Am inclined to support this proposal.
Because this arose locally, the timing of a resignation could be a factor that warrants some flexibility.
For example, what if an officer or at large member tenders an irrevocable resignation letter effective in four months?
Should that option be afforded an officer or member?
What if the need to resign arises 30 days before a convention? Is it really necessary to fill a vacancy before the convention? (See Articles 6.8 and 7.7).
And conversely, what if there is some gamesmanship with a timed resignation? Should the LNC be empowered to vote that down (e.g., "no, your resignation needs to be effective in a shorter period of time")?
