Does an attorney in Germany have to prosecute own relatives
<p>In German penal law, does an attorney (Staatsanwalt) have to prosecute own relatives (parents children, siblings, etc.)?
If no, by what law (I could not find any that would provide them with that right)?
If so, are there some case examples?</p>

<p>Attorneys are normal officials (Beamte), so the laws about officials apply to them. So e.g. for North Rhine-Westphalia (there are similar laws in the other states) <a href="https://recht.nrw.de/lmi/owa/br_bes_detail?sg=0&amp;menu=1&amp;bes_id=34806&amp;anw_nr=2&amp;aufgehoben=N&amp;det_id=405157" rel="nofollow noreferrer">§ 47 Gesetz über die Beamtinnen und Beamten des Landes Nordrhein-Westfalen</a> (Law about officials of the state North Rhine-Westphalia):</p>

<blockquote>
  <p>(1) Beamtinnen und Beamte sind von Amtshandlungen zu befreien, die sich gegen sie selbst oder Angehörige richten würden, zu deren Gunsten ihnen wegen familienrechtlicher Beziehungen im Strafverfahren das Zeugnisverweigerungsrecht zusteht.</p>
  
  <p>(1) Officials are to excuse of official actions, that are against them or their relatives, if they have the right to refuse to testify against them in criminal proceedings.</p>
  
  <p>(my bad translation)</p>
</blockquote>

<p>These relatives are according to <a href="http://www.gesetze-im-internet.de/stpo/__52.html" rel="nofollow noreferrer">§ 52 Strafprozessordnung</a> (Code of criminal procedure): fiancée, spouse (even ex-spouse) and any "person who is or was lineally related or related by marriage, collaterally related to the third degree or related by marriage to the second degree."</p>

<p>So attorneys do not have to prosecute their relatives.</p>

<p>In some (but not all) German states this is not only a right of the attorney, but they are forbidden to perform official actions in processes against their relatives. So e.g. in Saxony-Anhalt, <a href="http://www.lexsoft.de/cgi-bin/lexsoft/justizportal_nrw.cgi?xid=174693,15" rel="nofollow noreferrer">§ 14 I n. 2, 3 Ausführungsgesetz des Landes Sachsen-Anhalt zum Gerichtsverfassungsgesetz</a> (Law of the state Saxony-Anhalt to implement the Courts Constitution Act)</p>

<blockquote>
  <p>Ein Beamter, der das Amt der Staatsanwaltschaft ausübt, darf keine Amtshandlungen vornehmen, wenn er</p>
  
  <p>[...]</p>
  
  <ol start="2">
  <li><p>Ehegatte oder Eingetragener Lebenspartner, Vormund oder Betreuer des Beschuldigten oder Verletzten oder einer Partei ist oder gewesen ist;</p></li>
  <li><p>mit dem Beschuldigten, dem Verletzten oder einer Partei in gerader Linie verwandt oder verschwägert, in der Seitenlinie bis zum dritten Grade verwandt oder bis zum zweiten Grade verschwägert ist oder war;</p></li>
  </ol>
  
  <p>[...]</p>
  
  <p>An official, who exercises the office of a prosecutor, is not allowed to perform official actions, if he is or was</p>
  
  <p>[...]</p>
  
  <ol start="2">
  <li><p>the spouse or registered life partner, guardian or legal curator of the accused or of the injured or of a party;</p></li>
  <li><p>lineally related or related by marriage, collaterally related to the third degree or related by marriage to the second degree to the accused or to the injured or to a party;</p></li>
  </ol>
  
  <p>[...]</p>
