On June 22, 1970, the defendant was arrested and charged with violating G. L. c. 264, § 5, as amended by St. 1959, c. 59, § 4, to wit: treating contemptuously the flag of the United States. The defendant was tried, convicted and sentenced to two months in the house of correction, together with a fine of $100. His exception to the denial of his motion to dismiss is based, inter alla, on the contention that the statute is unconstitutionally vague. In view of our holding below we do not reach the other grounds argued by the defendant for reversal. The pertinent facts are as follows. At the time of his arrest, the defendant was wearing an outer jacket on the back of which was sewn the flag of the United States, upside down. Testimony indicated that the defendant was *196peaceful at the time of his arrest. The defendant’s motion for dismissal was denied before trial. The Supreme Court of the United States has spoken on this issue, most recently, in the case of Smith v. Goguen, 415 U. S. 566 (1974). In that case, the sheriff of Worcester County, Massachusetts, appealed from a judgment of the United States Court of Appeals for the First Circuit holding the contempt provision of the Massachusetts flag misuse statute unconstitutionally vague and overbroad. The Supreme Court of the United States affirmed on the vagueness ground but did not reach overbreadth or other First Amendment grounds. The evidence in the Goguen case was that the defendant wore a small version of the United States flag approximately four by six inches sewn on the seat of his trousers. Although we might be inclined to agree with the reasoning in the dissenting views of Chief Justice Burger, Justice Blackmun and Justice Rehnquist, “we do not write on a clean slate.” We must follow the mandate of the majority opinion in the Goguen case and thus we reverse the conviction of the defendant.

Exceptions sustained.

Kaplan, J., concurs in the result.
