I've read that she wanted him completely removed and ownership put in the hands of a trust management company, whereas they've said it should be joint.Why can't they just appoint someone else? I don't know the specifics but I know for a fact courts have the ability to appoint someone in their stead to help them out. They did one to Amanda Bynes I think.
Without knowing the full details, I wonder whether the sticking points is if it's met the threshold for him to be removed and only have one custodian.
Perhaps, it's better to have two than one? I'm not saying that's right, however I am trying to surmise why the judge has declined it on legal grounds.
A quick peruse suggests a new claim, based on the new evidence, will likely to be more successful e.g. it was looking at one aspect and not new evidence.
