Rule [G44]: "Generally, a rule violation by an Alliance that was directly caused by actions of the opposing Alliance will not be penalized. Rule [G28] is an exception to this rule."

The letter of this rule states [G28] as an exception, but the intent of that seems to be to prevent a defensive robot from blocking one in the key/alley by positioning itself so that it will get in the way, but not actually touching the offensive robot. I expect that in reality, only the robot initiating contact will be penalized — if this ever actually happens.
