Besides Sudan, have any other foreign countries argued before the Supreme Court of the United States?
<p>This term the Supreme Court ruled in the case <a href="https://www.supremecourt.gov/opinions/18pdf/16-1094_3d94.pdf" rel="nofollow noreferrer">Republic of Sudan v. Harrison</a>, in which a foreign country, namely Sudan, appeared before the Court to argue its case. Has this ever happened before?</p>

<p>Some examples:</p>

<ul>
<li><p><a href="https://supreme.justia.com/cases/federal/us/583/16-534/" rel="nofollow noreferrer"><em>Rubin v. Islamic Republic of Iran</em>, 583 US ___ (2018)</a>.</p></li>
<li><p><a href="https://supreme.justia.com/cases/federal/us/541/677/" rel="nofollow noreferrer"><em>Republic of Austria v. Altman,</em> 541 U.S. 677 (2004)</a></p></li>
<li><p><a href="https://supreme.justia.com/cases/federal/us/488/428/" rel="nofollow noreferrer"><em>Argentine Rep. v. Amerada Hess</em>, 488 U.S. 428 (1989)</a></p></li>
</ul>

<p>Note that the <a href="https://en.wikipedia.org/wiki/Foreign_Sovereign_Immunities_Act" rel="nofollow noreferrer">Foreign Sovereign Immunities Act</a> precludes a foreign country from being sued except under a narrow set of circumstances, so the range of civil cases will be limited.  In fact, in <em>Rubin v. Iran</em>, <em>Austria v. Altman</em>, and <em>Argentina v. Amerada Hess</em>, the main question was whether the FSIA was applicable and whether foreign countries could be sued under any other laws.  The <em>Sudan v. Harrison</em> case also touched on whether the conditions of the FSIA had been satsfied.</p>
