Justice Jackson had a nice way of putting it when he made mistake:
Precedent, however, is not lacking for ways by which a judge may recede from a prior opinion that has proven untenable and perhaps misled others. See Chief Justice Taney, License Cases, 5 How. 504, 12 L.Ed. 256, recanting views he had pressed upon the Court as Attorney General of Maryland in Brown v. State of Maryland, 12 Wheat. 419, 6 L.Ed. 678. Baron Bramwell extricated himself from a somewhat similar embarrassment by saying, 'The matter does not appear to me now as it appears to have appeared to me then.' Andrew v. Styrap, 26 L.T.R.(N.S.) 704, 706. And Mr. Justice Story, accounting for his contradiction of his own former opinion, quite properly put the matter: 'My own error, however, can furnish no ground for its being adopted by this Court * * *.' United States v. Gooding, 12 Wheat. 460, 478, 6 L.Ed. 693. Perhaps Dr. Johnson really went to the heart of the matter when he explained a blunder in his dictionary—' Ignorance, sir, ignorance.' But an escape less self-depreciating was taken by Lord Westbury, who, it is said, rebuffed a barrister's reliance upon an earlier opinion of his Lordship: 'I can only say that I am amazed that a man of my intelligence should have been guilty of giving such an opinion.' If there are other ways of gracefully and good naturedly surrendering former views to a better considered position, I invoke them all.
Anyway, the actual en banc decision is summarized in the first paragraph by Judge Newsom:
Sometimes courts make simple mistakes. And simple mistakes call for simple fixes. Just so here. In United States v. Sparks, we held that a suspect who “abandons” his privacy or possessory interest in the object of a search or seizure suffers no “injury”—and thus has no standing—in the Article III sense, and, accordingly, that an argument asserting the suspect’s abandonment is jurisdictional, nonwaivable, and subject to sua sponte consideration. 806 F.3d 1323, 1341 n.15 (11th Cir. 2015). Sitting en banc, we now overrule Sparks and hold, to the contrary, that a suspect’s alleged abandonment implicates only the merits of his Fourth Amendment challenge—not his Article III standing—and, accordingly, that if the government fails to argue abandonment, it waives the issue
