Teyacapan, seeing as you are not an admin, I'd like to know your reasoning behind this assumption. Currently, it is possible to stay a government without fulfilling all of the requirements (With the exception of activity and faction value, for which there are active checks against dissolution). Has there been an announcement I've missed pointing to this change, or are you simply speculating?
See Sim News "2009 SWC Dev Meeting - Day 3 (Posted by Seele on Year 10 Day 76)"
# Governments will require 40 members (increased from 30)
# Governments will need to have control of a Sector (in addition to 1 system and 3 planets)
# Raw Materials will not count towards capital for the creation of a government (but continue to be considered capital after creation) ”
If it wasn't required to avoid reversion then you could create as many goverments as you like from the same sector, that would make it a rather pointless requirement whilst failing to achieve the results it was added for.
