A Chicago attorney wants to take her long-standing fight against the Illinois Department of Children and Family Services to the U.S. Supreme Court. Diane Redleaf says DCFS has treated parents unfairly when investigating cases of suspected child neglect or abuse. She filed a petition with the Supreme Court yesterday.

Redleaf says when DCFS suspects abuse in a family, it often gives the adults only two choices: either the suspected abuser must leave the house or the kids will be taken into temporary foster care.

REDLEAF: They can’t present those options without having evidence. They need actual evidence before they tell a parent that those are their options.

Redleaf says such options amount to threats and are a violation of parents’ rights. Last year, a federal court of appeals in Chicago ruled against Redleaf. The state child welfare agency would not comment on Redleaf’s filing with the Supreme Court.
