Extensions in service defy logical principle of expectation: Vice President

''We have a doctrine of expectation. People devote decades to be in a particular groove. Extension indicates that some individual is indispensable. Indispensability is a myth. Talent abounds in this country. No one is indispensable. And therefore, it lies in the domain of public service commissions at the state and the central level that when they have a role in such kinds of situations, they must be firm,” he said delivering the inaugural address at the 25th National Conference of Chairpersons of All State Public Service Commission at Bengaluru.
