The Living Church has examined a newly available English translation of the constitution and canons of the Southern Cone and sees impediments:
The situation seems especially complicated for the Diocese of San Joaquin which already approved the switch at its annual convention last December. Article two of the Southern Cone constitution limits membership in the province to dioceses “that exist or which may be formed in the Republics of Argentina, Bolivia, Chile, Paraguay, Peru and Uruguay and which voluntary declare themselves as integral diocesan members of the province.” Article four of the constitution requires that amendments “be submitted to the Anglican Consultative Council for consideration and then to each diocesan synod for approval.”
…
Another complication involves a Southern Cone canon on bishops which states they “should definitely retire by 68 years of age.” In a recent interview with TLC, Bishop John-David Schofield, who will turn 70 in October, said he had been previously been informed by the Presiding Bishop of the Southern Cone that the primate could waive the mandatory retirement age requirement on a year-to-year basis, but there is nothing in the constitution or canons to suggest the possibility of such an exception.
The Rev. Van McCalister, public relations officer for the Diocese of San Joaquin, said Bishop Schofield and the delegates to the diocesan convention operated in good faith.
“From our perspective we were invited to join unanimously by the House of Bishops of the Southern Cone,” he said. “We proceeded under the assumption that they had the authority to invite us and that they knew what they were doing.”
