What happened in this matter?
The court sanctioned defense counsel for submitting briefs containing hallucinated case law and fabricated quotes generated via VLex Fastcase.

- Why the court cared

P. 11.02 and Minn. Stat. § 549.211. The court found that the attorney failed to perform reasonable inquiry, noting that the citations were easily verifiable as fake, and concluded that sanctions were necessary to deter future misconduct and maintain the integrity of the judicial system.
