A federal appeals court reviewing evidence at Guantanamo Bay compared a Bush administration legal argument to one made by a hapless, dimwitted character in a 19th-century nonsense poem by Lewis Carroll.

The U.S. Court of Appeals for the D.C. Circuit cited the 1876 poem “The Hunting of the Snark” in ruling that the military improperly labeled a Chinese Muslim as an enemy combatant. The ruling was issued last week, but an unclassified version of the opinion was released only Monday.
