You misunderstand what an argument from authority is if this is your justification for it. It's not "authority" meaning they can tell you what to do but instead meaning they are an expert on the subject matter. It is valid when a consensus of experts all say the same thing but if there is not an expert consensus then it starts to become more questionable. In this context, if many independent legal experts and scholars are looking at the decisions being made by the three branches of government and saying there could be bad ramifications, the argument from authority falls flat; there is another authority saying the first authority is wrong.
