Michigan's ban on assisted suicide took effect Tuesday, though voters in Dr. Jack Kevorkian's home state could repeal it when they head to the polls in two months.

Gov. John Engler signed the assisted suicide ban into law in July. The law makes assisting in a suicide a felony punishable by up to five years in prison and a $10,000 fine.However, a proposal on the Nov. 3 ballot would legalize physician-assisted suicide and automatically repeal the ban.

Detroit Cardinal Adam Maida has sent letters to more than 800 priests, calling for a get-out-the-vote campaign against the initiative.

Kevorkian, who has acknowledged attending more than 100 deaths, said he won't change his practice, no matter what law is on the books.

Politicians "don't do what's good for the people, so I don't think about it," Kevorkian said from his Detroit home Monday. "They're just there for their self-interest."

Michigan authorities have repeatedly failed to convict the 70-year-old retired pathologist of any crime in connection with the deaths.
