Verizon Communications is taking the New York Public Service Commission to court over the regulator’s ruling that $8 million in property tax refunds rebated to the phone company through a tax certiorari proceeding should be spent on improving Verizon’s service quality in the state.

Verizon wants to pocket the refunds of $1 million from New York City, $2 million from Oyster Bay, and $5 million from Hempstead for the benefit of the company and its investors, but regulators are insisting Verizon use the money to boost “capital expenditures to address purported service quality and network reliability concerns about its New York network.”

The PSC has been monitoring Verizon’s landline performance in the state since at least 2010 under its Verizon Service Quality Improvement Plan proceeding. Local officials and customers have filed complaints with the PSC about extremely long repair times, service outages, unreliable service, and sub-par line quality for several years, especially in downstate areas around New York City that have not yet been upgraded to Verizon’s FiOS fiber to the home service.

Regulators want those issues resolved, particularly after Verizon made it clear it has suspended its FiOS expansion outside of New York City. Customers with long-standing service issues are often offered a controversial wireless landline replacement called Voice Link, that has earned mixed reviews, instead of a permanent repair of their existing service.

Verizon calls the regulator’s demands arbitrary and unwarranted confiscation of its property.

“The commission did something it had never done before — it allowed Verizon to retain the refunds as it had in the past but this time also imposed a spending mandate which required Verizon to use the funds for a particular purpose,” the company claimed.

Verizon used the company’s long and successful track record convincing New York regulators that Verizon’s wireline networks have faced hard times as it bled landline customers, so it deserved regulatory and rate relief. Because the PSC recognized Verizon’s marketplace challenges when it “found that a lightened regulatory approach for traditional incumbent telephone carriers was warranted and necessary in order to level the playing field and enable them to remain viable providers in the future,” it is unwarranted to suddenly now demand the company spend its tax refund on network improvements, Verizon argued in its lawsuit.

In the past, Verizon added, the PSC allowed the phone company to keep its tax refund money for itself, even as it reduced spending on its infrastructure. The company claimed that to be “a proper regulatory response to the financial stress Verizon claims it is and will be under as it continues its transition to an increasingly competitive market.”

Earlier this year, the commission began to take a more formal look at the mounting service complaints it was receiving from Verizon customers and found troubling evidence Verizon might not be taking its copper landline network as seriously as it once did, especially in areas where FiOS upgrades have not been scheduled.

“…[T]here may be an unwillingness on the part of Verizon to compete to retain and adequately serve its regulated wireline customer base, and warrants further investigation into Verizon’s service quality processes and programs,” minutes from a March commission meeting state.
