JANE B. STRANCH, Circuit Judge. This is the fourth appeal in the case before this court. We summarized the claim in the last appeal: “Kentucky taxpayers sued the State of Kentucky and Sunrise Children’s Services, a religiously affiliated organization, alleging that Kentucky violated the Establishment Clause by paying Sunrise for religious services that the taxpayers allege Sunrise imposes on children in State custody.” Pedreira v. Sunrise Child.’s Servs., Inc., 826 F. App’x 480, 482 (6th Cir. 2020). After proceedings resumed, the taxpayers and Kentucky, without Sunrise, entered into a settlement agreement in which the taxpayers agreed to dismiss the suit in exchange for Kentucky’s agreement to make certain changes to its foster-care system, and jointly moved to dismiss the case with prejudice. The district court granted the motion, dismissed the case, and refused to review the settlement agreement. Sunrise appealed. We AFFIRM the decision below.
