Attorney Profile

Matt’s practice focuses on facilitating innovative change through legal action, and he works with private and public leaders in emerging issues and industries, ranging from internet to cannabis law.

Most recently, Matt was one of the lead drafting attorneys on California’s Proposition 64, the successful ballot initiative to decriminalize and regulate cannabis for adult use.  Working directly with then-Lt. Governor Gavin Newsom and other state leaders to craft the policy structure, Matt directly authored key provisions in the legislation, integrating complex legislative, political and legal considerations into a balanced, comprehensive and historic reform.

He is a member of the UCI Cannabis Institute legal task force, and also a guest lecturer on cannabis law at UCI Law School.  He also is a senior fellow for the Reason Foundation's Drug Policy Project, and has been published in a variety of periodicals.

Other Outstanding Achievements:

  • Drafting attorney, California Proposition 64, "Adult Use of Marijuana Act" (2016).  As part of the policy development and drafting team, Matt directly authored several provisions in the voter-approved initiative, after negotiating with a broad and diverse coalition of state leaders and stakeholders to carefully craft a balanced, comprehensive, yet flexible policy structure.  Given the state's sui generis size, complex legislative background, and unprecedented black/gray market operations, the legal and policy challenges were immense - making the effort (and the eventual landside passage by a record percentage) even more notable. , 2016
