Rule 10 of the CCS(CCA) Rules applicable to Central Government employees provides for deemed suspension in case of detention in custody beyond 48 years-
10. Suspension
(1) The appointing authority or any authority to which it is subordinate or the
disciplinary authority or any other authority empowered in that behalf by the
President, by general or special order, may place a Government servant under
suspension-
(a) where a disciplinary proceeding against him is contemplated or is pending; or
(aa) where, in the opinion of the authority aforesaid, he has engaged himself in
activities prejudicial to the interest of the security of the State; or
(b) where a case against him in respect of any criminal offence is under investigation, inquiry or trial:
Provided that, except in case of an order of suspension made by the Comptroller and Auditor - General in regard to a member of the Indian Audit and Accounts Service and in regard to an Assistant Accountant General or equivalent (other than a regular member of the Indian Audit and Accounts Service), where the order of suspension is made by an authority lower than the appointing authority, such authority shall forthwith report to the appointing authority the circumstances in which the order was made.
(2) A Government servant shall be deemed to have been placed under
suspension by an order of appointing authority -
(a) with effect from the date of his detention, if he is detained in custody,
whether on a criminal charge or otherwise, for a period exceeding forty-eight
hours;
(b) with effect from the date of his conviction, if, in the event of a conviction for
an offence, he is sentenced to a term of imprisonment exceeding forty-eight hours and is not forthwith dismissed or removed or compulsorily retired consequent to such conviction.
EXPLANATION - The period of forty-eight hours referred to in clause (b) of this subrule shall be computed from the commencement of the imprisonment after the conviction and for this purpose, intermittent periods of imprisonment, if any, shall be taken into account.
The public sector companies have more or less adapted said provisions in their discipline rules.
An employee placed under deemed suspensions requires to be paid subsistence allowance, as admissible, irrespective of whether he is in custody or otherwise.
