Precedent is mixed on whether "spend 0 VCs" is an action (see CFJ 1444 vs. CFJ 1456). I also remember a stronger precedent with regard to fees that supports the caller's arguments, but I also haven't found it on a cursory look, may look deeper later. At this point, I do not rely on that aspect of the caller's argument to come to a decision of FALSE.
Are CFJs 1456, 1458, and 1459 what you're looking for?
