The Department of Children and Families appeals the reversal of the trial court's termination of the parental rights of F.L., the Mother, to her seventh child. The order of termination was based in part on a statute providing that a prior involuntary termination of rights to a sibling may serve as grounds for termination of rights to a current child. The primary issue is whether the statute unconstitutionally shifts the burden of proof from DCF to the parent by requiring the parent to show that her past conduct does not predict that the current child is at risk.
