Tax Equity: A Rational Reconstruction of Spanish Constitutional Jurisprudence

Abstract

In this work I will discuss about the concretion of the principle of tax equity. Its purpose is being an academic contribution in order to consolidate the legal doctrine of tax equity. Specifically, I will analyze different conceptions of inequality and its treatment in tax matters; also, I will explore cases of violations of this principle.
To achieve the purpose, I analyze Comparative Law; specifically, jurisprudence of the Spanish Constitutional Court. The conclusions are consequences of a rational reconstruction of those decisions by using the logic model of normative systems of Alchourrón y Bulygin.
