“The Chrysler-Fiat alliance can now go forward, allowing Chrysler to re-emerge as a competitive and viable automaker,” the White House said in a statement applauding the decision.

Chrysler has passed swiftly through about five weeks of bankruptcy proceedings, partially as a result of the involvement of the Obama administration’s auto task force, which provided billions in financing and helped negotiate a deal with the company’s stakeholders.

Also Tuesday, a bankruptcy judge approved Chrysler’s plan to terminate 789 of its dealer franchises.

U.S. Judge Arthur Gonzalez’s order says the franchises, which represent about 25 percent of the company’s dealer base, can no longer act as authorized Chrysler, Dodge and Jeep dealers, effective immediately. A written ruling explaining the decision was expected to be filed later.

Earlier in the day, more than 25 attorneys representing hundreds of dealers from across the country argued in court that little would be gained by terminating the franchises, while Chrysler maintained that the move is a necessary part of its plan to cut costs and quickly emerge from Chapter 11.

Many of the dealers were trying to sell the last cars on their lots and preparing to shut their doors for good at the end of the day, while others planned to sell used cars or other brands after severing ties with Chrysler.

At Tuesday’s hearing, Chrysler attorneys also said the automaker would extend until Monday its program to help the affected dealers send any unsold vehicles to other dealers.

Under the agreement brokered in the days leading up to Chrysler’s April 30 Chapter 11 filing, Fiat will receive up to a 35 percent stake in the automaker, in exchange for sharing the technology Chrysler needs to create smaller, more fuel-efficient vehicles.

The United Auto Workers union will get a 55 percent stake that will be used to fund its retiree health care obligations, while the U.S. and Canadian governments will receive a combined 10 percent stake.

Meanwhile, the automaker’s secured debtholders would get $2 billion in cash, or about 29 cents on the dollar, for their combined $6.9 billion in debt. Some of the debtholders balked at the deal, saying as secured lenders they deserved more. The Indiana funds involved in the Supreme Court appeal hold about $42.5 million of Chrysler’s $6.9 billion in secured debt. They bought it in 2008 for 43 cents on the dollar.

The funds have also challenged the constitutionality of the Treasury Department’s use of money from the Troubled Asset Relief Program to supply Chrysler’s bankruptcy protection financing. They say the government did so without congressional authority.

Consumer groups and individuals with product-related lawsuits also contested a condition of the Chrysler sale that would release the company from product liability claims related to vehicles it sold before the asset sale to Fiat. Compensation for such claims would have to come from the parts of the company not being sold to Fiat. But those assets have limited value and it’s unlikely there will be anything to pay out.

“The Chrysler and GM bankruptcy plans will take away the the public’s right to hold these companies accountable for when their defective cars injure and kill people, which is the incentive that has forced such car companies to recall defective vehicles,” said Joanne Doroshow, of the Center for Justice & Democracy, in a statement.

Congress continues to scrutinize the Obama administration’s restructuring of Chrysler and GM. The Senate Banking Committee said it planned to call Ron Bloom, a senior adviser to the auto task force, and Edward Montgomery, who serves as the Obama administration’s director of recovery for auto communities and workers, to a hearing Wednesday.
