I regard the instituted ministries as applying to the person wherever they are located. The person is making a lifelong commitment to the ministry, but not to living is a particular location. Some extracts that support this:
Catechism of the Catholic Church, n 903: “Lay people who possess the required qualities can be admitted permanently to the ministries of lector and acolyte.”
Catechism of the Catholic Church, 1671: “Certain blessings have a lasting importance because they consecrate persons to God, or reserve objects and places for liturgical use. Among those blessings which are intended for persons - not to be confused with sacramental ordination - are the blessing of the abbott or abbess of a monastery, the consecration of virgins and widows, the rite of religious profession and the blessing of certain ministries of the Church (readers, acolytes, catechists, etc.).”
Ceremonial of Bishops, 790: “Unless they have already done so, candidates for ordination are to receive these ministries …”. The permanent nature of institution is clear, since it is not to performed on someone a second time.
Canon 1050, 3°: “for those to be promoted to the diaconate, certificates of the reception of baptism, of confirmation and of the ministries mentioned in Canon 1035.” [The Code of Canon Law - New Revised English Translation, (Harper Collins, London, 1997) 235.]
Canon 230.1: “Lay men whose age and talents meet the requirements prescribed by decree of the Bishops’ Conference, can be given the stable ministry of lector and of acolyte …”.
The Rite of Institution of Readers, n 5: “Then all stand, and the bishop, without his miter, invites the people to pray: Brothers and sisters, let us ask God our Father to bless these servants who have been chosen for the ministry of reader. Let us pray that they may be faithful to the work entrusted to them …”.
Pope Paul VI’s 1972 Motu Proprio Ministeria quaedam, n IV: “Two ministries, adapted to present-day needs, are to be preserved in the whole Latin Church, namely, those of reader and acolyte.” [Documents on the Liturgy (Liturgical Press, Minnesota, 1982) page 909, n 2929.] So the idea that a bishop can choose not to use Instituted Acolytes is not consistent with this (and with parts of Canon Law requiring that seminarians be instituted.)
The punishment of “loss of ecclesial office” is part of the Code of Canon Law. But a bishop who decides to give this punishment to a individual (of loss of the office of acolyte) needs to follow the proper procedures of a trial to do this.
