A federaljudge on April 21 blocked President Donald Trump's administration from enforcing a series of permitting policies that wind and solar‌energy industry groups say have stymied the development of new energy generation projects.

Chief U.S.District Judge Denise Casper in Boston issued a preliminary injunction,opens new tab sought by nine advocacy groups and industry trade associations that argued the administration had imposed unlawful roadblocks that have halted the development of wind and solar energy projects nationwide.

Thejudge said the plaintiffs were likely to succeed in showing the U.S.Department of Interior and other agencies adopted aseries of unlawful policies that had led to renewable energy developers canceling or delaying numerous wind and⁠solar projects nationwide.

Her ruling applies to members of the plaintiff organizations,which include RENEW Northeast and Alliance for Clean Energy NewYork.
