Pedigree – Norms and the principles governing the proof of a pedigree by oral evidence – In order to appreciate the evidence of such witnesses, the following principles should be kept in mind :
“(1) The relationship or the connection however close it may be, which the witness bears to the persons whose pedigree is sought to be deposed by him.
(2) The nature and character of the special means of knowledge through which the witness has come to know about the pedigree.
(3) The interested nature of the witness concerned.
(4) The precaution which must be taken to rule out any false statement made by the witness post litem motam or one which is derived not by means of special knowledge but purely from his imagination, and
(5) The evidence of the witness must be substantially corroborated as far as time and memory admit.”
