In the canon law of the Catholic Church, a mission sui iuris (Latin: missio sui iuris, pl. missions sui iuris), also known as an independent mission, can be defined as: "an ecclesial structure erected from a previous territory, with explicit boundaries, under the care of a religious community or other diocese, responding to a missionary exigency and headed by a superior nominated by the Holy See, under the aegis of the Congregation for the Evangelization of Peoples."[1]
It is generally applied to an area with very few Catholics, or in areas where Christianity (in particular Roman Catholicism) is either outlawed or undergoing persecution, often desolate or remote, and ranks below an apostolic prefecture and an apostolic vicariate.
The clerical head is styled Ecclesiastical Superior and can be a regular cleric, titular or diocesan bishop, archbishop or even a cardinal, but if of episcopal rank often resides elsewhere (notably, in another diocese or the Vatican) in chief of his primary office there.
It can either be exempt (i.e. directly subject to the Holy See, like apostolic prefectures and apostolic vicariates), or suffragan of a Metropolitan Archbishop, hence part of his ecclesiastical province.
