This does not bode well for other cities. Via New York Times:
The judge, Steven W. Rhodes, dealt a major blow to the widely held belief that state laws preserve public pensions, and his ruling is likely to resonate in Chicago, Los Angeles, Philadelphia and many other American cities where the rising cost of pensions has been crowding out spending for public schools, police departments and other services. The judge made it clear that public employee pensions were not protected in a federal Chapter 9 bankruptcy, even though the Michigan Constitution expressly protects them. “Pension benefits are a contractual right and are not entitled to any heightened protection in a municipal bankruptcy,” he said. James E. Spiotto, a lawyer with the firm Chapman & Cutler in Chicago who specializes in municipal bankruptcy and was not involved in the case, said: “No bankruptcy court had ruled that before. It will be instructive.”
One union has already filed its intent to appeal the ruling and others are expected to follow.
