This special edition of “Dos Mil Tres Mil Law Review” has been thought out as a tribute to the post graduate specialization course in Administrative Law of the University of Ibagué. It includes the work of several authors, who have rendered their conjectures and proposals on topics such as the abuse of voting rights in simplified corporations, the right to the freedom of political speech on social networks, and the discussions that take place regarding the ascription of state liability due to damages caused by unconstitutional laws.
