“reserves the right to alter its determination of authenticity based on the review of new information.” The company continues to remove itself from “any guarantees, warranties, or representations” in regards to the item’s “genuineness, authorship, attribution, provenance, period, culture, source, origin, or condition.” The fine print ends with a further withdrawal of its accountability: “the customer hereby releases CGA from all liability and damages whatsoever, whether actual or consequential, arising out of or related to the issuance of this certificate.”
This careful wording makes it clear that they will not be held legally or financially responsible for any wrong certifications or for negligence on its part. The piece of paper comes without an obligation to reimburse the owner, partially or fully, should the item turn out to be not as advertised.
