typically refers to a passport that has been reported lost or stolen, or one that has been revoked or invalidated by the issuing authority. It may also refer to a passport that contains false information or has been altered in some way. In legal terms, a bad passport is one that is not valid for travel or identification purposes due to these reasons.
Example: The traveler was denied entry into the country due to possessing a bad passport that had expired.
