UNITED STATES DISTRICT COURT EASTERN DISTRICT OF LOUISIANA

HEATHER DIODENE CIVIL ACTION

VERSUS NO. 21-491

MARLIN N. GUSMAN, ET AL. SECTION: “P” (3)

ORDER AND REASONS

Before the Court are: (1) the Daubert Motion to Exclude the Testimony and Report of Mary L. Livers (R. Doc. 164) filed by Plaintiff Heather Diodene; and (2) the Motion to Exclude Portions of the Opinions Offered by Plaintiff’s Proposed Expert, Roy Timothy Gravette (R. Doc. 165) filed by Defendants, Marlin N. Gusman, in his official capacity as former Orleans Parish Sheriff, Susan Hutson, in her capacity as Orleans Parish Sheriff, Chad Ruiz, Justin Andrews, and Chris Rubio (collectively, “OPSO Defendants”). Both motions are opposed.1 Having considered the motions, the parties’ memoranda, the record, and the applicable law, the Court resolves the motions as set forth herein. I. BACKGROUND Diodene instituted this action seeking damages for injuries she sustained after she was attacked by an inmate at the Orleans Parish Prison (“OPP”) in March of 2020.2 At the time of the incident, Diodene was employed by Wellpath, LLC (“Wellpath”) as a licensed practical nurse (“LPN”). Pursuant to a contract between Wellpath and the Orleans Parish Sheriff’s Office (“OPSO”), Wellpath provided health care services to inmates and detainees in OPSO custody at various detention centers in the New Orleans area. Diodene alleges that on March 10, 2020, she was performing her job duties as an LPN in the OPP’s intake processing center when an inmate

Doc. 1. impermissibly entered the restricted area designated for medical staff only and violently attacked her. Diodene further alleges that as a result of the attack, she suffered physical injuries (including severe injuries to her neck and back), emotional distress, pain and suffering, and lost wages. Diodene alleges the OPSO Defendants are liable to her for various federal constitutional violations,

breach of contract, and for their negligence, gross negligence, and intentional failure to provide a safe place to work.3 This case is set to be tried as a bench trial before the undersigned District Judge. All parties intend to present expert witnesses at trial and have exchanged the reports of their proposed experts. Diodene now seeks to exclude from trial all testimony and the report of the OPSO Defendants’ proposed expert, Mary L. Livers.4 And the OPSO Defendants seek to exclude from trial portions of the opinions offered by Diodene’s proposed expert, Roy Timothy Gravette.5 The Court considers the motions in turn below. II. Diodene’s Motion to Exclude Mary L. Livers Diodene moves the Court to exclude the testimony and report of Mary L. Livers for three

separate reasons. First, Diodene argues Livers’s expert disclosures do not comply with Federal Rule of Civil Procedure 26(a)(2)(B). Second, Diodene argues any testimony Livers might provide at trial cannot satisfy the requirements of Daubert or Federal Rule of Evidence 702. And third, Diodene argues Livers had an undue advantage in preparing her report because she was given the opportunity to conduct an inspection of the inmate processing center (“IPC”) at the OPP, meanwhile Diodene’s expert was denied the right to an inspection on the basis that an inspection posed a security risk.

3 See R. Doc. 1 (Complaint); R. Doc. 21 (First Supplemental and Amended Complaint); R. Doc. 46 (Second Supplemental and Amended Complaint). 4 R. Doc. 164. 5 R. Doc. 165. As to Diodene’s argument that Livers should be excluded from providing expert testimony because she had an undue advantage, the Court is not persuaded. In their opposition memorandum, the OPSO Defendants insist that it is incorrect that Diodene and her expert were not allowed to inspect the IPC. The OPSO Defendants contend Diodene and her expert were granted permission

to inspect the IPC subject to the condition that no photographs and videos would be permitted, and, according to the OPSO Defendants, Diodene’s expert chose not to inspect the IPC. Thus, because Diodene’s expert was provided the opportunity to inspect the IPC in the same manner as Livers, the OPSO Defendants argue there was no undue advantage given to Livers. Diodene did not respond to the OPSO Defendants’ argument. The record before the Court on this issue consists of nothing more than the contradictory assertions of counsel. Without more, the Court cannot find that Livers received an undue advantage such that the relief Diodene seeks—complete exclusion of Livers’s report and testimony in this matter—is appropriate. As to Diodene’s argument that Livers’s testimony must be excluded from trial because she cannot satisfy the requirements of Federal Rule of Evidence 702 and Daubert, the Court likewise

rejects this argument. Rule 702 provides: A witness who is qualified as an expert by knowledge, skill, experience, training, or education may testify in the form of an opinion or otherwise if the proponent demonstrates to the court that it is more likely than not that: (a) the expert’s scientific, technical, or other specialized knowledge will help the trier of fact to understand the evidence or to determine a fact in issue; (b) the testimony is based on sufficient facts or data; (c) the testimony is the product of reliable principles and methods; and (d) the expert’s opinion reflects a reliable application of the principles and methods to the facts of the case.6

And in Daubert v. Merrell Dow Pharmaceuticals, Inc., the Supreme Court held that Rule 702 requires the district court to act as a gatekeeper to ensure that any expert testimony presented is

6 FED. R. EVID. 702. both reliable and relevant.7 But courts have recognized that, in the context of a bench trial, the Court’s gatekeeping obligation is less important because the gatekeeper and trier of fact are the same.8 Here, Diodene challenges the admissibility of Livers’s testimony on the basis that her

report fails to provide the reasoning and methodology underlying her anticipated testimony. But, upon review of Livers’s report, it is clear to the Court that her anticipated testimony is based on her experience and specialized knowledge from her “over 40 years . . . in full time service as a corrections administrator of prisons, jails, community corrections, and juvenile corrections across four different states.”9 Any concerns Diodene has with Livers’s experience or its adequacy to serve as the basis of the testimony Livers will offer in this case may be addressed during cross- examination; and Diodene remains free to present contrary evidence as a means of attacking Livers’s testimony.10 If, after presentation of all the evidence, the Court finds Livers’s expert opinions to be unreliable, the Court can, and will, exclude her opinions from its consideration.11 Lastly, as to Diodene’s argument that Livers should be precluded from testifying in this

matter because her expert disclosures do not comply with the requirements of Federal Rule of Civil Procedure 26(a)(2)(B), the Court denies this request without prejudice, reserving Diodene’s right to re-urge its motion if the OPSO Defendants fail to comply with the Court’s orders set forth
