LOS ANGELES: The widow of a man driving the Porsche that crashed and killed American actor Paul Walker cannot prove the car maker is responsible for the accident, a federal judge said.

There was not enough evidence in Kristine Rodas’ claims that her husband died because the Porsche Carrera GT he was driving lacked several key safety features, US District Judge Philip S Gutierrez ruled on April 4.

He said there was no evidence the Porsche’s suspension failed before the crash, as Rodas’ lawsuit claimed. She also had alleged the rare sports car lacked a crash cage and fuel cell.

“Plaintiff has provided no competent evidence that Roger Rodas’ death occurred as a result of any wrongdoing on the part of defendant,” Gutierrez wrote.

Walker was riding in the Carrera GT driven by his friend Roger when the car spun out of control, struck three trees and burst into flames in November 2013. Walker was on a break from filming the seventh instalment of the Fast & Furious franchise when he died.

The ruling has no bearing on two other cases against Porsche filed by Walker’s daughter and father, which are both pending in Los Angeles Superior Court.

Porsche has denied wrongdoing in the design, manufacture or marketing of the Carrera GT.

An investigation by the Los Angeles County Sheriff’s Department and California Highway Patrol concluded that unsafe speed, not mechanical problems, caused the crash. Investigators said the Porsche was going up to 94 mph (151 kph) when it crashed.

All the cases against Porsche contend the car was going much slower before it spun out of control. Kristine sued over the crash in May 2014. Her attorney, Mark Geragos, said on April 5 that the ruling will be appealed.
