Before: SILVERMAN, LEE, and VANDYKE, Circuit Judges.
Former Oregon state prisoner Christopher Charles Mueller appeals pro se
from the district court’s summary judgment in his 42 U.S.C. § 1983 action alleging
deliberate indifference to his serious medical needs. We have jurisdiction under 28
U.S.C. § 1291. We review de novo. Wallis v. Baldwin, 70 F.3d 1074, 1076 (9th
Cir. 1995). We affirm in part, vacate in part, and remand.
The district court properly granted summary judgment on Mueller’s Eighth
Amendment claim arising from defendants’ treatment of his knee injury because
Mueller failed to raise a genuine dispute of material fact as to whether defendants
acted with deliberate indifference to his serious medical condition. See Estelle v.
Gamble, 429 U.S. 97, 104 (1976) (explaining the elements of an Eighth
Amendment claim based on medical care in prison); see also Toguchi v. Chung,
391 F.3d 1051, 1059–60 (9th Cir. 2004) (holding that a difference of opinion
between medical professionals concerning the appropriate course of treatment
generally does not amount to deliberate indifference to serious medical needs).
The district court granted summary judgment on Mueller’s Eighth
Amendment claim arising from the denial of his requests for a bottom bunk
assignment. However, defendants failed to demonstrate the absence of a genuine
dispute of material fact as to whether defendants Ackley, Mack, Stout, or French
refused Meuller’s requests for a bottom bunk despite knowing the risk it posed to
2 24-1270
Mueller’s health. See Nissan Fire & Marine Ins. Co. v. Fritz Cos., 210 F.3d 1099,
1106 (9th Cir. 2000) (“If a moving party fails to carry its initial burden of
production, the nonmoving party has no obligation to produce anything, even if the
nonmoving party would have the ultimate burden of persuasion at trial.”); see also
Akhtar v. Mesa, 698 F.3d 1202, 1213 (9th Cir. 2012) (holding that an inmate who
fell off his top bunk and broke his wrist stated a claim for deliberate indifference to
a serious medical need where defendants denied the inmate, a disabled man with
severe health conditions, a bottom bunk despite notice that the inmate required a
bottom bunk).
The district court did not abuse its discretion by denying in part Mueller’s
fourth motion to extend the time to file an opposition to defendants’ motion for
summary judgment because Mueller had over seven months to file an opposition
and failed to demonstrate good cause or excusable neglect. See Fed. R. Civ. P.
6(b)(1) (“When an act may or must be done within a specified time, the court may,
for good cause, extend the time. . . .”); Ahanchian v. Xenon Pictures, Inc., 624 F.3d
1253, 1258–59 (9th Cir. 2010) (setting forth standard of review and discussing
good cause requirement for extensions of time).
The district court did not abuse its discretion by denying Mueller’s motion to
strike Dr. Warren Roberts’s declaration. See Fed. R. Evid. 602 (explaining that
witnesses may testify to matters within their personal knowledge); 701 (explaining
3 24-1270
that lay witnesses may provide opinions rationally based on their perception); 702
(explaining that qualified experts may testify in the form of an opinion or
otherwise); Pyramid Techs., Inc. v. Hartford Cas. Ins. Co., 752 F.3d 807, 813 (9th
Cir. 2014) (setting forth standard of review and explaining that this court will
“reverse if the exercise of discretion is both erroneous and prejudicial”).
The district court did not abuse its discretion by denying Mueller’s second
motion to compel discovery because Mueller did not demonstrate actual and
substantial prejudice. See Hallett v. Morgan, 296 F.3d 732, 751 (9th Cir. 2002)
(setting forth standard of review and explaining that a district court’s decision to
deny discovery will not be disturbed except upon a clear showing that denial of
discovery results in actual and substantial prejudice).
The district court did not abuse its discretion by denying Mueller’s motions
for leave to file a supplemental complaint because supplemental pleadings cannot
be used to introduce a separate, distinct, and new cause of action. See Planned
Parenthood of S. Ariz. v. Neely, 130 F.3d 400, 402 (9th Cir. 1997) (setting forth
standard of review and grounds for supplementing a complaint under Fed. R. Civ.
P. 15(d)).
We lack jurisdiction to consider the district court’s denial of Mueller’s post-
judgment motion for reconsideration because Mueller failed to file a separate or
amended notice of appeal. See Fed. R. App. P. 4(a)(4)(B)(ii).
4 24-1270
The parties will bear their own costs on appeal.
AFFIRMED in part, VACATED in part, and REMANDED.
