The SODDI defense ("Some Other Dude Did It" or "Some Other Dude Done It" [1] ) is an informal phrase referinig to a legal defense argument in which the defendant does not deny that a crime (e.g., murder or assault) occurred and is not asserting self-defense, but rather is asserting that they are not the one who did it. [2] It is also known as the alternate suspect defense. [3] The SODDI defense in a murder, rape or assault case is often accompanied by a mistaken identity defense and/or an alibi defense. Another common scenario where the SODDI defense is available is where the police find contraband in a car or residence containing multiple people. In this scenario, each person present could assert that one of the other people possessed the contraband. [4]
In Holmes v. South Carolina , 547 U.S. 319, 126 S. Ct. 1727, 1731, 164 L. Ed. 2d 503 (2006), the US Supreme Court held that a South Carolina statute that prohibited putting on a SODDI defense when the state's case was "strong" violated the Sixth Amendment right to put on a defense. [5]
