(2B)If an original sanction to leave is in fact given after the event, i. e. after the close of the leave then sanctioned, the certificate regarding likelihood of return, which must logically be in the past tense, would be no less acceptable to audit on that account. What is wanted by audit is a written assurance by the competent authority that not later than the time he formally sanctioned the original leave, he then intended to re-post the grantee to a qualifying post. The fact that the grantee was so posted on return from leave is logically corroborative but not conclusive evidence of this intention, because the sanctioning authority may have intended otherwise when he first became aware of the fact of the absence, but changed his mind before the leave itself ended. Hence the contention that the fact of return to a qualifying post dispenses with the need for a declaration of intention is not correct nor would audit be entitled to demur if a sanction not in itself unreasonably delayed does logically contain a certificate worded in the past tense.
