Diálogo entre municipios y estados: principio de fuente constitucional
States and municipalities are two actors of our constitutional federalism, both with a peculiar relationship of attachment in important decision whereas both holding, at the same time, spaces of autonomy protected by the Constitution; thus, state legislatures have power over the taxing power and the integration of municipalities, which, if misused, would certainly derail the design of power fragmentation foreseen by our founding fathers; this paper explores a body of precedents built by the Supreme Court justifying a constitutional judicial review over these political decisions, which consists of different standards of judicial scrutiny by which to evaluate not the content of what is decided, but the processes of decision making and its assumptions; thus, the model is not to have a judicial power ruling on the merits of the law resulting from their normative relationship, but preoccupied by the openness of political channels, which give rise to those decisions.
LA CIENCIA DEL DERECHO PROCESAL CONSTITUCIONAL
La finalidad del presente estudio consiste en ubicar el periodo fundacional del derecho procesal constitucional como nueva disciplina cientifica. El autor parte de la manera en que surgen las diversas disciplinas del derecho procesal y del derecho constitucional, ambas como fruto del derecho publico aleman del siglo XIX. De ahi analiza las cuatro etapas de conformacion del derecho procesal constitucional que ubica entre los anos de 1928 y 1956, a la luz del procesalismo cientifico de la epoca, y de las ensenanzas de Kelsen, Couture, Alcala-Zamora, Calamandrei, Cappelletti y Fix-Zamudio
The Area of Freedom, Security and Justice ten years on: Successes and future challenges under the Stockholm Programme. CEPS Paperbacks. June 2010
This book celebrates the tenth anniversary of the Area of Freedom, Security and Justice (AFSJ) by bringing together the views of key practitioners and policy-makers who have played an outstanding role in thinking about and shaping EU policies on freedom, security and justice. 
 
Ten years ago, the member states transferred competences to the EU for law and policy-making in the fields of immigration, asylum and border controls, and began the transfer process for criminal justice and policing. This decade of European cooperation on AFSJ policies has experienced very dynamic convergence, the enactment of a large body of European law and the setting-up of numerous EU agencies working in these domains. Such dynamism in policy-making has not been without challenges and vulnerabilities, however. As this collective volume shows, the main dilemmas that lie ahead relate to an effective (while more plural) institutional framework under the Treaty of Lisbon, stronger judicial scrutiny through a greater role for national courts and the Court of Justice in Luxembourg, better mechanisms for evaluating and monitoring the implementation of EU AFSJ law and a more solid fundamental rights strategy. The contributions in this volume address the progress achieved so far in these policy areas, identify the challenges for future European cooperation in the AFSJ and put forward possible paths for making more progress in the next generation of the EU’s AFSJ.
