Thanks, I was wondering why dependent actions and this isn't wholly
implausible.  However, I believe this runs afoul of the following from 
R1728:
       a) The rules explicitly authorize the performer to perform the
          action by a set of one or more of the following methods (N
          is 1 if not otherwise specified)
The problem is, that R1728(a) requires the rules as a whole to authorize
the performer to perform the action, and doesn't in itself "add" to that
explicit authority (if it did "add" it would be self-referentially 
meaningless).  So R2238 authorizes the dependent action, but it 
conflicts with R2140, which forbids it (note that authorization must be 
explicit; prohibition need not be - that tilt towards prohibition is a 
"for the good of the game" argument).  Therefore the net sum of "the 
rules" is that R2140 beats out R2238 due to power, and the action isn't 
authorized by the rules, so the test of R1728(a) fails.

I'm sure there have been other cases where one rule authorizes a
dependent action but another higher-power rule forbids it, and it's
that straightforward conflict that matters; R1728 doesn't "add" any 
authority as a power-3 rule if the test from (a) isn't met.
