Frankfurter was hands-off in the area of business. In the 1956 government case against DuPont, started because DuPont seemed to have maneuvered its way into a preferential relationship with GM, Frankfurter refused to find a conspiracy, and said the Court had no right to interfere with the progress of business. Here again, Frankfurter opposed - and lost out to - the views of the court majority made up of Justices Warren, Black, Douglas and Brennan. Later in his career, Frankfurter's judicial restraint philosophy frequently put him on the dissenting side of ground-breaking decisions taken by the Warren Court to end discrimination.
