Following up on this:
If the new slates take effect on Jan 1, and new arbs aren't necessarily considered active on current cases from 2007, what happens on Jan 1 to former arbs involved in still active cases? Especially where they voted to accept a particular case, voted at [[WP:RFAR/proposed decision]], etc.? Presumably, these cases will lack a quorum to make a decision if new arbs don't join?
