Michele Cassata and Ross Cassata v. Michael Macrina Architect, P.C.

Summary

The Supreme Court, Suffolk County, addresses sanctions arising from defense counsel’s submission of motion papers containing nonexistent or inaccurate case citations and quotations, unsupported legal propositions, and unattributed copying. The court analyzes counsel’s duties under New York’s sanctions rules and Rules of Professional Conduct, including competence, diligence, supervision, and technological competence in connection with artificial intelligence. The underlying action concerns alleged negligent architectural design, professional malpractice, and breach of contract following the collapse of a house under construction.

Holdings

1. Submitting nonexistent decisions or quotations, misrepresenting the holdings of cited cases, and advancing unsupported legal propositions constitutes frivolous, unethical, and sanctionable conduct, regardless of whether the inaccuracies resulted from artificial intelligence or copying from another brief.
2. Counsel and the law firm violated Rules 1.1, 1.3, and 3.3 by filing opposition papers containing unverified authorities, unsupported propositions, and copied material without adequately investigating, tailoring, or promptly correcting the submission.
3. The supervising attorney and law firm violated Rule 5.1 by failing to adequately supervise the drafting attorney, failing to maintain sufficient safeguards concerning AI-enhanced research and copied briefs, and failing to take reasonable remedial action after the inaccuracies were discovered.
4. The court rejected defendant's request to withdraw and redo the opposition because allowing corrective filing without sanctions would leave the opposing party without a remedy for wasted resources and would fail to protect the integrity of the judicial process.
5. Appropriate sanctions included striking the opposition, requiring the drafting attorney to file and serve the sanctions decision, imposing a $1,000 fine on the drafting attorney and a $1,000 fine on the supervising attorney, and requiring the law firm to pay $8,000 in reasonable attorneys' fees, costs, and expenses to plaintiffs' counsel.

Questions Presented

1. Whether defense counsel's submission of nonexistent case citations and quotations, unsupported legal propositions, and unverified copied material constituted frivolous and sanctionable conduct.
2. Whether the conduct violated the New York Rules of Professional Conduct concerning competence, technological competence, diligence, frivolous claims and contentions, candor to the tribunal, and supervision.
3. Whether the supervising attorney and law firm were responsible for inadequate supervision and failure to take reasonable remedial action.
4. Whether defendant should be permitted to withdraw and redo the offending opposition rather than face sanctions.
5. What sanctions were appropriate and proportionate under 22 NYCRR 130-1.1 and the court's inherent authority.
