An Argentinian judge on Wednesday initiated the investigation process into Saudi Arabia’s Crown Prince Mohammed bin Salman while he is in Argentina for the G-20 Summit.

Federal Judge Ariel Lijo agreed to the Human Rights Watch’s request to determine whether Yemeni and Saudi legal authorities were investigating the prince for crimes against humanity, including his alleged involvement in the murder of Saudi Arabian journalist Jamal Khashoggi, before opening a formal investigation.

Argentinian courts hear cases regarding crimes against humanity that were committed in other countries.

However, given the amount of time it will take for Lijo to make a decision once the requested information has been filed by the Foreign Ministry, it is not likely that the crown prince will stand trial before he leaves Argentina.
