Texas authorities have dropped custody cases concerning more than 30 children from a polygamous group in west Texas.

A spokeswoman for the child welfare department says the state filed paperwork Thursday indicating it no longer needed court oversight of the 10 families involved. A judge agreed.

Spokeswoman Marleigh Meisner says the action doesn’t necessarily end the agency’s involvement with the families. But it does mean the agency believes the children can be safe without court oversight.

The state Supreme Court earlier forced Texas authorities to return more than 400 children swept into foster care from a polygamist group’s ranch. Many cases remain under review.
