Baxter v. Montana, is a Montana Supreme Court case, argued on September 2, 2009, and decided on December 31, 2009, that addressed the question of whether the state's constitution guaranteed terminally ill patients a right to lethal prescription medication from their physicians. The Montana Supreme Court sidestepped the question of if medical aid in dying is guaranteed under Montana State Constitution, but it instead ruled, on narrower grounds, that neither legal precedent nor the state's statute deem such assistance to be against public policy or illegal. Montana is one of nine states in which aid in dying is authorized. The others are California, Colorado, Hawaii, Maine, New Jersey, Oregon, Vermont, and Washington: it is authorized in the District of Columbia as well.
