The article presents the issue of a misdemeanour of allowing a minor under the age of seven or another person incapable of recognising or defending him/herself against danger to stay in circumstances dangerous for human health classified in Article 106 MC. In order to provide full characteristics of the discussed type of misdemeanour, a classical pattern based on the traditional division of statutory features of the type of prohibited act has been adopted. The author discusses such issues as statutory penalties for this misdemeanour and concurrence of provisions. The article also draws special attention to issues raising doctrinal controversies, including inter alia: approach to the object of protection, the consequential nature of this misdemeanour type, the scope and sources of the obligation to take care and supervise or the issue of the area in which the misdemeanour under Article 106 MC is concurrent with selected types of misdemeanours and offences.
