Normal Equanimity Rule; Passion, Obfuscation

To be entitled to this mitigating circumstance, the following elements must be present: (1) There should be an act both unlawful and sufficient to produce such condition of mind; (2) the act that produced the obfuscation was not far removed from the commission of the crime by a considerable length of time, during which the perpetrator might recover his normal equanimity.
