Appeal from the United States District Court for the Northern District of California Jacqueline Scott Corley, District Judge, Presiding

Submitted July 14, 2025**

Before: HAWKINS, S.R. THOMAS, and McKEOWN, Circuit Judges.

Vincent Robert Mackey, a prisoner proceeding pro se, appeals the district

* This disposition is not appropriate for publication and is not precedent except as provided by Ninth Circuit Rule 36-3. ** The panel unanimously concludes this case is suitable for decision without oral argument. See Fed. R. App. P. 34(a)(2). court’s summary judgment in favor of Defendants in his action under 42 U.S.C.

§ 1983. We have jurisdiction under 28 U.S.C. § 1291. We review de novo a grant

of summary judgment. Torres v. City of Madera, 648 F.3d 1119, 1123 (9th Cir.

2011). We affirm.

Mackey’s evidence does not raise genuine issues of material fact regarding

Dr. Cook’s alleged deliberate indifference. Dr. Cook saw Mackey repeatedly,

prescribed several types of treatment for common ailments consistent with his

symptoms, and referred him to specialists. Even crediting Mackey’s contention

that Dr. Cook failed to diagnose and treat the true causes of Mackey’s bowel

dysfunction, the evidence does not show that failure to be anything but inadvertent.

An unintentional failure does not rise to the level of an Eighth Amendment

violation. Toguchi v. Chung, 391 F.3d 1051, 1060 (9th Cir. 2004).

Mackey did not provide any evidence showing how the other named

doctors’ individual actions contributed to the alleged deprivation of his rights. As

for the defendants who were not his doctors, Mackey did not provide evidence that

they could be expected to “second-guess” medical professionals’ exercise of

judgment. Peralta v. Dillard, 744 F.3d 1076, 1087 (9th Cir. 2006). Nor has he

pointed to these officials’ implementation of any policy “so deficient” as to

constitute “a repudiation of constitutional rights.” Crowley v. Bannister, 734 F.3d

967, 977 (9th Cir. 2013). Given the absence of disputed issues of material fact, the

2 23-2893 district court’s grant of summary judgment was appropriate. Torres, 648 F.3d at

1123.

The motion to compel (Dkt. No. 29) is denied, because the defendants

fulfilled their obligations under this court’s order (Dkt. No. 18). We decline to

review evidence and argument raised for the first time in the motion.

AFFIRMED.
