The arrest warrant in question is an obvious fake.
Cornell Law School defines an arrest warrant as a document issued by a judge or magistrate that authorizes the police to take someone accused of a crime into custody. It has to be issued by the competent authority. The Court of Ages is not a competent authority.
There is no proof of any legal court called the Court of Ages; their website is rife with fake legalese, and no arrest warrant for Biden has been issued.
