Extraordinary leave during probation in punjab

Sir/mam

I have joined Govt. Of Punjab in Dept. of Health & Family Welfare as Medical Officer . Its's Group A post also known as PCMS-I .

Regarding above said topic I have few queries :

Ques no. 1 ::: I want to go on "leave without pay" . Is "extraordinary leave " same as "leave without pay" ??

YES

Ques no. 2 ::: If same How do I apply for it ?? How much time in advance do I have to give the application ??
 

CONTROLLING OFFICER MAY GRANT IT EVEN IF APPLIED ONE HOUR IN ADVANCE OR MAY NOT GRANT EVEN IF APPLIED SIX MONTHS  IN ADVANCE.

Ques no. 3 ::: Max duration of this leave I can avail at a stretch or in pieces ??

JUST LIKE ANY OTHER LEAVE

Ques no. 4 ::: Who will be the sanctioning authority in my case ??

JUST LIKE ANY OTHER LEAVE
