As this court has already explained—in an appeal brought by Mr. El Malik—"[t]he remedy of mandamus is a drastic one, to be invoked only in extraordinary situations." El Malik v. Shinseki, No. 2011-7201, 2012 WL 833663, at *3 (Fed. Cir. Feb. 13, 2012) ; see also Lamb v. Principi, 284 F.3d 1378, 1382 (Fed. Cir. 2002) ("To obtain mandamus, the petitioner must show (1) that he has a 'clear and indisputable right' to the writ and (2) that he has no alternative way to obtain the relief sought." (citation omitted)).
