Business contracts are formed through negotiations, where the parties agree on some terms, disagree on others and keep yet others undecided. Over a period of time, they see themselves as having moved from being negotiating parties to contracting parties, settling on most of the terms. The law, however, states that a contract is formed when a person makes an offer and the other accepts it. The principle arose from the rudimentary trade practices in the past. The principles coming from the prior centuries and the modern business practices may not be in consonance. The Gibson v. Manchester City Council Case, a judgement of the House of Lords of the United Kingdom, reviewed attempts to modernize the law.
