Aaron Streett, the attorney arguing on Halliburton’s behalf, kicked off his oral arguments with a direct plea that the Court overrule its 26-year precedent, Basic, Inc. v. Levinson.  In fact, he began by saying, “Basic, Inc. v. Levinson should be overruled because it was wrong when it was decided and it is even more clearly erroneous today.”  His point raises a critical question that the Court often faces:  what are the standards that the Justices should use in deciding whether to overturn a previous decision?  Justice Kagan addresses the question squarely in the clip below.  She states that overturning precedent is usually only appropriate when something fundamental has changed since the time when the previous case was decided.
