CINCINNATI (AP) — A federal appeals court ruled Thursday that a judge went too far in blocking release of federal data about how prescription opioids were distributed.

A 6th U.S. Circuit Court of Appeals three-judge panel on Thursday vacated an order by Cleveland-based U.S. District Judge Dan Polster to keep the Drug Enforcement Administration database and other case information sealed from the public. The panel wrote that Polster should follow proper legal standards in deciding what information could be withheld and why it would be harmful to release it.

“However, the district court shall not enter a blanket wholesale ban on disclosure,” wrote Judge Eric L. Clay. He was joined by Judge Richard Allen Griffin. Judge Ralph B. Guy Jr. agreed with their ruling against sealing court filings, but not on the order protecting the drug database.

The judges heard arguments May 2 in Cincinnati from news media attorneys who said the information was important to understanding a national public health crisis.

“I’m very encouraged that the 6th Circuit is protecting … the public’s interest in knowing about how this opioid epidemic came to be,” attorney Karen Lefton, representing The Washington Post, said Thursday.

A U.S. government attorney had countered in court that making the data public could compromise ongoing DEA investigations. The Justice Department didn’t respond immediately Thursday to a request for comment.

Polster is overseeing more than 1,500 lawsuits filed by municipalities against companies that make and distribute prescription painkillers.  Guy wrote that the judge is trying to get the sides to negotiate a settlement and he didn’t see the harm in leaving Polster’s protective order in place for now.
