A giant wind farm in California’s southern San Joaquin Valley is blowing gusts through a faraway federal court, with tens of millions of dollars potentially up in the air.

Some of the wind farm’s early investors want more than $200 million in additional subsidies that they say the federal government owes them. Obama administration officials, in turn, argue that the government paid $59 million too much. This week, a judge sharpened the administration’s side of the sword, agreeing that the U.S. can try to retrieve some of the taxpayer dollars paid.
