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?
