In the Matter of Agnes Scranton, Appellant,
v.
Supreme Court of the State of New York et al., Respondents. (Two Proceedings.)
Court of Appeals of the State of New York.
Argued February 11, 1975.
Decided February 27, 1975.
Eleanor Jackson Piel for appellant.
Richard H. Kuh, District Attorney (Jonathan Lovett and Lewis R. Friedman of counsel), respondent pro se.
Louis J. Lefkowitz, Attorney-General (Samuel A. Hirshowitz and David H. Berman of counsel), for Justices of Supreme Court, respondents.

*705MEMORANDUM.
The judgments of the Appellate Division should be affirmed, without costs. A claim of a denial of a speedy trial is not cognizable in an application pursuant to CPLR article 78 for a judgment prohibiting a District Attorney and the Justices of the Supreme Court from proceeding on an indictment. (Matter of Watts v. Supreme Ct. of State of N. Y., 28 N Y 2d 714; Matter of Lee v. County Ct. of Erie County, 27 N Y 2d 432, 437; Matter of Blake v. Hogan, 25 N Y 2d 747.) While a double jeopardy claim may be raised in a prohibition proceeding (Matter of State of New York v. King, 36 N Y 2d 59, at p. 64; *706Matter of Kraemer v. County Ct. of Suffolk County, 6 N Y 2d 363), this petition should nevertheless be denied. The petitioner was not placed in jeopardy despite the fact that three jurors had been sworn before a mistrial was declared. (CPL 40.30, subd. 1, par. [b].)
Judgments affirmed.
