What the court wrote

Verbatim from the court's document (public domain). Ellipses mark omitted text; nothing is paraphrased.

Brooks Farms, LLC, 624 S. W. 3d 601 (Tenn. Ct. App. 2020). ” (See Doc. 31, at 3 n. 1; Doc. 35, at 4. ) Plaintiffs have filed a notice of errata acknowledging some of these errors. (Doc. 36. ) The Court does not find it necessary to address sanctions at this time, but Plaintiffs are reminded that Federal Rule of Civil Procedure 11 applies to pro se litigants and that citation to non-existent authority undermines the credibility of otherwise legitimate arguments. The Court encourages Plaintiffs, should they seek legal counsel in any future proceedings, to ensure that any legal citations are carefully verified. PageID #: 330
