KAVANAUGH, J., delivered the opinion of the Court, in which ROBERTS, C. J., and ALITO, GORSUCH, and BARRETT, JJ., joined. JACKSON, J., filed a dissenting opinion, in which SOTOMAYOR and KAGAN, JJ., joined in full, and in which THOMAS, J., joined as to Parts II, III and IV.
JUSTICE KAVANAUGH delivered the opinion of the Court. When a
federal district court denies a motion to compel arbitration, the losing party
has a statutory right to an interlocutory appeal. See 9 U. S. C. §16(a). The
sole question here is whether the district court must stay its pre-trial and
trial proceedings while the interlocutory appeal is ongoing. The answer is yes:
The district court must stay its proceedings.
