Powerline in refuge

CHICAGO — The Seventh Circuit reversed a Wisconsin federal court’s injunction in favor of environmental advocates who say a proposed land swap’s powerline would run through a wildlife refuge on the Mississippi River; the injunction kept a utility company from doing any construction in the refuge. In this two-page ruling, the appellate panel says the district court made no finding that the environmentalists are likely to succeed on the merits, a necessary element to win a temporary injunction.
