Sounds to me like Cdl Dolan doesn’t want Sheen canonized. It doesn’t say that NY is reviving the effort to have him canonized there, simply that Dolan has forbidden Peoria (which has a relatively conservative bishop) to receive or have access to the remains for canonization purposes.
New York did send out a press release on Thursday indicating that if Peoria wants to call it quits, they would be willing to run the rest of the way in the cause. http://www.archny.org/news-events/news-press-releases/index.cfm?i=34110
It reminds me of the story of the Little Red Hen.
