Gentlemen`s agreements were a widespread discriminatory tactic, which would have been more common than restrictive alliances to maintain the homogeneity of upper-class neighborhoods and suburbs in the United States.  The nature of these agreements made it extremely difficult to prove or follow them, and they were long after the U.S. Supreme Court decisions in Shelley/. Kraemer and Barrows v. Jackson.  A source indicates that the gentlemen`s agreements are “probably still in place” but that their use has declined sharply.  Until Jackie Robinson was hired by the Brooklyn Dodgers in 1946, a gentlemen`s agreement ensured that African-American players were excluded from organized baseball.  “In English contract law, there is a generally accepted rule that informal agreements between parties can be binding where there is an “intention to create legal relations.” Gentlemen`s agreements can also be found in trade agreements and international relations. One example is the 1907 Gentlemen`s Agreement, in which the United States and the Japanese Empire addressed immigration from Japan and the mistreatment of Japanese immigrants to the United States. The agreement, which was never ratified by Congress, saw Japan stop issuing passports to people who wanted to immigrate to America to work. The United States, on the other hand, would no longer allow discrimination and segregation of Japanese citizens residing in America. A gentleman`s agreement is an informal and non-binding agreement in which the parties trust each other to keep their promises.
We can also use the plural and say “gentlemen`s agreement”. It is generally not a document, i.e. there are no signatures, papers or fonts. When one party breaks the agreement, the others generally do not have recourse to the courts. Simply put, a gentleman`s agreement does not have the force of law in most places. Japan was prepared to limit immigration to the United States, but was seriously injured by San Francisco`s discriminatory law, which specifically targeted its people. President Roosevelt, who wanted to maintain good relations with Japan as a pole opposed to Russian expansion in the Far East, intervened. While the U.S. ambassador reassured the Japanese government, Roosevelt summoned the mayor and the San Francisco school board to the White House in February 1907 and convinced him to end segregation and promised that the federal government itself would address the issue of immigration.
On February 24, the gentlemen`s agreement was reached with Japan in the form of a Japanese memo, in which it was agreed to deny passports to workers wishing to enter the United States and to recognize the right of the United States to exclude Japanese immigrants with passports initially issued to other countries. March 13, 1907 followed the formal withdrawal of the San Francisco School Board`s decision. A final Japanese note, dated February 18, 1908, made the gentlemen`s agreement fully effective. The agreement was replaced by the Immigration Exclusion Act of 1924. A gentleman`s agreement, defined at the beginning of the 20th century as “an agreement between gentlemen who looks at price control,” has been described by one source as the most lax form of a “pool.”  Such agreements have been declared in all industrial sectors and are numerous in the steel and steel industry.  Gentlemen`s agreements, because they are informal and often not written, do not enjoy the same legal and regulatory protection as a formal contract and are therefore more difficult to implement. A report by the U.S. House of Representatives detailing its United States Steel Corporation investigation stated that in the 1890s there were two general types of associations or bulk consolidations between steel and ferrous interests in which different groups owned ownership, as well as a high degree of independence: the “pool” and the “Gentleman`s Agreement.”  The latter type lacked a formal organisation to regulate production or prices or forfeiture rules in the event of infringement.
