The state contract may contain a condition that contractors begin to fulfill obligations only after finishing limits of the budgetary obligations.
Department has noted: the conclusion of the state contract in the absence of limits of the budgetary obligations can lead to untimely payment on him and entail expenses of budgetary funds for payment of a penalty. At the same time the Law N 44-FZ doesn't forbid to sign the state contract under a suspensive condition.
In 2015 already I pointed the Ministry of Finance to an opportunity to include a suspensive condition in the state contract.
