Class actions are of course much more a feature of the litigation scene in the U.S. than in the U.K, but things have been changing in recent years. The most significant initial change in direction toward collective actions in the U.K. was the adoption several years ago of “opt-out” actions in the U.K. Competition Appeal Tribunal proceedings. More recently, through its courts’ use of group litigation orders (GLOs), there has been a “surge in mass claims” in the U.K., according to a recent law memo. The result has been, according to the October 13, 2025, memo from the Skadden law firm, a “dramatic transformation” over the past decade in the U.K. of its “collective redress landscape.” The memo, which is entitled “Class Actions by the Backdoor? The Evolving Landscape of Group Litigation in the U.K,” can be found here.Continue Reading “Backdoor Class Actions”: Proliferating U.K. Collective Action Proceedings

In an interesting decision that explores the standard to be used in determining whether an earlier claim and a later claim are interrelated, the Delaware Supreme Court has affirmed a lower court ruling that a later filed opt-out action is related to a securities lawsuit earlier filed against First Solar, and therefore that the opt-out action is not covered under the D&O insurance program in place at the time the opt-out action was filed. Interestingly, the Supreme Court affirmed the lower court even though the appellate court held that the lower court had erroneously applied a “fundamentally identical” standard to the relatedness question rather than the relatedness standard defined by the policies. The Delaware Supreme Court’s March 16, 2022 opinion can be found here.

One of the more interesting developments in recent years has been the global rise of collective procedural mechanisms for aggrieved investors to seek redress from corporate parties for disclosure misrepresentations or omissions. In that vein, the recent revision of the securities laws of the People’s Republic of China are particularly interesting.

As discussed in a recent memo from AIG, presented in conjunction with the Shanghai-based JunHe law firm, the revised Chinese securities laws include among many other changes new provisions allowing for collective investor actions. According to the AIG memo, entitled “Securities Class Actions under the New Securities Law in China” (here), the revised law introduces “western-style class actions to China.”

The massive U.K. collective lawsuit against Mastercard will return to the Competition Appeal Tribunal for further proceedings as a result of the December 11, 2020 Judgement of the U.K. Supreme Court.
