Mercantile Law (ASP Kamran Adil)
Assalam-o-Alikum!

" In my view, for a general study it is enough to go through a general book first like that of Cheema on Mercantile law, for the very first thing to do is to cover all the topics. This should be followed by a detailed study of specific questions and solving of the past papers should be the last thing. Anyhow, to enhance academic quality, you are further advised to go through Schukla's Mercantile law.

Now a word about the contents of ML. My perusal of the past papers has revealed that the subject caters to six laws namely:

1. Law of Contract;
2. Law of Sale of Goods;
3. Company Law;
4. Law of Partnership;
5. Law of insurance;
6. Law of Negotiable Instruments.

Moreover, you can and you should, for the sake of better approach also see the original statutes in which all these law are codified. Finally you should start with law of Contract, which is mother of all the laws stated above."
