The Supreme Court held that National Seeds Corporation Ltd did not enter into a valid contract with National Agro Seed Corporation India because the latter's response to NSC's tender constituted a counter-offer, not an acceptance. Under the Indian Contract Act, a valid acceptance must mirror the offer without modification. Since the respondent added new terms, the original offer lapsed, and no enforceable agreement arose. The Court applied the mirror image rule to dismiss the claim of a binding seed supply contract.

This judgment directly applies Section 7 of the Indian Contract Act, 1872, which requires that acceptance must be absolute and unqualified. The underlying doctrine is the mirror image rule: any acceptance that varies, qualifies, or adds conditions to the original offer is legally treated as a counter-offer, which automatically extinguishes the original offer. The original offeror is then free to accept or reject this counter-offer, but no contract exists until there is an unconditional acceptance on identical terms.

The distinction between a counter-offer and a mere inquiry is critical. A counter-offer substitutes new terms; an inquiry asks for clarification without altering the original offer. Only a counter-offer destroys the original offer.

The case also engages the concept of invitatio ad offerendum (invitation to treat): a tender notice issued by NSC is an invitation to treat, not an offer. The seed corporation's bid in response is the actual offer. NSC's acceptance letter, if qualified, then becomes the counter-offer. The Court's application clarifies which party was the offeror at each stage — a distinction the CLAT PG examiner routinely tests by reversing party positions in hypotheticals.

For NABARD and UPSC, the institutional angle matters: NSC is a Central Government undertaking under the Ministry of Agriculture, established in 1963, making any contract dispute it enters also a public procurement law question.
