Background

Amanda Sima retained Benesch and attorney Justin Barker in 2022 for a limited engagement to investigate claims and negotiate with Novolex over an allegedly copied spill-proof cup lid and related marketing materials. While representing Sima, Barker was negotiating a move to Nelson Mullins, Novolex’s outside counsel. Benesch terminated the representation in April 2023, citing Sima’s unpaid fees; Barker soon became a Nelson Mullins partner.

Sima alleged that Barker’s conflict and withdrawal left her unable to pursue viable claims against Novolex before limitations periods expired. She also sought recovery of her $20,000 retainer, emotional-distress damages, and punitive damages. The Northern District of Illinois dismissed her second amended complaint with prejudice for failure to state a claim.

The Court’s Holding

The Seventh Circuit affirmed. Applying Ohio law under the engagement agreement’s choice-of-law clause, the court treated Sima’s theories as a legal-malpractice claim. Although the court described Barker’s conduct as troubling and defendants did not contest that Sima had pleaded a breach of duty, Sima did not plausibly allege that the breach caused compensable harm.

Sima failed to identify a colorable underlying claim that Barker caused her to lose. Her Colorado-based unfair-business-practices, unjust-enrichment, contract, and trade-secret theories were already time-barred when she retained Benesch, while possible Ohio unjust-enrichment and contract claims had substantial time remaining after the representation ended. The retainer was paid before the alleged misconduct, and the allegations did not meet Ohio’s demanding standard for emotional-distress damages. Without a viable malpractice claim against Barker, Sima’s vicarious-liability claim against Benesch also failed.

Key Takeaways

  • A legal-malpractice plaintiff must plausibly plead a causal link between the attorney’s misconduct and a concrete loss.
  • Even under Ohio’s lighter “some evidence” approach, a plaintiff alleging loss of an underlying claim must show a colorable claim the attorney caused her to lose.
  • An ethically questionable conflict alone does not establish malpractice damages, punitive damages, or law-firm vicarious liability.

Why It Matters

The decision underscores that malpractice claims based on a missed limitations deadline require specific allegations identifying the underlying claim, its applicable deadline, and why the attorney’s conduct caused its loss. General assertions that new counsel could not be retained or that a deadline was too near will not suffice.
