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:
WESTBROOK v. ARIZONA.
No. 1250,
Misc.
Decided May 2, 1966.
W. Edward, Morgan for petitioner.
Darrell F. Smith, Attorney General of Arizona, and Paul G. Rosenblatt, Assistant Attorney General, for respondent.
Per Curiam.
The motion for leave to proceed in forma pauperis and the petition for a writ of certiorari are granted. Although petitioner received a hearing on the issue of his competence to stand trial, there appears to have been no hearing or inquiry into the issue of his competence to waive his constitutional right to the assistance of counsel and proceed, as he did, to conduct his own defense. “The constitutional right of an accused to be represented by counsel invokes, of itself, the protection of a trial court, in which the accused — whose life or liberty is at stake — is without counsel. This protecting duty imposes the serious and weighty responsibility upon the trial judge of determining whether there is an intelligent and competent waiver by the accused.” Johnson v. Zerbst, 304 U. S. 458, 465; Carnley v. Cochran, 369 U. S. 506.
From an independent examination of the record, we conclude that the question whether this “protecting duty” was fulfilled should be re-examined in light of our decision this Term in Pate v. Robinson, 383 U. S. 375. Accordingly, the judgment of the Supreme Court of Arizona is vacated and the case is remanded to that court for proceedings not inconsistent herewith.
It is so ordered.
