No proper delivery of summons

First of all - Speed Post is not a valid mode of service - It has to be via Regd. Post. 

Secondly - In case of service to a company - it has to be srved on secretary, local manager or other principal officer of the company not a guard. (S.63 CrPC)

Thanks for your response. Appreciate it.

In this case, For both the accuse (director) and the company, the summons were given on the same address and received and acknowledged by the guard. In such circumstances also, your above two points will remain valid, right?

Dear Querist

According to section 63 of Cr.PC

63. Service of summons on corporate bodies and societies.

Service of a summons on a corporation may be effected by serving it on the secretary, local manager or other principal officer of the corporation, or by letter sent by registered post, addressed to the chief officer of the corporation in India, in which case the service shall be deemed, to have been effected when the letter would arrive in ordinary course of post.

Explanation:- In this section "corporation" means an incorporated company or other body corporate and includes a society registered under the Societies Registration Act.1860 (21 of 1860).
