What follows is an opinion from the Supreme Court of the United States. Your task is to identify the disposition of the case, that is, the treatment the Supreme Court accorded the court whose decision it reviewed. The information relevant to this variable may be found near the end of the summary that begins on the title page of each case, or preferably at the very end of the opinion of the Court. For cases in which the Court granted a motion to dismiss, consider "petition denied or appeal dismissed". There is "no disposition" if the Court denied a motion to dismiss.

Opinion:
ATLANTIC COAST LINE RAILROAD CO. v. ERIE LACKAWANNA RAILROAD CO. et al.
No. 71-107.
Argued April 17-18, 1972
Decided May 15, 1972
Devereux Milburn argued the cause for petitioner. With him on the briefs were Louis L. Stanton, Jr., Jerome L. Getz, and Frank G. Kurka.
E. Barrett Prettyman, Jr., argued the cause for respondents. With him on the brief for respondent Erie Lackawanna Railroad Co. were Timothy J. Bloomfield and Lloyd W. Roberson.
Per Curiam.
We granted certiorari to review the judgment of the Court of Appeals for the Second Circuit, 442 F. 2d 694 (1971), affirming the judgment of the District Court for the Southern District of New York, 315 F. Supp. 357 (1970). 404 U. S. 909 (1971). We agree that in this noncollision admiralty case the District Court properly dismissed petitioner’s third-party complaint for contribution against respondent Erie on the authority of Halcyon Lines v. Haenn Ship Corp., 342 U. S. 282 (1952). The judgment of the Court of Appeals is therefore
Affirmed.
