BOISE, Idaho (AP) — Idaho lawmakers are heading back to Boise to address failed legislation that has sent the state's child support enforcement and collection system into jeopardy.

Lawmakers will convene Monday for the special session. Lawmakers adjourned the regular session a little more than a month ago. They finished on the same day that nine lawmakers killed a child support enforcement bill, concerned that it would allow Islamic orders to trump state and federal laws.

State and federal officials have since warned that the killed bill jeopardizes negotiations on an international treaty and the state's ability to collect payments within its own borders. Gov. C.L. "Butch" Otter says the special session will cost about $36,000 a day. However, Otter and legislative leaders expect a deal will be passed in hours, not days.
