Deadline for Appeal

Hi Folks, We received the final decisiona on a very complicated industrial building we are pursuing certification for and EAp2 and IEQp1 were denied. We are appealing, but process has been going on for over 3 months now...it requires project updates and extra info from vendors that we are having a hard time to get on board. Is there a maximum deadline we have to submit documentation by? Any particular/special procedure we should take in this type of case? This building is part of a campus of 4 buildings and the 3 other buildings sucessfully achieved LEED certification. All 4 were built under the same contract and pursued LEED under the same process. Thanks!
