If I understand right, you do not have fixed weekly off and instaed take compensatory leave, As per law such compensatory off must be taken within nine days.Such compensatory off wil be consideered as your weekly off. Hence Casual leave can be combined with Compensatory off. In the same spirit, when you work on a national and festival Holiday and take a compensatory Off on a different day, such a Compensatory Off should also be considered as National Holiday and as per you Company policy, CL leave can be suffixed or prefixed to such Compensatory off as well
Clubbing Casual leave and compensatory leave is ok a capital letters and should be within rules.
However the way you have posted the query with capital letters anywhere and everywhere makes for poor sentence construction.
You are posting on a public forum,some care for proper sentences needs to be taken.
