In the OCA Parish that I belong to, we follow the Statute of the OCA that has, IMHO, exemplary provisions on this matter. Here is a teaser:
"Section 8. The Parish Council
1. The parish meeting shall elect a Parish Council to assist the Rector in the administration of the parish and to execute the decisions of the parish meeting. The Parish Council shall consist of as many officers and members as provided for in the parish by-laws. Their mode of election and their terms of office shall also be determined by the by-laws regularly adopted.
2. All officers and members of the Parish Council shall, after their election at the parish meeting and approval of the Diocesan Authority, be duly installed by the Rector, making a solemn commitment to uphold their office.
3. The Orthodox Church teaches that there should be an active cooperation between clergy and laity on all levels of Church life. And since the Parish Council is the main parish organ of such cooperation, none of its meetings may be held without the knowledge and blessing of the Rector who, as the head of the parish, must take part in the discussion and solution of all parish affairs. While the priest is the head of the parish, he does not have to be Chairman of meetings. Laymen may be Chairmen. The minutes of all meetings of the Parish Council shall be signed by the Rector and the senior elected officer of the parish. In the case of the Rector’s disagreement with one or several decisions of the Parish Council, his motivated opinion shall be recorded in the minutes and the matter referred to the parish meeting.
4. The Parish Council shall be responsible not only for the spiritual and material needs of the parish, but also for the parish’s unity and connection with the Diocese and the Church, for each parish is called to be a living cell and a member of the Body of Christ, and each carries responsibility for the whole Church."
The rest of the Section is in the same vein and may be read at http://oca.org/statute/article-x
