§ 27-3-406 — Determinations deemed conclusive; matters of law binding; limiting actions

(a) Except for reconsideration pursuant to W.S.
27-3-402(c) and 27-3-404(d), a right, fact or matter in issue
adjudicated in a final determination, redetermination or
decision on appeal under this article is conclusive for purposes
of this act. Subject to appeal proceedings and judicial review
and regardless of notice, a determination, redetermination or
decision on benefit rights is not subject to collateral attack
by an employing unit.
(b) Unless expressly or impliedly overruled by the
commission or a court of competent jurisdiction, principles of
law adjudicated under a final decision of the commission or an
appeal tribunal are binding on the commission, a special
examiner and an appeal tribunal in proceedings involving similar
questions of law.
(c) Any determination, redetermination, finding of fact,
conclusion of law, order, decision or final judgment entered or
made by a deputy, appeal tribunal, special examiner, the
department, the commission or a court of competent jurisdiction
pursuant to this act or the rules and regulations of the
commission is binding only between the department and all
adverse parties thereto, and is not binding, conclusive or
admissible in any separate or subsequent action or proceeding
between an individual and employing unit previously subject to
this act, regardless of whether the prior action before the
department or commission was between the same or related parties
or involved the same facts.
(d) Any determination, finding of fact, conclusion of law,
order, decision or final judgment, not made or entered by the
department or commission, is not binding upon the department
when administering this act except when the department or
commission was a party to an action or proceeding brought in a
court of competent jurisdiction of this state or of the United
States.
