We were taught by a member of the Presidency of the Seventy that an Area Seventy presides anywhere within the area where he lives and that he can also be assigned to a stake conference outside of his area, where he will preside at that conference by assignment from the President of the Quorum of the Twelve.johnshaw wrote:An area authority doesn't preside unless assigned by a member of the twelve. Technically the 70 ask must be assigned to preside, so sitting in the audience is correct for area and general 70
We were also taught that a General Authority Seventy presides anywhere in the world when an apostle is not present.
