call for opinion: reconsidering judgment

I once made a proposal which would have forced Calls for Judgment to fail if they were not enacted within a certain time limit. I self-failed it because some players were concerned that this allowed CfJs to be effectively vetoed by admins.

I now think a Call for Judgment should stop the game in the same way a Declaration of Victory does, with the exception that other Calls for Judgment could be posted in response to it. This would solve the problem of CfJs getting lost in the queue, as well as the problem of CfJs coming into effect after being made obsolete by gamestate changes.

The main problem is that the game would lose momentum after hitting a brick wall like this. Maybe players would think twice about invoking a CfJ with game-stopping effects? Or maybe a system could be devised to make it harder to invoke a CfJ?
