It's an interesting question. It is easy to check when a position is unreachable, sometimes.
For instance a white king on H8 and black Rooks on A7, A8 (unless I'm mistaken).
It almost seems as if it is easier to find a position that is guilty (when it is), than to check that a position has a perfect record (check that it is legal).
