Legal Question in Criminal Law in Arizona

I would need more information to give you a relatively firm answer (for example: what court, what charge(s), her prior record, whether the warrant is subject to extradition etc.). If your wife has a lawyer in the California case, and depending on the AZ charge, he/she can call or write the AZ Court explaining your wife's circumstances and asking the Court to quash the warrant on the condition that when she is released in the California matter she will appear at the Arizona Court and clear up that matter. I've had some success in this approach, but again it is difficult to answer such a question without more information. You may need to consult directly with a lawyer.
