"You were right the first time. Amicus is signular. Aimici is plural."

Thanks. . . Yes, the brief reads. . .'Amici Brief 032305(Final.PDF) . . .more than forty pages long. . .'plural for sure; but 'brief' not ;^) (Blog had it as Amicus - referencing (mistakenly) entire document as 'one', I guess.)
