CountMeOut.ie has recently updated their information regarding the formal defection process from the Catholic Church. If you are considering leaving the Catholic Church, please read their information at "Suspension of the Defection Process" ,
Essentially, the Catholic Church has modified Canon Law to remove all references to the formal act of defection. It does not appear to be acting on any new requests for this process, which was essentially an annotation in the baptismal record.
It's important to remind everyone that the defection was never equal to a Debaptism, as the Catholic church does not recognize the concept (at least not since it burned witches). This is also not equal to excommunication.
The Debaptist Church still contends that receiving a Debaptism triggers automatic excommunication and can also be considered an official rejection of the church, but again, this is not the same as a defection from the church.
