In the grand scheme of things, with all the confusion we have (new-sspx, indult, "Bishop" Pfeiffer, etc) this is not a big deal. People can get confirmed this way and then conditionally (if they want) when a real bishop is around. Some families can't get confirmation except once very 5-6 years (that's being optimistic). Desperate times call for desperate measures.
I’d say this only adds to the confusion.
Yes, it seems a bishop with ordinary jurisdiction can delegate a simple priest to perform confirmations in necessity.
The next question is: Can a bishop
without ordinary jurisdiction delegate a priest on the basis of supplied jurisdiction in necessity? +de Mallerais seemed to affirm it when he defended +Lazo’s confirmations on the basis of his certainly valid priesthood, despite being consecrated bishop in the NREC.
But here, we are confronted by a novel development: A priest taking it upon himself to perform confirmations (?) without any delegation at all (supplied or otherwise).
The possibility of such an argument and/or course of action never even occurred to me, and seems not too far from priests pretending to consecrate bishops, on the disputed pretext that the episcopal power is already latent within their priesthood/holy orders, and necessity “activates” it (ie., the basic argument of some conclavists).
Not sure if I will bother to study the matter further, but my “impression” is that this sounds shaky.
