Backers of a proposed ballot initiative that sought to limit transgender bathroom use said Monday that they fell short of the signatures needed to qualify for the California ballot.

The group Privacy For All said that they had failed to gather the 365,880 valid signatures needed to get their measure on next year's November ballot. The measure sought to prohibit transgender people from using the public restrooms that correspond with their gender identity.

“There is a strong desire to keep bathrooms sex separate among a segment of California voters,” Gina Gleason, the group's spokesperson, said in a statement. “But much of California is still being introduced to the issue.”

“We are disappointed that this measure will not be on the 2016 ballot, but our efforts to protect privacy in bathrooms, locker rooms and showers will continue,” she added.

The group did not reveal how many signatures had been collected.
