Servant Cab is asking a Lancaster County judge to overturn a ruling by the Nebraska Public Service Commission that denied the company's request to expand its cab service.

The company, which until May was Lincoln's sole cab operator, had sought to serve Omaha and the rest of the state.

In a written decision Aug. 21, the PSC found that Servant Cab wasn't fit and able to provide expanded services, based on its history in Lincoln.

Its opinion came, in part, from evidence presented during earlier hearings on an Omaha cab company's application to serve Lincoln.

That application was approved after politicians, business people, liquor control officials and others testified about long wait times, high rates and poor customer service.

At a later hearing on Servant Cab's request, several Omaha residents, former cab drivers, business people and group leaders testified in support of the application because they were unhappy with the Omaha cab company’s service.

But in the end, the commission said Servant Cab did not have a plan for implementing and providing services across the state. Commissioners said if Servant Cab can't provide quality service in Lincoln, it can't serve the state.

This week, Servant Cab filed a petition seeking court review of the decision.

"This court should reverse the NPSC's decision and determine Servant Cab is fit, willing and able to provide the entire proposed service," attorney Gregory Barton wrote.

And that the service is required by public convenience and necessity, he said.

Alternatively, Barton asked the Lancaster County District Court to find, at a minimum, that Servant Cab was fit, willing and able to provide taxi service among points in Douglas, Sarpy and Washington counties and elsewhere in the state.

In addition to the Nebraska Public Service Commission, the suit names Happy Cab and other companies that protested Servant Cab's application.
