It is not possible to revoke a Nobel Peace Prize. Neither Alfred Nobel’s will nor the Statutes of the Nobel Foundation mention any such possibility.
According to the Statutes of the Nobel Foundation, § 10, “No appeals may be made against the decision of a prize-awarding body with regard to the award of a prize”.
None of the prize awarding committees in Stockholm and Oslo has ever considered to revoke a prize once awarded.
As a matter of principle, the Norwegian Nobel Committee never comment upon what the Peace Prize Laureates may say and do after they have been awarded the prize. The Committee’s mandate is restricted to evaluate the work and efforts of the nominated candidates up to the moment it is decided who shall be awarded the Nobel Peace Prize for a given year.
However, criticism of Nobel Peace Prize laureates after they have been awarded is something the Committee tries to follow closely, sometimes with great concern.
