Indivior Prevails in Striking Representative Claims from UK Shareholder Action


Richmond, VA and Slough UK, December 5, 2023 – Indivior PLC (LSE/NASDAQ: INDV), a leading addiction treatment company, announced that the High Court of Justice of England and Wales has issued a judgment striking out representative claims by Wirral Council as administering authority of Merseyside Pension fund (“Wirral”) against Indivior under the Financial Services and Markets Act 2000 (“FSMA”).  Wirral’s suit was the first attempt by claimants to use representative proceedings for securities claims brought under Sections 90, 90A, and Schedule 10 of the FSMA. The proposed representative proceedings, if allowed, would permit a representative acting on behalf of unnamed claimants to attempt to prove a violation of law without proof of damages, in contrast to ordinary multi-party proceedings, which require proof of liability and damages for each claimant.


In September 2022, Wirral had filed a representative claim generally asserting that Indivior violated the FSMA by making misleading or dishonest statements regarding an alleged fraudulent scheme to switch the market for its SUBOXONE® branded products in published information relating to securities.  A similar claim was filed against Reckitt Benckiser. 


After hearing two days of argument in November 2023, the High Court on December 5 issued a judgment granting Indivior’s and Reckitt Benckiser’s applications to strike out the representative proceedings.  The Court specifically found that it “would be unfair and unjust, and contrary to the overriding objective, to allow the Representative Proceedings to oust the jurisdiction of the Court to case manage the claims from the start.” The Court’s judgment may be found here.


Wirral and other claimants separately had filed a multi-party action generally alleging the same claims, and levied similar allegations against Reckitt Benckiser Group PLC (“Reckitt Benckiser”) in separate actions. Pursuant to the Court’s judgment, the claim against Indivior may only proceed in those multi-party proceedings brought by the claimants named in those proceedings.  


Wirral may seek permission to appeal the Court’s judgment.
