Background and Experience

David Romyn joined Castle & Associates, APLC in 2003 as senior litigation counsel. For almost 20 years, Mr. Romyn has represented a broad range of individual and corporate clients drawn from the government contracts, construction, insurance, real estate, banking and manufacturing fields. Mr. Romyn has particular expertise in advising participants working in the construction industry in perfecting their contractual positions and resolving disputes during all phases in the start-up and performance of major public and private construction projects. He also has extensive experience in representing his clients in state and federal courts, in private arbitrations and before administrative boards on matters involving: bid protests, and other procurement and project delivery disputes; construction claims and requests for equitable adjustment; construction defects; union disputes and strikes; prevailing wage compliance; subcontractor substitutions; lien, stop notice and bond remedies; insurance claims; Cal-OSHA violations, and other matters of statutory and regulatory compliance.

Mr. Romyn is also recognized as an expert in “false claims” litigation. Mr. Romyn has been the architect of numerous successful defense strategies in California False Claims Act cases, challenging the government’s theories of falsity and disposing of numerous actions as a matter of law in pretrial motion practice. In this connection Mr. Romyn has successfully defeated government false claims act allegations of, “frontloading” bids; submitting false change order requests, and making “false certifications” of compliance with contractual and statutory provisions. Mr. Romyn has also successfully represented the firm’s clients against claims of business fraud, business torts, civil RICO and Unfair Competition.

Mr. Romyn has also successfully prosecuted numerous cases in the California Courts of Appeal. Notable cases include: Western Landscape Construction v. Bank of America (1997) 58 Cal.App.4th 57, 61, 67 Cal.Rptr.2d 868; and Pall Corporation v. Orange County Water Dist., 2004 WL 2943822.
