The group, Stop SB48, which is named after the law, faced a Wednesday deadline to turn in just under 505,000 signatures to put the law on the ballot and give voters the opportunity to overturn it. In an e-mail, the group said, "We thank all of you that worked so hard to provide the hundreds of thousands of signatures received. In the end, 90 days was too short a time to accomplish such a large task."
They gave no precise number of how many signatures had been gathered. Backers ran the effort out of the offices of the Capitol Resource Institute, a socially conservative advocacy organization in Sacramento. The institute's executive director, Karen England, also was the leader of the referendum.
The group vows there will be another battle.
