The case involved 13 California state cases coordinated under a Judicial Council Coordination proceeding (JCCP) regarding the drug of Onglyza and Kombiglyze which contained the active ingredient saxagliptin a medicine for type 2 diabetes. Plaintiffs’ alleged that they were injured as the active ingredient can cause heart failure.  The trial court ordered the parties to conduct discovery in phases.  The first phase covered percipient and expert discovery on the issue of general causation, noting that the litigation would then proceed as to other issues only if plaintiffs were able to show that the defendant’s drugs caused the injuries alleged.  Following expert discovery, the defendants moved to exclude Plaintiffs’ causation expert, a Dr. Goyal.  Defendants’ claimed in a Daubert/Sargon hearing that Dr. Goyal was either unqualified to offer his proposed opinions, or that the basis of the opinions were incomplete and didn’t support causation.  Continue Reading Beware if Your Expert is Disqualified!!

Many lawyers use the terms “supplemental expert” and “rebuttal expert” interchangeably, but, according to the Discovery Act, they are very different. A supplemental expert  is one that was disclosed twenty days after experts have been disclosed and is pursuant to Code of Civil Procedure section 2034.280 and is allowed to provide expert testimony. However, a rebuttal expert’s testimony is limited to rebutting or contradicting an opponent’s  expert’s “foundational facts” that form the basis of their opinion.

See Evid Code §606 on the effect of a presumption. To prevent disqualification, the presumption must be rebutted with an affirmative evidentiary showing that no confidential materials were transmitted.
