The witness who will help in proving your case beyond reasonable dobut is required. there is no fixed number is decided by the law. it may be one or more. you need not to search any case law for this. The Evidence Act will helpful to resolve you doubt.

The right words are already chosen by you..relevance and justification.

The contentions of OP, lawyer of OP are to be handled by your own lawyer.
