Considering that the party seeking the injunction bears the burden of prrof and must establish irreparable harm, a strong likelihood of prevailing on the merits, etc., I'd be pretty bent out of shape if some partisan hack granted the injunction solely on the basis of an out of court statement (aka Hearsay). Whether the hearsay was offered into the record as an exception, exemption or bc no judge in the country knows the rough ridin' hearsay rules is irrelevant. There's no way it's sufficient evidence to obtain an injunction.
