The agri tenancy laws in Scotland are hugely complicated - I've read some of the stuff and it just made my head hurt.
There was a pretty shoddy piece of legislation passed in 2003 that seems to be the root of many of the issues but the current SG is working with the small number of farmers and landlords affected by the worst parts of it (including Mr Stoddard, as far as I can see) to reach individual solutions.
TBH, I'm in favour of land reform in Scotland but I fear that certain parties in the land reform movement have latched on to this particular case to push the "landowner bad / tenant good" agenda, ably supported by Mr Stoddart and the Scottish Tenant Farmers Association.
I've often thought that, when I'm old(er), I'd let out the land here to a young person who coudl work it. I won't do it unless I am protected from things like Absolute Right to Buy, which some in the STFA are stilll punting.
