What follows is an opinion from the Supreme Court of the United States. Your task is to determine the bases on which the Supreme Court rested its decision with regard to the legal provision that the Court considered in the case. Consider "judicial review (national level)" if the majority determined the constitutionality of some action taken by some unit or official of the federal government, including an interstate compact. Consider "judicial review (state level)" if the majority determined the constitutionality of some action taken by some unit or official of a state or local government. Consider "statutory construction" for cases where the majority interpret a federal statute, treaty, or court rule; if the Court interprets a federal statute governing the powers or jurisdiction of a federal court; if the Court construes a state law as incompatible with a federal law; or if an administrative official interprets a federal statute. Do not consider "statutory construction" where an administrative agency or official acts "pursuant to" a statute, unless the Court interprets the statute to determine if administrative action is proper. Consider "interpretation of administrative regulation or rule, or executive order" if the majority treats federal administrative action in arriving at its decision.Consider "diversity jurisdiction" if the majority said in approximately so many words that under its diversity jurisdiction it is interpreting state law. Consider "federal common law" if the majority indicate that it used a judge-made "doctrine" or "rule; if the Court without more merely specifies the disposition the Court has made of the case and cites one or more of its own previously decided cases unless the citation is qualified by the word "see."; if the case concerns admiralty or maritime law, or some other aspect of the law of nations other than a treaty; if the case concerns the retroactive application of a constitutional provision or a previous decision of the Court; if the case concerns an exclusionary rule, the harmless error rule (though not the statute), the abstention doctrine, comity, res judicata, or collateral estoppel; or if the case concerns a "rule" or "doctrine" that is not specified as related to or connected with a constitutional or statutory provision. Consider "Supreme Court supervision of lower federal or state courts or original jurisdiction" otherwise (i.e., the residual code); for issues pertaining to non-statutorily based Judicial Power topics; for cases arising under the Court's original jurisdiction; in cases in which the Court denied or dismissed the petition for review or where the decision of a lower court is affirmed by a tie vote; or in workers' compensation litigation involving statutory interpretation and, in addition, a discussion of jury determination and/or the sufficiency of the evidence.

Opinion:
MASSACHUSETTS v. WESTCOTT
No. 75-1775.
Argued January 17, 1977
Decided May 23, 1977
Per Curiam.
Respondent Westcott was arrested for violating a Massachusetts statute that prohibits nonresidents of the Commonwealth of Massachusetts from dragging for fish by beam or otter trawl in Vineyard Sound during July, August, and September. After he was found guilty, he pursued his right to de novo review and filed a motion to dismiss the complaint. The Massachusetts Supreme Judicial Court granted direct appellate review and ordered the complaint dismissed on the ground that the statute violated the Privileges and Immunities Clause of the United States Constitution, Art. IV, § 3, cl. 2. 344 N. E. 2d 411. We granted certiorari. 429 U. S. 815 (1976).
Our decision today in Douglas v. Seacoast Products, Inc., ante, p. 265, suggests that there may be a statutory basis to provide respondent the relief he seeks, thereby making it unnecessary to decide the constitutional. question presented. Douglas holds that federal law pre-empts the States from denying vessels that are federally enrolled and licensed for the fisheries the right to fish in state waters on the same terms as state residents. Respondent’s vessel is federally enrolled and licensed “to be employed in carrying on the mackerel fishery,” .the same license that was held by appellees in Douglas. In accordance with our longstanding principle of deciding constitutional questions only when necessary, Hagans v. Lavine, 415 U. S. 528, 543 (1974); Ashwander v. TVA, 297 U. S. 288, 347 (1936) (Brandeis, J., concurring), we decline to decide the privileges and immunities question presented in this case, and vacate the judgment and remand the case for further consideration in light of Douglas. See McGoldrick v. Compagnie Generale Transatlantique, 309 U. S. 430 (1940).
It is so ordered.
Justice Rehnquist concurs in the judgment on the authority of Douglas v. Seacoast Products, Inc., ante, p. 265.
The Act of Feb. 20, 1923, c. 35, 1923 Mass. Acts 17, as amended by the Act of Mar. 13, 1962, c. 219,1962 Mass. Acts 107:
“It shall be unlawful during the months of July, August and September for any person who has not been a legal resident of this commonwealth during the preceding year to use beam or otter trawls to drag for fish in that part of the waters of Vineyard Sound lying in the towns of Chilmark, Gay Head and Gosnold, and included between an imaginary line running from the extreme western point of Gay Head to the extreme western point of Nashawena island and another imaginary line running from Cape Higgon to Tarpaulin Cove Light. Violation of this act shall be punished by a fine of not less than five hundred nor more than one thousand dollars.”
The fact that respondent holds such a license has been ascertained from the records of the Merchant Vessel Documentation Division of the Coast Guard. These records may be judicially noticed. See, e. g., Bowles v. United States, 319 U. S. 33 (1943); Tempel v. United States, 248 U. S. 121 (1918); Jones v. United States, 137 U. S. 202 (1890); cf. Fed. Rule Evid. 201 (b) (“A judicially noticed fact must be one not subject to reasonable dispute in that it is . . . capable of accurate and ready determination by resort to sources whose accuracy cannot reasonably be questioned”). The parties were given, an opportunity to comment on the propriety of our taking notice of the license, and both sides agreed that we could properly do so. See supplemental briefs filed by the parties.
