On April 12, 2024, the U.S. Supreme Court issued an important decision in the case of Macquarie Infrastructure Corp. v. Moab Partners, L.P., No. 22-1165. Justice Sotomayor, writing for a unanimous Court, ruled that “pure omissions are not actionable under Rule 10b-5(b).” In other words, a pure omission (i.e., where a speaker says nothing) cannot support a private claim under Section 10(b) of the Securities Exchange Act of 1934 (the “Exchange Act”) and Rule 10b–5, even if such an omission could constitute a violation of Item 303 of Regulation S-K (“Item 303”).

On Wednesday 29 April the Outer House of the Court of Session in Edinburgh issued an opinion sanctioning two schemes of arrangement proposed by Premier Oil Plc and Premier Oil UK Limited (together, Premier Oil) (the Schemes). The Court addressed multiple grounds of challenge and did so without hearing live evidence, despite disputes of fact between the parties.
