Mohsen has been an architect of the winning legal strategy for multiple cases.

As a judicial clerk at both the U.S. Court of Appeals for the Eighth Circuit and the Supreme Court of Missouri, Mohsen focused on analyzing issues objectively and communicating clearly in writing. He now uses those skills to advance clients' positions. Mohsen has briefed issues in trial and appellate courts involving contractual interpretation, statutory interpretation, sovereign immunity, arbitration law, jury selection, evidentiary challenges, administrative law, and § 1983 litigation.

In his trial-level practice, Mohsen has first-chair arbitration experience and has helped prepare multiple complex commercial cases for jury trials. He has experience in motion arguments, depositions, factual investigation and development, expert witness preparation, and trial witness preparation.

Within the firm, Mohsen is on the St. Louis office’s Recruiting Committee and co-chairs the firm’s Asian, Pacific Islander, Middle Eastern, and North African Affinity Group. Mohsen is also active in the community, serving in various leadership roles in The Missouri Bar and on several boards in the St. Louis area.

Appellate Litigation

  • Orally argued, briefed, and won reversal in Missouri Court of Appeals, Western District in a contractual interpretation dispute between client (a large hospital system) and a health plan regarding whether client was a network provider under plan.

  • Orally argued, briefed, and won appeal in Illinois Second District Appellate Court regarding scope of "exclusive remedy provision" in Illinois workers' compensation statute.
  • Briefed and won application for transfer to the Supreme Court of Missouri in a case involving a venireperson for-cause challenge. Argued that court of appeals' decision made it significantly more difficult to rehabilitate a venireperson, in contravention of standard of review and statute governing for-cause challenge. Briefed and won transferred appeal.
  • Briefed and orally argued appeal in Illinois Fifth District Appellate Court, obtaining partial reversal on evidentiary issues—despite prior counsel not presenting any evidence at trial—in a sibling dispute over the guardianship of their mother's person and $750,000 estate. Argument focused on how trial court's decision was not supported by the evidence.
  • Briefed and won appeal in Missouri Court of Appeals, Eastern District, affirming trial court's decision to deny motion to compel arbitration. Presented an argument on appeal that was not presented at the trial court: the defendant did not meet its burden before the trial court to show that the Federal Arbitration Act applied, meaning the Missouri Uniform Arbitration Act applied. Then argued that the arbitration agreement did not meet the Missouri Uniform Arbitration Act's notice requirement, rendering the arbitration agreement unenforceable. The court of appeals agreed, invoking the general rule that a court can affirm on any basis in the record.
  • Briefed appeal in U.S. Court of Appeals for the Eighth Circuit, seeking affirmance of a trial court's early entry of summary judgment in a class action brought under the Missouri Merchandising Practices Act regarding price listings on gas pumps. Argued that trial court did not err in granting summary judgment because no reasonable consumer would be deceived by client's pricing display because display used simple language that is easy for reasonable consumers to understand. After filing brief, appellant agreed to dismiss appeal without any payout from client.
  • Briefed appeal in U.S. Court of Appeals for the Eighth Circuit, seeking affirmance of a trial court's grant of motion to dismiss on the grounds that client—a private entity that allegedly contracted with the state to provide services to probationers—was not a state actor subject to liability under 42 U.S.C. § 1983. Argument focused on how state did not delegate any constitutional duty or state function to client. After filing of brief, parties agreed to favorable, global settlement of this case and companion case.

  • Member of trial team representing natural gas company in a breach of lease dispute in Jackson County, Missouri circuit court. Obtained summary judgment two weeks before trial, which cut in half plaintiff's claimed damages. Limited jury verdict to $30,000, despite plaintiff requesting $1.3 million from jury. Briefed and orally argued motion for directed verdict, obtaining partial victory that removed two categories of damages. Briefed motion to strike one of plaintiff's expert witnesses based on that expert's opinion being largely parroted from unavailable witnesses; resulted in court limiting expert's testimony. Briefed motions in limine and assisted in witness preparation and other trial tasks.
  • Member of trial team representing pharmacy benefits manager in pharmacy contractual termination dispute where pharmacy sought over $30 million in damages against client, and client sought $20 million on counterclaim.

Following the denial of the preliminary injunction, citizen dismissed lawsuit.
  • Briefed, orally argued, and won motions to dismiss in state and federal court in a complex, publicized case brought under 42 U.S.C. § 1983 against client, a private drug rehabilitation facility that allegedly contracted with the state to provide services for probationers. Plaintiff argued that client failed to report certain information to the decedent's probation officer, causing the decedent's death. The federal court dismissed case, accepting argument that the client did not act under color of state law within the meaning of § 1983. The state court dismissed case, agreeing that the plaintiff did not plead facts establishing that the client's alleged failure to report treatment information to the decedent's probation officer proximately caused death.
  • Represented pharmacy benefits manager in pharmacy contractual termination dispute. Recognized early in case that named plaintiff did not have contract with client; instead, client had contract with named plaintiff's predecessor, which had violated contract by assigning it to named plaintiff in violation. Moved for summary judgment early in case based on that ground, which resulted in plaintiff voluntarily dismissing case with prejudice.
  • Represented paint and coating company in a breach of warranty lawsuit brought by construction company that purchased client's products. Obtain early favorable settlement and represented client at mediation, focusing on arguments that plaintiff improperly used client's products and that the bulk of plaintiff's claimed damages would be barred by the statute of limitations.
