Des que va ser anomenat Relator Especial de drets humans a l'Iran l'any 2011, a Shaheed se li ha negat l'entrada a l'Iran i els seus informes anuals, en què detalla una consistent violació dels drets humans, han estat descrits com a "mentides" pel director de la judicatura iraniana, Sadegh Amoli Larijani, i com a "invàlids" pel portaveu del Ministeri d'Afers Exteriors, Marzieh Afkham.
Since being appointed as the UN’s human rights point-man for Iran in 2011, Shaheed has been refused entry into Iran, and his annual reports, detailing widespread rights abuses, have been described by Sadegh Amoli Larijani, Head of the Iranian Judiciary, as “lies” and by Foreign Ministry Spokesperson Marzieh Afkham of “lacking validity.”
