The Kampala Amendments, Germany, and the White Helmets
<p>(as a legal question, I understand that some follow only one of the two main narratives currently running on world events!)</p>

<p><a href="https://web.archive.org/web/20110616100534/http://www.icc-cpi.int/iccdocs/asp_docs/Resolutions/RC-Res.6-ENG.pdf" rel="nofollow noreferrer">Annex I 2.2(g)</a> states that:</p>

<blockquote>
  <p>(g) The sending by or on behalf of a State of armed bands, groups,
  irregulars or mercenaries, which carry out acts of armed force against
  another State of such gravity as to amount to the acts listed above,
  or its substantial involvement therein.</p>
</blockquote>

<p>counts as aggression. (not that this was necessary since Nicaragua vs USA (1986) said the same thing). </p>

<p>Now I understand that if the armed action is extraterritorial to the funding state, as is the case with Germany's (et al's - but they never ratified the amendments) financing, only a state can bring a claim. </p>

<p>However, if members of this group get resettled within Germany, can a private German citizen bring the same claim against their government? </p>

<p>Or would it be necessary for any member of a group that violated the above quote to first carry out acts equivalent to state force within Germany itself? </p>

<p><a href="https://en.wikipedia.org/wiki/United_Nations_General_Assembly_Resolution_3314" rel="nofollow noreferrer">UN Resolution 3314</a> is not binding, and <a href="http://hrlibrary.umn.edu/instree/GAres3314.html" rel="nofollow noreferrer">Art 3(g)</a> is "just a recommendation". Whether or not A can bring a claim against B has to be determined by the laws of a country with jurisdiction or, possibly, an international law. The summary is that an individual has no standing to pursue the matter in ICC; I don't know whether individual A could bring a claim against B in Germany under German law.</p>

<p>The crime of aggression is defined by an <a href="https://asp.icc-cpi.int/iccdocs/asp_docs/RC2010/AMENDMENTS/CN.651.2010-ENG-CoA.pdf" rel="nofollow noreferrer">amendment in 2010</a> (the Kampala Amendment) to the <a href="https://en.wikipedia.org/wiki/Rome_Statute_of_the_International_Criminal_Court" rel="nofollow noreferrer">Rome Statute of the ICC</a>. As it happens, the amendment was 
<a href="https://treaties.un.org/Pages/ViewDetails.aspx?src=TREATY&amp;mtdsg_no=XVIII-10-b&amp;chapter=18&amp;lang=en" rel="nofollow noreferrer">accepted</a> (not ratified) by Germany. The crime of aggression is defined in the amendment as</p>

<blockquote>
  <p>the  planning,   preparation,  initiation  or  execution,  by  a<br>
  person  in  a  position  effectively  to  exercise   control  over  or
  to  direct  the  political  or  military  action  of  a  State,  of 
  an  act  of   aggression which, by its character, gravity and scale,
  constitutes a manifest violation  of the Charter of the United Nations</p>
</blockquote>

<p>Then there is a long list of conditions defining "act of aggression". The Rome Statute has <a href="https://en.wikipedia.org/wiki/Amendments_to_the_Rome_Statute_of_the_International_Criminal_Court" rel="nofollow noreferrer">numerous amendments</a>, with the definition of aggression being the only relevant one that is in force. Now we can look at <a href="http://legal.un.org/icc/statute/99_corr/cstatute.htm" rel="nofollow noreferrer">the statute itself</a> (the originally passed statute). As a preliminary, "The Court has jurisdiction only with respect to crimes committed after the entry into force of this Statute" (Art.11) Under Art. 12, if a state becomes a party to the statute then they are subject to the court's jurisdiction w.r.t. the claim. Germany could then request an investigation by the prosecutor (and could be investigated), under Art. 14:</p>

<blockquote>
  <p>A State Party may refer to the Prosecutor a situation in which one or
  more crimes within the jurisdiction of the Court appear to have been
  committed requesting the Prosecutor to investigate the situation for
  the purpose of determining whether one or more specific persons should
  be charged with the commission of such crimes.</p>
</blockquote>

<p>There is no limitation to the effect that the state party has to have been in any way an aggrieved party. Art 13 gives the court jurisdiction if</p>

<blockquote>
  <p>A situation in which one or more of such crimes appears to have been
  committed is referred to the Prosecutor by a State Party in accordance
  with article 14...A situation in which one or more of such crimes
  appears to have been committed is referred to the Prosecutor by the
  Security Council acting under Chapter VII of the Charter of the United
  Nations or...The Prosecutor has initiated an investigation in respect
  of such a crime in accordance with article 15</p>
</blockquote>

<p>So the bottom line is that Germany can request prosecution, or the Security Council can, or the Prosecutor can <em>sua sponte</em> prosecute an alleged crime. But Mr. Jones has no standing in ICC for alleged aggression.</p>

<p>An alternative is that maybe Mr. Jones can bring a claim against an aggressor (let us say, the Elbonian Empire) under German law, but that would be orthogonal to questions about the Rome Statute.</p>
