Verdict: The challenge of this ruling is to see whether Team TNT intentionally tried to mislead opponents by changing, or switching, the names of some of their cities, and whether they broke the "spirit of the game" and fairness pledge by doing so.
After a review of the evidence, RegentMan and myself have concluded the following:
Team TNT did not rename their cities in order to cause confusion or to mislead their opponents. In hindsight, we can now see what has happened, but at the time of the decision, this was not apparent. It was not their intention to cause all this; they wanted to switch city names around. This was a legal action they took, as rule 2.4 pertains to diplomacy (it is unclear). As such, the following is the 'verdict' and result of this investigation:
-Team TNT suffers no in or out of game punishment or warning for their actions.
-A new discussion about the 'spirit of the game' and rule 2.4 will be started with the purpose of preventing this from happening again. One aim of it will be to decide if cities' name changes will be documented or not.
-A formal notice to clear this all up: Team TNT's cities' names have been switched around.
End of thread. If you have an appeal to this rule, please PM RegentMan and myself. The aim of this is to please everyone while being fair and rule-abiding.
