The Supreme Court reversed the Fourth Circuit's ruling in a 7–2 decision, determining that since the Cross had stood for decades without controversy, it did not violate the Establishment Clause and could remain standing.[1] The 40 feet (12 m)-tall Peace Cross was constructed in Bladensburg, Maryland by the American Legion with private funding in 1925 to honor the local servicemen that died during World War I.A formal lawsuit was filed by the American Humanist Association, an atheist advocacy group, that argued that the Peace Cross violated the Establishment Clause of the Constitution.[5] Gregory, who dissented again, feared that the ruling could affect thousands of cross-shaped memorials on public lands even though they were built under similar secular purposes as the Peace Cross.[5] Both the Planning Commission and the American Legion petitioned for writs of certiorari from the Supreme Court, asking it to review the Fourth Circuit's decision.[10] The issue of cross-shaped memorials on public lands had been previously heard in Salazar v. Buono in 2010; while the 5–4 majority ruled that the cross could stay, the rationale was heavily divided by the justices, with a total of six different opinions submitted as part of the case.However, how to qualify this under past case law was left as a question, and that if new memorials carrying the cross shape were installed today, they may not be acceptable under the Establishment Clause.[16]: 265 Likewise, the Court credited the planning commission's argument that the modern effects of the cross include historic preservation and improved traffic safety.Breyer quoted his earlier opinion in Van Orden v. Perry (2005) to explain where here, again, a longstanding monument does not pose a real threat to secular tolerance.[16]: 265 Breyer, however, rejected arguments advanced by Justices Kavanaugh and Gorsuch that history and tradition create license to erect new monuments in the old style.
