Origins and first constitutions of Mexico (Orígenes y primeras constituciones de México): Within this chapter the first findings in the history of Baja California are described, including cultural, religious and social aspects. The historical journey starts with the Spanish expeditions, going through the normative background that was current since novo Hispanic times and until after the independency, just in the middle of the 19^th century.

Border agreements of 1848 to 1853 (Tratados de límites de 1848 y 1853): In this section the impact that the North American invasion had in Mexican territory is presented, especially in Baja California, where after the split of the Alta California the following years would become complicated. Also, the economic use in the region by North Americans in terms of the state resources is mentioned.

Constitution of 1857 (Constitución de 1857): Here is presented, that the fundamental law from 1857, in despite of having strengthened its federal system, Baja California was not rejoined as a federative organization once the precept 43 assigned it again as a territory of the Mexican federation. In the book, the consequences of this process are shown among others. By not acquiring state sovereignty they could not create a constitution and as a consequence they also were not able to build their own local government bodies.

Constitution of 1917 and origin of the Constitution of Baja California (Constitución de 1917 y origen de la Constitución de Baja California): It is joined in this thematic axis the analysis of the evolution of the article 43 of this new federal constitution. The integral parts of this federation are delimited, and starting from the transcendent federal constitutional reform published on the Official Gazette of the Federation (Diario Oficial de la Federación) on January 16^th 1952, Baja California acquires the character of federative organization. It is constantly reviewed the general analysis of the institutions that are part of and created the Constitution of Baja California.

Territory of the State of Baja California (Territorio del Estado de Baja California): Here is presented the evolution of the territory bases of this federative organization. It is explained the objectives and contents of the three first constitutional precepts of the local fundamental law by studying the concept of state, and the analysis of the municipal legislation of this subject area.

State sovereignty, institutions and electoral process (Soberanía del estado, instituciones y proceso electoral): The complex concept of sovereignty is addressed in this chapter. As Hans Kelsen said: ‘‘in the idea of a form of state or society, the collective will or more precisely, the social order, will result generated by its own subjects, in other words, the people’’ (^{Kelsen, 2005, p. 30}). Such peculiarities are expanded with the author ideas, as well as the definition by great jurists that sustain argumentation. It is also addressed the topic of the electoral process in Baja California. It begins with the acknowledgement granted to Mexico by the development of the election law and the design of its own electoral institutions; both administrative and legal.

Official symbols (Símbolos oficiales): In this section it is explained the particular situation of the Bajacalifornian fundamental law that provides the regularization of official symbols of this organization since the Constitution of the Mexican United States (Constitución Política de los Estados Unidos Mexicanos) did not provided it in its content. Even though this omission has not significance, in the fundamental law of Baja California this topic is constitutionalized, creating an interesting legal precedent.

Human rights and their protection (Derechos humanos y su protección): Fundamental rights in Baja California are found constitutionalized under reminiscing criteria of the Federal Constitution. Therefore, we can confirm that in this chapter, every human right recognized by our constitution and the international agreements that the Mexican State is part of, is constitutionalized, as well as the guarantees for their own protection. Their own exercise could not be restricted or suspended, only in the cases and conditions that the same Constitution dictates.

State inhabitants, duty and rights (Habitantes del estado, derechos y obligaciones): The chapter number V of the title I of the Constitution of Baja California is studied in this part of the book. The demographic element is carefully analyzed by the author. She made observations such as the omission in the development of precepts that regulates the acknowledgment of the inhabitant character of the state, or also the absence of determined residence demands for occupy public positions in the state.

Public power and form of government (Poder público y forma de gobierno): This chapter provides us the presentation of the investigation about the organic part of the bajacalifornian constitution. It is explained the characteristics of the form of government; republican, representative, popular, democratic and lay. It is given as well, an explanation about the three government bodies from the three structural functions of the state: legislative, executive and judicial.

Municipal regime, (Régimen municipal): In this chapter the municipality is studied as an institution of public law of political-administrative character, which within a state is a territorial district from the public administration and represents the first authority to the citizen. It is highlighted that the municipality:

Public finance and regimen of responsibilities in public sectors (Hacienda pública y régimen de responsabilidades de los servidores públicos): This two important constitutional themes are objects of study where the author makes mentions of doctrinal concepts which make her able to argument that ‘‘the fiscal coordination’’ and generally the fiscal federalism, were motives of multiple questionings that should be improved in our country in order to endow major tax powers and improve the distribution mechanisms of the fiscal resources to the federative entities. This is suggested in order for the local governments to access major resources and therefore, improve the obligations with their communities and impulse the regional development. Regarding the regimen of the responsibilities of public servers, some thoughts are presented about the necessity of reinforcing the professional ethic, the transparency and anti-corruption mechanisms as key elements of the public administration and of the justice system.
