EUGENE – They were shuffled from foster home to foster home, physically abused and emotionally scarred. On Thursday, they spoke out on behalf of Oregon’s 4,500 children in the state’s foster care system in a federal courtroom in Eugene. The four-hour hearing represented the final step in settling a five-year class action lawsuit that advocacy groups for children brought against the Oregon Department of Human Services, which runs the state’s foster care system. Called a fairness hearing, the event gave current and former foster children an opportunity to testify about the proposed settlement.
