Absolutely it works both ways. The reason I posted from the position I did is that too often in these discussions there is the assumption that the programmer understand the business well enough to make the call which in my experience is false.

Simple black and white declarations of right or wrong by either party are unlikely to result in an optimal solution to the whole problem.
