18 Baylor L. Rev. 251 (1966)
PROSECUTION OF THOSE ACCUSED OF A CRIME - NEGOTIATIONS WITH THE OPPOSITE PARTY
Since the defendant in a criminal action is a party, a district attorney may not attempt to elicit a statement or plea of guilty from the defendant nor submit him to a lie detector test or otherwise deal with the defendant without consent of his attorney when one has been engaged. The duty of a district attorney is not to convict, but to see that justice is done.
Canons 5, 9.
We can start with two propositions which are axiomatic.
It is our opinion that a person charged with a criminal offense is a party as that term is used in the first two sentences of Canon 9. Opinions are plentiful, both by the American Bar Association Committee and by this committee, to the effect that comparable conduct in a civil case would be unethical.
We have carefully checked every opinion by this committee and by the committee of the American Bar Association and find only one opinion on this question. In Opinion No. 87, this committee held that it violates Canons 19 and 22 for a prosecuting attorney to have a defendant in a criminal case examined by doctors during the course of the trial without the knowledge or consent of counsel for defendant. We think that opinion reached the correct result but assigned the wrong reason. It is difficult to see how Canons 19 or 22 have any application.
It is our opinion that all three questions submitted are the same. The conduct described in each violates Canons 5 and 9. (9-0) (See Opinion 144)
