Before: CALLAHAN, FRIEDLAND, and BRESS, Circuit Judges.
Lisa Gustafson Feis and Julien Feis appeal pro se from the district court’s
summary judgment in their diversity action alleging violations of Washington’s
medical malpractice law. We have jurisdiction under 28 U.S.C. § 1291. We
review de novo. Colwell v. Bannister, 763 F.3d 1060, 1065 (9th Cir. 2014). We
affirm.
The district court properly granted summary judgment for Dr. Boone,
Proliance Surgeons, Inc., and Proliance Orthopedics & Sports Medicine because
the Feises failed to raise a genuine dispute of material fact as to whether
defendants violated the standard of care or failed to obtain informed consent. See
Frausto v. Yakima HMA, LLC, 393 P.3d 776, 779 (Wash. 2017) (setting forth
elements of medical malpractice claim); Backlund v. Univ. of Wash., 975 P.2d 950,
957 (Wash. 1999) (setting forth elements of informed consent claim); see also
Wash. Rev. Code §§ 7.70.040 (elements of claim premised on a violation of the
standard of care), 7.70.050 (elements of claim premised on failure to obtain
informed consent).
The district court properly granted summary judgment for Dr. Mayo,
Swedish Health Services, and Swedish First Hill because the Feises failed to raise
a genuine dispute of material fact as to whether defendants’ conduct was a
2 24-3686
proximate cause of their injuries or whether defendants failed to obtain informed
consent. See Frausto, 393 P.3d at 779; Backlund, 975 P.2d at 957.
The district court properly rejected the Feises’ contention that the doctrine of
res ipsa loquitur applies to their medical malpractice claims. See Reyes v. Yakima
Health Dist., 419 P.3d 819, 824-25 (Wash. 2018) (explaining the limited
circumstances where res ipsa loquitur applies, including when acts are so palpably
negligent or are within a layperson’s general experience such that negligence can
be inferred without expert testimony).
We do not consider matters not specifically and distinctly raised and argued
in the opening brief. See Padgett v. Wright, 587 F.3d 983, 985 n.2 (9th Cir. 2009).
AFFIRMED.
