My letter's in the mail.
"ANY ONE, be he Catholic, non-Catholic Christian, or just non-Christian may file a suit and plead before a Catholic Ecclesiastical court or judge. Pursuant to Canon 1476 of the Code of Canon Law of 1983, it is no longer required for one to be baptized in order to sue in Ecclesiastical Court. In order to join the class-action lawsuit, your contact details are required for maintenance of the action, and for us to be able to keep you posted on the status of the case. "
