Predictably, the U.S. Supreme Court has ruled in Lamps Plus, Inc. v. Varela, No. 17-988, 2019 U.S. LEXIS 2943 (U.S. April 24, 2019), that, under the Federal Arbitration Act, neither silence nor “ambiguity” in an arbitration agreement regarding the permissibility of class arbitration enables a court to find that the parties agreed to permit class arbitration.  According to the Court, consent is fundamental to arbitration, and such an agreement must be express and unambiguous because it would so drastically alter the nature of the proceeding from the simple “bilateral” process that was envisioned in the FAA.
Can an arbitrator require an arbitrating party to post collateral prior to a hearing on the merits of the substantive claim(s) as security with respect to payment of a possible final award against that party?  And can such an interim award then be confirmed and enforced by a Federal court?  “Yes” and “yes”.  First, absent an agreed prohibition, it is usually within an arbitrator’s authority to take steps to insure that an eventual merits award will not be rendered meaningless, and requiring the posting of security to insure the payment of such an award is an unremarkable, if not well known, form of interim relief that an arbitrator can grant.  Furthermore, an interim award of this sort is considered final for purposes of judicial review, including confirmation.

What is a “Reasoned” Arbitration Award?

April 8, 2019 | Blog | By Gilbert Samberg

It is not unusual for an arbitration agreement to require, expressly or impliedly, a “reasoned award.”  Indeed, that is very likely.  And if the parties have stipulated that any award is to be “reasoned,” an arbitrator who fails to satisfy that requirement arguably is exceeding his/her powers by rendering an award in a non-compliant form, thereby making it vulnerable to vacatur under FAA § 10(a)(4).  So what is a “reasoned” award?
You are in federal court facing a motion to compel arbitration, and you reach for your well-worn copy of the Federal Rules of Civil Procedure in order to confirm how to go about your next step -- demanding a jury trial for example.  Better reach for your perhaps less well-worn copy of the Federal Arbitration Act (“FAA”) first.  Fed. R. Civ. P. 81 tells you that procedures set out in the FAA supersede the corresponding Federal Rules.  And then the courts weigh in and it gets complicated.

“Just What Was Needed”: Another Way to Waive a Right to Arbitrate

February 25, 2019 | Blog | By Gilbert Samberg

Want to give up a contractual right to arbitrate?  Easy.  Don’t seek to enforce it.  For example, just litigate for awhile and don’t mention your arbitration clause.  The court has no obligation sua sponte to raise or enforce your contractual right if you choose not to.

How to Enforce an Arbitration Subpoena: Jurisdiction and Venue Basics

February 11, 2019 | Blog | By Gilbert Samberg

The Federal Arbitration Act (“FAA”) §7 (9 U.S.C. §7) enables arbitrators to “summon … any person to attend before them or any of them as a witness and in a proper case to bring with him or them any [document] which may be deemed material as evidence in the case.”

Gateway issues of arbitrability are presumptively for a court, rather than an arbitrator, to decide in the first instance. First Options of Chicago, Inc. v. Kaplan, 514 U.S. 938 (1995). But arbitration is a creature of contract, and the parties to an arbitration agreement ultimately have the power to determine who is to decide such issues. Hence, that presumption may be rebutted by the parties’ clear and unmistakable manifestation of their mutual intention that an arbitral tribunal should have the exclusive authority to decide arbitrability issues in the first instance. Id.; Howsam v. Dean Witter Reynolds, Inc., 537 U.S. 77, 83 (2002). While the federal courts have been identifying examples of the practical application of those principles, many questions are still unanswered and some have barely been posed.

The U.S. Supreme Court has decided that the Federal Arbitration Act (“FAA”) requirement that courts enforce arbitration agreements according to their terms includes the parties’ agreement to have an arbitrator decide “not only the merits of a particular dispute, but also ‘gateway’ questions of ‘arbitrability’....”  Henry Schein, Inc. v. Archer & White Sales, Inc., No. 17-1272 (U.S. Jan. 8, 2019).  (As is customary, the rookie Justice (Kavanaugh, J.) delivered the Court’s unanimous opinion.)  This judgment, issued little more than two months after oral argument, shatters the “wholly groundless” doctrine, which purported to enable federal courts to adjudicate gateway arbitrability issues notwithstanding the parties’ clear and unmistakable delegation of such issues to an arbitral tribunal, if the court decided that the argument for arbitrability was “wholly groundless.”  (The Courts of Appeals were split on the viability of that doctrinal exception.)

Since arbitration is a process of dispute resolution in accordance with a private agreement, the question of consolidation of arbitral proceedings ought to be determined in the same manner as other procedural issues.  In short, no agreement to permit consolidation, no consolidation.

The Hong Kong International Arbitration Centre (“HKIAC”) has promulgated a new set of Administered Arbitration Rules (“AAR”), effective November 1, 2018.  Among those rules are Articles 27-30 concerning the HKIAC’s powers to join additional parties in an arbitration, to consolidate arbitrations, to consolidate related claims in a single arbitration, and to coordinate related unconsolidated arbitral proceedings.  Those powers, which the HKIAC can exercise without the consents of the parties to any bilateral arbitration agreement, are not trivial; among other things, they arguably institutionalize pathways to collective or opt-in class arbitration proceedings.
