Lawyers on behalf of death row prisoners claimed that the FDA has to stop importing “illegal” drugs in order to carry out the executions.

However the lawsuit alleges that the states have no right in importing suspect drug that has not been approved by the country’s drug authority. The lawyers claimed that the lawsuit was not a method of delaying the executions but they wanted to put an end to illegal drugs being used in such lawful sentences.
“It just seems wrong to allow these suspect goods into the country in violation of federal law just because they're used on prisoners rather than law-abiding citizens”, lead attorney Brad Berenson said.
