This paper contains the lectures delivered to the Ph.D Class in Corporate law at the University level. The object was to fresh the whole concept of company law made clear and to encourage the students to conduct further research themselves by going through the books, the journals, the articles, the thesis already written. They may also take help from the Internet and when they come in the class room they may themselves be able to discuss the topic or subject at issue. Company Law may be defined as a branch of law governing the companies. It is a law relating to companies formed under an Act or Ordinance, relating to regulation of the working and conduct of companies. Company law is a body of statutes and case law.Company law means the rule of conduct in respect of founding, promoting, making, getting registered, subscribing, holding, inviting investment, investing, crediting, meeting, resolving, running the affairs of a company and in case it is not possible to go on further to end it by an order of liquidation by a court or outside court. From beginning till end the objective is to do business in a useful manner as an association of those who are contributors in joint stock. The relationship is therefore fiduciary and commercial. A law made by a competent legislature or law-maker by whatever name it is called (i.e. an Act or an Ordinance) is a statute. There may be a single statute covering more than one subject or there may be more than one statute on the subject for any reason or wisdom. Those may have many names but the soul of them is the same. This differentiates between a law and the law. The plural of both is laws.Thus the Companies Ordinance, 1984 is a law. But there are other statutes which deal with the corporate affairs. Each one of them is a law. The soul or common wisdom lying in them is the law corporate.
