Why this matter warrants attention
The court issued an Order to Show Cause requiring defense counsel to explain why Rule 11 sanctions should not be imposed after they submitted a brief containing two non-existent case citations. The court characterized the inclusion of these fabricated authorities as a failure to meet the duty of candor and the duty to ensure filing accuracy.
The court reasoned that defense counsel violated their duty of candor and the duty to ensure the accuracy of filed papers by including non-existent case citations in their response brief, citing ByoPlanet Int'l, LLC v. Johansson and Mata v. Avianca, Inc. as authority for the court's power to sanction such conduct.
