I believe that in the interests of political stability in the region, there will be no criminal investigation.
On the contrary, parallel to the safety board investigation, a criminal investigation was launched by the dutch prosecutors office.
For any accident on dutch soil that would be the standard proceeding.
Considering the circumstances and the majority of the casualties being Dutch I understand international law gives the Netherlands the possibility here as well.
I doubt if it will have any practical value or anyone will ever be brought before
court but last week the prosecutors office announced the investigation is the biggest ever in its kind in the Netherlands.
Currently there are 10 prosecutors and 200 investigators in all kinds of fields on the case.
Unfortunately only in dutch:
strafrechtelijk onderzoek mh17 ramp grootste ooit
prosecutors office
BTW under dutch law I believe a CVR can not be used for a criminal investigation
