Appeal from the United States District Court
for the District of Arizona
Douglas L. Rayes, District Judge, Presiding

Before: PAEZ, CHRISTEN, and KOH, Circuit Judges.
Natarajan Palaniappan and Satya Sree Dandamudi appeal pro se from the

affirm.
The district court properly granted judgment on the pleadings on the basis of
issue preclusion because the issues of whether Palaniappan participated in the
409A plan and whether the lump sum distribution was subject to income tax
withholding were actually litigated and decided in a prior bankruptcy proceeding.
See Janjua v. Neufeld, 933 F.3d 1061, 1065 (9th Cir. 2019) (setting forth
requirements for issue preclusion under federal law).
We do not consider matters not specifically and distinctly raised and argued
in the opening brief, or arguments and allegations raised for the first time on
appeal. See Padgett v. Wright, 587 F.3d 983, 985 n.2 (9th Cir. 2009).
AFFIRMED.
