The injunction order as granted can be found here. 

In the wide-ranging and comprehensive judgment, the Court reviewed the implications of Barking & Dagenham, the balance of ECHR Articles 10/11 and A1P1, and the status of a hybrid public authorities such as HS2 in the context of ECHR. The judgment will be of particular interest to practitioners due to the geographical scope of the injunction, as a 'persons unknown' injunction, and as to service.
 
HS2’s legal team for the application was led by Julie Dilcock (HS2 Legal) and Rob Shaw, Mary Barraclough, and Stephanie Owens (DLA Piper). They instructed Richard Kimblin KC, Michael Fry, Sioned Davies and Jonathan Welch.
