It could be a number of things. He could have left the Priesthood as many did in the 1970’s to get married. He could have caused grave scandal. Here is what the Code of canon law has to say…
Can. 696 §1. A member can also be dismissed for other causes provided that they are grave, external, imputable, and juridically proven such as: habitual neglect of the obligations of consecrated life; repeated violations of the sacred bonds; stubborn disobedience to the legitimate prescripts of superiors in a grave matter; grave scandal arising from the culpable behavior of the member; stubborn upholding or diffusion of doctrines condemned by the magisterium of the Church; public adherence to ideologies infected by materialism or atheism; the illegitimate absence mentioned in ⇒ can. 665, §2, lasting six months; other causes of similar gravity which the proper law of the institute may determine.
Can. 694 §1. A member must be held as ipso facto dismissed from an institute who:
1/ has defected notoriously from the Catholic faith;
2/ has contracted marriage or attempted it, even only civilly.
§2. In these cases, after the proofs have been collected, the major superior with the council is to issue without any delay a declaration of fact so that the dismissal is established juridically.
This canon is not about the priesthood. It is about religious life. There is a difference between being a consecrated religious and a priest.
A priest can be suspended and even excommunicated. He cannot be returned to his lay status. Once a priest always a priest.
A priest is dispensed from his priestly obligations. The term laicized is a misnomer. You cannot turn a cleric into a layman, because you cannot undo the sacrament of Holy Orders.
Any priest who receives a dispensation from the Church may perform any functions that any lay person in the Church can perform. They can be lectors, Eucharistic Ministers (they are not extraordinary because they are ordained deacons too), they can perform other ministries.
Many priests also have doctorates in theology. The academic degree has nothing to do with the Sacrament of Holy Orders. Therefore, they go from Fr. to Dr. In fact, you must have a PhD, DD, STD or some other doctorate to be ordained a bishop. You cannot be ordained a bishop if you are not a Doctor.
If a man is both a priest and a religioius he must seek a double dispensation. He must first be dispense from the vows that bind him to religious life. When that comes through, he is automatically a secular priest (as are all diocesan priests). After he is dispensed from religious life, the dispensation from the priesthood follows quickly if he has asked for both.
Some men who are religious and priests ask for a dispensation from religious life, but not from the priesthood. If the dispensation is approved, they become secular men and remain priests. To receive the dispensation from religious life a religioius priest must find a bishop who is willing to incardinate him into his diocese. Once the bishop agrees to do so, the religious superior must consent. After the religious superior consents, the priest begins a five-year probation living as a secular priest. After five-years, the bishop and the religious superior discuss whether the priest may remain outside of the religious order. If they agree, his vows are dispensed. He is a secular man for the rest of his life, but still a priest.
If either the bishop or the religious superior decided that the individual is does not have a vocation to be a secular man, he must return to the religious order where he was five years ago.
If he fails to return to the order, he is automatically excommunicated. There are no appeals. By Canon Law, the Superior General has the last word on whether a member of a religious order can leave or not. The Holy See or the Pope does not hear appeals except for Franciscans, Benedictines, Augustinians, Dominicans, Carmelites, Cistercians, Jesuits and Trinitarians, because these orders are exempt from the authority of any bishop. They answer directly to their Superior General, their Founder and the Pope.
But to answer the original question, a priest never returns to being a lay man. He is always a priest, even if he leaves in scandal, such as those who were accused of child abuse. If the ordination is valid, the Sacrament of Holy Orders is valid.
Priests who leave under such scandalous circumstances are suspended infefinitey. But can grant absolution in cases of life and death.
Priests who leave in good standing with the Church, can return to the life traditionally lived by most lay people. This is where the confusion of terms comes in. They live as lay people, but they are not lay. They are dispensed priests. A dispensed priest who is single or widowed can return to the active priesthood if a bishop will receive him and Rome approves.
All of these rules apply to deacons as well, becaue deacons are members of the clergy.
