Id.; see also ARMA, S.R.O. v. BAE Sys. Overseas, Inc., 961 F.Supp.2d 245, 268 (D.D.C. 2013) (discussing Supreme Court’s equivocation in Hall Street Associates, 552 U.S. at 585, 128 S.Ct. 1396, on whether manifest disregard of law can be basis for vacatur of arbitral award). The Court thus considers the issue forfeited. Huntington v. Dep’t of Commerce, 234 F.Supp.3d 94, 101, 2017 WL 211301, at *4 (D.D.C. Jan. 18, 2017); Gold Reserve Inc. v. Bolivarian Republic of Venezuela, 146 F.Supp.3d 112, 126-27 (D.D.C. 2015) (<HOLDING>); see Hutchins v. District of Columbia, 188
