[2] Court is the author of Corporateering: How Corporate Power Steals Your Personal Freedom[3] and the co-author of Making A Killing: HMOs And The Threat To Your Health.

[2] Upon graduation in 1989, Court canvassed door-to-door to raise money for the enforcement of insurance reform ballot initiative California Proposition 103, which passed on November 8, 1988.

Court began his career at Consumer Watchdog as the head of Californians for Quality Care, working to reform the HMO system in the state.

For example, during a legislative meeting in Sacramento, Court and his team placed a red herring on the table to signify that the proposed HMO reform was a deliberate attempt to divert attention.

[2] He also created a daily "HMO casualty of the day," where he faxed patient faces and stories to lawmakers to show how HMOs were hurting citizens of the state.

[12][13] In 1998, Consumer Watchdog advocated for legislation, ultimately signed into law by California Governor Gray Davis, to extend broad need rights to HMO patients.

As a result of his tactics, and the signature gathering help of e-loan's Chris Larsen, Governor Davis signed the "country's toughest financial privacy legislation.

To raise awareness of the fact that an insurance company was trying to hide its sponsorship of Proposition 17, and its CEO was afraid to debate the merits of the proposal in public, the group sent a man in a chicken suit to legislative hearings on the measure.

[24] Also in 2010, the group created a cartoon video of Google CEO Eric Schmidt as an ice-cream truck driver interested in gathering data about the children on his route.

[27] In 2017, a Los Angeles Times investigation found that Court and Consumer Watchdog do not disclose contributions to their nonprofit organization, raising questions about certain actions the group has taken.

[28] In 2023, a Politico article described Court's recent successes with Governor Gavin Newsom's administration, having "chalked up some significant policy wins as the costs of climate change have started hitting people's pocketbooks," and noted criticism that he had previously been tagged a "complainer for hire".

[30] Published in 1999 by Common Courage Press, Court, with co-author Francis Smith, wrote Making a Killing: HMOs and the Threat to Your Health.

"[35] Court's newest book, The Progressive's Guide to Raising Hell: How to Wage Winning Campaigns, Pass Ballot Box Laws and Get the Change We Vote For was released September 15, 2010 by Chelsea Green Publishing.
