Siemens Mobility Limited v High Speed Two (HS2) Limited

6 November 2023
[2023] EWHC 2768 (TCC)
High Court
Siemens lost a big court case against HS2. Siemens thought HS2 cheated when it gave a big train contract to a different company. The judge looked at everything and decided HS2 followed the rules fairly, even though there were some minor mistakes.

Key Facts

  • Siemens challenged HS2's procurement process for a £2.75 billion rolling stock contract awarded to a Bombardier/Hitachi joint venture (JV).
  • The procurement involved five stages of evaluation, with the JV deemed to meet the threshold despite a 'Shortfall Tender' in one stage.
  • Siemens alleged undisclosed criteria, manifest errors in scoring, unlawful change of control consent, flawed Stage 5 evaluation, and conflict of interest.
  • HS2 defended its process, citing thoroughness, margin of appreciation, and adherence to regulations.
