Opinion

GUARDANT HEALTH, INC., Case No. 21-cv-04062-EMC

Plaintiffs, ORDER GRANTING FURTHER v. COMPENSATORY SANCTIONS; DEFERRING ALLOCATION AND

Defendants. Docket No. 884 Before the Court are the Parties supplemental briefs regarding further monetary sanctions against Natera for the COBRA misconduct. See Docket Nos. 884-13, 887. This Court previously found “Natera’s counsel’s, Quinn Emanuel, deliberate misrepresentations, to this Court and Judge Kim . . . were unjustified, unacceptable and sanctionable.” Order Granting in Part and Deferring in Part Guardant’s Motion for Sanctions (“Prior Sanctions Order”), Docket No. 730, at 2. The Court granted evidentiary sanctions and deferred ruling on monetary sanctions. The Court ordered the parties to file supplemental briefs regarding monetary sanctions, including to “address specific individual attorney responsibility within Quinn Emanuel for the misconduct found.” Id. at 18. Guardant requests two actions from the Court. First, Guardant requests the Court award attorneys’ fees and costs in the amount of $2,985,909.63 in COBRA-misconduct related fees and costs. Reply at 12. Second, Guardant requests the Court award punitive sanctions, which would require a further hearing, and refer Quinn’s attorneys—Andrew Bramhall, Elle Wang, Brian Cannon, and Ryan Landes, who appear to have had a hand in this conduct—to the State Bar. enough, and now, particularly in light of the jury’s verdict, any further sanctions would be tantamount to a “windfall.” Natera also submitted declarations from each of the attorneys involved (claiming to have new evidence), where they swear under oath, all of the representations they made to the Court were done so with a “good-faith belief” of their truthfulness after relying on Dr. Hochster. Declarations at Docket No. 888-4 through 888-10. These declarations largely continue with the same narrative Natera’s counsel previously stated—they all relied on Dr. Hochster’s representations. Each attorney repeatedly states “I never made any knowing misstatement to the Court or to Guardant. My representations were all based on a good faith belief that they were true and accurate at the time they were made.” Natera’s counsel states they were “shocked” upon the discovery that Dr. Hochster actually had emails and had received an initial draft of the COBRA study results. The Court previously found this line of argument more than foolish. See Prior Sanctions Order at 13-14 (“While the Court labeled Natera’s counsel a ‘fool’ for (purportedly) believing Dr. Hochster’s testimony, it turns out that counsel was more than foolish. Quinn Emanuel deliberately and knowingly misled this Court. Given the correspondence Dr. Hochster had with Quinn Emanuel, counsel knew full well there had to have been email communications between Dr. Hochster the COBRA investigators.”). In view of the correspondence between Dr. Hochster and counsel, it was untruthful. In the alternative, Natera argues that if the Court finds attorneys’ fees and costs are warranted, Guardant’s requests should be reduced for fees and costs that fail the “but-for” causation standard. Under the Court’s inherent authority, the Court may “among other things, dismiss a case in its entirety, bar witnesses, exclude other evidence, award attorneys’ fees, or assess fines.” Am. Unites for Kids v. Rousseau, 985 F.3d 1075, 1088 (9th Cir. 2021). Sanctions are compensatory, as opposed to punitive, if the sanction is “calibrated to the damages caused” by the sanctionable conduct on which it is based. Id. at 1086. A district court acting under its inherent authority to should ask “but for the sanctionable misconduct, would there be any harm warranting compensatory relief?” Id. at 1089-90. If the answer is yes, the sanction is likely compensatory, whereas if the answer is no, the sanction is likely punitive and warrants a higher degree of due process afforded to the sanctioned party. Id. A. Bad Faith The Court has already held “monetary sanctions are likely appropriate due to Natera’s counsel’s, Quinn Emanuel, deliberate misrepresentations to this Court and to Judge Kim. Quinn Emanuel’s conduct, simply put, was unjustified, unacceptable and sanctionable,” Prior Sanctions Order at 2. Natera’s attorney declarations do not warrant a deviation from the Court’s prior finding of bad faith. Dr. Hochster and Quinn Emanuel on behalf of Natera, made misleading and false statements to Judge Kim, Guardant, and the undersigned, regarding Dr. Hochster’s email communications with COBRA investigators and the NRG, and his access to the study results, including his receipt of the draft abstract months in advance of his supplemental declaration seeking to introduce the COBRA study. These false and misleading statements that Dr. Hochster had no such documents were made with full knowledge of the truth to the contrary. And those misleading statements and untruths were used to gain a litigation advantage – to get this Court to reopen evidence to allow the introduction of the COBRA study long after discovery had closed and on the eve of trial. Relying on these misleading and false statements, this Court was duped into believing the COBRA evidence was late breaking and warranted reopening discovery and disrupting the trial schedule. Id. at 15. In short, but for the deliberate misrepresentation made to this Court, the Court would not have postponed trial and reopened discovery. The fees incurred by Guardant in connection with the reopening of discovery and preparation for an expanded trial based on the supposedly newly discovered COBRA trial results are a direct result of the sanctionable conduct. The “but for” test is satisfied as to those fees so incurred.
