What is the highest US court that heard both the Marsh v. Chambers and Clinton v. City of New York cases? 
Marsh v. Chambers: Marsh v. Chambers, 463 U.S. 783 (1983), was a landmark court case in which the Supreme Court of the United States held that government funding for chaplains was constitutional because of the "unique history" of the United States. Clinton v. City of New York: Clinton v. City of New York, 524 U.S. 417 (1998) , is a legal case in which the Supreme Court of the United States ruled that the line-item veto as granted in the Line Item Veto Act of 1996 violated the Presentment Clause of the United States Constitution because it impermissibly gave the President of the United States the power to unilaterally amend or repeal parts of statutes that had been duly passed by the United States Congress.
