Call for Judgment: Leaving Alliances Fizzle

Patio11 (aka Patrick McKenzie) made the Proposal: Leaving Alliances.

It passed, but I was unable to enter it in the ruleset, as there was no rule specified for the text.

If this Call for Judgement passes, a rule shall be created with the name given by Patio11 in the comments to this CfJ, and the contents of Proposal: Leaving Alliances.

Would the assorted Warlords please render their verdict?

7-0 Reached Quorum. Enacted by Orson, October 19.
Inserted rule Leaving Alliances after rule Joining Alliances.
