Gregory J. Van Etten v. Stephanie K. Fattman, et al.

Misrepresented: Legal Norm | Court flagged plaintiff's use of 28 U.S.C. § 636(b)(1)(B) to support the incorrect proposition that a magistrate 'may recommend but cannot strike pleadings absent district-judge adoption,' and corrected that §636(b)(1)(A) and Fed. R. Civ. P. 72 govern magistrate authority over non-dispositive matters. || Misrepresented: Case Law | Plaintiff asserted that the Magistrate Judge's R&R referenced Ankenbrandt v. Richards and Seminole Tribe v. Florida, but the Court noted neither case is cited in the R&Rs the plaintiff relied on. || Fabricated: Other | Court warned generative AI can create incorrect or made-up citations and noted plaintiff's filings contained inaccurate or fabricated citations.
