The report is erroneous.
+Stobnicki was never even a priest of the SSPX (ie., +Williamson ordained him in 2017), much less a District Superior.
The report clearly confuses him for +Morgan.
I’m guessing the confusion on the total number of +Williamson bishops (mistakenly reported as 8, instead of 6), is because the latest EC discusses +Stobnicki and +Ballini, which someone thought were two more bishops, instead two of the six.
