Now Mr. Haynesworth, 46, is asking for full exoneration on all of the rape convictions, although DNA from the other two cases is not available. But the circumstantial evidence supporting Mr. Haynesworth’s claims of innocence is so powerful that along with his own lawyers, the prosecutors from both jurisdictions where the rapes occurred support his efforts, as well as the attorney general for the commonwealth, Kenneth T. Cuccinelli.

With no one arguing against exoneration, most judges would be expected to congratulate Mr. Haynesworth on his new life, perhaps with an apology as well, and send him into daylight and freedom. But in July, a three-judge panel of the Court of Appeals of Virginia said, in essence, “Not so fast.” The court called for additional briefs in the case, which will be heard again on Tuesday by all of the judges of the court.

It is a move that has left legal experts astonished. “It’s very rare for a court to set a case for argument when all the parties are agreed,” said Stephen J. Schulhofer, an expert in criminal justice at New York University law school, adding that “it’s essentially unheard of” for a court to take matters into its own hands, instead of appointing a special advocate to argue on behalf of the interests that they believe are unrepresented.

It is a case, then, that might seem quirky, even unique. But experts like Professor Schulhofer say the case raises broader questions about the lengths that defendants must sometimes go to clear their names, and even raises fundamental questions about the administration of justice. “What I worry about is, if Haynesworth is having trouble getting his conviction set aside, what kind of judicial relief is available to your run-of-the-mill case where your arguments are not quite so slam dunk?”

Mr. Haynesworth’s fight for freedom began in 2009, when the state’s department of forensic evidence tested the DNA from the first rape as part of a broad review of old case files. The results cleared Mr. Haynesworth of that rape, and he received an exoneration on that charge later that year. Mr. Haynesworth’s lawyers at the Mid-Atlantic Innocence Project and the Innocence Project in New York, along with private lawyers, filed legal papers for Mr. Haynesworth with the Court of Appeals of Virginia to get a writ of actual innocence on the remaining convictions. Subsequent testing of the DNA from the trial in which Mr. Haynesworth was acquitted eliminated him — and again implicated Mr. Davis.
