You cannot enjoy CL if it is not granted by your HM and one cannot claim CL as his/her right. Generally CL is granted proportionately, i.e., you cannot enjoy all the CL in the beginning months of an academic session. An HM may not allow a staff to enjoy more than 7 CL within first 6 months. There is also a logic behind this clarification. Suppose a staff resigns and joins another school in the middle of a session (through Mutual or General Transfer or SSC) and he has enjoyed all the 14 CL in his previous school. Now one does not carry the the record of CL to his new school, it is ML account which is carried to new school in his service book. That does not mean that he can enjoy all the 14 CL again in his new school in that same session. He will be allowed to enjoy CL proportionately in both the new and previous school. In fact, all the staff are allowed to enjoy CL in the same manner, i.e., proportionately.
