Shannon Charles Ferguson, Louisiana prisoner # 214807, appeals the district court’s denial and dismissal with prejudice of his 42 U.S.C. § 1983 complaint, which it construed as a 28 U.S.C. § 2254 petition. While Ferguson argues that the district court erred in construing his civil rights complaint as a habeas petition because he is not challenging his conviction or confinement, his claim that his 1996 seven-year sentence, no matter how served, was over in seven years is essentially an argument that he should receive credit towards his 1996 conviction for his time spent on good time parole. The specific characterization of Ferguson’s claim is not critical, however, because Ferguson has not demonstrated a constitutional violation. See Thomas v. Torres, 717 F.2d 248, 248-49 (5th Cir. 1983).

When a prisoner is released because of a reduction of his sentence, “he shall be released as if released on parole.” LaRev. Stat. 15:571.5(A)(1). If a person’s parole is revoked for a violation of the terms of parole, the person shall be recommitted to the department of corrections “for the remainder of the original full term.” Id. at 15:571.5(C); see Howard v. Louisiana Bd. of Probation and Parole, 589 So.2d 534, 534-36 (La.App. 1991), writ denied, 590 So.2d 87 (La. 1991); see also Bancroft v. Louisiana Dept. of Corrections, 635 So.2d 738, 740 (La.App. 1994). There is no federal constitutional right to the reduction of a sentence of a parole violator for time spent on parole. See Morrison v. Johnson, 106 F.3d 127, 129 n. 1 (5th Cir. 1997); Newby v. *356 Johnson, 81 F.3d 567, 569 (5th Cir. 1996). Accordingly, Ferguson’s challenge to his sentence computation is without merit.

Ferguson correctly argues that, because he never received a copy of the magistrate judge’s report, the district court erred in finding that he filed no objections to the magistrate judge’s report. The error was, for the reasons noted above, harmless. See McGill v. Goff, 17 F.3d 729, 731 (5th Cir. 1994), overruled on other grounds, Kama Reins. Corp. v. Congressional Mortgage Co., 20 F.3d 1362, 1373-74 (5th Cir. 1994). As Ferguson has failed to show that the defendants violated his constitutional rights, the district court’s judgment is AFFIRMED.
