What is the test for determining whether a state official's conduct violates federal law or is wholly unauthorized by state law?

Under the second prong of the test, we ask whether the challenged conduct either violates federal law, or is wholly unauthorized by state law. If state officials act within the authority of state law and violate no federal rights, their interference with a plaintiff's legal rights is merely tortious, and is protected by the Eleventh Amendment.
