Or. State. Bar. R. Regul. and Polic. 3.1
In representing a client or the lawyer's own interests, a lawyer shall not knowingly bring or defend a proceeding, assert a position therein, delay a trial or take other action on behalf of a client, unless there is a basis in law and fact for doing so that is not frivolous, which includes a good faith argument for an extension, modification or reversal of existing law, except that a lawyer for the defendant in a criminal proceeding, or the respondent in a proceeding that could result in incarceration may, nevertheless so defend the proceeding as to require that every element of the case be established.

"Knowingly"
Comparison to Oregon Code
This rule retains the essence of DR 2-109(A)(2) and DR 7-102(A)(2), although neither Oregon rule expressly confirms the right of a criminal defense lawyer to defend in a manner that requires establishment of every element of the case.
