opinion: Per Curiam.
  The Interstate Commerce Commission brings an appeal from a three-judge district court, 49 U. S. C. § 305 (g), that reversed an order of the ICC, 62 M. C. C. 413, directing appellee Contract Steel Carriers to cease operations as a common carrier by motor vehicle. 128 F. Supp. 25.
  Appellee holds licenses covering different areas surrounding Chicago, Houston, and St. Louis. As these are substantially in the same form, a single illustration will suffice. It covers contract carriage of
  “Steel articles, and such materials as are used or useful in highway construction projects, except cement, rock, sand, and gravel, over irregular routes, in connection with said carrier’s presently authorized operations,
  “From points and places in the CHICAGO, ILL. COMMERCIAL ZONE, as defined by the Commission in 1 M. C. C. 673, to points and places in Arkansas, Iowa, Kansas, Missouri, Oklahoma, and Texas, and return with no transportation for compensation.” No. MC 96505 SUB 6.
  The facts are fully set out in the reports referred to above. In essence they show that appellee, by active solicitation from 1951 to 1954 in the areas mentioned, had secured 69 contracts to serve shippers. These had been filed with the Commission and there is no charge of any violation of the restrictions of the license or the requirements of individual contracts except that the appellee has held itself out by its actions to be a common carrier.
  The Commission found this holding-out from an advertisement, run without legal advice and since discontinued, offering its transportation service without mentioning whether it was contract or common carriage.
  It was also charged that
  “. . . the great increase in the number of contracts held by it are attributable in large degree to aggressive sales activities and affirmative precontract traffic solicitation, which amounts to a public offer or holding out. In this connection, it is also asserted that defendant maintained an employee in Des Moines, Iowa, whose duties included the active solicitation of traffic. . . . There is evidence that business has been lost by interveners after a representative of defendant called upon receivers of steel in Iowa, leaving a copy of defendant’s schedule of minimum rates and charges, and a copy of a blank contract to be executed by such shippers.” 62 M. C. C. 413, 41A-415.
  It was concluded by the Commission:
  “Although the facts here are meager in some respects, they reveal a pattern of extraordinary expansion in a period of approximately 8 months and an easy turnover of contracts thereafter. We believe that there is ample evidence to show that this expansion was brought about, to some extent at least, by indiscriminate solicitation and advertising, among other things.” Id., at 421.
  In Craig Contract Carrier Application, 31 M. C. C. 705, 712, the ICC stated that the services of a contract carrier must be individual and specialized. A requirement of specialization is supported by respectable legislative history. See, e. g., 79 Cong. Rec. 5651. In this case the ICC found that appellee had not sufficiently specialized its operation. However, we conclude that if specialization is to be read into 49 U. S. C. § 303 (a) (15) by the legislative history, it is satisfied here since appellee hauls only strictly limited types of steel products under individual and continuing contractual agreements with a comparatively small number of shippers throughout a large area.
  We hold also that the fact that appellee has actively solicited business within the bounds of his license does not support a finding that it was “holding itself out to the general public.” A contract carrier is free to aggressively search for new business within the limits of his license. Because the ICC’s order is not supported by evidence in the record and is contrary to the definitions of contract and common-carriers in §303 (14) and (15), we affirm the District Court.
  Affirmed.
  A common carrier is one “which holds itself out to the general public to engage in the transportation by motor vehicle ... of passengers or property.” A contract carrier is any “person which, under individual contracts or agreements, engages in” such transportation. 49 U. S. C. § 303 (a) (14), (15).
  “Provided, however, That no terms, conditions, or limitations shall restrict the right of the carrier to substitute or add contracts within the scope of the permit, or to add to his or its equipment and facilities, within the scope of the permit, as the development of the business and the demands of the public may require." 49 U. S. C. §309 (b).
instruction: What follows is an opinion from the Supreme Court of the United States. Your task is to determine the ideological "direction" of the decision ("liberal", "conservative", or "unspecifiable"). Use "unspecifiable" if the issue does not lend itself to a liberal or conservative description (e.g., a boundary dispute between two states, real property, wills and estates), or because no convention exists as to which is the liberal side and which is the conservative side (e.g., the legislative veto). Specification of the ideological direction comports with conventional usage. In the context of issues pertaining to criminal procedure, civil rights, First Amendment, due process, privacy, and attorneys, consider liberal to be pro-person accused or convicted of crime, or denied a jury trial, pro-civil liberties or civil rights claimant, especially those exercising less protected civil rights (e.g., homosexuality), pro-child or juvenile, pro-indigent pro-Indian, pro-affirmative action, pro-neutrality in establishment clause cases, pro-female in abortion, pro-underdog, anti-slavery, incorporation of foreign territories anti-government in the context of due process, except for takings clause cases where a pro-government, anti-owner vote is considered liberal except in criminal forfeiture cases or those where the taking is pro-business violation of due process by exercising jurisdiction over nonresident, pro-attorney or governmental official in non-liability cases, pro-accountability and/or anti-corruption in campaign spending pro-privacy vis-a-vis the 1st Amendment where the privacy invaded is that of mental incompetents, pro-disclosure in Freedom of Information Act issues except for employment and student records. In the context of issues pertaining to unions and economic activity, consider liberal to be pro-union except in union antitrust where liberal = pro-competition, pro-government, anti-business anti-employer, pro-competition, pro-injured person, pro-indigent, pro-small business vis-a-vis large business pro-state/anti-business in state tax cases, pro-debtor, pro-bankrupt, pro-Indian, pro-environmental protection, pro-economic underdog pro-consumer, pro-accountability in governmental corruption, pro-original grantee, purchaser, or occupant in state and territorial land claims anti-union member or employee vis-a-vis union, anti-union in union antitrust, anti-union in union or closed shop, pro-trial in arbitration. In the context of issues pertaining to judicial power, consider liberal to be pro-exercise of judicial power, pro-judicial "activism", pro-judicial review of administrative action. In the context of issues pertaining to federalism, consider liberal to be pro-federal power, pro-executive power in executive/congressional disputes, anti-state. In the context of issues pertaining to federal taxation, consider liberal to be pro-United States and conservative pro-taxpayer. In miscellaneous, consider conservative the incorporation of foreign territories and executive authority vis-a-vis congress or the states or judcial authority vis-a-vis state or federal legislative authority, and consider liberal legislative veto. In interstate relations and private law issues, consider unspecifiable in all cases.
