In a purely hypothetical question...let's set the hypothetical in Arizona in the United States as a default jurisdiction for the question, although other U.S. jurisdictions would be useful and of course around the world would be interesting.
Let's posit an individual is crowdfunding an organized effort to compel the government to change something. As a part of that effort, "proof" of the legitimacy of their ongoing fight is the existence of legal claims they are filing in court.
The courts in this scenario have found that not only are these suits without merit, they often do not even pass the frivolous standard and are otherwise ridden with legal errors unbefitting of any serious attempt to actually win in court. Thus, they have had multiple cases dismissed, yet they find ways of continuing to file different objections to the government action to show the people that they are asking for money from that they are still fighting and can absolutely win this thing.
Does using the courts in this way violate any law other than the individual sanctions for improper suits? In particular, is there any way to go after the money being fundraised for an activity that seems on its face to be of fraudulent intent? (I.e. filing cases with 0 chances of winning just to be able to dupe people into thinking their money can be used to help win an unwinnable fight?)
If there was such a way, would it be the state or federal government pursuing the case, or could any private actors have standing? The only ones I could think of are those who donated on the belief of the false claims who later felt defrauded.
