Pedro Gonzales-Perez appeals from the district court’s 1 dismissal of his civil rights claims against the Iowa State Penitentiary hearing officer who conducted disciplinary hearings without affording Gonzales-Perez an interpreter. We affirm.
I.
Gonzales-Perez is a Spanish-speaking Cuban native who came to the United States in the early 1980s at the age of 34. He was first incarcerated in the Iowa State Penitentiary (ISP) system in October 1993, where he remains. During his stay in the ISP system, Gonzales-Perez has faced numerous disciplinary hearings, 2 most of which resulted in the revocation of good time credits. Defendant Charles Harper was the Administrative Law Judge presiding over disciplinary hearings in the ISP system during the relevant time periods. 3 Gonzales-Perez received the assistance of an interpreter at a number of his disciplinary hearings, particularly during his early incarceration. At other hearings, he neither requested nor received the assistance of an interpreter. He knew how to request an interpreter, as evidenced by a request during his third disciplinary hearing in April 1994. It is undisputed that Gonzales-Perez received an interpreter at all hearings for which he requested one. 4 ISP has provided a Spanish interpreter at all of Gonzales-Perez’s disciplinary hearings since April 1997.
Gonzales-Perez has filed grievances within the ISP disciplinary process related *636 to various disciplinary hearings but has never filed a grievance based on the lack of a Spanish interpreter. Further, Gonzales-Perez has never pursued state post conviction relief related to any of the disciplinary hearings. See Iowa Code § 822.2(6) (permitting a challenge to revocation of good time credits in the Iowa courts).
Gonzales-Perez filed this 42 U.S.C. § 1983 (1994) claim in 1996, claiming that the failure to provide a Spanish interpreter at all of his disciplinary hearings violated his constitutional rights to due process and equal protection. Gonzales-Perez also sought injunctive relief, requesting an order requiring the ISP to provide a Spanish interpreter at all future hearings. The case was referred to a magistrate judge
5
pursuant to 28 U.s.c. § 636(b)(1)(B), who held an evidentiary hearing on April 23, 1998. The magistrate judge thereafter filed a detailed and comprehensive report and recommendation with the district court, recommending that the case be clis-missed. The magistrate judge found that Gonzales-Perez was proficient enough in English to understand the nature of the disciplinary proceedings against him, was able to respond to them, and that a Spanish interpreter was reasonably available when he so requested. (
The district court agreed with the magistrate judge's recommendation that the case should be dismissed. The district court found that Gonzales-Perez's § 1983 claims based on the Due Process Clause were Heck-barred because they necessarily implicated the invalidity of his disciplinary sentences, and he had not met the prerequisite of establishing that those sentences had been invalidated. See Heck v. Humphrey,
II.
The parties dispute whether the district court appropriately reviewed the record following Gonzales-Perez's objections to the magistrate judge's report and recommendation. When a party timely objects to a magistrate judge's report and recommendation, the district court is required to make a de novo review of the record related to the objections, which requires more than merely reviewing the report and recommendation. See 28 U.S.C. § 636(b)(1); see also Jones v. Pillow,
The district court stated that "[u]pon de novo review of the record of plaintiff's case, the court agrees it must be dismissed." (Add, at 3.) The only evidence
*637
Gonzales-Perez raises to establish that the district court did not perform a de novo review is its statement at the end of its order that “[bjeeause the court resolves plaintiffs claims on these bases, the court does not address the parties’ other arguments.”
(Id.
at 13.) However, there is a big difference between addressing arguments and reviewing the record. Further, the district court dismissed the equal protection claims on the merits, indicating that the court did in fact review the entire record de novo.
(Id.
(“Plaintiffs claimed equal protection violation also is without merit. There is no ‘English only’ policy, and defendants did not discriminate against plaintiff.”).) Gonzales-Perez therefore fails to make a prima facie case that the district court did not properly review the record.
See Jones,
III.
To successfully bring a § 1983 claim, Gonzales-Perez must establish the “deprivation of a constitutional right by an individual acting under ‘color of state law.’ ”
Woodis v. Westark Cmty. Coll.,
We need not revisit
Moorman
today because we hold that even if Gonzales-Perez had a liberty interest in good time credits earned within the ISP system, the defendant did not violate his right to due process in revoking them. “Prison disciplinary proceedings are not part of a criminal prosecution, and the full panoply of rights due a defendant in such proceedings does not apply.”
Wolff,
The district court dismissed Gonzales-Perez’s equal protection claims on the merits. It is not altogether clear whether Gonzales-Perez appeals the equal protection issue. In any ’event, he has offered no evidence to establish that the district court’s ruling on the merits was clearly erroneous.
Weir v. Nix,
IV.
We affirm the judgment of the district court.
Notes
. The Honorable Ronald E. Longstaff, Chief Judge, United States District Court for the Southern District of Iowa.
. Gonzales-Perez received 81 disciplinary reports between October 1993 and December 1997.
. The suit was originally brought against Gerardo Acevedo, ISP’s former warden, and against Harper. Early in the case the district court dismissed the suit against Acevedo as frivolous, leaving Harper as the sole defendant.
. Gonzales-Perez’s attorney conceded this point during oral argument.
. The Honorable Richard W. Peterson, then a United States Magistrate Judge for the South-em District of Iowa, now retired.
. We may affirm the district court on any basis supported by the record.
