Caller's Arguments:

Consider a CFJ such as CFJ 2069, which asked if a particular message
contained at least one game-relevant action.

Either the contents of this message affect the outcome of a CFJ such as
2069, or they don't. In the case that the contents do affect the
outcome, this means that the publishing of the message itself was a
game-relevant action, because it affected the outcome of the CFJ;
therefore, whatever the contents of the message, the CFJ is going to be
ruled FALSE (i.e. TRUE that there is a game-relevant action), and
therefore the contents of the message do not affect the outcome of the
CFJ, as it would have the same outcome whatever the contents of the
message. This is a contradiction.

If the contents of the message don't affect the outcome of the CFJ, this
must be because the CFJ would always rule that there is a game-relevant
action (because clearly it is possible to file a message with a
game-relevant action in). In the case where there are no actions in the
message other than its publication, this is also, obviously, a

Therefore, both TRUE and FALSE lead to a contradiction, thus this CFJ
must be judged UNDECIDABLE. (Note that this does not lead to a Win by
Paradox, as it isn't about the permissibility or legality of a
rule-defined action.)


Judge Wooble's Arguments:

I judge FALSE.  The publication of a message may itself be a
game-relevant action, but a message so published doesn't necessarily
"contain" any action.

(For that matter, I'm not sure it makes sense to say a message
"contains an action" at all; at best a message might contain an
*announcement* that the publisher is performing some action. Whether
these are equivalent is irrelevant to the outcome of this CFJ; a blank
message contains nothing at all, whether the publication of that
message constitutes a game-relevant action or not.)
