A Texas state court of appeals ruled Thursday afternoon that the state of Texas had no right to seize more than 400 children from a polygamist ranch in Eldorado, in the western part of the state, because there was not sufficient proof that they were in immediate danger.

The ruling asserted that the state’s child protection agency acted hastily in removing the children from the Yearning for Zion ranch in April and did not make a reasonable effort “to ascertain if some measure short of removal and/or separation from parents would have eliminated the risk” of abuse toward the children of 48 mothers who filed the suit. The district court was ordered to remove its restraining order giving the state custody of those children, but it was not immediately clear how the hundreds of other children, now in foster care, would be affected.

At news conference in San Angelo, the closest city to Eldorado, a lawyer for the sect said it was not sure when the families would be reunited, and that the team was reviewing the next legal steps in the process.
