(Adds GM statement, paragraph 8)
By Jonathan Stempel
NEW YORK, Dec 28 (Reuters) - General Motors Co on Thursday won a court ruling that could reduce the private litigation it faces over flawed vehicle ignition switches, which have been linked to 124 deaths and triggered a big recall.
U.S. District Judge Jesse Furman in Manhattan said the plaintiffs in two bellwether cases, involving accidents where airbags had deployed, could not introduce expert testimony to show how defective ignition switches might have played a role in the crashes.
The plaintiffs said their GM ignition switches might have rotated from "run" at the moment of impact to "accessory" or "off," causing the accidents or making them worse, and then back to "run" before the airbags deployed.
But Furman, who oversees multi-district litigation ("MDL") over the ignition switches, including 213 cases where airbags deployed, called the expert testimony "unreliable" because there was no evidence that "double switch rotation" occurred anywhere.
"The court recognizes that these conclusions may have a significant impact on a swath of cases now pending in the MDL and, thus, does not reach them lightly," the judge wrote.
Furman said his role is "to ensure the reliability and relevancy of expert testimony," and the opinions of the plaintiffs' experts "do not pass muster."
Bob Hilliard and Tamar Lusztig, two lawyers for the plaintiffs, did not immediately respond to requests for comment.
David Caldwell, a spokesman for Detroit-based GM, said the decision "reinforces our approach to contest cases that lack merit, while being open to fair resolution of cases that have more merit according to the facts and the law."
GM has paid more than $2.6 billion in penalties and settlements, including $900 million to settle a U.S. Department of Justice criminal case, over ignition switches that could cause engines to stall and prevent airbags from deploying.
The largest U.S. automaker has recalled more than 2.6 million vehicles over the defect since February 2014.
As of Nov. 30, there were 1,723 unresolved personal injury and wrongful death claims in the multi-district litigation, including the 213 where airbags deployed, a court filing shows. GM has also settled claims related to more than 1,700 claimants.
Thursday's decision dismissed claims by Vivian Garza, who was 19 when her Chevrolet Cobalt crashed on an icy highway in Alice, Texas, in February 2011.
It also dismissed claims by the son of Ruby Greenroad over the January 2013 crash of her 2007 Cobalt in the Houston area. Greenroad died at age 90 the following year.
