IANAL.
Whether that is true or not I can't say, but since they were hired by Chad and Lori and not appointed by the Court then isn't that fact irrelevant? From the link:
"(a) Applicability. The provisions for the appointment of counsel in this rule apply only in cases where the defendant is needy, as defined in Idaho Code § 19-851 et seq., counsel is not privately retained by or for the defendant, and the death penalty may be or has been imposed on the defendant."
1. The defendants are not needy as they have a substantial amount of money at this time; almost certainly and without question ill-gotten monies, but monies nonetheless.
2. Counsel has been privately retained by the defendants. They may or may not be qualified to handle the cases before them, but it is the right of the defendants to hire whoever they want, or even represent themselves if they so choose.
Since these two conditions exist, and since the above applicability rules apply only for Court appointed counsel (otherwise known as public defenders), then it seems to me to be a non-issue. But I could be mistaken. Again, IANAL.
