@Morningsider: thanks. I've no idea how valid the slant I've put on Management Rules is, but my logic was:
- Land Reform Act is very important and a lynchpin of Scottish policy.
- LRA specifically states that it can be altered by byelaws. It does not mention anything else.
- Byelaws are more 'official' than Management Rules, which come from an older Act.
- Therefore (with a massive leap of faith), Management Rules cannot restrict the LRA.
Having briefly looked around, Edinburgh's Management Rules aren't too bad. Aberdeen's are worse than Glasgow.
