How Judge Barbier decides

Patterns drawn from this judge's own signed orders. Every observation links to the order it came from.

What persuades

In toxic-tort / mass-tort cases he enforces the Fifth Circuit's strict general-causation gate: an expert must identify the harmful dose of a specific chemical; a non-case-specific report that names no chemical and no dose is excluded, which is usually fatal on summary judgment.

“Dr. Cook's report fails to identify a single chemical and, instead, refers generally to oil, dispersants, and volatile organic compounds. Moreover, even if Dr. Cook's report were to identify a specific chemical...his report fails to establish a harmful level of any chemical to the general population.”

On Sec.1983 false-arrest and Louisiana malicious-prosecution, an officer's own independent investigation (e.g. re-running an ID check) both breaks the chain of legal causation and supplies probable cause for qualified immunity, even if the investigation contained a mistake.

“the Constitution does not guarantee that only the guilty will be arrested, nor does it require officials to perform an error-free investigation.”

Procedural preferences

Treats Rule 54(b) certification of a partial final judgment as a rare exception, granted only on a real showing of hardship/injustice from delay -- not as a courtesy so a dismissed party can avoid monitoring the docket for an eventual appeal.

“Rule 54(b) judgments are meant to be the exception, not the rule, and the Court can find no danger of hardship of the type required to outweigh the policy preferences against such partial final judgments.”

In re Oil Spill by the Oil Rig "Deepwater Horizon" -- Findings of Fact and Conclusions of Law, Phase One Trial
2:10-md-02179-CJB-DPC · 2014-09-04

THE marquee Deepwater Horizon ruling (21 F. Supp. 3d 657). Rule 52(a) findings of fact and conclusions of law after the Phase One bench trial. EXCLUDED from motion stats (bench-trial findings, not a party-motion grant rate). Holdings, each verbatim from the GovInfo opinion: BP found RECKLESS while Transocean and Halliburton were merely negligent ("The Court further finds that BP's conduct was reckless. Transocean's conduct was negligent. Halliburton's conduct was also negligent." ¶543); comparative fault allocated BP 67% / Transocean 30% / Halliburton 3% (¶544); and BPXP held SUBJECT TO ENHANCED CWA CIVIL PENALTIES because the discharge resulted from its gross negligence and willful misconduct ("BP Exploration & Production, Inc. ('BPXP') is subject to enhanced civil penalties under the Clean Water Act ('CWA'), 33 U.S.C. 1321(b)(7)(D), as the discharge of oil was the result of BPXP's gross negligence and BPXP's willful misconduct." ¶611). Reasoning: "These instances of negligence, taken together, evince an extreme deviation from the standard of care and a conscious disregard of known risks." (¶520). The Court found BP's conduct egregious enough for punitive damages but held BP not liable for them under Fifth Circuit precedent (¶545). Affirmed by the Fifth Circuit.
