District Judge Stephen Yelenosky issued a temporary order sought by State Farm, which cited competitive reasons to keep private the information on homeowners rates.
The Dallas Morning News reported Friday that the judge did not rule out changing his mind if Insurance Commissioner Mike Geeslin formally decides that the twin rate filings are "insufficient" without the documents.
Company spokesman Kevin Davis says State Fair appreciates Thursday's court ruling and awaits the next steps.
Department officials declined comment until seeing the judge's written order.
Texas in 2003 ordered State Farm to cut rates by 12 percent and issue refunds.
The lawsuit, filed in March, is part of State Farm's refusal. The company says its rates are fair.
