Thanks,LinTX, but what does this mean?
Im really curious what this motion to disqualify means! Couldnt find much info on Dept M, but did see that jurisdictional issues typically relate to the timeliness of filing an appeal, which doesnt apply here, as an appeal was filed within 30 days.
Its been a very long while, so I reread the COAs written ruling, looking for any clues. Appellate Judge Cattani wrote the possibly problematic article about CMJA. He was not, however, on the panel of judges who decided against CMJA in the COAs special action ruling (judges were Portley, Orozco, and Randall ).
Knowing what might be legally relevant in the COA ruling is way way above my paygrade, but I took a shot at it anyway.

In their ruling the COA asserted that:
1. It was within their discretion whether or not to accept jurisdiction of the special action (media asking for a stay of Stephens ruling).
2. That they did not need to decide any constitutional issues in order to make their ruling, and ultimately did not, instead relying upon AZ Criminal Code.
3. Their decision was based on analysis of whether or not a clear and present danger existed that merited clearing the courtroom of media as well as spectators.
4. They interpreted JSSs decision to clear as one arising from her concern that an appellate court could later determine that CMJA didnt voluntarily wave her right to present mitigating evidence.
5. The COA explicitly stated that this concern did NOT meet the standard of a clear and present danger to CMJAs trial rights.
6. The COA further stated that even if CMJA refused to testify, mitigation could be presented using evidence from the guilt phase and first penalty phase trials. It was in this section of reasoning the COA stated that a defendant who testified in open court during the guilt phase couldnt decide not to testify in the PP.
7. One footnote might be of interest: Although Arias argued to the trial court that her refusal to testify might not be voluntary, nothing in the special action record reflects that she would waive her right to present any mitigation if the proceedings are not closed.
Obviously, CMJA did indeed refuse to take the stand again, and IIRC, AZL was pretty sure that one of the docs presented to JSS and sealed was the testimony CMJA would have given if the court had remained closed.
So
..an uneducated guess. IF the motion to disqualify the COA isnt some meaningless and arcane procedural thing, or about asking Cattani to recuse himself, or a bid to bypass the COA altogether and go directly to the AZ Supreme Court, maybe the appellate atty is arguing that CMJA did not voluntarily decline to present mitigation evidence, and that the COA as a whole shouldnt be allowed to review her appeal because of this previous ruling.
I still dont see how it makes any sense to bypass the COA on any grounds, unless CMJA has indeed decided to expedite her state-level appeals in the misguided hope that a federal circuit court would be more sympathetic to claims of constitutional violations.
Looking forward to any answers you've come up with, Lin TX. Your research ROCKS!
