i think karar u r a little apprehensive about the subject.
If one study it (and i mean study) with true understanding NOT memorizing, one can attempt all case studies regarding it.
u have to give referances but it is not necessary that u give exact clause referance, only a referance to the heading of law is enough .
so i think it is an easy subject. I personally hope that some case studies should be present in the paper coz one more positive thing about them is that in case studies you barely got zero . if U explain your point of view clearly u got some marks. remember there r a lot of answers to a simple case, they just check ur objectivity.
