Why automatic excommunication is not applied anymore, and how such a sanction was declared practically?
Not true at all.
Canon Law still has several provisions of automatic excommunication for:
invalid attempted ordination of women
physical attacks on the Pope
and other cases
Apostasy, heresy, and schism automatically excommunicate, even apart from Canon Law, by the very nature of the offense. So there has always been automatic excommunication, and there always will be, as long as these sins persist.
The other type of excommunication is juridicial excommunication, and that requires a Bishop or other person with proper authority to judge the particulars of a case, and to issue a sentence of excommunication according to that judgment.
