Why this matter warrants attention
The Court issued a formal warning to the pro se plaintiff after he cited a non-existent case, 'Abbott v. Washington County.' The Court explicitly cautioned that future inclusion of fabricated or non-existent legal authority in filings would justify sanctions, including potential monetary penalties, striking of briefs, or dismissal of the case.
The Court reasoned that the plaintiff's citation was non-existent and did not correspond to the provided volume or page numbers in the Oregon Reports. It further noted that the cited case had no relevance to the legal issues presented, and that the plaintiff's reliance on fabricated authority warranted a warning regarding potential future sanctions.
Pro-se fabricated citations trigger warnings now; expect sanctions on the next filing.
