The issues on the operation of the Habitats Directive are:
(1) what standard of review the court should apply when considering whether there
has been a breach of the requirements of article 6(4) of the Habitats Directive;
(2) whether the Secretary of State breached the Habitats Directive in deciding that
the scheme for a second runway at Gatwick was not an alternative solution to the
scheme for the north-west runway at Heathrow on the basis that it would not
meet the “hub objective”;
(3) whether the Secretary of State breached the Habitats Directive in deciding to
exclude the Gatwick second runway scheme as an alternative solution to the
north-west runway scheme at Heathrow because it would potentially harm a
Special Area of Conservation (“SAC”) in which a priority species was present,

1a Changes to capex governance processes
4b Mandated design-and-build contracts
1b Separation of system planning and ops delivery
Master Plan approved on optimistic cost, schedule and scope
assumptions, with material risks (land, environmental mitigation)
insufficiently provisioned
Cost and schedule baselines required progressive re-forecasting as
execution realities emerged, rather than early corrective intervention
Risk materialisation (expropriation delays, DIA scope expansion)
addressed after approval, driving reactive cost and schedule escalation
Environmental Impact Declarations (DIAs) functioned as subsequent
regulatory gates, not constraints embedded continuously in delivery
planning
Judicial land expropriation processes operated outside the delivery
organisation’s control, with timelines incompatible with the approved
programme
Delivery executed through multiple major construction and assistance
