delivered the Opinion of the Court.
T1 In this original proceeding under C.A.R. 21, we consider whether a Colorado court has the authority to enforce a civil subpoena that was issued by an arbitrator against an out-of-state nonparty.
{2 In an arbitration proceeding between respondent SunOpta Grains and Foods Inc. ("SunOpta") and Colorado Mills, LLC ("Colorado Mills"), an arbitrator, at SunOpta's request, issued subpoenas to petitioners SK Food International ("SK Food") and Adams Vegetable Oil, Inc. ("Adams"). SK Food and Adams are not parties to the underlying arbitration. Neither company is incorporated in Colorado, is registered as a foreign corporation in Colorado, or maintains its principal office in Colorado. The subpoenas, which requested business records, were served on SK Food and Adams at their
13 When SK Food and Adams refused to comply with the arbitration subpoenas, Su-nOpta asked the district court to enforce them. The district court issued an order enforcing the subpoenas, and in response SK Food and Adams filed a petition for a rule to show cause, which we issued.
T4 We have long held that Colorado courts, as a matter of state sovereignty, have no authority to enforce civil subpoenas against out-of-state nonparties. See Solliday v. Dist. Court,
I.
15 In the case underlying this petition, Colorado Mills filed an action in Prowers County district court against SunOpta concerning a joint venture. The district court, in accordance with an arbitration agreement, ordered that the case be arbitrated. 1
16 SunOpta asked the arbitrator to issue subpoenas to SK Food and Adams seeking documents. SunOpta claimed that it required information from SK Food and Adams about the pricing of sunflower oil, contending that it could not compile the relevant pricing information from other sources. SK Food and Adams are not parties to the arbitration. Neither SK Food nor Adams is incorporated in Colorado, is registered as a foreign corporation in Colorado, or maintains its principal office in Colorado. The arbitrator issued the subpoenas, which were served on SK Food and Adams at their places of business in California and North Dakota. SK Food and Adams-customers of Colorado Mills and direct competitors of SunOpta-refused to comply with the subpoenas.
T7 When SK Food and Adams refused to comply with the subpoenas, SunOpta sought an order from the district court to enforce them. SK Food and Adams argued, inter alia, that the district court did not have the power to enforce the subpoenas against out-of-state nonparties. The district court granted SunOpta's motion and ordered SK Food and Adams to comply with the subpoenas. The district court held that it had jurisdiction to enforce the subpoenas based on Colorado's version of the Revised Uniform Arbitration Act, and that it had personal jurisdiction over both SK Food and Adams under the Colorado long-arm statute.
T8 Following the court's order, SK Food and Adams, as parties-in-interest, filed a petition for a rule to show cause pursuant to C.A.R. 21, which we issued.
19 We have long held that Colorado courts, as a matter of state sovereignty, have no authority to enforce civil subpoenas against out-of-state nonparties. See Solliday,
II.
T 10 The district court concluded that Colorado's version of the Revised Uniform Arbitration Act and the Colorado long-arm statute gave it authority to enforce the arbitration subpoenas against SK Food and Adams, both out-of-state

nonparties. We find that neither of these sources of law
{ 11 Colorado's version of the Revised Uniform Arbitration Act provides that an arbitrator "may permit such discovery as the arbitrator decides is appropriate in the circumstances, taking into account the needs of the parties to the arbitration proceeding and other affected persons...." § 13-22-217(8), C.R.S. (2011). If an arbitrator permits discovery, she may "issue subpoenas for the attendance of a witness and for the production of records and other evidence" at any hearing or discovery proceeding, including from nonparties. § 18-22-217(4); see also § 13-22-217(1). The question here is whether a Colorado court may enforce such a subpoena against a nonparty who is out-of-state.
«12 Section 18-22-217(1) does not expressly address the issue of enforcing subpoenas - against - out-of-state - nonparties. However, the act does provide that a subpoena "shall be served in the manner for service of subpoenas in a civil action and, upon motion to the court by a party to the arbitration proceeding or by the arbitrator, enforced in the manmmer for enforcement of subpoenas in a civil action." § 18-22-217(1) (emphasis added). The language of section 18-22-217(1) thus confines the district court's en-foreement authority in the arbitration context to that degree of authority it would possess "in a civil action." Accordingly, we reject any suggestion that the act gives a court greater authority to enforce civil subpoenas against out-of-state nonparties simply because the parties agreed to arbitrate. A district court has the same authority to enforce subpoenas in civil actions regardless of whether arbitration is involved or not.
113 We have long held that Colorado courts, as a matter of state sovereignty, have no authority to enforce civil subpoenas against out-of-state nonparties. In Solliday, for example, we held that an out-of-state nonparty "could not ... be forced by a Colorado court either to submit to the taking of his deposition [in another state] or to produce [documents]."
14 We reaffirmed Solliday in State of Minnesota ex. rel. Minnesota Attorney General v. District Court,
115 SunOpta contends, and the district court apparently agreed, that the limitations set forth in Solliday and reaffirmed in State of Minmesotao and Arellano-Avile do not apply, given that Colorado courts possess extraterritorial jurisdiction under the state's long-arm statute. § 18-1-124, C.R.S. (2011). We are not convinced.
1 16 We begin by noting that the language of the long-arm statute subjects resident and non-resident persons who have engaged in an enumerated act within Colorado to the "jurisdiction of the courts of [Colorado] concerning any cause of action arising from [the enumerated acts]." § 183-1-124. Here, however, Su-nOpta's subpoenas do not "concern[] any cause of action arising from" an act committed by SK Food or Adams. Therefore the long-arm statute does not apply. 3
118 We also note that, if SunOpta were correct, there would be no need for uniform acts to enforce civil subpoenas against out-of-state nonparties, as a state's long-arm statute would accomplish the task. Yet Colorado and other states recently adopted the Uniform Interstate Depositions and Discovery Act ("UIDDA"), which provides a mechanism for parties litigating in one state, the "trial state," to issue a subpoena to a nonparty in another state, the "discovery state." UID-DA §§ 1-9, 1311 U.L.A. 64-69 (Supp.2011); see §§ 13-90.5-101 to -107, C.R.S. (2011). Colorado's version of the UIDDA is not directly controlling in this case, as it governs how a Colorado court would enforce a "foreign subpoena" issued in another state for discovery within Colorado. § 18-90.5-103. However, the principles behind it are instructive.
19 Under the UIDDA, a subpoena issued in the "trial state" for discovery in the "discovery state" must be submitted to the clerk
20 SK Food and Adams make two additional arguments challenging the subpoenas issued in this case: that the information sought is a privileged trade secret and therefore not discoverable, and that the subpoenas issued here violate C.R.C.P. 45 on the ground that they seek documents only. 8 Because we find that the subpoenas are not enforceable by a Colorado court, we decline to address these additional arguments.
IIH.
1 21 For the foregoing reasons, we vacate the enforcement order of the district court, make the rule absolute, and remand the case to the district court for further proceedings consistent with this opinion.
Notes
. As the court compelling arbitration, the district court retains jurisdiction over the case. However, the arbitrator's decisions are final, subject to the limitations set forth in Colorado's version of the Revised Uniform Arbitration Act, sections 13-22-201 to -230, C.R.S. (2011).
. For the purposes of this opinion, we intend the term "out-of-state" to mean a nonresident who is not found within the state. We express no opinion on whether a nonresident nonparty served a civil subpoena while in Colorado may, as a result of such in-state service, become subject to a Colorado court's subpoena power.
. We also disagree with SunOpta's argument, based on Isis Litigation, L.L.C. v. Svensk Filmin-
. See, e.g., First Am. Corp. v. Price Waterhouse LLP,
. See, e.g., In re Nat'l Contract Poultry Growers' Ass'n,
. "Letters rogatory," also known as letters of request, are documents issued by a court in the trial state to a court in the discovery state, requesting that the discovery-state court take evidence from a person within the discovery state and return the evidence to the trial-state court for use in a pending case. Black's Law Dictionary 988 (9th ed. 2009). We note that a Colorado district court is authorized to send letters rogatory under C.R.C.P. 28.
. - Similarly, when the discovery state has enacted the Revised Uniform Arbitration Act, courts in the discovery state are authorized to enforce subpoenas from an arbitrator in the trial state. Revised Unif. Arbitration Act (2000), § 17(g), 7IA U.L.A. 61 (2011); § 13-22-217(7).
. C.R.C.P. 45 provides that subpoenas may be issued "to compel attendance of witnesses, with or without documentary evidence, at a deposition, hearing or trial." We have stated that this rule "does not permit a person to subpoena documents by themselves; rather, [documents] may be sought only in connection with a subpoena for a deposition."
