delivered the opinion of the Court.
The Territorial Legislature of Alaska, provided for the licensing of commercial fishermen in territorial waters, imposing a $5 license fee on resident fishermen and a $50 fee on nonresidents. Alaska Laws, 1949, c. 66. The Alaska Fishermen’s Union and its Secretary-Treasurer, on behalf of some 3,200 nonresident union members, brought this action in the District Court of the Territory ' to enjoin the Tax Commissioner from collecting the license fee from nonresidents. Plaintiffs contended that the Territorial Legislature was without power under the Organic Act to pass the statute, that the exaction complained of. unconstitutionally burdens interstate commerce, and that it is an abridgment of the privileges and immunities of citizens of other States forbidden by Art. IV, § 2 of the Constitution and by the Fourteenth Amendment. After trial, |,he District Court concluded that the differential between resident and nonresident fees rests . on substantial differences bearing a fair and reasonable relation to the objects of the legislation, and upheld the statute.
Here, for the first time, petitioner questioned the standing of respondent únion and its Secretary-Treasurer to . maintain this suit. • To remove the matter from controversy, respondent moved for leave to add as parties plain *417 tiff two of its members, nonresidents of Alaska and subject to the statutory exaction. Rule 21 of the Federal Rules of Civil Procedure authorizes the addition of parties “by order of the court on motion of any party or of its own initiative at any stage of the action and on such terms as are just.” The original plaintiffs alleged without contradiction that they were authorized by the nonresident union members to bring this action in their behalf. This claim of authority is now confirmed in the petition supporting the motion to add the member-fishermen as plaintiffs. To grant the motion merely puts the principal, the real party in interest, in the position of his avowed agent. The addition of these two parties plaintiff can in no wise embarrass the defendant. Nor would their earlier joinder have in any way affected the course of the litigation. To dismiss the present petition and require the new plaintiffs to start over in the District Court would entail needless waste and runs counter to effective judicial administration — the more so since, with the silent concurrence of the defendant, the original plaintiffs were deemed proper parties below. Rule 21 will rarely come into play at this stage of a litigation. We grant the motion in view of the special circumstances before us.

Notes
The appropriation for the office of Tax Commissioner for the biennium beginning April 1, 1949, was $500,000. Alaska Laws, 1949, c. 114. The District Court found that there were approximately 3,200 nonresident fishermen who were 'members of plaintiff union, and the court below added that it might be inferred from the record that an equal number of nonresident fishermen were not members of this union.
After the decision in the Haavik case Congress passed the White Act, 43 Stat. 464, 48 U. S. C. §§ 221-247, comprehensively regulating “the fisheries of the United States in all waters of Alaska” and delegating authority to the Secretary of Commerce (now to the Secretary of Interior) to administer the law. That Act provided . . no exclusive or several right of fishery shall be granted [in reserved fishing areas established by the Secretary in Alaskan waters], nor shall any citizen of the United States be denied the right to take, prepare, cure, or preserve fish or shellfish in any area of the waters of Alaska where fishing is permitted by the Secretary of the Interior.” 43 Stat. 464, as amended, 48 U. S. C. § 222. But see 43 Stat. 464, 467, 48 U. S. C. § 228, which provides that nothing in the Act “shall abrogate or curtail the powers granted the Territorial Legislature of Alaska to impose taxes or licenses . . ."
In 1947, Congress amended the Organic Act of Puerto Rico to' provide: “The rights, privileges, and. immunities of citizens of the United States shall be respected in Puerto Rico to the same extént as though Puerto Rico were a State of the Union and subject to the provisions of paragraph 1 of section 2 of article IV of the Constitution of the United States.” 61 Stat. 772, 48 U. S. C. § 737. In *420 statement explaining the bill, Senator Butler, the manager of the Bill, said, “Congress has not expressly extended the Constitution to Puerto Rico, as it did in the case of Alaska and Hawaii, and the committee considered it advisable to bring Puerto Rico expressly within the operation of the comity clause so as to leave no doubt that there may be no discrimination against citizens of the United States who are not residents of Puerto Rico.’.’ 93 Cong. Rec. 10402. The report of the .Senate Committee on Public Lands expressed dissatisfaction that “Legislation in Puerto Rico has discriminated against nonresident American citizens.” S. Rep. No. 422, 80th Cong., 1st Sess. 4.
