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.  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. Spre exemplu, daca intre partile contractante se naste un diferend, o intelegere care nu este concretizata intr-un contract scris cu greu poate fi probata si nu intotdeauna in totalitate. Prin urmare, desi legea recunoaste ca fiind valabile aceste intelegeri de tipul “gentlemen`s agreement,” partile nu beneficiaza de protectie legala suficienta. A gentlemen`s agreement is easy to conclude and costs nothing. If you enter into an agreement that contains no significant value, a gentlemen`s agreement is preferable, as there is no reason to invest time and money in contract formation. Gentlemen`s agreements are often used in situations where it is considered shady or cowardly to hide behind contractual clauses. In the automotive industry, Japanese manufacturers have agreed that no standard vehicle would have more than 276 hp (206 kW; 280 CH); The agreement ended in 2005.  German manufacturers limit the maximum speed of high-performance sedans (berlines) and breaks to 250 km/h.   When the Suzuki Hayabusa motorcycle exceeded 310 km/h in 1999, fears of a European ban or regulatory intervention led Japanese and European manufacturers to limit to 300 km/h at the end of 1999 See list of the fastest series bikes. A gentleman`s agreement, which is rather a point of honour and etiquette, relies on the indulgence of two or more parties for the performance of pronounced or unspoken undertakings. Unlike a binding contract or a legal agreement, there is no legal remedy for violation of a gentlemen`s agreement.
