A government department cannot unilaterally impose new financial conditions or obligations via retrospective clarifications that modify the express terms of a previously signed and binding agreement between the state and a contractor.

Headnote:(A) Contract Law - Mobilization Advance - Agreement conditions vs. departmental clarification - Petitioner availed mobilization advance for machinery as per original agreement clauses - Department attempted to charge 15% interest based on a retrospective departmental clarification prohibiting advances for pre-owned machinery - Court held that departmental clarifications cannot override or unilaterally modify binding contractual terms - Impugned demand for differential interest held unsustainable. (Paras 6, 12, 13, 14, 15)

Facts of the case:
The petitioner, a Joint Venture, was awarded a contract and received a mobilization advance for machinery as per the agreement. Years later, based on a Vigilance and Enforcement report and a subsequent departmental clarification, respondents demanded differential interest at 15% and withheld bank guarantees, claiming the machinery was pre-owned and ineligible for the advance originally granted.

Findings of Court:
The court found that the agreement did not prohibit pre-owned machinery or distinguish between new and old ownership for the purpose of mobilization advance. The retrospective application of a departmental clarification to impose new financial burdens was deemed illegal and arbitrary.

Issues: Whether departmental instructions issued post-contract can unilaterally alter the terms of a signed agreement and whether the petitioner is liable to pay enhanced interest for using pre-owned machinery not expressly prohibited by the primary contract.

Ratio Decidendi: Once a contract is signed, parties are strictly bound by its original terms. A unilateral clarification cannot impose new obligations, modify existing conditions, or add financial burdens not previously anticipated by the parties.

Result: Writ petition allowed; impugned demand notices set aside.
