Guillen,

When I first saw this post, I didn’t think it was criminal law. (More context would have helped. And the term “respondent” threw me off.) Nonetheless, I can offer you a couple of resources regarding what I believe to be the correct translation for falta pasiva.

“Active offense” vs. “passive offense”
Only the act of payment, as opposed to the receipt/acceptance of payment, is prohibited.
Two offenses: (1)active offense: bribing another and (2) passive offense of being bribed.

As this court has noted, the aiding and abetting statute, 18 U.S.C. Sec. 2, "has broad implications and is one of the most important in the United States Criminal Code." United States v. Raper, 676 F.2d 841, 848 (D.C.Cir.1982).3 The statute codifies the deeply rooted common-law rule that those who intentionally assist a guilty principal may themselves be held liable as principals. Although possession is generally a passive offense, "nothing about drug-possession offenses is so distinctive as to remove them from the ambit of aiding-and-abetting doctrine." United States v. Staten, 581 F.2d 878, 886 (D.C.Cir.1978) (footnote omitted).
