Whether any priest can absolve his subject from excommunication?

Objections

Objection 1 : It would seem that any priest can absolve his subject from excommunication. For the chains of sin are stronger than those of excommunication. But any priest can absolve his subject from sin. Therefore much more can he absolve him from excommunication.
Objection 2 : Further, if the cause is removed the effect is removed. But the cause of excommunication is a mortal sin. Therefore since any priest can absolve (his subject) from that mortal sin, he is able likewise to absolve him from the excommunication.
