Where laws permit, and in churches where such procedure is approved by a majority vote of the church members present at a properly called annual meeting, after receiving the written approval of the district superintendent, a church may elect one-half its church board members for two-year terms, or one-third of its church board members for three-year terms, in either case designating an equal number to be elected annually. When the church board is elected in this manner, the number of stewards and trustees chosen must comply with paragraphs 137 and 141.
