Nevada Supreme Court Rule 42(1)(a)(3) dictates that an out-of-state attorney must be admitted pro hac vice to participate in “all arbitration, mediation, or alternative dispute resolution procedures in this state that are court annexed or court ordered, or that are mandated by statute or administrative rule.” Likewise, pro hac vice admission is necessary for “all services incident to any of these proceedings including, but not limited to, discovery and settlement negotiations.” SCR 42(1)(a)(4). Nevertheless, “this rule does not apply to arbitration, mediation, or alternative dispute resolution procedures in which the parties engage voluntarily or by private agreement.” SCR 42(1)(b). Although the rule and exception have some ambiguity, I believe that, at a minimum, an attorney desiring to participate in a Nevada arbitration or mediation that has been ordered by a court should apply for pro hac vice admission.
