"It is a maxim that equity regards the substance rather than the form." ( Lord v. Lord, 35 Haw. 26, 39.) Hence, "* * * whether a suit is one against a State is to be determined, not by the fact of the party named as a defendant on the record, but by the result of the judgment or decree which may be entered * * *." ( Minnesota v. Hitchcock, 185 U.S. 373, 387).
