In this appeal we decide whether David Webster filed his motion to vacate an arbitration award in federal district court one day too late. The district court concluded that the motion was untimely, having determined that the statute of limitations began to run when the award was placed in the mail and stopped when the defendants were served with notice of Wеbster’s motion three months and one day later. Webster contends that both dates were improper benchmarks. We conclude that under § 12 of the Federal Arbitration Act (“FAA”), Webster’s motion was untimely. In reaching this decision, we have found it necessary to clarify our prior decisions concerning the critical dates for purposes of the FAA’s three-month limitations pеriod.
I.
A.T. Kearney, Inc. hired Webster as General Counsel in 1994. The following year, Electronic Data Systems Corporation acquired A.T. Kearney. After working for the new entity for a number of years, Webster lost his job when A.T. Kearney’s legal department was eliminated. He brought claims against the defendants (collectively “EDS”) for age discrimination and breach of his 1995 Employment Agreеment. That agreement contained a mandatory arbitration provision, under which the parties agreed to arbitrate employment disputes according to the procedures of the *570 American Arbitration Association (“AAA”). Accordingly, Webster filed a demand for arbitration in October 2003, and, after nearly two years, a hearing was held. Ultimately the AAA-appointеd arbitrator found for EDS.
The arbitrator issued the award on January 4, 2006. That same day, the award was placed in the mail and also distributed to both parties’ counsel via e-mail. A cover letter dated January 4 accompanied both disseminations. Webster’s attorney, Norman Lerum, first opened the e-mail on January 5, although he acknowledges that the message was “received” by his “office computer” on January 4. Unsatisfied with the arbitrator’s decision, Webster sought to overturn the award on the ground that the arbitrator had exceeded his authority, see 9 U.S.C. § 10(a)(4). Toward that end, he filed a motion 1 to vacate the award in federal district court on April 3, 2006, and served EDS with notice of the motion on April 5. EDS responded by moving to dismiss Webster’s action as untimely.
The FAA provides that when a party moves to vacate, confirm, or modify an arbitration award, notice “must be served upon the opposing party or his attorney within three months after the award is filed or delivered.” 9 U.S.C. § 12. EDS argued that the award was “delivered” for purposes of the FAA when it was placed in the mail on January 4, or alternatively when it was e-mailed the same day. EDS further maintained that it was “served” when it received notice of the filing of the federal action on April 5 — one day after the three-month anniversary of the award’s delivery. The district court took the delivery date to be January 4, when the e-mail was sent and received (although not opened). The court held that the statute of limitations expired on April 4, exactly three months later, rendering Wеbster’s federal action untimely.
II.
We note at the outset that, although the parties agree that our review is
de novo,
they dispute whether this appeal is from the denial of a motion to dismiss under Federal Rule of Civil Procedure 12(b)(6) or a motion for summary judgment under Rule 56. They are both mistaken, and we are puzzled by the way the parties’ attorneys — who purport to be experiеnced with litigation under the FAA — proceeded in the district court. Under the FAA, “[a] ny application to the court hereunder shall be made and heard in the manner provided by law for the making and hearing of motions.” 9 U.S.C. § 6. This provision of the FAA, we have held, removes actions to confirm or vacate arbitration awards from the realm of civil cases governed by the Fedеral Rules of Civil Procedure.
See
Fed R. Civ. P. 1, 81(a)(3);
Health Servs. Mgmt. Corp. v. Hughes,
Accordingly, the procеdures used in this case diverged from those required by the FAA. No “complaint” or “motion to dismiss” or any other filing conceived by the Federal Rules of Civil Procedure need have been filed. Webster, as the party challenging the award, should have filed a motion to vacate and “providfed] the Court with all matters that it desires the Court to consider in support” of that motion.
Hughes,
On appeal, Webster argues that his motion was timely for a number of reasons. We begin with the more straightforward issue of when the three-month statute of limitations ceases to run. Webster contends that the filing of a motion to vacate is the relevant benchmark because filing signals the commencement of a federal action. EDS contends that the phrase “service of notice” in § 12 of the FAA should be construed literally to mean that the limitations period stops only when notice is served.
The rule that Webster suggests has no grounding in the plain language of the relevant statute, and that is where our inquiry begins and ends, absent some ambiguity.
See Greenfield Mills, Inc. v. Macklin,
Before moving on, we wish to clarify some of our previous statements about the tolling date. The parties point out, correctly, that at least two of our past decisions could be read to provide some support for Webster’s position that the statute of limitations stops upon the
filing
of a motion to vacate or otherwise alter an award.
See Olson v. Wexford Clearing Servs. Corp.,
Next we must decide whеn the statute of limitations began to run. The candidates are January 4, when the award was placed in the mail, e-mailed by the AAA, and received by Lerum (Webster’s counsel) at his “office computer”; January 5, when Webster first opened the e-mail from the AAA; and January 9, when Lerum received the arbitrator’s award in the mail. Webster maintains that the period began to run when he received the mailing, or at the very earliest when he opened the email attachment.
Under 9 U.S.C. § 12, the three-month period begins running when the arbitration award is “filed or delivered.” Surprisingly, few decisions have directly addressed what it means for an award to be “delivered.” Moreover, courts have imprecisely substituted a number of other terms for “delivery” without explanatiоn. 2 We need not dwell long on statutory interpretation or judicial construction of the term, however, because the parties in this case agreed *573 to proceed under the rules of the AAA, and those rules supply the definition.
Under the terms of an addendum to Webster’s Employment Agreement, the parties agreed to arbitration “pursuant to AAA procedures.” Acсordingly, the arbitration proceeded according to the September 2005 version of the AAA’s National Rules for the Resolution of Employment Disputes. 3 Two rules are relevant here. First, Rule 33 provides that the parties are deemed to have consented to service by mail of all “papers, notices, or process” relating to the arbitration, including “the entry of judgment on an award made under these proсedures.” Second, Rule 34(g) provides in relevant part: “The parties shall accept as legal delivery of the award the placing of the award or a true copy thereof in the mail.”
We conclude that the clear mutual consent to service by mail, coupled with the definition of “delivery” as placement in the mail, establish that, at least for purposes of this case, the award was “delivered” on January 4 when the AAA case manager placed the award in the mail. Webster’s objections to this position are unconvincing. He contends that his consent to service by mail under Rule 33 extends only to service of papers “other than the arbitration award,” but we find no support for this proposition in the languаge of the rule. And even if Webster is correct that Rule 34 is the only one that pertains to awards, that rule establishes that delivery of an award is “the placing of the award or a true copy thereof in the mail.” Thus, the date the award was placed in the mail — January 4 — controls.
We note for the sake of completeness that the only other federal aрpellate court to decide what “delivery” means for purposes of the FAA’s statute of limitations came to a different conclusion. In
Sargent v. Paine Webber Jackson & Curtis, Inc.,
Of course, the physical mail was not the only form of notice in this case. EDS argues, and the district court concluded, that January 4 is the date of delivery for the alternative reason that the award and cover letter were sent to both parties as email attachments on that date. Webster’s attorney acknowledges that his “office computer received [the award] by email” on that date, but insists that the relevant “delivery date” — if e-mail is ever proper notice, which he disputes — is the date on which he opened the e-mail, January 5. We are inclined to agree with the district court that electronic “delivery” oсcurred when the e-mail was sent on January 4. Under the AAA rules, placement in the mail signifies delivery of postal mail, so we see no reason to apply a different standard to email. Moreover, Webster’s proffered interpretation — ’that delivery occurs when an e-mail is first opened — would allow a party to postpone the statute of limitations indefinitely simply by ignoring his cоrrespondence. Notably, Webster does not argue that postal mail is “delivered” only when the recipient opens the envelope; instead he argued that January 9, the date he received the written award, was the operative date.
All this is academic, if, as Webster contends, e-mail transmission can never constitute proper delivery of an award unless the parties explicitly consented to this form of notification. For support, he turns to the AAA Rules, under which, as we have seen, the parties are deemed to have consented to service by mail. Although under Rule 33 the parties “may” consent to notice through electronic means, consent to such notice is not implied. We are skeptical of Webster’s assertion that he never consented to e-mail transmission because the record reveals that a great deal of communication between the parties and the AAA was accomplished through e-mail. In particular, it appears that a number of scheduling orders were disseminated to the parties only through e-mail. Still, we are reluctant to hold, absent evidence of an express agreement betweеn the parties, that his use of electronic communication for certain matters constituted consent to accept delivery of the award by e-mail. We will leave that decision for another case, because our conclusions with respect to the mailing of the written award foreclose Webster’s argument that his motion was timely.
III.
Because thе statute of limitations began to run when the award was placed in the mail on January 4, 2006, and expired three months later on April 4, Webster’s motion to vacate the arbitration award was untimely. Service of notice on EDS, on April 5, occurred one day too late, and denial of the motion to vacate was proper. Accord *575 ingly, the judgment of the district court is
AFFIRMED.
Notes
. As we will discuss further, the motion wаs erroneously styled as a "complaint” and the case was treated by both parties and the district court as a new civil litigation, including the filing and granting of a "motion to dismiss” under Federal Rule of Civil Procedure 12(b)(6). This is contrary to § 6 of the FAA, which provides that actions to challenge or confirm arbitration awards “shall be made and heard in the manner provided by law for the mаking and hearing of motions.”
. For instance, multiple courts, including this one, have implied (in dicta) that the parties have three months from when the award is “issued” or "entered” to file a motion.
See Olson,
. The Rules have since been amended and the ones we discuss have since been renumbered.
. We would note that this case demonstrates that equating ''delivery” with “receipt” does not solve everything; there can still be multiple definitions of “receipt” such as those proposed by Webster. Is the award "received” when an e-mail is sent and delivered or when it is read? Is "receipt” the arrival of a letter at the destination address, or the opening of the letter by the proper party? However, the D.C. Circuit helpfully noted in
Sargent
that the case was not one in which a potential distinction between receipt and delivery "could play a role.”
