Before the Court is Defendants’ Motion to Preclude Plaintiffs’ Experts (Docs. 900,
16
905). Defendants seek to exclude the testimony of all seven of Plaintiffs’ experts in their
17
entirety. For the reasons that follow, the motion will be denied without prejudice to
18
renewed specific objections at trial.

I.
LEGAL STANDARD
20
When one party challenges another’s evidence, including expert evidence, Rule
21
104(a), Federal Rules of Evidence, requires the court to determine, by a preponderance of
22
proof, that the evidence is admissible. Daubert v. Merrell Dow Pharms., Inc., 509 U.S.
23
579, 592–93 & n.10 (1993). Daubert and Kumho Tire establish that district courts must
24
“ensure that any and all [expert] testimony . . . is not only relevant, but reliable.”
25
Daubert, 509 U. S. at 589; Kumho Tire Co. v. Carmichael, 526 U.S. 137, 147 (1999).
26
This does not mean that the party proffering expert testimony must “prove their case
27
twice — they do not have to demonstrate to the judge by a preponderance of the evidence
28
that the assessments of their experts are correct, they only have to demonstrate by a
1
preponderance of evidence that their [experts’] opinions are reliable.” In re Paoli R.R.
2
Yard PCB Litigation, 35 F.3d 717, 744 (3d Cir. 1994) (emphasis in original). Rule 702,
3
Federal Rules of Evidence, amended in 2000 to codify Daubert and Kumho Tire, states:
4
8
If scientific, technical, or other specialized knowledge will assist the trier of fact to
understand the evidence or to determine a fact in issue, a witness qualified as an
expert by knowledge, skill, experience, training, or education, may testify thereto
in the form of an opinion or otherwise, if (1) the testimony is based upon sufficient
facts or data, (2) the testimony is the product of reliable principles and methods,
and (3) the witness has applied the principles and methods reliably to the facts of
the case.
9
But again, “the test . . . is not the correctness of the expert’s conclusions but the
10
soundness of his methodology.” Daubert v. Merrell Dow Pharmaceuticals, Inc., 43 F.3d
11
1311, 1318 (9th Cir. 1995) (remand decision).
12
presentation of contrary evidence, and careful instruction on the burden of proof are the
13
traditional and appropriate means of attacking shaky but admissible evidence . . . [that
14
otherwise] meets the standards of Rule 702.” Daubert, 509 U.S. at 596.

“[T]he trial court must assure that the expert testimony ‘both rests on a reliable
17
foundation and is relevant to the task at hand.’” Primiano v. Cook, 598 F.3d 558, 564

(9th Cir. 2010) (quoting Daubert, 509 U.S. at 597).

relevant if the knowledge underlying it has a valid connection to the pertinent inquiry.
20
And it is reliable if the knowledge underlying it has a reliable basis in the knowledge and
21
experience of the relevant discipline.” Id. at 565 (citation and quotation marks omitted).
22
The Court must eliminate “unreliable nonsense opinions, but not exclude opinions merely
23
because they are impeachable.” Alaska Rent-A-Car, 738 F.3d 960, 969 (9th Cir. 2013).
24
The Ninth Circuit recently reiterated the appropriate inquiry: “The district court is not
25
tasked with deciding whether the expert is right or wrong, just whether his testimony has
26
substance such that it would be helpful[.]” Pyramid Technologies, Inc. v. Hartford Cas.
27
Ins. Co., 752 F.3d 807, 813 (9th Cir. 2014) (citing Alaska Rent-A-Car, 738 F.3d at 969).

“Expert opinion testimony is
1
Defendants do not challenge the relevance of Plaintiffs’ experts’ opinions.
2
Instead, they offer a number of arguments generally attacking the experts’ methodology:
3
e.g., they failed to use random sampling of records, reviewed an insufficient number of
4
records, failed to utilize a statistically significant sample size of inmates to draw a
5
random sample, did not perform statistical analyses, or used “cherry-picked information”
6
to form opinions (Doc. 905 at 3-18).1 The motion isolates but one aspect of the experts’
7
foundation for their opinions, statistical and sampling validity, and leaves untouched
8
those that rely on other evidence, including Arizona Department of Corrections’ written
9
policies, reports, business records, and officials’ deposition testimony.
10
For the moment, the Court defers discussing how best to resolve those challenges.
11
In their motion, Defendants have not “pointed to [any]thing which suggests that a
12
different but nonetheless sensible methodology for selecting files to review would have
13
materially altered the evidence before this court.” Coleman v. Wilson, 912 F. Supp. 1282,
14
1303 n.23 (E.D. Cal. 1995). Further, similar methodologies have been accepted in other
15
cases challenging prison conditions.
16
1847385, at *27 (D.N.J. June 25, 2007); Ruiz, 37 F. Supp. 2d at 889-92; Coleman, 912 F.
17
Supp. at 1303. But if Defendants’ statistical challenges are valid, the experts’ failure to
18
employ particular scientific methods in reaching their opinions does not necessarily
19
render all of their testimony unreliable.
20
Plaintiffs’ experts but do not articulate with specificity the opinions that suffer from fatal
21
defects. All of the challenges rest on the premise that the experts’ opinions are based on
22
scientific knowledge. To some extent Plaintiffs’ experts’ opinions are also based on
23
specialized knowledge, and none of the experts’ backgrounds or qualifications are
24
questioned.

Jama v. Esmor Corr. Servs., Inc., 2007 WL
Defendants request complete exclusion of
As to the non-statistical opinions, there has been no challenge to the
1
Defendants’ challenge Dr. Williams’ testimony regarding the impact of isolation
on geriatric inmates on the basis that the Court did not certify a sub-class of geriatric
inmates. Her testimony is relevant to whether those conditions pose a substantial risk of
serious harm to some inmates in isolation.

sufficiency of the “level of intellectual rigor that characterizes the practice of an expert in
2
the relevant field.” Kumho Tire, 526 U.S. 151-52; see also Ruiz v. Johnson, 37 F. Supp.
3
2d 885, 889-92 (S.D. Tex. 1999), rev’d and remanded on other grounds, 243 F.3d 941
4
(5th Cir. 2001) (an expert’s evaluation of a prison system’s quality of medical care, use
5
of force, or protection of inmates is not the type of testimony that necessarily implicates
6
Daubert’s requirement of scientific methodology.”).
7
Therefore, Defendants’ statistical challenge cannot in any event bear the weight of
8
excluding Plaintiffs’ experts’ opinions entirely.
The experts offered opinions as to
9
aspects of Arizona Department of Corrections’ health care system relying on other
10
sources of evidence. Complete exclusion, therefore, is not an appropriate remedy even if
11
Defendants’ statistical arguments were well-taken.
12
As to the statistical challenges themselves, they may have merit that would
13
exclude or limit some of the specific opinions. Of course, exclusion of any opinion or
14
limitation on an opinion from lack of scientific validity or reliability will be mandatory.
15
The Court as trier of fact will not have discretion to be persuaded by an opinion that falls
16
short of the minimums of Daubert and the Federal Rules of Evidence (thought it may be
17
persuaded to the same conclusion by other admissible evidence). But at this bench trial,
18
any such ill-founded opinion will become unpersuasive before it falls further to the level
19
of scientific unreliability. So as a practical matter, it is quite unlikely to matter at trial
20
whether the challenged opinions (or necessary qualifications on opinions) are admitted in
21
evidence or not. Unfounded opinions will be unpersuasive in any event.
22
Therefore, it is better to defer ruling on the challenges to admissibility of those
23
opinions to the time of trial or findings of fact and conclusions of law. This will impose
24
no great burden on Defendants, as they have prepared their counter-experts and will
25
present them anyway. Cross-examination of Plaintiffs’ witnesses may not be much more
26
extensive than if these challenges are resolved in their favor before trial. Even if it does
27
add material burden, the Court will be aided greatly by cross-examination and
28

1
understanding of the specific foundational challenges to specific opinions, which this
2
briefing does not fully explicate. That full understanding in context of trial may well
3
render some or many of Defendants’ challenges inconsequential. Equally important, the
4
usual need for pre-trial resolution of Daubert challenges, to avoid exposing the jury to
5
prejudicial inadmissible evidence, is not present in a bench trial.
6
economy overwhelmingly favor hearing the opinions, their bases, the cross-examination,
7
the counter-opinions, and the evidence as a whole. Deal v. Hamilton Cnty. Bd. of Educ.,
8
392 F.3d 840, 852 (6th Cir. 2004). The Daubert challenges can then be resolved if
9
necessary and with better accuracy.

10
In their reply, Defendants argue inconsistencies between the experts’ reports and
11
their declarations in opposition to this motion. Their cited authority, Weekes v. Ohio Nat.
12
Life Assur. Corp., 2011 WL 6140967 (D. Idaho Dec. 9, 2011), is inapposite to this case.
13
The better view is that the “sham affidavit” rule bars experts from later contradicting their
14
deposition testimony concerning the essential foundation of their opinions. However,
15
explanation that is reconcilable with the earlier deposition testimony is not barred under
16
the sham affidavit rule. Here too it is better to leave these challenges to be resolved after
17
trial and cross-examination.

With probing, apparent contradictions may become
19
For all these reasons, Defendants’ Motion to Preclude Plaintiffs’ Experts (Docs.
20
900, 905) will be denied without prejudice to renewal with specificity at trial. The Court
21
will reconsider this deferral to time of trial if necessary to rule on the pending motion for
22
summary judgment but only if necessary and only sua sponte.
23
Defendants make two final requests. The first is to limit an expert’s testimony to
24
the facilities he or she toured. But otherwise admissible testimony based on investigation
25
of some facilities but not all is still probative to some extent and any limitation goes to
26
the weight of the opinions.

Moreover, Defendants’ strenuous objections to the
28
-5-
1
limiting the number of tours, and the experts’ reliance on other evidence, which
2
Defendants do not discuss, all weigh against complete exclusion of the opinions. This
3
aspect of Defendants’ Motion will be denied.
4
Defendants also seek to exclude Dr. Cohen’s or Dr. Wilcox’s testimony as
5
cumulative. Duplicative expert testimony will be excluded, absent leave of the court.
6
Rule 403, Fed. R. Evid. (court may limit cumulative evidence and waste of time). Dr.
7
Cohen and Dr. Wilcox will not be permitted to testify to the same opinions. It appears
8
that they do have some opinions on differing issues. But to the extent their opinions are
9
on the same issues, Plaintiffs must elect which witness will testify on which issue. Once
10
one of them has testified to an opinion, the other will be precluded from testifying to the
11
same opinion. Defendants may raise such objections at trial in light of the testimony
12
given by the other witness.

15
IT IS THEREFORE ORDERED that Defendants’ Motion to Preclude Plaintiffs’
Experts (Docs. 905, sealed at 900) is denied without prejudice to renewal at trial.
