1971
Clay, aka Ali v. United States
Muhammad Ali refused induction into the armed forces in 1967 on religious grounds and was convicted of draft evasion. His local board had denied him conscientious-objector status without stating why. The Justice Department's own letter to the appeal board had offered three separate grounds for denying the claim, and by the time the case reached the Supreme Court the Court could not determine which of the three the board had actually relied on. Unable to review a decision that gave no reasons, the Court reversed the conviction unanimously, 8-0.
Why it still matters
It is not, on the record, a case where the law agreed Ali was right to refuse. It is a case where an unreasoned decision by a government body could not survive review -- a narrower and in some ways more durable principle than vindication would have been.
The old rule
A conscientious-objector claim could be denied by a local or appeal board without the board stating which of the statutory grounds for denial it relied on, leaving a reviewing court unable to test the board's reasoning against the record.
The legal hinge
Per curiam, and short: since the government's letter to the appeal board offered three possible grounds for denying the exemption and nothing in the record showed which one the board adopted, the conviction could not stand. The Court did not reach whether Ali's objection was in fact sincere or whether it satisfied the substantive test for conscientious-objector status under the framework then in force.
What people believe
The Supreme Court ruled that Ali's religious objection to the war was valid and vindicated him.
What actually happened
The Court ruled that the appeal board's unexplained denial could not be reviewed, and reversed on that ground alone. Whether Ali's objection met the substantive legal test was never definitively answered by the Court.
What it cost
Ali did not fight for close to four years during what would have been his athletic prime, was stripped of his heavyweight title, and lost his boxing license in most states while the case proceeded -- won unanimously, four years after the conviction, on a ground that turned on the board's paperwork rather than his belief. One secondary account (Woodward & Armstrong, The Brethren) reports that Justice Harlan initially voted to affirm the conviction and changed his vote after a law clerk gave him The Autobiography of Malcolm X to read; this is not confirmed by any primary record, as Supreme Court conference votes are not public.
Who captured it
Ali recovered his boxing license and title shot, but not the years. The broader effect ran to conscientious-objector claimants generally: a board denying the status now had to say why, or risk exactly this result.
If it had gone the other way
A differently drafted denial letter, one that had committed clearly to a single ground, likely survives this exact challenge -- the flaw the Court found was procedural rather than substantive. What is not contingent is the four years lost while the case worked through the courts; no version of a faster or cleaner win returns them.
