Ha! Interesting question. I just ran an all state&#x2F;federal Westlaw search for &quot;IANAL&quot; and didn&#x27;t hit any case law. Two or three briefs, a couple of scholarly articles, but no court opinions. I also searched for &quot;I am not a lawyer&quot;, but that brought up about 130 caselaw hits which seemed to primarily be references to various filings by pro se parties actually saying in a court filing &quot;I am not a lawyer&quot;.
