Narrative Opinion Summary
This case revolves around Massachusetts Mutual Life Insurance Company's (MassMutual) lawsuit against multiple corporate and individual defendants concerning residential mortgage-backed securities (RMBSs). MassMutual alleges violations of the Massachusetts Uniform Securities Act (MUSA), claiming defendants made material misrepresentations about the riskiness of the loans underlying these securities. The plaintiff seeks to establish liability under MUSA, which does not require proof of negligence, reliance, or loss causation. The defendants contested the admissibility of expert testimony from Dr. Charles D. Cowan, who proposed a statistical sampling methodology to identify misrepresentations in the loan origination process. The court denied the motion to exclude the testimony, affirming the methodology's reliability per Federal Rule of Evidence 702 and Daubert standards. MassMutual also pursues 'control person' liability against certain individuals for alleged misrepresentations in underwriting standards. The court's decision permits the use of statistical sampling to extrapolate findings across loan groups, maintaining that methodological rigor and representativeness are critical. The outcome allows MassMutual to proceed with its claims, with some cases stayed due to related bankruptcy proceedings.
