Once the very symbol of American industrial might, Detroit became the biggest U.S. city to file for bankruptcy Thursday, its finances ravaged and its neighborhoods hollowed out by a long, slow decline in population and auto manufacturing.

The filing, which had been feared for months, put the city on an uncertain course that could mean laying off municipal employees, selling off assets, raising fees and scaling back basic services such as trash collection and snow plowing, which have already been slashed.

"Only one feasible path offers a way out," Gov. Rick Snyder said in a letter approving the move.

Kevyn Orr, a bankruptcy expert hired by the state in March to stop Detroit's fiscal free-fall, made the Chapter 9 filing in federal bankruptcy court.

Michael Sweet, a bankruptcy attorney in Fox-Rothschild's San Francisco office, said the city would pay current employees. But "beyond that, all bets are off."

"They don't have to pay anyone they don't want to," Sweet said. "And no one can sue them."

Detroit lost a quarter-million residents between 2000 and 2010. A population that in the 1950s reached 1.8 million now struggles to stay above 700,000. Much of the middle-class and scores of businesses also have fled Detroit, taking their tax dollars with them.

Beginning in the late 1960s, auto companies began opening plants in other cities. Property values and tax revenue fell, and police couldn't control crime. Then the rise of autos imported from Japan started to cut the size of the U.S. auto industry.

In recent months, the city has relied on state-backed bond money to meet payroll for its 10,000 employees.

Orr was unable to persuade a host of creditors, unions and pension boards to take pennies on the dollar to help facilitate the city's massive financial restructuring. If the bankruptcy filing is approved, city assets could be liquidated to satisfy demands for payment.

Snyder determined earlier this year that Detroit was in a financial emergency and without a plan for improvement. He made it the largest U.S. city to fall under state oversight when a state loan board hired Orr. His letter was attached to Orr's bankruptcy filing.

"The citizens of Detroit need and deserve a clear road out of the cycle of ever-decreasing services," Snyder wrote. "The city's creditors, as well as its many dedicated public servants, deserve to know what promises the city can and will keep. The only way to do those things is to radically restructure the city and allow it to reinvent itself without the burden of impossible obligations."

A turnaround specialist, Orr represented automaker Chrysler LLC during its successful restructuring. He issued a warning early on in his 18-month tenure in Detroit that bankruptcy was a road he preferred to avoid.

He laid out his plans in June meetings with debt holders, in which his team warned there was a 50-50 chance of a bankruptcy filing. Some creditors were asked to take about 10 cents on the dollar of what the city owed them. Underfunded pension claims would have received less than the 10 cents on the dollar under that plan.

Orr's team of financial experts said that proposal was Detroit's one shot to permanently fix its fiscal problems. The team said Detroit was defaulting on about $2.5 billion in unsecured debt to "conserve cash" for police, fire and other services.

"Despite Mr. Orr's best efforts, he has been unable to reach a restructuring plan with the city's creditors," the governor wrote. "I therefore agree that the only feasible path to a stable and solid Detroit is to file for bankruptcy protection."

Detroit's budget deficit is believed to be more than $380 million. Orr has said long-term debt was more than $14 billion and could be between $17 billion and $20 billion.

Orr's decision to file now may have been influenced by lawsuits filed by some city workers and retirement systems to prevent Snyder from approving a bankruptcy request from the emergency manager, said Detroit-area turnaround specialist James McTevia.

They have argued that bankruptcy could change pension and retiree benefits, which are guaranteed under state law.

Orr has said federal bankruptcy laws trump state law in this matter.

A bankruptcy judge will stay all the litigation, McTevia said.

"One court will adjudicate all these," McTevia said.

Some are concerned that a bankrupt Detroit will cause businesses large and small to reconsider their operations in the city. But General Motors, which filed and emerged from a Chapter 11 bankruptcy, does not anticipate any impact to its daily operations, the automaker said Thursday in a statement.

"GM is proud to call Detroit home and today's bankruptcy declaration is a day that we and others hoped would not come," the statement said. "We believe, however, that today also can mark a clean start for the city.

Detroit has more than double the population of the Northern California community of Stockton, Calif., which until Detroit had been the largest U.S. city ever to file for bankruptcy when it did so in June 2012.

Before Detroit, the largest municipal bankruptcy filing had involved Jefferson County, Ala., which was more than $4 billion in debt when it filed in 2011. Another recent city to have filed for bankruptcy was San Bernardino, Calif., which took that route in August 2012 after learning it had a $46 million deficit.

About 640 Chapter 9 bankruptcies have been filed since Congress enacted a revised Municipal Bankruptcy Act in 1937.

Afam4eva: So, where are those automobile companies? I know Detroit has been stressed for some years now.

CFCfan:
Some auto makers relocated to other states like South Carolina.

Horus: This is what will hapen to America, Bankruptcy!

Afam4eva:
I need to readup on the history of the crisis and what informed them to leave. is it that Detroit was not giving them the enabling environment? I really fear for that city cos the crime rate will rise up. The only thing that has been giving Detroit a good name is the automobile industry.
