Can DCS control who reviews evidence in alleged Agg. Child Abuse case?

A young couple charged with this crime are unable to get a review of records without permission of DCS. Hours before and a few days after the charges, a different hospital found NO EVIDENCE of the injuries claimed in charges. 7 mo old and 2 siblings removed; father of two siblings already awarded primary custody, though criminal case against mom and stepdad pending. The court was asked to order review but is awaiting THE PARENTS finding someone qualified to do so before issuing order. Every doctor from Memphis to Vanderbilt in TN have refused to review the case; and DCS controls who does! This appears to leave no way to offer a defense. Attorneys (3) seem unable or unwilling to cut the red tape. There was NO abuse, but how can it be proved in these conditions? Help! - Is this your question? Add additional information
