Why this matter warrants attention
The arbitrator issued a formal warning to the employer's counsel for submitting four fabricated legal citations. The tribunal concluded that the counsel's failure to verify the existence of the cited cases constituted a serious breach of professional duty, though it declined to impose additional monetary sanctions beyond the public reprimand in the award.
