On April 19, 2022, the Idaho Supreme Court issued its opinion in Nelsen v. Nelsen, ruling in favor of Parsons' clients on six of the seven issues. The 40-page opinion addressed numerous evidentiary issues, the summary judgment standard where a dispute is decided by the trial court rather than a jury, as well as claims involving testamentary capacity, undue influence, and the interpretation of Idaho operating agreements. The Idaho Supreme Court also formally declined to adopt the tort of intentional interference with an expected inheritance. This opinion was a significant win for Parsons' clients, and one that will likely be cited many times in the future.
