Direct answer

What happened in this matter?

The Court issued a formal warning to the pro se plaintiff regarding the citation of non-existent case law.

Why the court cared

Why this matter is tracked

In an order denying a pro se plaintiff's motion for leave to file a supplemental motion for sanctions, the U.S. District Court for the District of Nevada addressed the plaintiff's reliance on non-existent case law. The Court specifically noted that the plaintiff cited 'Graham v. Nyquist' without a reporter or page number, and that the Court was unable to locate the case on Westlaw. The Court cautioned the plaintiff that continued reliance on non-existent or inapplicable case law may result in future sanctions. The order also addressed broader concerns regarding the conduct of both parties, including the use of unprofessional language and the filing of meritless sanctions requests, warning all parties that further vexatious conduct could trigger sanctions under 28 U.S.C. § 1927.
