Union Carbide Corp. Not Liable for Property Damage From 1984 Bhopal Leak

In the most recent case stemming from the 1984 chemical plant leak in Bhopal, India, the U.S. Court of Appeals for the Second Circuit further clarified the circumstances in which an entity other than the owner or operator of a site may be liable at common law for a chemical release at that site.  See Sahu v. Union Carbide Corporation, No. 14-3087-cv (2d Cir. May 24, 2016).  Plaintiffs claimed property damage from leaks from a waste storage facility at the Union Carbide India Limited (“UCIL”) plant in Bhopal, and sued Union Carbide Corporation (“UCC”), a majority stockholder in UCIL, for nuisance, trespass, strict liability, and negligence.

Maryland Court of Appeals OKs Circumstantial Causation Evidence in Lead Paint Cases

In a case that may make it easier to prove causation in Maryland lead paint cases, the Maryland Court of Appeals held that neither direct evidence of the source of lead nor expert testimony was necessary when a trier of fact had sufficient circumstantial evidence to conclude that the subject property was the “reasonable probable” source of lead exposure.  See Rowhouses, Inc. v. Smith, 133 A.3d 1054 (Md. 2016) Read More ›

Expert’s Specific Causation Methodology Unreliable in Leukemia Row

In a case underscoring the importance of reliable methodologies in expert testimony, the U.S. Court of Appeals for the First Circuit upheld a trial court decision excluding specific causation testimony linking benzene exposure and acute promyelocytic leukemia (“APL”) because the expert could not properly support her conclusions.  See Milward v. Rust-Oleum Corp., No. 13-2132, 2016 WL 1622620 (1st Cir. Apr. 25, 2016). Read More ›

Sixth Circuit Requires Expert Testimony to Prove Causation in Paper Mill Nuisance Case

Bolstering the defense view that competent expert testimony is typically required to prove causation in toxic tort actions, the U.S. Court of Appeals for the Sixth Circuit granted summary judgment dismissing property owners’ claims that the Defendant paper mill’s effluent interfered with their right to use and enjoy property. See Freeman v. Blue Ridge Paper Prods., No. 12-6259 (6th Cir. July 9, 2013), available at www.bdlaw.com/assets/attachments/FreemanvBlueRidgePaper.pdf.

See Junk v. Obrecht, No. 3-454 (Iowa Ct. App. Sept. 5, 2013), available at www.bdlaw.com/assets/attachments/JunkvObrecht.pdf. Read More ›

California Trial Court Rejects Defense Argument That State Must Establish Locations with Specificity in Statewide Lead Paint Suit

Refusing to require plaintiffs in a state-wide action to identify specific sites at issue, a California Superior Court judge denied summary judgment to certain paint manufacturers in a pending nuisance action for abatement of lead-based paint in homes and buildings throughout the State of California.
