When my dad was twelve years old he was ordained an elder. He sat in a chair in the bishop’s office, a group of priesthood holders gathered around him and put their hands on his head, and the voice for the group stated my dad’s name and then confidently intoned, "…I confer upon you the Melchizedek Priesthood and ordain you to the office of elder." He then pronounced some brief words of counsel and blessing and closed in the customary way.
No one stopped the ordination, but someone was paying attention, so afterwards they huddled to determine how to proceed. My dad tells me that during the deliberations he was afraid that someone would suggest that they had to start over, that is, excommunicate and then rebaptize him and then ordain him to the proper office. I suppose you could call that the "ratchet" view of the priesthood.
Ultimately, it was decided that the ordination was an ultra vires act and therefore a nullity. They reformed the circle and made him a deacon.
