An Oakland councilwoman Wednesday blamed a staff error for a form claiming free tickets for herself and a family member to the city’s Oracle Arena luxury suite for a potential sixth Golden State Warriors NBA finals game June 13.

Oakland officials who use those tickets at the venue jointly owned by the city and county must declare an official purpose for attending, such as to inspect the facility’s operations or rewarding community volunteers and students.

An online form approved and posted Monday said Councilwoman Nikki Fortunato Bas was taking two tickets for herself and a family member to the potential playoff game. The tickets’ declared value was 312.50 each, but tickets on StubHub were starting at $839 apiece Wednesday. Bas’ stated public purpose: “Reviewing the ability of a facility, its operator, or a local sports team to attract business and contribute to the local economy.”

That didn’t sit well with some who have scrutinized officials’ use of the free tickets for high end games and concerts.

“Everyone on the planet knows a council member is wanting to go to Game 6 for one reason — to watch the game, not to review the facility,” said Ralph Kanz, a resident and former member of Oakland’s Public Ethics Commission. “There is no public purpose in any elected official attending an event at the Coliseum and the Arena.”

Bas and her staff did not respond to questions Tuesday afternoon due to a City Council meeting. But Chief of Staff Miya Saika Chen said Wednesday morning that the posted form was a staff error and would be corrected.

“She did not plan on attending the game on game six,” Chen said. “She had expressed interest in tickets for a watch party for her family, and the person who processes the tickets posted the wrong form, which has happened before.”

Bas will be giving the tickets to community leaders and city workers, Chen said.

City and county officials’ use of free tickets to the arena and adjacent Oakland Coliseum has been an ongoing controversy.

This news organization’s October 2016 investigation found officials over three seasons claimed more than 7,000 tickets worth millions of dollars to Golden State Warriors’ games, often going themselves or giving them away to politically connected people. Since then, officials’ use of high-priced tickets, particularly to Warriors games, decreased but did not stop.

The Oakland Ethics Commission has investigated compliance with the ticket policy and the Alameda County Grand Jury a year ago said county officials used the free access to expensive games and concerts as a “perk.”

Bas wasn’t the only City Council member to state on forms that they were using the tickets for themselves and a family member as the Warriors make another historic run at an NBA title.

A posted form indicates Councilman Loren Taylor and a family member attended a “watch party” at the arena on Sunday showing the Warriors’ dramatic 109-104 Game 2 win over the Raptors in Toronto. His stated public purpose: “Oversight of facilities or events that may require City funding or support in the near future.” Taylor and his staff did not respond to questions about it.

Alameda County did not have disclosure forms more recent than March posted online Wednesday morning.

Last fall, after Mayor Libby Schaaf and Councilwoman Lynette Gibson McElhaney helped themselves to free tickets to attend Golden State Warriors’ playoff games and other marquee events, a city Ethics Commission investigator found no wrongdoing.

The commission staff determined the policies only required that the officials state on Fair Political Practices Commission forms that their attendance at the events was part of their official duties.

Critics say the policy and enforcement need to be tightened.

“My view is that the use of a ticket for this purpose would be a clear violation of the law,” said Stephen Shefler, a former Chief Assistant United States Attorney for Northern California as well as a former member of the ethic’s commission. “It is my view that the Public Ethics Commission response to this abuse was lame and has invited the continuation of such abuse.”

Schaaf this week has donated a ticket to Friday’s Warriors playoff game to benefit an education initiative. The ticket is being auctioned off, and Schaaf invited Raptors uberfan — and lately the Warriors’ most famous heckler — Drake, to bid on it.
