Relación causal y exclusión de prueba

This work study the causal relation between the breach of an evidence collection rule and the evidence exclusion, or the prohibition of evidence's assessment within the criminal procedure, respectively. Regarding this point, the research intends to define criteria to prove or to discard said causal relation regarding evidence matters and the consequences arising in the event said relation is proved or not. The proposed analysis uses a comparative law perspective, based in the U.S, German and the Chilean judicial systems, including in each case relevant doctrine and jurisprudence.
