The U.S. Supreme Court’s 2017-2018 term, which commences on Monday, is no exception to this recent trend. There are three important securities cases on the Court’s docket for the upcoming term, and these cases could have, both individually and collectively, a significant impact on many securities law cases and on securities litigation in general.
The U.S. Supreme Court has agreed to take up a case that will address a recurring issue that has arisen in the securities class action litigation arena – that is, whether or not the alleged failure to make a disclosure required by
