Civil Service Personnel Rule 53

53. Regarding the initial pay:
(a) when an external person is initially appointed as a service personnel to a post in the organizational set-up, the initial pay to be allowed shall be the minimum of time scale pay;
(b) in a case of a service personnel is transferred to the post of greater responsibility with the identical time scale pay, an additional increment shall be allowed at the current time scale pay.
(c) in transferring to the immediate lower post on the request of a service personnel, the maximum of the time scale pay of that post shall be allowed as initial pay.
(d) when the authority for demotion transfers a service personnel to the immediate lower post in accord with the punishment, such service personnel may be allowed a suitable pay not exceeding the maximum pay of that lower rank post.
(e) there may be a case where a service personnel promoted to a higher post is demoted to the previous post while serving at the higher post. Again, if that service personnel is reinstated to the previous higher post or to the other post of the identical time scale pay, the initial pay of such service personnel shall not be lower than the last pay of such post previously. The period enjoying that previous pay shall also be taken into account in calculating the increment.
(f) in case of pay scale of a particular post or a category of such post changes, the current pay of previous time scale pay being enjoyed shall be specified as the initial pay of new time scale pay. The date of increment of old pay scale shall be continued to calculate in calculating the increment.
