An anonymous reader writes: Frontier submitted a court filing last week supporting ATT's efforts to sue local governments in Louisville and Jefferson County, Kentucky to stop a new ordinance designed to give Google Fiber and similar companies access to utility poles. They're concerned the ordinances will spread to other states. Frontier's filing said, "the issues raised by the case may have important implications for Frontier's business and may impact the development of law in jurisdictions throughout the country where Frontier operates." The ordinance in Louisville lets companies like Google Fiber install wires even if ATT doesn't respond to requests or rejects requests to attach lines. Companies don't have to notify ATT when they want to move ATT's wires to make room for their own wires, assuming the work won't cause customer outages. ATT claims that the ordinance lets competitors "seize ATT's property." Frontier is urging the court to consider the nationwide implications of upholding Louisville's ordinance, saying Louisville's rule "is unprecedented" because "it drastically expands the rights of third parties to use privately owned utility poles, giving non-owners unfettered access to [a] utility's property without the [...] utility in some cases even having knowledge that such third-party intrusion on its facilities is occurring." Frontier said companies should be required to negotiation access with the owners if they didn't pay to install the utility poles. They urged the court to deny Louisville Metro's motion to dismiss ATT's complaint.
