GM ignition settlement unsettled: Trust dumps $10B deal announced last week

The claims stem from GM's 2014 recall of 2.6 million vehicles with defective ignition switches, including one linked to 124 deaths. The legal actions have since expanded to include millions of financial loss claims and hundreds of personal-injury and wrongful-death claims over a variety of alleged defects in millions of cars.

The settlement, first disclosed at a court hearing last week, would have called for the trust to accept $10 billion in claims, triggering a provision in GM's bankruptcy plan that could have forced it to pay $1 billion in stock to the trust to pay off the plaintiffs.

GM objected to the settlement.

Lawyers for the plaintiffs said in a court filing late on Wednesday they had learned of the "astonishing and improper" decision to jettison the settlement the day before a scheduled court hearing on the matter.

"Game isn't over," Steve Berman, a lawyer for the plaintiffs, said in an email on Thursday. "We had a deal, GM has knowingly interfered with our deal and we intend to take action against GM on various fronts."

He said the plaintiffs could bring a legal action against GM for interfering with the agreement and seek to seize the trust's assets.

According to a letter filed earlier on Wednesday by the trust and GM, the trust decided to drop the settlement after GM agreed to help pay for the trust to defend against the plaintiffs' claims.

"We are pleased with today's developments," GM said in a statement. "Now the focus can return to where it belongs, which is the merits of the plaintiffs' remaining claims. We will demonstrate that those claims lack merit."

Berman said in an interview last week that the settlement with the trust would have resolved about 11.9 million economic loss claims and between 400 and 500 personal injury and wrongful death claims.

About 2.4 million claims, involving vehicles sold after GM's bankruptcy, would have remained pending in district court, Berman said.
