Wow, this would be quite a black eye for someone whose role is to be an expert on this stuff. I'm sorta shocked by people still getting caught in this quagmire. I mean, I was surprised by the lawyer who stepped in it by submitting bogus case law last year or whenever that happened, but it had to happen at least once or a few times for there to be a "see what happens" moment to make people aware.
But this would be truly damaging, a sure sign that said expert lacks credibility and self-awareness.
