Explanation:

Section 34 - ‘A’ seeks a declaration  that under a contract which has to be performed in future, he has a particular right.
If a contract is to be performed at a future date, it will not be a case of present entitlement, as the entitlement will arise only on the date of the performance of the contract. There is a possibility that the contract may get frustrated by the time of the performance of the contract, and thus, no question of any entitlement will arise. Moreover, even if a contract does not get frustrated, it may be breached and in that case also the aggrieved party concerned will  not get any entitlement under the contract, rather at the most it can claim damages. For a future right, declaration cannot made in the present.
