MINNEAPOLIS (LN) — The 8th Circuit upheld the dismissal of a legal malpractice lawsuit against AmLaw 200 firm Porter Wright, Morris & Arthur LLP, enforcing a choice-of-law clause that triggered Ohio's one-year statute of limitations for two claims and applying Minnesota's strict expert affidavit requirement to a third.

Everest Stables, Inc., a Minnesota corporation, and its CEO Jeffrey Nielsen sued Porter Wright and attorney Christopher D. Cathey, alleging the firm mishandled three prior legal matters involving equine assets and election campaign signs.

The 8th Circuit panel, consisting of Judges Shepherd, Erickson, and Grasz, affirmed the dismissal of claims related to the Foley and Dorsey matters because they were time-barred under Ohio law.

The court enforced a choice-of-law provision in the engagement letters for the Foley and Dorsey cases, which specified that Ohio law governed the attorney-client relationship. This provision triggered Ohio's one-year statute of limitations for legal malpractice, rather than Minnesota's six-year period.

Under Ohio law, the statute of limitations begins to run when the client discovers, or should have discovered, the injury related to the attorney's conduct, or when the attorney-client relationship terminates, whichever is later.

For the Dorsey matter, the court found the claim accrued on October 18, 2019, when a Minnesota state court granted summary judgment in part. The court noted that as Nielsen's counsel, Porter Wright was responsible for hiring an appropriate expert, and Nielsen should have discovered the injury related to the expert affidavit deficiencies at that point.

For the Foley matter, the claim accrued on April 25, 2019, when Porter Wright withdrew from representation. The court reasoned that Everest knew it was injured by the withdrawal because a critical motion was pending and Foley filed additional critical motions shortly after, as admitted in the complaint.

The plaintiffs argued they could not have discovered their injuries until all appeals in the underlying cases were exhausted. The 8th Circuit rejected this, citing Ohio precedent that a judicial decision adverse to the plaintiff is not required to start the malpractice clock.

The court also affirmed the dismissal of the third claim, involving attorney William Rambicure, due to the plaintiffs' failure to serve an expert disclosure affidavit as required by Minnesota Statutes section 544.42.

The statute mandates that plaintiffs in legal malpractice actions serve an expert affidavit within 180 days of the commencement of discovery. Failure to comply results in mandatory dismissal with prejudice if expert testimony is necessary to establish a prima facie case.

The 8th Circuit determined that expert testimony was necessary to prove the standard of care and causation in the Rambicure matter, particularly regarding the "but for" causation element required to show that the underlying case would have had a more favorable outcome.

The court rejected the plaintiffs' argument that prior judicial opinions conclusively established Porter Wright's breach of the standard of care. The court noted that issues such as the scope of discovery, the futility of claims, and the value of assets require expert legal knowledge to evaluate.

The dismissal also extended to derivative fraud, breach of contract, and breach of fiduciary duty claims, which the court found were subject to the same statute of limitations and expert affidavit requirements as the malpractice claims.

The case was appealed from the United States District Court for the District of Minnesota.
