As far as I know, the review was completed back in May and reported at the MEC Meeting that month. This is from an update I received from my LEC after the MEC Meeting:

"Republic Air Holdings (RAH) Scope Issue
This is obviously a contentious issue for a majority of our pilots. During the MEC meeting, we had a very detailed briefing from our DALPA legal staff that explained the current scope language and how holding companies, such as RAH, fit into that language. A vigorous debate took place both in Delegate Committee and in plenary session. We accept the fact that RAH, as it is currently structured, does not violate the scope language in the PWA as currently written."
