Contrary to popular belief sometimes, judges are not intimidated by where someone works, even if they work for the federal government, as judges know which higher levels of federal government to go to and complain if they believe an employee is trying to intimidate them and a judge's complaint is enough to get him fired. So there has to be some other issue, such as the judge has so many cases they have not been able to get to your case.
Under FL law, if your daughter can prove the children have resided in FL at least 12 months, they are deemed FL residents. Under the law, if the original order was from CA (or from any state other than FL or MD, where you say he lives now), then the custody laws state that the CA court must either release jurisdiction or the FL judge must determine that not only are the children residents of FL, but that there is no longer sufficient contact with the original state by ANY of the parties, meaning he no longer lives in the original state and she and the children no longer resides in the original state, then the FL court can take jurisdiction under the uniform laws on child custody and support.
Based on the information above, the judge should find jurisdiction in FL with her and the children being FL residents and that if he no longer lives in the original state of the court order, that state no longer has jurisdiction. However, you need to check with the judge's court clerk to see where your case is in the judge's list of decisions and you will have to wait for the judge to issue their ruling I am afraid. If you file any motion demanding a decision or file a writ of mandamus to the appellate court to force a decision, it can cause the judge to not rule as favorably for you as they may have been getting ready to do (what I mean by that is if there is any gray area that could go either way they may go in favor of the other party on those issues).
