Back in the day, if someone was put on probation for an offence, rather than being disfellowshipped, if he re-offended whilst that probation was in force, disfellowshipping was automatic. Normally a probation lasted 12 months. After the probation was finished that was it. Privileges were restored. If he reoffended again, the earlier offence didn't count for anything. I know all this because I was involved in a matter where all of this occurred and the society were contacted so that everything was handled in line with current thinking.
I'm curious to learn of the procedure these days for someone who who has confessed to an offence, been placed on restrictions, but then has offended again whilst the restrictions are in force. Will he be automatically disfellowshipped?
