BOISE, Idaho (AP) — A lawsuit to force a group touting public schools chief Tom Luna's education overhaul to reveal still-secret financiers is back in state court. The group, Education Voters of Idaho, sought a shift to federal court, to help it fight Secretary of State Ben Ysursa's demands. But on Friday, Ysursa's attorney and the group's lawyer, Christ Troupis, signed papers agreeing to contest the matter in 4th District Court. Even so, a hearing on Ysursa's lawsuit that had been set for Friday at 1:30 p.m. has been postponed — and the original state judge removed from the case. Ysursa demands EVI disclose names of donors of more than $200,000 to broadcast ads promoting Luna's education changes before the Nov. 6 election. Troupis argues his group has the right to conceal donors' identities.
