174 (1921). The purpose of the compact was to coordinate the growth of transportation and terminal facilities in the port area. Transportation facilities were broadly defined and included railroad facilities “for use for the transportation or carriage of persons or property.” N.Y. Unconsol.Laws § 6423 (McKinney 1961). The Authority was ordered to devise plans for the development of the port district from time to time, but few specific duties were imposed. Future projects were contingent on the development by the two states of a comprehensive plan for the port. Art. XI, VI, X, 1921 Compact.
The comprehensive plan was passed in 1922. Laws of New York, 1922, Ch. 43; Laws of New Jersey, 1922, Ch. 9; 42 Stat. 822 (1922). Most of the provisions were directed at alleviation of freight problems, the most pressing difficulty in the port area at that time. Although the early emphasis was on freight transportation, the Authority was empowered to construct tunnels and bridges, which would also benefit passengers, and to proceed with further projects when directed by the states to do so.1
In 1962 the two legislatures passed the statutes under attack in this litigation. Laws of New York, 1962, Ch. 209; Laws of New Jersey, 1962, Ch. 8. They authorized and ordered the Authority to acquire the Hudson Tubes railroad system and to construct a World Trade Center in lower Manhattan. In directing the Authority to enter the field of passenger railroad operations (with the Hudson Tubes), of which none in the port area is self-supporting, the states provided that the Authority “not proceed with the effectuation of any railroad or railroad facility in addition to the Hudson tubes and the Hudson tubes extensions until hereafter expressly authorized by the two states.” N.Y.Uncon-sol.Laws § 6603 (McKinney Supp. 1971).
In addition, the states and Authority bondholders covenanted that “neither the states nor the Port Authority nor any subsidiary corporation incorporated for any of the purposes of this act will apply any of the rentals, tolls, fares, fees, charges, revenues, or reserves, which have been or shall be pledged in whole or in part as security for such bonds, for any railroad purposes whatsoever other than permitted purposes hereinafter set forth.” Permitted purposes do not include passenger railroads that are not self-supporting or do not operate within strict deficit limits outlined in section 6606.2
The district court dealt only with the issue of the presence of a federal question to confer jurisdiction on the court. We find it unnecessary to reach that point, however, for plaintiffs did not show the requisite $10,000 in controversy as required for federal jurisdiction under 28 U.S.C. § 1331. The burden of proving jurisdictional prerequisites lies on the party who seeks the exercise of jurisdiction in his favor. “[I]nquiry is primarily directed to the one who claims that the power of the court should be exerted in his behalf . . . [H]e must carry throughout the litigation the burden of showing that he is properly in court.” McNutt v. General Motors Acceptance Corp., 298 U.S. 178, 189, 56 S.Ct. 780, 785, 80 L.Ed. 1135

In 1959 the states passed concurrent legislation permitting the Authority to purchase and own railroad cars for the purpose of leasing them to commuter railroads within the electing state. The money used by the Authority to purchase the cars had to be guaranteed by the state before the Authority could proceed. Laws of New York, 1959, Ch. 638; Laws of New Jersey, 1959, Ch. 25.

Effective June, 1971, the states directed the Port Authority to provide rail access to Kennedy and Newark Airports from Newark and New York. Laws of New York, 1971, Chs. 474, 475; Laws of New Jersey, 1971, Ch. 245. Studies are presently being done by financial and engineering consultants on the project. The question of any incompatibility of the rail links legislation with the 1962 bondholders covenant with the states is not raised in this action.
