Final votes on Detroit’s plan to emerge from bankruptcy this fall were submitted on Friday by its creditors, including Detroit workers and retirees, and the city is expected to file a formal tally of those votes in federal court by July 21, the New York Times reported on Saturday. Some parties involved in the process said that updates they received during two months of voting suggested that the city’s plan, which includes cuts to pension benefits, was faring well among workers and retirees and that an unofficial running vote count in recent days appeared to favor the plan. City and state officials have said that they were cautiously optimistic. Still, some involved in the bankruptcy proceedings cautioned that no final tally had been provided and that a significant number of ballots had arrived as late as Friday at the California company that is conducting the count on the city’s behalf.
