Exactly - it's so obvious isn't it? Sometimes I wonder - there are one or two analogous situations in the tax legislation I work with in my day job where, despite the government's stated agenda of fairness and clarity, there are long-standing ambiguities that could be addressed easily. You really have to ask what is the government's underlying motive in choosing not to tie up these loose ends. It looks to me like they are playing a "heads we win, tails you lose" game......
