In this appeal of an order denying postconviction relief after evidentiary hearing, for which counsel was appointed, the public defender has moved to withdraw as appellate counsel and filed a supporting brief pursuant to Anders v. California, 386 U.S. 738, 87 S.Ct. 1396, 18 L.Ed.2d 493 (1967), and State v. Herzig, 208 So.2d 619 (Fla. 1968). The authority for appointing counsel to handle postconviction matters stems from the due process clause of the Fifth Amendment of the United States Constitution, not the Sixth Amendment right to counsel. See Schneelock v. State, 665 So.2d 1063 (Fla. 4th DCA 1995), rev. denied, 672 So.2d 543 (Fla. 1996); Graham v. State, 372 So.2d 1363, 1365-66 (Fla. 1979). Accordingly, it is not necessary to follow the procedure set forth in Anders before seeking to withdraw from appeals of orders denying postconviction relief. See generally Ostrum v. Department of Health and Rehabilitative Servs. of Fla., 663 So.2d 1359 (Fla. 4th DCA 1995) (determining Anders procedures should not attend appellate consideration of appeal from final order terminating parental rights, where right to counsel does not arise under Sixth Amendment).
