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:
UNITED STATES ex rel. LEE KUM HOY et al. v. MURFF, DISTRICT DIRECTOR, IMMIGRATION AND NATURALIZATION SERVICE.
No. 32.
Argued November 21, 1957.
Decided December 9, 1957.
Benjamin Gim argued the cause for petitioners. With him on the brief was Edward J. Ennis.
John F. Davis argued the cause for respondent. With him on the brief were Solicitor General Rankin, Assistant Attorney General Olney, Acting Assistant Attorney General McLean and Beatrice Rosenberg.
Per Curiam.
In view of the representation in the Solicitor General’s argument at the Bar that the blood grouping test requirement here involved is presently and has been for some time applied without discrimination “in every case, irrespective of race, whenever deemed necessary,” and in view of our remand of the case, we need not now pass upon the claim of unconstitutional discrimination.
It appearing that the blood grouping tests made herein were in some respects inaccurate and the reports thereof partly erroneous and conflicting, the judgments heretofore entered are vacated and the case is remanded to the District Court with directions that the hearings before the Special Inquiry Officer or a Board of Special Inquiry be reopened, so that new, accurate blood grouping tests may be made under appropriate circumstances, and that relevant evidence may be received as offered on the issues involved. The excludability of petitioners remains to be determined upon those proceedings.
