JUDGMENT
PER CURIAM.This appeal was considered on the record from the United States District Court for the District of Columbia and on the brief and supplement thereto filed by appellant. See Fed. R.App. P. 34(a)(2); D.C.Cir. Rule 34(j). Upon consideration of the foregoing and the motion for appointment of counsel, it is
ORDERED that the motion for appointment of counsel be denied. In civil cases, appellants are not entitled to appointment of counsel when they have not demonstrated any likelihood of success on the merits. It is
FURTHER ORDERED AND ADJUDGED that the district court’s order filed March 7, 2011, dismissing the complaint pursuant to 28 U.S.C. §§ 1915(e)(2)(B)(ii) and 1915A(b)(l), be affirmed. Appellant’s damages claim is barred by Heck v. Humphrey, 512 U.S. 477, 486-87, 114 S.Ct. 2364, 129 L.Ed.2d 383 (1994), because a judgment on his claim would necessarily imply the invalidity of his sentence, which has not been invalidated in a prior proceeding.
Pursuant to D.C. Circuit Rule 36, this disposition will not be published. The Clerk is directed to withhold issuance of the mandate herein until seven days after resolution of any timely petition for rehearing or petition for rehearing en banc. See Fed. R.App. P. 41(b); D.C.Cir. Rule 41.
