A federal appeals court has suspended a ruling ordering FEMA to resume housing payments to thousands of people displaced by Hurricane Katrina. The payments were to resume subsidies and subjected to a convoluted application process. But on Friday, an appeals court granted FEMA’s request to put the ruling on hold. Close to 4,200 Katrina families will have to wait until at least February to find out if their payments will return. The temporary housing program expires that same month unless extended by Congress or the White House.
