“Dear friend, let me first beg your pardon because of being too late to reply.
1. I have no idea if there is any concept of advance medical leave.
2. A permanent teacher is allowed to enjoy 15 medical leave for each completed year. so your friend may be allowed at least 30 medical leave.
3. A permanent teacher is allowed 30 half pay leave each year or commuted leave half of the HPL. So, s/he is entitled for 15 x 2 = 30 commuted leave for two years.
So it is cleared s/he may be allowed 60 leave (because two kind of leave of this kind is allowed to be combined)
So 69-60= 9 leaves are to be taken as leave with out pay.
How ever, if the authority consider the joining date as his/her service life, they may calculate the service life as 2 years and 3 months (though it is not COMPLETED YEAR AS SAID IN THE 1999 LEAVE RULE, so it is completely their own consideration) and allow leave proportionately, your friend may be allowed 15 x 2.25= 34 (in round figure) medical + 15 x 2.25= 34 (in round figure) =68 days of leave. And if the authority is little more generous they may allow full 69 days of leave(considering one day more) under the provision of special leave for prolonged illness. However the authority may also consider as 3 years of service (including the current year, not sure whether is there any provision of that) and allow all the leave in combination of medical and commuted leave.
Dear friend I have tried to answer according to my best judgement but I must request you that you should post any query in the forum for public discussion. Obviously you may send PM to member of your choice to reply to that query. Because PM is no means to bypass the discussion in the forum. I am really sorry if you have already posted in the forum and I missed it. Please correct me if so. However I am posting your query and my answer in the forum for discussion (with out your name as i don’t know whether it may affect your friend)”
