After the accident, Uber quickly acknowledged that "a partner" had been involved in the accident and was equally quick to say that the partner wasn't working for the service when he struck the pedestrians, a statement intended to distance the company from liability. But Muzaffar was logged on to the Uber app and awaiting another customer, his attorney says, meaning that in essence he was engaged in company business and should be covered by the company's $1 million liability insurance policy.

Dolan contends in the suit filed today that Muzaffar was not only logged on to the app at the time of the accident, but was "viewing, monitoring and/or interacting with his wireless communications device/smartphone/GPS at or near the time of the collision." The complaint alleges that Uber's app requires drivers to violate the California law that seeks to address distracted driving by banning the manual operation of mobile phones, GPS devices and the like.

The suit also takes on Uber's suggestion that it has no liability because Muzaffar was not in active service at the time he struck Sophia Liu. The complaint notes that, like any other startup, the company's business model depends on attracting more users. To be able to deliver on its promise of prompt service, the suit say, the company needs a "significant number" of drivers available to provide rides. "Therefore," the suit says, "regardless of whether a DRIVER actually has a USER in their car, is on the way to a USER who has engaged the DRIVER through the APP, or simply is logged on to the APP as an available DRIVER, UBER, and/or RASIER LLC and/or RAISER-CA LLC and/or Does 1-10 and 21-30 derives an economic benefit from having DRIVERS registered on the service."

Dolan also represents the family of Jahi McMath, the brain-dead Oakland teenager who last month went to court to fight a hospital's attempt to remove her from a ventilator.
