Ben Gaston analyses the constitutional implications of the Supreme Court’s ruling on HS2
Few projects have aroused such controversy and media furore as HS2, the government’s proposal for a high-speed rail link between London and the north. Equally sparse are judgments that threaten to alter the constitutional landscape that underpins our legal system.
