Major 2026 Ruling: Insurance Malpractice Claims Barred by Washington Appeals Court

April 10, 2026 | JacobiJournal.com — A Washington Court of Appeals panel has ruled that a Great American insurance subsidiary cannot step into the shoes of an equipment manufacturer to pursue legal malpractice claims against two law firms involved in a prior injury-related dispute. The court determined that allowing such a transfer of claims would create a structural conflict between the insurer and the insured party, particularly given the contested liability issues arising from a climber’s fall incident.

The decision reinforces how courts are increasingly scrutinizing attempts by insurers to assert derivative legal claims that may undermine the independence of insured defendants in underlying litigation.

How Did the Court Block the Malpractice Claims?

The appellate panel concluded that the insurer lacked a proper legal basis to inherit the manufacturer’s malpractice claims against Gordon Rees Scully Mansukhani LLP and Sinars Slowikowski LLC. The court emphasized that derivative standing in legal malpractice actions requires alignment of interests between the assigning party and the assignee, which was absent in this case.

Because the insurer and manufacturer held potentially divergent positions in the underlying liability dispute, the court found that transferring malpractice rights could distort the adversarial balance in ongoing or related proceedings.

What Was the Underlying Insurance and Injury Dispute?

The dispute originated from a personal injury incident involving a climber’s fall allegedly linked to equipment manufactured by the insured company. The insurer, Great American, was involved in coverage and defense obligations tied to the manufacturer’s liability exposure.

During the course of the underlying litigation, questions emerged regarding legal representation quality and strategic decisions made by defense counsel. The insurer later attempted to assert malpractice claims against the law firms involved, arguing that prior legal conduct had increased exposure in the underlying case.

However, the appellate court found that this attempt blurred the legal separation between coverage interests and defense obligations.

Why Conflict of Interest Matters in Malpractice Assignments

The court’s reasoning centered on conflict-of-interest principles in insurance defense arrangements. When insurers attempt to assert malpractice claims derived from an insured party’s rights, courts closely examine whether those rights can be transferred without compromising loyalty obligations.

Here, the panel found that the insurer’s financial exposure and the manufacturer’s litigation posture were not fully aligned. This misalignment created a risk that assigning malpractice claims could indirectly influence defense strategy or settlement dynamics in the underlying dispute.

The ruling underscores a broader judicial reluctance to allow insurers to convert coverage disputes into third-party malpractice litigation.

How This Impacts Insurers and Defense Counsel Practices

This decision signals increased judicial caution regarding insurer-driven malpractice actions tied to defense counsel performance. Insurers may face additional hurdles when attempting to pursue recovery through derivative legal claims rather than traditional coverage litigation.

For defense law firms, the ruling reinforces the importance of clearly documented representation scope and maintaining independence from insurer influence in litigation strategy decisions.

The decision also highlights ongoing tension in insurance law between risk allocation and attorney accountability.
