6 Once the contractual period expired, petitioners cannot, as a matter of right, seek continuation or insist upon release of salaries or budget allocations from public funds. The principle is well settled that contractual or finanbial rights must arise from express terms and not by implication or inference. The impugned Memo, on its face, only restrains preparation of bills in respect of employees whose engagement is not covered lt by a valid subsistirig contract and appears to have been issued to ensure administrative and financial propriety. Pendency of the connected Writ Petitions challenging the tender proceedings does not, by itself, create any interim entitlement to claim payment under an expired contract. The appropria$ course fo. petitioners, .if aggrieved, would be to pursue their remedies in the pending Writ Petitions, wherein all aspects of the empanelment process are under consideration, This Court, therefore, finds no ground to interfere with the impugned administrative action, particularly when no statutory violation or mala fides have been established on record.
