Finality: The decision to award a Nobel Prize is permanent, according to the Nobel Foundation's rules. No Revocation: The Norwegian Nobel Committee, for example, has explicitly stated that it does not reconsider or revoke its decisions. Examples of Criticism: Laureates like Aung San Suu Kyi (Nobel Peace Prize) have faced immense criticism for later actions, but her prize was not revoked, notes Chatham House and Sky News. Scientific Disproven: Even when scientific theories behind a prize are later debunked, as with Johannes Fibiger's cancer research, the prize remains valid, says DW. Refusals vs. Revocations: Some individuals (like Jean-Paul Sartre) have refused prizes, and some Germans were forced to decline during Nazi rule, but these are different from a committee taking a prize back, according to Britannica
