Whether the two parties have reached agreement on the terms or whether a valid offer has been made is an issue which is determined by the applicable law. In certain jurisdictions, courts use criteria known as 'the objective test' which was explained in the leading English case of "Smith v. Hughes". In Smith v. Hughes, the court emphasised that the important thing in determining whether there has been a valid offer is not the party's own (subjective) intentions, but how a reasonable person would view the situation. The objective test is largely superseded in the UK since the introduction of the Brussels Regime in combination with the Rome I Regulation.
