The lawsuit was just filed today. The deadline was last Friday.
I'm just reading the lawsuit now at http://blackvelvetbrucelee.blogspot.com/2006/06/lawsuit-filed.html
My favorite part so far is paragraph 19 of Count I that says his feelings were hurt.
"I had no idea there was a deadline," Chapman said. "We had a fundraiser the night before and it never came up. No one in my campaign knew there was a deadline."
