SNAP, the Survivors' Network of those Abused by Priests, said as it released the list Wednesday that its accusations were based on media reports, legal filings and victims' statements.
A representative for one of the cardinals on list dismissed the group. The remaining cardinals or their representatives couldn't be immediately reached by CNN for comment Wednesday.
"I'm not going to respond to this group which has little to no credibility," said Joseph Zwelling, a spokesman for Cardinal Timothy Dolan of New York.
When asked about the SNAP list, the Rev. Federico Lombardi, a spokesman for the Vatican, told CNN: "We believe it is not up to SNAP to decide who comes to conclave and who is chosen. ... cardinals can decide themselves without asking SNAP for advice."
