Thongvanh v. State
Annotate this Case
The Supreme Court affirmed the decision of the district court dismissing Appellant's application for postconviction relief (PCR) claiming a violation of his constitutional right to an impartial jury drawn from a fair cross section of the community, basing his claim on State v. Plain, 898 N.W.2d 801 (Iowa 2017), holding that the holding in Plain does not apply retroactively to cases on collateral review.
In 1984, Appellant was convicted of first-degree murder. In 2017, the Supreme Court decided Plain, which addressed the Duren three-part test for evaluating Sixth Amendment fair-cross-section claims and overruled precedent adopting the absolute-disparity method as the exclusive indicator of representativeness under the second prong of Duren. In 2018, Appellant filed the instant PCR application, alleging that he was denied his rights to due process, equal protection, and a fair and impartial trial under the state and federal constitutions. Appellant based his claim on Plain. The district court granted the State's motion to dismiss, concluding that Plain is not retroactive. The Supreme Court affirmed, holding (1) Appellant's Plain claim is time-barred by Iowa Code 822.3; and (2) because Plain's holding is not a watershed rule of criminal procedure, it does not apply retroactively to cases on collateral review.
