Monday’s U.S. Supreme Court decision in a closely watched securities case was the first class action in which newly appointed Justice Neil Gorsuch participated — and he didn’t disappoint.

Gorsuch joined the majority in the U.S. Supreme Court’s 5-4 decision in California Public Employees’ Retirement System v. ANZ Securities, in which the court ruled that the time period after which a defendant could no longer be sued by shareholders was a statute of repose that couldn’t be tolled.
