“A number of Catholic bishops and conferences of bishops have unequivocally rejected and publicly denounced CFC’s identification as a Catholic organization. For example, the United States Conference of Catholic Bishops (USCCB) and the Canadian Conference of Catholic Bishops have stated that CFC is not a Catholic organization and that it promotes positions contrary to Catholic teaching.”
…
“CFC is not a membership organization but an advocacy group. It relies upon paid employees and committed volunteer activists that it selectively recruits in various regions.”
…
“In 2007, CFC had a budget of $3 million, increased from $2.5 million annually in the years leading up to 2003. It has been supported largely by secular foundations such as the Ford Foundation, John D. and Catherine T. MacArthur Foundation, Rockefeller Foundation, and the Playboy Foundation.”

“Bishop Fabian Bruskewitz [namesake - Pope Saint Fabian, A.D. 200-250] of Lincoln, Nebraska, issued an interdict in March 1996 forbidding Catholics within his diocese from membership in 12 organizations including CFC. Bruskewitz stated that membership in any of these 12 groups ‘is always perilous to the Catholic Faith and most often is totally incompatible with the Catholic Faith.’
“Members of the diocese were given one month from the date of the interdict to remove themselves from participation in the named organizations or face automatic excommunication. Bruskewitz noted that heeding the ban on receiving the sacraments, which results from excommunication, ‘would be left to the person’s conscience.’”
Frances Kissling, CFC president at that time, said in response, “What we would advise people in that diocese to say is that ‘We consider ourselves to be Catholics in good faith, and we think you have rendered the wrong opinion,’ and to go about their lives as Catholics.”
Conclusion: The Vermont judge represented a volunteer or paid employee of Catholics for Choice, and the USCCB has made it clear that this is not a Catholic organization. The woman requested flyers be printed for a condemned group.
“We must keep in mind that the purpose of excommunication is to shock the sinner into repentance and conversion.” https://catholicstraightanswers.com/what-is-excommunication/
