This has gone on for so long that I wish they’d just get on with it. The lawyers must be rubbing their hands at the prospect of many more years of pointless argument until it eventually gets built where it could have been decades ago.
Nationally important infrastructure projects approved/initiated by the Government need some sort of expedited process; 30-40 years does no-one (excepting the above legal professionals) any favours and leads to huge expenditure on repeated inquiries with those directly affected being left in limbo. Far better to say: “airport/motorway/railway goes there, here’s your house value + 10% + relocation.” I’m not going to suggest that would leave everyone happy but it’s the least worst option for residents, given that these things normally get constructed despite anyones’ opinions, it being just a matter of timing...
