Pub. L. 114-38 (28 U.S. Code § 1 - Number of justices)
The Supreme Court of the United States shall consist of a Chief Justice of the United States and eight associate justices, any six of whom shall constitute a quorum.
(June 25, 1948, ch. 646, 62 Stat. 869.)

“full nine-Member Court” seems to me to be an attempt to disparage the legitimacy of the Court’s decision.
