Cruzan v. Director, Missouri Department of Health, , was a United States Supreme Court case. It had to do with the right to die. Nancy Cruzan was a woman who was in a persistent vegetative state. Her family wanted to stop life support treatments so she could die. Hospital workers refused to do this without a court order. Eventually, the case made it to the Supreme Court. On June 25, 1990, the Court decided it was legal to require "clear and convincing evidence" that stopping life support is what a person would have wanted.
