Article 4:109 of the Principles of European Contract Law stipulates prohibits gaining the excessive benefit or unfair advantage for a party to take advantage of other party.(1) A party may avoid a contract if, at the time of the conclusion of the contract:(a) it was dependent on or had a relationship of trust with the other party, was in economic distress or had urgent needs, was improvident, ignorant, inexperienced or lacking in bargaining skill, and (b) the other party knew or ought to have known of this and, given the circumstances and purpose of the contract, took advantage of the first party’s situation in a way which was grossly unfair or took an excessive benefit.
Situations
This article applies in three situations; a) a party was dependent on or had a relationship of trust with the other party: b) a party was in economic distress or had urgent needs; c) a party was improvident, ignorant, inexperienced or lacking a bargaining skill. This article regards it as unfair that a party took advantage of the other in above situations or circumstances.In Japan, the each abusive practice is divided in different rules or principles.
Against fiducially duty
Firstly, when a party was dependent on or had a relationship of trust with the other party, the abusive practice of the other party that take advantage of the first party’s credulity is regard as the breach of fiducially duty or duty of loyalty. The notion is not common, but tends to be adapted in lower court rulings in investment transaction cases. The remedy of the offence is damage relief by tort or lacking performance. However, the rationale of the duty seems to be ambiguous or confused amongst court rulings. Most court decisions seem to consider that the nature of breach of the duty is against good faith.
Against public order and morals
Secondly, when a party is in economic distress or had urgent needs and the other party takes advantage of the first party’s situation in a way which was grossly unfair or took an excessive benefit, the other party’s practice is offensive to public order and morals (civil law, sec. 90). The notion of public order and morals is similar to the concept of “the unconscionable conduct”. The contract against the principle is void.
Undue influence or offence of suitability obligations
Third situation is that a party is in improvident, ignorant, inexperienced or lacking a bargaining skill. If the other party takes advantage of the first party’s situation, the practice of other party is regarded undue influence. It is usually to be considered as bread of good faith. However, if the injuries party is seriously damaged by the offence, it might be against public order and morals, taking account of the degree of wrongful intention in the other party. The breach of suitability obligations takes place in the same situation of the first party. Being subject to the suitability rule, when the other party recommends a particular transaction to the first party, the other parry must have a reasonable basis for believing that the transaction is suitable for consumer’s status. In making this assessment, the other party must consider the first party’s knowledge and recognition, same sort of trading experience, objectives and need of transaction, financial status and so on. As a result of assessment, if the other party knew or ought to have known of the first party’s situation where he is improvident, ignorant, inexperienced or lacking in bargaining skill, the other party must not progress the solicitation or form the contract with the first party as a requirement of suitability duty. In this occasion, to fulfill the offence of suitability obligations, the other party need not take advantage of the first party’s situation in a way which is grossly unfair or took an excessive benefit.
Remedy
The remedy of offence is varied depending of the state of the first party. When the lack of the suitability in the injured party is material, the contract that is formed under the situation should be capable of being void against public order and morals. But there can not be found such court ruling so far. Most ruling only indicates damage compensation against this rule.
