In 1976, William Lee Thompson was sentenced to death for kidnaping, raping and murdering Sally Iverson. Thompson's case then traveled for many years through the state and federal courts on different prayers for relief. Thompson most recently filed an appeal from the denial of his motion for post-conviction relief and a habeas petition to the Florida Supreme Court. On 13 April 2000, the Florida Supreme Court affirmed the trial court's summary denial for relief and also denied habeas relief. Thompson v. State, 759 So. 2d 650, 668 (Fla.2000). Thompson's petition for rehearing was denied on 13 June 2000.

Exactly one year after his exhausted claims became final in the Florida courts — 13 June 2001 — Thompson filed a petition for habeas relief in the federal courts. In addition to many exhausted claims, Thompson presented two unexhausted claims to the district court. One unexhausted claim related to the recent passage of a Florida statute prohibiting the execution of mentally retarded people. Fla. Stat. § 921.137 (2001). That statute was enacted only one day before Thompson filed his federal habeas petition; and he claims, no opportunity existed to challenge the statute in state court before his federal petition was due under the Antiterrorism and Effective Death Penalty Act of 1996 (AEDPA), 28 U.S.C. § 2244. The second unexhausted claim advanced an argument that execution of mentally retarded people violated the U.S. Constitution.1

Thompson moved the district court to hold the federal habeas proceedings in abeyance pending exhaustion of his two unexhausted claims in state court. Thompson recognized his petition was one which impermissibly "mixed" exhausted and unexhausted claims. But Thompson argued he had no choice except to file a mixed petition to meet the one-year filing deadline of AEDPA and to preserve review of the exhausted claims.

To avoid more delay before reaching finality, the district court denied Thompson's motion to stay the habeas proceedings. The district court presented Thompson with an election of remedies: abandon the unexhausted claims and proceed on the exhausted claims, or suffer dismissal of the entire petition as a mixed petition. When the district court offered the alternative remedies, it also noted the possibility that the constitutional complaint against executing mentally retarded people might later be a permissible second or successive habeas petition. Thompson, all the while represented by counsel, made no affirmative election of the remedies offered by the district court; and the district court dismissed without prejudice the mixed petition. Thompson argues on appeal that the district court abused its discretion by refusing to stay the proceedings pending exhaustion of all his claims in state court.2

Even if we assume, for the sake of discussion, that the district court had discretion not to dismiss the mixed petition, we conclude there was no abuse of that discretion.3 This litigation had been going on for decades. In addition, a district court could reasonably believe that these unexhausted claims might properly be brought later in a second or successive petition.4 Given the nature of the unexhausted claims, it was especially reasonable to place this habeas petitioner — who was represented by counsel — in the position of choosing between dismissal of his entire petition or voluntary dismissal of his unexhausted claims, claims which might not have been forfeited anyway. There was no abuse of the district court's discretion.

AFFIRMED.
