After four years of watching Dr. Jack Kevorkian take part in dozens of suicides, the Michigan Legislature has passed a bill aimed at stopping him.

It approved a ban Thursday on assisted suicide, and Gov. John Engler said he will sign it. Effective Sept. 1, it would make assisted suicide a crime punishable by up to five years in prison and a $10,000 fine.Kevorkian reacted defiantly to the passage of the bill.

"Don't you know you cannot legislate morality? You cannot do that," he told the Oakland Press of Pontiac for a story Friday.
