contract-law licensing liability
Liability limited to 1 euro
<p>Often I see a disclaimer to negate any damages caused by software. But I found <a href="https://www.pgadmin.org/licence.php" rel="nofollow noreferrer">https://www.pgadmin.org/licence.php</a> which has the last line that says liability should be limited to 1 euro. Is there a reason why a liability cannot be fully negated?</p>

<blockquote>
  <p>The Artistic Licence</p>
  
  <p>BY INSTALLING OR DISTRIBUTING PGADMIN AND RELATED SOFTWARE, YOU AGREE
  WITH THE FOLLOWING DISCLAIMER:</p>
  
  <p>PGADMIN AND RELATED SOFTWARE IS PROVIDED WITHOUT GUARANTEE OR WARRANTY
  OF ANY KIND. TO THE FULLEST EXTENT ALLOWED BY LAW YOU AGREE THAT THE
  PGADMIN DEVELOPMENT TEAM MEMBERS, CONTRIBUTERS OR DISTRIBUTORS OF THE
  SOFTWARE CANNOT AND WILL NOT BE HELD LIABLE FOR ANY DIRECT OR INDIRECT
  DAMAGE OR LOSSES CAUSED WHOLLY OR IN PART BY THE SOFTWARE.</p>
  
  <p>IN COUNTRIES WHERE THE ABSENCE OF LIABILITY MAY NOT EXIST OR BE
  RESTRICTED BY LAW, PGADMIN DEVELOPMENT TEAM MEMBERS, CONTRIBUTORS AND
  DISTRIBUTORS LIABILITY SHALL BE LIMITED TO ONE EURO.</p>
</blockquote>

<p>It says so:</p>

<blockquote>
  <p>IN COUNTRIES WHERE THE ABSENCE OF LIABILITY MAY NOT EXIST OR BE RESTRICTED BY LAW</p>
</blockquote>

<p>In many countries it is unlawful to contractually eliminate liability. However, in most of those it would also be illegal to try to limit it to a notional amount.</p>
