No idea about the best legal route to take - not something I think about much.
Disappointed that there is no mention of expanding crofting areas. I think you could argue that there are places that were crofted in 1886 that aren't now and the land has slipped through the net (admittedly a long time ago). Also Aberdeenshire probably should have been included in the 1886 act due to the number of crofters there but the Lords (if I remember right) managed to get it excluded. Of course we live in a very different place from 140 years ago and expansion would look different to haw it did then but there must be some scope.
Also a bit shocked that they only managed to identify a tiny handful of unused crofts!!
And allowing owner occupiers to come out of the system is a sure way to kill the whole concept of crofting over a generation or 2.
