OAKLAND — The California Fair Political Practices Commission slapped Oakland Mayor Ron Dellums with a $200 fine Thursday for failing to disclose a trip to South Africa on a statement of economic interests.

Dellums made the journey in 2008 on the South African government's dime to receive an award for his work to end apartheid. Lodging and transportation totaling $28,750 were granted free and should have been reported as gifts, the commission said.

The statements of economic interests, called Form 700s, require state and local officials to disclose certain kinds of outside income, investments, property, gifts and, in some cases, travel paid for by outside parties.

The mayor declared no reportable interests for 2007 or 2008. That drew scrutiny from reporters, and the mayor's office acknowledged in November that the trip should have been listed.

"At the time the Form 700 was due, we believed that since it was a government entity providing the funds, we didn't have to disclose it," Dellums spokesman Paul Rose said. "After conducting a review of the situation, we determined the trip should have been disclosed."

Rose said the Form 700 has been amended to include the trip.

The $200 penalty was approved by the commission during a monthly meeting Thursday. Dellums is required to pay the money to California's general fund.
