I'm unsure what the purposes of in world meetings are at all with this option. While i understand that RA members are volunteers with limited time, it appears to me that having the option to defer a vote based on indecision doesn't serve our community well. Parliamentary procedure provides tools to allow more time to the group if it is not yet ready to vote, by allowing motions to be tabled from meeting to meeting. So long as issues are properly placed on a timely posted agenda, RA members should have time to discuss the issue with their constituents and do the research they wish to do. If they don't have time to do this, the proper solution is to table the motion.
I'm mostly concerned about three things.
One, our meetings are open and public. Anyone can read the transcripts and see what arguments are made for and against a motion, and how each representative responded to those arguments. By allowing a rep to defer their vote, you open the door to influence that is not readily apparent to the population. The possibility of even the appearance of opportunity for impropriety or undue influence should be avoided.
Two, proponents of legislation and the citizens who depend on them have the right to present their motions and hear the objections. Deferral defeats this. RA members need to do their homework before the vote is called, not after.
Three, while the 7 day vote has been used to accommodate the real life conflicts we all have with meetings, extending this to all members of the RA, whether absent or not, doesn't respect the work and time that RA members PRESENT at the meeting have put into their work. Imagine the situation where the vote is tied, and the final RA member chooses to defer his or her vote. The community is left hanging for 7 days, unable to move forward, or to resolve their disappointment.
I'd rather see the institution of a proxy system, and elimination of the seven day vote entirely.
