“… The “dirty secret” of the insurance industry is that most denials can be successfully appealed…”
Usually when signing things off like this, it’s affirming that you believe all statements to be true. They would have to prove you willingly lied, not that you were simply wrong, which is very difficult to prove legally.
That said, IANAL.
‘Reckless disregard for the truth’ shows up sometimes, especially in e.g. defamation.
If the AI cites some legal case from 2015 or a random medical article, you probably need to ensure that those articles actually exist, and not simply assume that the AI is right.
If the AI said that a month’s supply of Fentanyl is the recommended treatment for a headache, no reasonable person is going to believe it. That means that if you say that you believe that, the court isn’t going to consider you a reasonable person.
IANAL either.
