Public Service Company of New Mexico and two coal firms want a judge to stop the Santa Fe New Mexican from publishing documents the paper got accidentally from the Public Regulation Commission.
PNM says it will suffer "irreparable harm" if its confidential business information and trade secrets are published by the newspaper.
The utility wants to join in a lawsuit filed last week by the PRC seeking to block the newspaper from reporting on the information, which is related to the pending San Juan Generating Station case.
According to the lawsuit filed in state District Court, a New Mexican reporter filed a public records request for emails between PNM and PRC regulators and was inadvertently given email attachments that contained the confidential documents.
