REDWOOD CITY, Calif. -

A billionaire technology mogul testified that he didn't recall details about the decision to deny public access to a once-popular Northern California beach.

Sun Microsystems co-founder Vinod Khosla appeared in a San Mateo County courtroom on Monday afternoon to testify in the civil dispute.

Khosla said he didn't remember seeing certain documents, including one from a judge saying he would need approval to close off access to the beach.

Khosla is accused of closing the only road that leads to Martin's Beach in violation of the California Coastal Act. The beach is about 35 miles south of San Francisco.

Without road access, Martin's Beach can only be reached from the ocean.

Khosla's attorney, Jeffrey Essner, says the public was previously allowed to access the beach for a fee, so there was never a right of public access.
