¶1It is alleged in this petition filed in the Superior Court in 1941 that in 1939 the Commonwealth took from the petitioner for State highway purposes two parcels of land in West Stockbridge; that in 1940 he “duly” filed a petition for the assessment of his damages; that at the trial of that petition the Commonwealth “offered to prove” an alleged agreement referred to as “exhibit 6” for settlement, *593of the damages; that the judge then submitted to the jury the question whether “exhibit-6” (which must have been admitted in evidence) had been filled out “in its present form” when it was signed by the petitioner, to which the jury answered, “Yes”; and that the judge thereupon directed the jury “to assess no damages.” The present petition continues with allegations in effect that the petitioner’s signature to the agreement for settlement, “exhibit 6,” had been obtained by fraudulent representations of an agent acting for the Commonwealth, who had also made fraudulent insertions in the instrument and had affixed a seal to it without the consent or knowledge of the petitioner after the petitioner had signed, and that before the trial of the petition for assessment of damages the Commonwealth had waived and abandoned the agreement, “exhibit 6.” The prayers are that the court declare “exhibit 6” null and void, and that the court decree that the petitioner shall have a right to file a new petition for assessment of his damages. It is plain that this petition is in the nature of a suit in equity for rescission of the alleged agreement relative to damages.
¶2The Commonwealth demurred for the causes, among others, that the petition set forth no ground for relief in equity, and that the petitioner had a full, complete, and adequate remedy upon the petition for assessment of damages. The petitioner appeals from decrees sustaining the demurrer and dismissing the petition.
¶3The decrees were right.
¶4The petition now before us shows that the petitioner had a complete remedy through a petition for assessment of damages for the takings brought under G. L. (Ter. Ed.) c. 79, § 14. He had no need of recourse to equity. At the trial of such a petition an agreement tainted with fraud would not avail the Commonwealth. Gale v. Nickerson, 151 Mass. 428, 432. See Russell v. Barstow, 144 Mass. 130; Preston v. Newton, 213 Mass. 483; Wine v. Commonwealth, 301 Mass. 451, 454. Moreover, the present petition further shows that the petitioner actually brought a proceeding for the assessment of damages which, so far as appears, *594was still pending when the present petition was filed.
¶5It is hardly necessary to add that in so far as the petitioner prays for a decree that he may be allowed to file a new petition for assessment of damages, his rights are governed by the pertinent statute (G. L. [Ter. Ed.] c. 79, particularly §§14 and 16), and the courts have no power to confer upon him the privilege of filing successive petitions or of petitioning at times different from those fixed by statute.
¶6*595In deciding the case upon the points argued we intend no implication as to whether a petition to rescind an agreement for fraud presents a “claim” which may be prosecuted against the Commonwealth within the authority conferred by G. L. (Ter. Ed.) c. 258. See Murdock Parlor Grate Co. v. Commonwealth, 152 Mass. 28; Arthur A. Johnson Corp. v. Commonwealth, ante, 88, 92.
¶7The decrees sustaining the demurrer and dismissing the petition are affirmed. A number of appeals appearing in the record relating to various interlocutory matters, if properly before us at all, have become immaterial and are dismissed.
¶8So ordered.
¶9 In bis brief the petitioner says that bis petition for the assessment of damages went to judgment in favor of the Commonwealth on February 28, 1944, long after the present petition was filed.
