Isn't the treasurer just suppose to manage the finances, keep records of transactions, reporting on the finances and keeping the books up to snuff and not have the power to make decisions on where the money goes? Just an accountant and book keeper duties. If that's the case, and it's done honestly and to the letter of the law then I don't see any conflicts.
That brings back a memory. A company I worked for had a quarterly meeting company meeting with all the employees where they would talk about the "state of the union." Things like what we accomplished, what are the current challenges, where we are now, what is on the horizon, and where we want to go. Part of that all hands meeting was a presentation by the the CFO. He would give a summary of the finances and stuff. He made a side comment, jokingly, about a 2nd set of books. Either the CEO didn't like that joke or it struck too close for comfort and the CFO "resigned" a few months later to "move on to new endeavors."
