Well, I used a bit of poetic licence but there’s a case near me in the midlands in which the land owner has been forced to go to the high court (at his own expense) to get any chance of compensation. The tactics being used by hs2 and the Secretary of State are to frighten people into non-action. That is the leg of hs2 that is still (currently) going ahead.
But I’d eat my manky dog-walking hat if it’s the only example in the country.
