| At issue is a 2012 law that gave Governor Dave 
				Heineman the authority to approve a route for TransCanada Corp's 
				proposed Canada-to-Texas project, which would carry tar sands 
				crude oil from Alberta to Texas.
 Siting issues are typically settled by the state's Public 
				Services Commission (PSC) but Heineman used the law to bless a 
				route for the 1,700-mile pipeline early last year.
 
 In February, a Nebraska court ruled that the governor had been 
				wrong to interrupt the normal sitting process.
 
 The hearing is due to start at 10 a.m. ET/1500 GMT (11 a.m. 
				EDT). Lawyers for the governor and a group of landowners will 
				each have about ten minutes to make their case before 
				potentially fielding questions from a panel of judges.
 
 A federal review of Keystone, led by the State Department, is on 
				hold pending the outcome of the Nebraska case.
 
 Environmentalists say the project must be rejected as part of a 
				broader campaign to fight climate change. Supporters say 
				Keystone would create jobs and spur the U.S. economy.
 
 The case is Thompson vs. Heineman, case number S-14-0158 in the 
				Nebraska Supreme Court.
