What is the test for a habeas application?

Sash was released on November 22, 2004, having served 17 days more than he contends the law allows. He must still complete an eight-year term of supervised release, which he argues should be reduced because of the excess imprisonment he has suffered. See 28 U.S.C. 2243 (district court shall dispose of habeas applications "as law and justice require"). The United States District Court for the Eastern District of New York (Garaufis, J.) denied Sash's petition in a thoughtful and thorough opinion. See Sash v. Zenk, 344 F.Supp.2d 376 (E.D.N.Y.2004).
