Under the Icelandic constitution, the President enjoys immunity from criminal prosecutions as long as the Parliament permits it.
Constitution of Iceland, Article 11, Paragraph 2
The President may not be prosecuted on a criminal charge except with the consent of Althingi.
Hypothetically, if the Icelandic Parliament (i.e. Althing) consent to the President being prosecuted, and the President is successfully convicted of a crime, what happens next?
Is the Icelandic President constitutionally required to resign if he/she is convicted of a crime (with the consent of the Althing)?
If the Icelandic President is convicted of a crime and refuses to resign, is it possible for him/her to remain as head of state while serving prison sentences?
Given that it seems to require only a simple majority vote for the Parliament to permit prosecution against President, would this mechanism function as an alternative form of impeachment and removal process with exceedingly low threshold?
