SACRAMENTO, Calif. -

Attorneys are arguing in a Sacramento County Court that California's high-speed rail agency has broken a promise made to voters who approved selling $10 billion in bonds to build the nation's first bullet train.

They argued Friday in a lawsuit that claims the state has not identified adequate future funding for the $68 billion project or secured all the environmental permits for construction to start, as required in the 2008 measure.

The state has only a fraction of the money needed.

Farmers, landowners and the Kings County Board of Supervisors sued to stop the state from spending any more bond money.

Attorneys for the state say Proposition 1A required the agency to provide information to the Legislature, not voters, and itf did so in a funding plan lawmakers approved.
