A citizens group says they won't continue the effort to get a referendum on the Kings arena deal, but this isn't the end for STOP.  

Opponents of the $477 million arena said they would continue to push for a vote on the revenue bond to fund the new facility. The group needed to collect 23,000 valid signatures in just 30 days. 

The Sacramento Taxpayers Opposed to Pork was advised by its attorney that the council decision could not be reversed by the referendum.

But STOP's Jim Cathcart told News10 the fight isn't over, for a very specific reason.

"What we're worried about is this city going bankrupt. We're worried about the services," Cathcart said. 

STOP leaders noting on the Facebook page that they plan to follow through on its lawsuit challenging the arena's Environmental Impact Report.

The city had no comment on the lawsuit, except that they remain focused on building the arena.
