Document not despatched by a govt office can be produced in evidence

It does not require a despatch number for a produced document. However, what is the opinion of your lawyer in this matter? 

If the document bears signature of authority and seal then it is admissible in evidence. 

I endorse the opinion and advise learned senior expert Mr. Bhartesh Goyal.

The point in issue is the signature of author the letter / document and not the despatch number.

What is the opinion / advise of the lawyer engaged by you, if any ? 

Thanks for your reply,

As per regulations of a document is not Despatched it means a formal delivery to the recipient has not materialised , and the paper officially is still with the Deaprtment. Such a non-desoatched document implies that the it is still under process and no final shape has yet been given . 

All worthy advisers may please advise on the above .

It is (service of the subject document) to be proved by the party exhibiting, if doubted/ objected or questioned in cross-examination.  

Otherwise, it stands proved.
