I want to know the answer to the following question:
What case notably upheld the use of a method of lethal injection?
All the background I'm provided with is that "In the 2006 Hill v. McDonough case, however, the United States Supreme Court approved the use of Section 1983 as a vehicle for challenging a state's method of execution as cruel and unusual punishment in violation of the Eighth Amendment.". Is that enough to answer the question?
