Opinion

UNITED STATES DISTRICT COURT EASTERN DISTRICT OF TEXAS HOWARD GREGG DIAMOND, § § Movant, § § versus § CIVIL ACTION NO. 4:20-CV-397 § § UNITED STATES OF AMERICA, § § Respondent. § MEMORANDUM ORDER OVERRULING OBJECTIONS AND ADOPTING THE MAGISTRATE JUDGE’S REPORT AND RECOMMENDATION Movant, Howard Gregg Diamond (“Diamond”), a prisoner currently confined at USP Beaumont, filed a motion to vacate, set aside or correct sentence pursuant to 28 U.S.C. § 2255. Movant is represented by counsel, Gary Udashen. The court has received and considered the Report and Recommendation (“the Report”) of the magistrate judge filed pursuant to such order, along with the record, and pleadings (#82). The magistrate judge concluded that because Diamond failed to carry his burden under Strickland v. Washington, 466 U.S. 668, 687 (1984), his ineffective assistance of counsel claim cannot survive. The Report recommends that Diamond’s Motion to Vacate, Set Aside, or Correct Sentence be denied and the case be dismissed with prejudice. The Report also recommends that a Certificate of Appealability be denied. Diamond filed Objections to the Report (#83). This requires a de novo review of the objections in relation to the pleadings and applicable law. See FED. R. CIV. P. 72(b). In his Objections, Diamond maintains he is entitled to relief under § 2255 because he received ineffective assistance of counsel during the plea bargaining process. He objects to several findings of fact of the magistrate judge as well as the magistrate judge’s finding concerning prejudice. The court will take both in turn. A. Credibility Determinations

Diamond argues that several findings of the magistrate judge are contrary to the record and the law. Objections (#83 at 33-42).1 These disputed findings of fact rest on the magistrate judge’s determination of the credibility of the witnesses presented at the evidentiary hearing. Thus, at the heart of each of Diamond’s objections is a contention that his expert witness, Dr. Lindsey Thomas (“Thomas”), her affidavit, and the assertions in his pleadings are more credible than contrary assertions of fact by Diamond’s trial counsel, Peter Schulte (“Schulte”). Diamond asks the court to reconsider the evidence, reject the magistrate judge’s credibility determinations, and conclude that Thomas is more credible than Schulte and/or the evidence in the record.

Under 28 U.S.C. § 636(b)(1)(B), a district judge may “designate a magistrate judge to conduct hearings, including evidentiary hearings, and to submit to a judge of the court proposed findings of fact and recommendations for the disposition, by a judge of the court,” of “dispositive” motions. See United States v. Raddatz, 447 U.S. 667, 673 (1980). The statute further provides: A judge of the court shall make a de novo determination of those portions of the report or specified proposed findings or recommendations to which objection is made. A judge of the court may accept, reject, or modify, in whole or in part, the findings or recommendations made by the magistrate. The judge may also receive further evidence or recommit the matter to the magistrate judge with instructions. 1 The court notes that some of these “findings” are from the recitation of the factual background taken from the offense conduct as outlined in the Presentence Investigation Report (“PSR”). Diamond did not object to the offense conduct described in the PSR. Crim. ECF. Dkt. #89 at 4-8, §§ 9-22. 2 28 U.S.C. § 636(b)(1)(c) (emphases added). By its terms, § 636(b)(1)(c) grants the district court broad discretion to accept or reject the magistrate judge’s findings; however, this discretion is not unlimited. Under the terms of the statute, the district court may accept the credibility determinations

of the magistrate judge after reviewing the record, without conducting an independent hearing. See United States v. Scribner, 832 F.3d 252, 260 (5th Cir. 2016) (vacating the district court’s denial of a § 2255 motion because the decision was based on implicit rejection of the magistrate’s credibility finding without a hearing; explaining that, on remand, the district court was free to accept the magistrate’s credibility determination without holding a hearing, or in the alternative, reject the magistrate’s determination and come to its own conclusion after a hearing); Louis v. Blackburn, 630 F.2d 1105, 1009 (5th Cir. 1980) (“a district judge may accept a magistrate’s

findings concerning credibility and not violate due process.”); see also United States v. Marshall, 609 F.2d 152, 155 (5th Cir. 1980) (“a district judge who reviews the record of the hearing before the magistrate and adopts the magistrate’s recommendations need not conduct a new hearing.”). In contrast, a district court’s discretion to reject a finding of the magistrate is limited where: (1)the finding is based on the credibility of the witnesses the magistrate heard, and (2) the finding is dispositive of an application for post-conviction relief involving the constitutional rights of a criminal defendant. In Blackburn [the Fifth Circuit] held that in such circumstances the district judge cannot reject the finding without personally hearing live testimony from the witnesses whose testimony is in issue. Jordan v. Hargett, 34 F.3d 310, 313 (5th Cir. 1994), on reh’g en banc, 53 F.3d 94 (5th Cir. 1995); see also Scribner, 832 F.3d at 259 (explaining that a district judge may not reject the credibility finding of a magistrate judge without holding an evidentiary hearing); Garcia v. Boldin, 691 F.2d 1172, 1179 n.13 (“Where the district judge makes material credibility choices 3 at variance with those of the magistrate, the judge must, at least in certain cases, have a hearing at which he or she personally hears the testimony.”); Blackburn, 630 F.2d at 1110 (“If the district judge doubts the credibility determination of the magistrate, only by hearing the testimony himself does he have an adequate basis on which to base his decision.”).

Having made a de novo review of the record, including the transcript of the evidentiary hearing, the court is of the opinion that the Magistrate Judge’s credibility determinations are correct. The crux of the issue on remand is whether Schulte was ineffective for not consulting an expert witness in order to determine whether the evidence supported a claim that Diamond’s prescriptions were the cause of death of his patient T.H. For this § 2255 proceeding, Diamond retained Thomas as an expert who opined that T.H.’s death was most likely heat-related and not caused by Diamond’s prescriptions as, in her opinion, there was no oxycodone found in her

blood and the level of morphine found was not at a lethal limit. Thomas hinged her opinion on the email from the Government’s expert, Stacey Hail (“Hail”), but failed to mention that Hail herself questioned whether the toxicology report tested negative for oxycodone or if the assay itself was unable to detect oxycodone.
