5. What is the practice of invalidation of transactions in Germany, if there is such information is there any statistics? What is the difference between it and the practice of Kazakhstan?
When it comes to the recognition of invalid transactions in Germany, it must be noted that the approaches of German law differ from the law of Kazakhstan. The first feature is that voidable transactions become invalid from the moment of reception of the will of contestation of the transaction by other party to the transaction. That is, in case the contestation is not recognized by the other party, the court simply considers presence of three conditions of a contestation: the basis of a contestation (for example, conclusion of the transaction under the influence of delusion); presence of the will of a contestation; and, thirdly, whether the transaction is contested within the term provided by the law. If all three conditions are satisfied, the transaction will be considered invalid from the moment of its contestation. That is, the court merely states the fact, but does not change the legal situation with its decision.
In the case of null transactions, however, the court must apply the consequences of nullity on its own. Obviously, nullity must be provided directly by the legislation, as the basic principle is freedom of contract, that is, all contracts are valid if their invalidity is not provided by the legislation. If the nullity is stipulated as a legal consequence in a rule of law, no questions arise. There are, however, broad norms that need to be interpreted. These are the nullity of a transaction that contradicts the law and the nullity of a transaction that does not meet the requirements of morality. In these cases, the law enforcer must interpret the purpose of the law and find out whether the legislator intended to achieve exactly the nullity of the transaction. In many cases, it turns out that the purpose of the prohibiting norm is not the invalidity of the transaction. Sometimes it is enough only administrative responsibility, if it is stipulated by law, and sometimes only partial invalidity of the transaction. That is, one of the parties to the transaction, whose rights are protected by the norm of law, retains its rights from the transaction. This approach is shaped by judicial practice. In this regard, it is very interesting to examine Art. 3.3.1 of the UNIDROIT Principles of Commercial Contracts, which, in the case of unlawful transactions, do not provide as a consequence of their invalidity, but provide the parties only "proportionate instruments of legal protection". It is important to note that this approach has developed in most jurisdictions independently and has been adopted by the Principles relatively recently.
Thus, the German law treats transactions more carefully, as they are the basis of civil turnover and it is important not to get the opposite effect from the invalidity of the transaction, when the negative consequences will occur for the party in good faith. Soviet law treated private transactions more severely. Any violation of law led to the nullity of the transaction and even to the confiscation of property in favor of the state. The transaction itself had no high value for the legal system. The state economy was regulated by other institutions, and the protection of the interests of citizens was heavily shifted to the field of public law.
Although many countries have abandoned the approaches described in socialist law, certain elements remain. For example, the law of Kazakhstan provides, as a rule, for the contestability of unlawful transactions. That is, the majority of such transactions are not void as in Soviet law. However, in case of contestation of such a transaction, the courts recognize the transactions as invalid. That is, there is no flexibility of approach inherent in German law, as well as provided by the Principles. In this connection it is important to note that many legal systems have moved away from the automatic application of invalidity, contrary to the explicit direction of the law. For example, Austrian courts apply a flexible approach even though the Austrian Civil Code provides for the nullity of unlawful transactions.
