What is the terminus of the AUMF?
<p>Does the <a href="https://en.wikipedia.org/wiki/Authorization_for_Use_of_Military_Force_Against_Terrorists" rel="nofollow noreferrer">AUMF</a>  authorization expire upon a certain condition or is it indefinite?  If not indefinite, at what point would it be terminated? </p>

<p>The operative language of the AUMF (from the link in the question) says:</p>

<blockquote>
  <p>That the President is authorized to use all necessary and appropriate
  force against <strong>those nations, organizations, or persons he determines
  planned, authorized, committed, or aided the terrorist attacks that
  occurred on September 11, 2001, or harbored such organizations or
  persons,</strong> in order to prevent any future acts of international
  terrorism against the United States by such nations, organizations or
  persons.</p>
</blockquote>

<p>So, it ends when all such nations, organization or persons no longer exist, or upon passage of a law repealing the AUMF. These nations or organizations would include the Taliban, and have been determined to include ISIS, so until both of those organizations are no more, the AUMF is arguably still in force.</p>
