“This court has emphasized repeatedly that relief under G. L. c. 211, § 3, is extraordinary.” Pandey v. Roulston, 419 Mass. 1010, 1011 (1995). It applies only “in exceptional circumstances and where necessary to protect substantive rights in the absence of an alternative, effective remedy.” Id., quoting Soja v. T.P. Sampson Co., 373 Mass. 630, 631 (1977). “Where a petitioner can raise his claim in the normal course of trial and appeal, relief will be denied.” Foley v. Lowell Div. of the Dist. Court Dep’t, 398 Mass. 800, 802 (1986).

Here, Votta claims that review under G. L. c. 211, § 3, is warranted because he has discovered new evidence relevant to his conviction.^[1] The proper means of raising such a claim, however, is a motion for a new trial pursuant to Mass. R. Grim. R 30, 378 Mass. 900 (1979). Votta claims that such a motion would be futile, because the “newly discovered evidence is of the same texture as the evidence objected to by the prosecutor and sustained by the trial judge,” and “it is very unlikely that the original trial judge will allow new cumulative evidence.” Votta’s fear that his motion will be unsuccessful does not establish that he has no other adequate remedy for purposes of G. L. c. 211, § 3. He remains free to file such a motion.

Judgment affirmed.
