Jason Moberly Caruso is a partner in the Newport Beach office of Newmeyer Dillion. His practice focuses on various aspects of land use, “contaminated sites” environmental matters, complex litigation, and appellate matters.

Environmental Litigation & Regulatory Matters

Jason counsels and represents current and former facility owners and operators in state and federal proceedings, administrative actions, cost recovery cases, and non-litigation site remediation situations. The litigated matters frequently involve the federal Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and its parallel California Hazardous Substances Account Act (HSAA). Jason’s counsel reflects an overlay of the technical, regulatory, and legal dynamics inherent in contaminated sites, often during real estate transactions or when seeking no-further-action determinations. Further, Jason specializes in Proposition 65 warnings for property owners and producers/distributors of consumer products regarding hazardous substance exposures., in both litigation, pre-litigation, and counseling contexts.

Land Use & Entitlement Issues

Jason also counsels and represents developers regarding land use and entitlement issues, from the pre-entitlement phase through construction, including associated administrative proceedings.  Jason is well versed in the Housing Accountability Act, the “Builder’s Remedy,” and related statutory mandates, as well as permit streamlining and exaction issues.  Jason has represented developers in litigation matters as well, and has a proven track record of obtaining and defending approvals of contested projects.

Complex Litigation & Appellate Matters

When clients must go to court, Jason applies his significant experience in complex state and federal litigation over a broad range of substantive areas, including environmental, business, real estate, construction, and products liability. His experience extends from pre-litigation through trial and post-trial proceedings.

Jason has particular expertise in appellate matters, and has obtained victories for clients in general appellate and extraordinary writ proceedings in state and federal appellate courts. Jason has presented oral argument in appeals before the Ninth Circuit Court of Appeals and the California Court of Appeal.

Community Engagement
