If a declaration resulting from pre-contract negotiations has become a contractual clause, the usual principles apply to the decision to terminate the contract. The court will ask whether the agent promised in the contract that the statement in question is accurate. If so, was that promise broken to commit a violation of the common law or to trigger contractual termination clauses as described above? If this is the case, the innocent party may terminate the contract for violation. Puffery: Advertisers often use the stamp to promote their products. The advertising slogan “Red Bull Gives You Wings” was a real statement or a ballpoint pen? In a class action filed on January 16, 2013 in the U.S. District Court of the Southern District of New York by Benjamin Careathers, Mr. Careathers stated that he had been drinking Red Bull since 2002. His complaint argued that Red Bull should mislead consumers about the superiority of its products, starting with the slogan “Red Bull gives you wings” and its claims to increase power, concentration and reaction speed. Red Bull eventually joined the complaint and sent a statement to BevNET.com, Inc., a beverage-focused media company, saying, “Red Bull settled the complaint to avoid the costs and distractions of litigation. Red Bull maintains, however, that its marketing and labelling have always been truthful and correct, and denies any fault or responsibility. Each contracting party must be a “competent person” with the force of law.
The parties may be individuals (“individuals”) or legal entities (“companies”). An agreement is reached if an “offer” is adopted. The parties must intend to be legally connected; and to be valid, the agreement must have both a correct “form” and a legitimate purpose. In England (and in jurisdictions using the principles of the English treaty), the parties must also exchange “counterparties” to create a “reciprocity of engagement,” as in Simpkins/Country.  Not all agreements are necessarily contractual, as the parties are generally considered to be legally bound. A “gentlemen`s agreement” should not be legally applicable and “compulsory only in honour.”    Contract law is based on the term indenkisch pacta sunt servanda (“agreements must be respected”).  The Common Law of Contract was born out of the now-disbanded letter of the assumption, which was originally an unlawful act based on trust.  Contract law is a matter of common law of duties, as well as misappropriation and undue restitution.  It is not always easy to decide whether a contract term is a condition, a guarantee or an interim period.
