Gujarat High Court Criminal Manual (subordinate court practice), 1977
It is desirable in judicial proceedings to prevent, as much as possible doubt as to the identity of the persons referred to therein. It frequently happens that the same individual is known by more names than one. Thus sometimes only the surname, sometimes only the name of the caste, or occupation or the village of the individual is mentioned or he is spoken of by a nickname. Such variations in description require explanation to render them intelligible to an appellate Court. A Court of first instance should, therefore, take care not only to ascertain but to make clear by evidence duly recorded the identity of any individual who is so referred to under varying appellations and if such an individual is an accused person, his name and serial number according to the charge sheet should be cited in any passage in which he is otherwise designated.
