Ruth White wrote to the High Commissioner of Palestine stating that she had sent a photograph of 'Abdu'l-Bahá's Will and Testament to Dr Ainsworth Mitchell in England who had declared it a forgery. The High Commissioner requested she send that same evidence to him and he forwarded it to the Governor of Haifa who requested to meet with Shoghi Effendi and allow an expert to examine the original. The expert declared the Will authentic. [SETPET1p157]
