Concept, nature, and classification of Law

- Origin: a mix of rationality, political interests, socioeconomic factors, and social values.
- Normative harmony: depends on the convergence of political interests and the stability of power.

- Prevalence: the special norm prevails over the general norm in specific cases.
- Repeal: the subsequent norm annuls the previous one.
- Objective law: mandatory norms created by the State (focus on validity).

Concepts of Objective and Subjective Law and Historical Evolution

- Publicity: A prerequisite for validity and the beginning of legal life.
- Validity: As a general rule, it is for an indefinite period from its publication.
- Rational drafting: Must include analysis of causes, effects, and formal requirements.
- Instrumentation: Requires secondary regulations and bodies for its application.
- Principle of legality: Prevents subordinate bodies from modifying or expanding the rule.

- Inviolability: the resistance of the norm against violation through sanction
- System: organically correlated norms with rank and precedence
- Legal order: a set of positive norms coordinated hierarchically
- Pyramid of norms: the classic representation of the legal system (Kelsen)

Sources of Law: Classification and Concepts
- Historical sources: ancient documents containing laws (e.g., Code of Hammurabi)
- Real/material sources: social, political, or economic factors that motivate the norm
- Formal sources: acts of the State or society to create laws (law, custom, doctrine, jurisprudence, general principles, treaties)
- Customary Law: unwritten law based on the repetition of acts with the force of law
- Custom: can fill legal gaps or repeal inconvenient laws
- Peru: Art. 149 of the Constitution recognizes customary justice in peasant and native communities
- Peru: Art. 66 of the Organic Law of the Judiciary recognizes justice of the peace
- Peru: Law No. 27908 recognizes the justice of the rondas campesinas (peasant patrols)
- Constitution: the fundamental norm of a sovereign State
- Law: a precept issued by a competent authority for the common good
- Jurisprudence: repeated interpretations by courts
- Legal act: an act of private autonomy with prescriptive content
- General principles of law: general normative foundations of the legal system
- Doctrine: opinions of jurists in essays, theses, or manuals

Legal Hermeneutics and Interpretation
- Hermeneutics: discipline for deciphering the sense and scope of legal expressions.
- Interpretation: determination of the meaning of the norm in a concrete and practical case.
- Authentic interpretation: performed by the same author of the norm.
- Non-authentic interpretation: performed by a third party other than the author.
- Declarative interpretation: coincides with the literal wording.
- Extensive interpretation: applies to more cases than the literal meaning.
- Restrictive interpretation: applies to fewer cases than the literal meaning.
- Subjectivist trend: the meaning is the intent of the legislator.
- Objectivist trend: the meaning is the intrinsic purpose of the law (predominant).
- Exegetical school: rationalism, infallibility of the legislator, omnipotence of the law, and adherence to the literal meaning.
- Free Law school: the judge is not subject to the literal meaning and seeks law independent of the State.
- Historical school: prioritizes the historical element to capture the "spirit of the people."
- School of free scientific investigation: seeks the social purpose and the idea of justice in the face of legal gaps.
Schools of interpretation, elements of the law, and legal integration
- Teleological School (Ihering): The purpose of the law is its essence and must have a social purpose.
- Formalist School (Kelsen): Pyramidal structure where the superior norm is a framework of possibilities.
- Rule-based system: Clear rules of interpretation.
- Non-rule-based system: Freedom of judicial action to interpret.
- Grammatical element: Meaning of the Diccionario de la lengua española (unless there is an express or technical definition).
- Logical element: Analysis of the ratio legis and internal harmony of the law.
- Historical element: Analysis of messages, motions, and minutes of legislative debates.
- Systematic element: Harmony between the precept and the entirety of the legal system.
- Interpretation of custom: Logical and systematic elements predominate.
- Interpretation of contracts: Rules of good faith, analogy, and favor debitoris (favor of the debtor) in ambiguous points.
- Legal integration: Construction of a norm in the absence of a solution for a generic case.
- Normative gaps (de lege lata): Lack of a solution in current law.
- Axiological gaps (de lege ferenda): An existing solution that is perceived as unjust or insufficient.
- Gaps in the law: Affect the entire system (rejected by Kelsen).
- Gaps in legislation: Affect only enacted law and are integrable by the judge.

Normative gaps, integration mechanisms, and branches of law
- Regulatory gaps: caused by system failures or problems of subsumption.
