A. The juvenile court in each county shall assign cases of children in out-of-home placement to a local board so that local boards are assigned an approximately equal number of children. In a case where a child resides in a county other than the resident county of his parents, the county of the child’s original jurisdiction shall maintain jurisdiction unless, for valid reasons, the judge of such county transfers jurisdiction. A list of the cases so assigned shall be sent to the local board and the supreme court. For each case so assigned, the juvenile court shall also send to the local board:
1. A copy of the case plan prepared by the division or agency.
2. A copy of the progress report or reports prepared by the division or agency pursuant to section 8-516, subsection E.
B. Notwithstanding subsection A of this section, the juvenile court in each county in its discretion, or on the request of a mediator from the child welfare mediation program, may assign appropriate cases of children in out-of-home placement to a local foster care review board for early review of the case plan within sixty days after the removal of the child from the child’s home.
