Incorrect.
Only those directly complicit in an actual abortion are excommunicated automatically. (Canon 1397)
Wrong Canon Arthur.
Can. 1397 One who commits murder, or who by force or by fraud abducts, imprisons, mutilates or gravely wounds a person, is to be punished, according to the gravity of the offence, with the deprivations and prohibitions mentioned in can. 1336. In the case of the murder of one of those persons mentioned in can. 1370, the offender is punished with the penalties there prescribed.
Can. 1398 A person who actually procures an abortion incurs a latae sententiae excommunication.
2272 Formal cooperation in an abortion constitutes a grave offense. The Church attaches the canonical penalty of excommunication to this crime against human life. "A person who procures a completed abortion incurs excommunication latae sententiae,"76 "by the very commission of the offense,"77 and subject to the conditions provided by Canon Law.78 The Church does not thereby intend to restrict the scope of mercy. Rather, she makes clear the gravity of the crime committed, the irreparable harm done to the innocent who is put to death, as well as to the parents and the whole of society.
Can. 1314 A penalty is for the most part ferendae sententiae, that is, not binding upon the offender until it has been imposed. It is, however, latae sententiae, so that it is incurred automatically upon the commission of an offence, if a law or precept expressly lays this down.
Can. 1364 §1 An apostate from the faith, a heretic or a schismatic incurs a latae sententiae excommunication, without prejudice to the provision of Can. 194 §1, n. 2; a cleric, moreover, may be punished with the penalties mentioned in Can. 1336 §1, nn. 1, 2 and 3.
Dolan, sorry.
