The South Dakota Supreme Court issued an opinion on Thursday, June 14, that state courts don't have jurisdiction over certification of the Keystone XL pipeline permit.
Pipeline opponents appealed the Public Utilities Commission's 2014 certfication of TransCanada's 2010 permit.
On appeal, a Sixth Circuit judge upheld the certification, and opponents appealed that decision.
Now the high court says neither the Sixth Circuit nor the Supreme Court has standing under state law to hear the appeal.
