W. Va. Code § 56-8-4: Cases on review.

If, in any case of appeal, writ of error, or supersedeas, which is now or may hereafter be pending, there be at any time in an appellate court suggested, or relied on in abatement, the death of a party, or any other fact which, if it had occurred after verdict in an action, would not have prevented judgment being entered, as if it had not occurred, the appellate court may, in its discretion, enter judgment or decree in such case as if such death or such fact had not occurred.
