Why this matter is tracked

In this employment retaliation case, the court addressed a pro se plaintiff's persistent discovery obstructions and repeated reliance on AI-generated content. The court found that the plaintiff repeatedly cited hallucinated cases and misattributed quotations to existing opinions, despite prior warnings that such conduct would result in sanctions. The magistrate judge struck several of the plaintiff's filings and issued an order to show cause why the case should not be dismissed or other sanctions imposed. The court noted that while it had previously provided the plaintiff with a 'pass' regarding these research failures, the continued pattern of obstruction and reliance on fabricated legal authority necessitated a formal show cause hearing to determine appropriate case-terminating or lesser sanctions.
