The course aims to illustrate and deepen the law of business and companies in our legal system. Based on the study carried out, the student must therefore demonstrate adequate skills in relation to the discipline: (a) general business law (notions and categories of entrepreneurs, organizational models, operating rules and specific events, etc.); (b) of partnerships (organization, development and dissolution of the relationship, taking into account the different rules applicable to simple partnerships, general partnerships, and limited partnerships); (c) of corporations (formation, organization and operation, shares and quotas, financing, groups, composition and powers of corporate bodies, regulation of listed companies, balance sheet, amendments to the bylaws, extraordinary operations). The course, also through the proposed teaching activities, aims to promote, in the student, the ability to use categories of legal analysis and interpretation, the acquisition of an appropriate legal language, a correct method of presentation, also developing adequate critical and argumentative skills through the solution of practical questions and cases proposed in class. In this perspective, students will be presented with materials, available on the e-learning platform (e.g. draft corporate bylaws, shareholders' agreements, company resolutions, contracts, as well as well-known legal cases) to allow them to both frame typical cases and characteristic institutes of the subject, and observe their concrete application in practice. Since the commercial law course is preparatory to the advanced commercial law course, students are required to acquire a level of learning of the basic discipline that allows for an easy and productive attendance of subsequent courses.
