CN (TSX:CNR) (NYSE:CNI) commends the Surface Transportation Board's (STB) for its decision to freeze the merger review and order Union Pacific (UP) and Norfolk Southern (NS) to provide substantial additional information. This confirms what CN and many stakeholders have said all along: UP and NS still have not submitted a credible case to support their proposed merger. As the Board cautions, the Applicants' "supplemental filing" in July must present a "prima facie case," which means a case that meets the public interest standard at first glance. That burden belongs to UP and NS alone. It is not the job of public officials and stakeholders to fill the gaps in the Applicants' case. The process should not move forward before Applicants' "prima facie" showing has been made.
