Rule 7 of the Central Civil Services (Leave) Rules, 1972, is headed “Right to leave.” Its first sub-rule reads: “Leave cannot be claimed as of right.” The second adds: “When the exigencies of public service so require, leave of any kind may be refused or revoked…”
In 2014 the Supreme Court quoted the rule in Kakali Ghosh v. Chief Secretary, Andaman and Nicobar Administration.
A rule headed “Right to leave” begins by saying that leave cannot be claimed as of right.
