A state court judge has temporarily blocked the Montgomery Advertiser from publishing information about a utility company’s plan for gas line safety, information obtained through an open records request.

Alagasco says the Distribution Integrity Management Plan, released to the newspaper by the Alabama Public Service Commission, contains proprietary and safety-related information that could jeopardize public safety, according to the Associated Press.

The Advertiser says the court ruling is a case of unconstitutional prior restraint. The Gannett-owned paper asked for the plan as part of an extensive pipe safety project by USA TODAY.

A hearing will take place Monday to determine whether the court order should stand.
