The Wyoming Supreme Court has held that a legal malpractice claim against a convicted defendant’s public defenders 

In 2016, public defenders Donald Miller and Robin Cooper represented
Mr. Dockter in his criminal trial. The jury convicted Mr. Dockter of kidnapping,
unlawful entry, misdemeanor theft, property destruction, interference with an emergency
call, and domestic battery. Dockter v. State, 2017 WY 63, ¶ 8, 396 P.3d 405, 407 (Wyo.
2017) (Dockter I). Mr. Dockter appealed his kidnapping and misdemeanor theft
convictions and Eric Alden, an attorney with the appellate division of the Wyoming
Office of the State Public Defender, represented him.

The court rejected an exoneration requirement

We turn next to the exoneration rule to determine if it applies to bar this malpractice suit. The district court held that the exoneration rule applied to Mr. Dockter’s malpractice suit and was “equally dispositive.” This Court has never before considered whether to adopt the exoneration rule, and we decline to do so now.
