What reason could you possibly have to use non RFC 1918 space on a closed network? It's very bad practice - unfortunately I do see it done sometimes....
There are sometimes good reasons to do this, for instance to ensure uniqueness in the face of mergers and acquisitions.
How does that help? If you are renumbering due to a merger, couldn't you just agree on separate private space just as easily?
They don't renumber, they end up just double-NAT or triple-NAT betweem the merged units. I think one poor soul posted here that they had quintuple-NAT'ing going on due to a long string of mergers....
