Gibson Dunn represented UBS in its successful appeal to the U.K.’s Supreme Court regarding proposed FX class-action proceedings filed in the Competition Appeal Tribunal. The Supreme Court unanimously allowed all the appellant banks’ grounds of appeal.
The Supreme Court’s judgment is an important restatement of the need for proper scrutiny of proposed collective proceedings at the certification stage. It makes clear that weak and unmeritorious claims should not be able to benefit from the procedural advantages that the opt-out procedure affords claimants.
The proceedings arose from two European Commission settlement decisions from May 2019 in respect of foreign exchange trading.
