Research Lines
Corporate Litigation
It covers several topics related to corporate litigation, especially with regard to the explicitness of the fundamentals of the corporate institutes in their relation with legal methodology and with the general part of private law, as well as the analysis of the practicability of those institutes in view of the procedural instruments that perform them. The topics of liability of company managers, quitus, typology and materialization of fiduciary duties, minority abuse, action of managers without powers, legitimation problems in corporate law, total and partial dissolution, assumptions and consequences of the disregard of the legal entity and partners’ liability for the company’s bankruptcy are highlighted.
Structural Principles of Corporations
Covers the study of the institutes that regulate business corporations as manifestations of structuring principles that allow them to be understood in a consistent and systematic way, and not as sets of isolated rules. Topics related to the principles of capital protection (patrimonial bond), division of powers in the joint stock company, implicit powers of the general meeting, and implications of the principle of equal treatment of shareholders, as well as clarifications regarding the notions of purpose and social interest, are emphasized.
Problems of business contract law
It covers the analysis and understanding of new clauses of corporate practice through the dogmatic instrument of private law, the analysis of typical situations of contractual conflicts as a method to solve complex litigation, specific problems in insurance contracts, leasing and commercial representation (agency, distribution, commission and brokerage), problems related to atypical guarantees, and the study of the interface between contract law and corporate law, especially with regard to the competence and responsibility of directors in the execution of contracts by the company.
