Yes, the Constitutional Charter of the Greek Orthodox Archdiocese of America, provides the Holy Eparchial [Provincial] Synod of America, the responsibility, after consultation with the Archdiocesan Council, to elect the Three Person Ballot (Triprosopo), which is fowarded to the Holy and Sacred Synod of Constantinople, which, as stated in the Charter, "according to the existing practice," elects the new metropolitan, from among those on the Three Person Ballot; however, the venerable Ecumenical Patriarchate is not restricted to that list, though the qualifications of a metropolitan specified in the Charter, limit the field of candidates. Never in the history of the GOAA, has the Patriarchate not elected a regional hierarch, (whether an auxiliary bishop, bishop, or metropolitan--depending on the period of the history), other than one of those on the Three Person Ballot. Further, although the language is not in the Charter, the practice is to elect the top vote getter, that's why some assume His Grace Bishop Savas is the selection.
In my recollection, I can't recall a ballot of a more qualified list of candidates. There have been occasions when the Eparchial Synod has included not well thought of clergy as the third choice, to help ensure the election of the top choice.
Bishop Savas has an excellent reputation and I've felt bad for him as he has been passed over for a metropolitan see more than once. Interesting how the Lord works, having been passed over, he's now up for the metropolitan of the metropolis in which I reside.
The Metropolis of Pittsburgh has been blessed with exceptional hierarchical service over the years, Bishop Gerasimos of Abydos, of Blessed Memory, served its predecessor entity, the Sixth Archdiocesan District, 1967-76 (+/-), and Metropolitan Maximos of Pittsburgh were exceptionally spiritual hierarchs, who served the Pittsburgh Metropolis so very well. Bishop Savas by all reports, will represent a continuation of that quality of hierarchical leadership.
