Articles' Leave

I have a question regarding the leave calculation of total article ship period 3 and 1/2 year. (Reg.: PCC)

In Training Guide it is clearly mentioned that an article can take a maximum of 2 months study leave for the examinations conducted by ICAI, except at principal’s discretion on allowing more than 2 months leave out of his total leave due for 6 months. His actual period of service should be 3 years. But it is not mentioned in any where that, if the leave due to an article is more than 2 months for say 3 months before his final examination, then is there any need of principal’s discretion to take the leave of more than 2 months?

The following example can clear the moto of my question:

Date of Joining the Article ship: 16^th April, 2007 & Date of Completion: 16^th October, 2010 (Total Period: 3 & 1/2 Years)

	No. of Days
Total Period of Service :
From 16th April,2007
To 16th October,2010
A) Total Days Served	1279
Less: Interim Leave Taken:
PCE Examination November'08	60
Others	15
Expected Leave to be taken for Final Exam	105
B) Total Leave Taken upto 16^th October,10	180
C) Actual Period of Service 16^th October,10 {A)-B)}	1099
Entitlement of Leave	183
(1/6th of the Actual period Served)
D) Total Entitlement of Leave upto 16^th October,10	183
Excess Leave/(Leave Due) {B)-C)}	-3

In the above example the Leave taken for final exam is more than 2 months. And he has taken interim leave for 2 and ½ months. So the remaining 3 & ½ months i.e. 6months minus 2 & ½ months will be the leave due before his final exam.

My question is that, can he avail the leave for more than 2 months without principal’s discretion although he has served actual period for 3 years?
