A transfer to foreign service is not admissible unless :—
(a) the duties to be performed after the transfer are such as should, for public reasons, be rendered by a Government servant ; and
(b) the Government servant transferred holds, at the time of transfer, a post paid from general revenues ; or holds a lien on a permanent post, or would hold a lien on such a post had his lien not been suspended.
Note 1 :—The Government of India have held that the transfer of a temporary Government servant to foreign service is permissible.
Note 2 :—The loan of a Government servant to a private undertaking is to be regarded as a very exceptional measure requiring special justification on a rigorous application of the principle enunciated in clause (a) of this rule.
