SIOUX FALLS, S.D. -

Petitions to stop the funding of a new city administration building are not valid due to whay may have been a copying issue.

Those wishing to start a petition can get the form online or have the city print them. In this case, the front sides of the petition were correct. However the back side was a completely different form, one that is used to petition state issues.

Sioux falls City Clerk Tom Greco says it didn't take long to detect an issue with the signatures.

“I think I might have been two or three petitions in and I noticed it on those, annotated it in my notes and continued the process checking all the randomly selected signatures,” Greco says.

Aside from the difference in forms, greco says that the signatures were valid.

Sioux Falls City Councilor Greg Neitzert says that the two forms look similar, but that the state petition is actually more strict than the city's. He believes that the petition could prevail if organizers take the signatures to court.

"The South Dakota state law is very protective of the citizens and the referendum of the process. And it says that petitions should not be discarded on a mere technicality. And I believe that it will have to be brought to court," Neitzert says.

Neitzert says this issue is now out of the city's hands and he doesn't blame officials for throwing out the signatures.

What happens next is up to petition organizer Bruce Danielson.

We reached out to him and he says he plans to take legal action of some kind, but is still working on those details.
