Standing Rule B.1 provides:
The number of commissioners that each presbytery may elect for the 219th General Assembly (2010) is determined by the presbytery membership as of December, 2008. Presbyteries with up to 8,000 members (including minister members) will elect 1 minister and 1 elder; those with 8,001 to 16,000 members will elect 2 ministers and 2 elders, those with 16,001 – 24,000 members will elect 3 ministers and 3 elders, etc.
This chart shows the 2008 membership figures for each presbytery (as reported to the Office of the General Assembly), and the number of commissioners that each presbytery is eligible to elect.
Twenty presbyteries will elect 2 fewer commissioners than they had for the 2008 assembly; please confirm the number your presbytery may elect early in your process.
