This was never a Nimby argument. Many thousands of people living along the route will not be able to sell their homes for some 15 years because their homes are blighted.
They should not have to bear the burden for this national project.
We hope now that proper arrangements are put in place by the Government for compensation for those who live by the proposed HS2 route to make it possible for them to move if and when they wish, in the same way that the rest of us can.
– Richard Stein, Leigh Day law firm who represented HS2AA
Judgment is being handed down by Mr Justice Ouseley at London's High Court. Whatever the judge decides, appeals against his decisions are almost certain to be taken to the Court of Appeal.
Key accusations include that the Government has unlawfully failed to undertake a strategic environmental assessment of the entire project before giving the go-ahead, or to arrange a consultation process "that allows informed responses on the true merits and demerits of the proposals".
There is also a dispute over the compensation arrangements being put in place for homeowners living near the HS2 line.
Some 172,000 properties within 1km of the first phase are reported to be affected by "a generalised blight" since the proposals were announced.
The High Court is to rule today on legal challenges to the Government's HS2 high-speed rail scheme.
Opponents are asking a judge in London to declare in a series of five cases that the multi-billion pound project is legally flawed and must be sent back for reconsideration.
The first phase of HS2 would see a high-speed railway line running through Tory heartlands from London to Birmingham.
The scheme has polarised opinion, with many residents' groups and local councils bitterly opposing it, but supporters point out the benefits of a reduction in journey times between the UK's two biggest cities.
If successful, the legal challenge could potentially delay the scheme for years.
A signalling problem between Wickford and Southminster has disrupted Greater Anglia services. A supplementary bus service is running on the whole Southminster branch with journey times extended by up to 30 minutes. There is currently no estimate for when a normal service will resume.
