We urge you to seriously engage with the significant issues raised by your Authority’s investment with Novalpina Capital and we look forward to your outstanding reply to our correspondence dated May 24, 2019.

18 June 2019 Dear Yana and Stephen Peel, We write to you in light of recent reporting indicating that you both own a stake in Novalpina Capital LLP.

Given Novalpina Capital’s recent acquisition of NSO Group and the obvious human rights concerns raised by NSO Group’s business practices, Citizen Lab’s Ronald Deibert seeks a response from the South Yorkshire Pensions Authority regarding how its investment in Novalpina is consistent with the Authority’s Policy and what measures were taken by the Authority to inform and educate pension fund contributors and members regarding NSO Group.

He provided oral comments to the committee which were, substantially, a truncated version of the brief he submitted. His oral comments are available to download, and what follows in this post is the actual brief which was submitted.

Without Novalpina Capital—or the parties that you hired to conduct due diligence—concluding that Citizen Lab reporting is flawed and providing a substantiated basis to prove such a finding, it remains the case that you are purchasing a company implicated in serious human rights abuses and have decided to simply ignore this fact.

The purpose of this letter is to alert Jefferies Financial Group and lending firms interested in the syndicated loan to the Citizen Lab’s structured, evidence-based research into the abuse of NSO Group spyware, as well as investigations and research conducted by organizations such as Amnesty International, security companies, and the security team at Google Inc.
