Petitioner Kim Kohler appeals the district court’s denial of relief on his 28 U.S.C. § 2254 petition. On May 5, 2000, a panel of this court remanded Kohler’s case for an evidentiary hearing on the question whether Kohler’s trial counsel, Salvadore Panzeca, rendered ineffective assistance by failing to subpoena codefendant Richard Allnet to testify at Kohler’s trial. See Kohler v. Cain, 214 F.3d 1350 (5th Cir. 2000). The evidence presented at the evidentiary hearing revealed that Panzeca attempted to obtain Allnet’s presence, but that Allnet’s attorney refused to permit Allnet to testify. At that point, Panzeca was ethically barred from pursuing the matter further. See La.Code Prof’l Responsibility EC 7-18, DR 7-104(A)(l) (1980) (“[A] lawyer should not communicate on the subject matter of the representation of his client with a person he knows to be represented in the matter by a lawyer[.]”).
Panzeca was also aware that each of the four codefendants involved in the incident for which Kohler was convicted were “pointing fingers” at each other. As such, he was concerned that Allnet would have made a “damaging witness” and would have “turned state’s evidence” at trial. This concern was supported by a transcript of Allnet’s grand jury testimony, which was in Panzeca’s possession prior to trial. In that transcript, Allnet made incriminating statements as to Kohler’s active involvement in the crime.
After our thorough review of the evidentiary hearing record, we conclude that Panzeca attempted to obtain Allnet’s presence on the request of Kohler and also made a strategic decision, based upon a review of the grand jury transcript, not to call Allnet as a witness at Kohler’s trial. Accordingly, his conduct did not constitute deficient performance. See Strickland v. Washington, 466 U.S. 668, 687, 104 S.Ct. 2052, 80 L.Ed.2d 674 (1984).
Kohler also asserts that he did not receive a fair evidentiary hearing before the district court because Allnet did not testify at that hearing. We disagree. As an initial matter, Kohler did not subpoena Allnet for the hearing. Second, to the extent Kohler is asserting that his hearing attorney failed to subpoena Allnet, there is no constitutional right to counsel in habeas proceedings, and therefore, Kohler cannot claim ineffective assistance of counsel in such proceedings. See Irving v. Hargett, 59 F.3d 23, 26 (5th Cir.1995); Johnson v. Hargett, 978 F.2d 855, 859 (5th Cir.1992).
Finally, within his appellate brief, Kohler refers to various constitutional violations other than his ineffective-assistance claim. These assertions include that he was denied his right to compulsory process, that the State improperly sanctioned perjured testimony from one of its witnesses, and that Panzeca prevented Kohler from testifying at trial. To the extent that any of these are issues raised separately from Kohler’s ineffective-assistance claim, the district court did not grant a certificate of appealability on those issues, nor did Kohler request one. Accordingly, those issues are not properly before this court. See Lackey v. Johnson, 116 F.3d 149, 151— *79352 (5th Cir.1997) (limiting appellate review to only those issues specified in the certificate of appealability); cf. United States v. Kimler, 150 F.3d 429, 431 (5th Cir.1998).
For the foregoing reasons, the district court’s judgment is AFFIRMED.
Pursuant to 5th Cir. R. 47.5, the court has determined that this opinion should not be published and is not precedent except under the limited circumstances set forth in 5th Cir. R. 47.5.4.
