Abstract: The subject of this research is the legal norms, doctrinal provisions and case law on the conditions of civil liability. The relevance of this topic is determined by the tendency to expand the list of cases of strict liability detected in comparison the current and Soviet legislation. However, the principle observed by the legislator in transferring cases from the "regime of fault liability" to the "regime of strict liability" is still a puzzle. For the purpose of systematicity of legislation and reasonable claim of strict liability, such principle should be captured in legislation. The goal of this research lies in determination of the condition of civil liability without fault. Using the method of legal induction, the author formulates the conclusion on the condition of strict liability based on the analysis of separate court decisions and legal norms dedicated to various cases of strict liability. A number of cases of civil liability without fault specified in the law are substantiated by a different (instead of fault) condition of liability, namely the implementation of professional activity that entailed civil violation. If the case of liability without fault specified in the law does not contain any other condition of liability alternative to fault, the corresponding rule should be excluded from the law due to groundlessness (for example, the rule on strict liability for obligations of the trustee in relation to individuals who are not the subjects of professional activity in this sphere; the rule on compensation for moral damages irrespective of guilt for distribution of discrediting information by a person who is not a professional distributor of mass media products). The author offers to legislate the principle of civil strict liability.

Abstract: The subject of this research is the legal norms on the status of underage parents. Custody of a child of underage parents is regulated by special rules in Russia and abroad. The Russian legal model of child custody of underage parents is yet to be established. Unlike the countries of Germanic legal group (Germany, Switzerland, and Austria), the legislation of which features detailed description of the legal status of underage parents, the Russian legislation requires further improvement in this regard. Application of the method of comparative jurisprudence allowed determining the common and distinctive characteristics in the legal status of underage parents in German, Austrian, Swiss, and Russian legislation. The common feature for all aforementioned legislations consists in automatic removal of custody of a child of an underage parent when such parent attains the age of majority. In the author’s opinion, the best model of child custody (with regards to a child of underage parents who have reached the age of 16) is German model: an underage parent with partial civil capacity and a guardian both have rights to participate in parenting of a child, while guardian is the only legal representative of a child of an underage parent (in case if a child has no parents of the age of majority).
