- Legal actions Jakub Skřejpek Key words: Legal actions, manifestation of the will, interpretation Legal actions are generally classified as legal facts, which have effect on the creation, modification and termination of legal actions. Legal actions occur in the sphere of civil law. Legislation of legal actions is included in the current Civil Code, which also provides what conditions must be satisfied to make a legal act valid and vice versa, which is an invalid legal act, either absolutely or relatively. To be valid, a legal act must be a manifestation of the will, which is directed specifically to the creation, modification or termination of a legal relationship and the law must connect such a manifestation of the will with legal consequences. This legal specification is in the Civil Code. In the current draft of the new Civil Code, however, such a definition of legal actions is missing, and are specified only the consequences of legal actions. You can expand, that the validity of any legal action depends on the expression of the will of the acting person, which must be capable of acquiring rights and duties. The validity of the legal action is necessary for the expression of the will of the person to be free, serious, specific and comprehensive enough. It must not be done in distress or under...

The aim of the thesis is to point out difficulties in interpretation of the civil code provisions (the act No. 89/2012 Coll.) regulating mistake as a form of vitiated consent and outline solutions to them on the basis of appropriate interpretation methods. The thesis applies to the legislation of mistake in relation to contracts in general as provided in the civil code, s. 583 - 585 and analyzes the legal consequences made by mistake. The keyword - mistake - is defined in the text in two ways - firstly as discrepancy between the genuine will of the acting person and manifestation of the will, secondly as a defect of the will. The study is primarily focused on the latter case. The text analyzes thoroughly conditions which must be satisfied so that so-called substantial mistake affects legal consequences. These conditions include determining circumstance, mistake caused by the second party and excusability of mistake. A separated chapter is devoted to mistake caused by fraud which is a special type of mistake because of its graveness, and therefore the act provides requirements which are different from those leading to the substantial mistake. The next chapter focuses on mistake caused by the third person. At the end of the work, legal consequences of mistake are illustrated - the right to avoid a...

Lors des travaux de la Commission du droit international relatifs aux actes unilatéraux des États, le rapporteur spécial a nié que le silence puisse être qualifié de manifestation de la volonté étatique. Rien dans la théorie de l’acte juridique ne justifie pourtant cette position. L’étude de la pratique révèle en outre que, selon les cas, le silence étatique peut être qualifié de refus ou d’acquiescement et qu’il joue un rôle fondamental dans la formation, l’interprétation ou la modification des rapports de droit interétatiques. En effet, dans la mesure où, en droit international, il revient aux États d’apprécier le bien-fondé ou la légalité du comportement de leurs pairs, l’objectif de la sécurité juridique impose de retenir la pertinence légale de leur silence. Cet objectif, sous ses diverses facettes, constitue la raison d’être de l’attribution d’un effet légal au silence et permet ainsi une systématisation des hypothèses très variées où il pèse sur les États une « charge de réagir ». Selon la situation face à laquelle il est appréhendé, le silence permet ainsi d’assurer la détermination actuelle ou future des rapports de droit.L’étude des conditions nécessaires à la production de l’effet attribué au silence révèle par ailleurs que le droit positif consacre la possibilité théorique d’y voir un acte juridique. Pour que son silence produise des effets, le droit international exige toujours que l’État ait été libre de réagir et qu’il ait eu connaissance de la situation qui le rendait pertinent. En outre, les régimes de la preuve de la connaissance et de l’existence du silence ne justifient pas nécessairement la dénonciation du caractère honteusement fictif de l’explication volontariste des phénomènes en cause. Il n’y a, en toute hypothèse, aucune fiction juridique à qualifier le silence en tant qu’acte juridique / . During the work of the International Law Commission regarding Unilateral Acts of States, the Special Rapporteur denied that State’s silence could be qualified as a manifestation of its will. Nevertheless,no theoretical reason justifies this position. The study of the practice reveals more over that, as the casemay be, State’s silence can be qualified as refusal or as acquiescence and that it plays a fundamental role in the formation, the interpretation or the modification of legal interstate relations. Indeed, since it is the State’s prerogative to appreciate the legality of the behavior of others States, legal certainty imposes to hold the legal relevance of their silence. Under its diverse facets, this objective constitutes the raison d’être of the effect attributed to silence and thus allows a systematization of the various hypothesis in which it is taken into account. Depending on the situation to which it reacts, silence ensures the current or future determination of legal relations. Furthermore, the study of the conditions necessary for the production of the silence’s effects reveals that positive law consecrates the theoretical possibility of qualifying silence as a legal act. International law requires, in order toattribute an effect to silence, that the silent State was free to react and had knowledge of the situation that made his silence legally relevant. Moreover, the rules governing the proof of the knowledge and of the existence of silence do not necessarily justify the criticism towards the fictive character of the voluntarist explanation of the phenomena. There is, in any event, no legal fiction in qualifying silenceas a legal act.
