The Magistrate of Vienna imposed a fine on the appeal applicant, as a manager registered to trade on behalf of a limited company, for allegedly committing two offences under the PrAG. In the first place (fact one), the company had failed to meet its statutory obligation to display prices clearly on its business premises because the bureau de change it operated only displayed the fees for currency exchange on two paper signs – each measuring circa 12 x 10 cm – on the inside of the glass in the corner next to the counter. In the second place (fact 2), with respect to another business operated by the company, goods (two T-shirts, a towel, pens and lighters) were on display and offered for sale in a shop window, but the price was not labelled either in the window display or in the shop itself. For the two offences, the magistrate imposed a fine of 4,000 Austrian Schillings on the defendant (with a 67-hour custodial sentence for non-payment).
In his appeal, the manager of the company complained with regard to fact 1 that the interdiction “nullum crimen sine lege“ had been infringed. The duty to label prices, which he had allegedly infringed and was being fined for under the PrAG, had been laid down in §§ 2 and 3 PrAG. Unlike § 2, which casts the duty to label prices in general terms, the duty to label prices for services under § 3 was linked to a decree by the Minister for Economic Affairs. This decree (BGBl 1992/813) made no mention of bureaux de change, hence the defendant had no obligation to label prices for services either he or the company provided. With regard to fact 2, the appeal applicant argued in essence that he had indeed labelled the prices for the goods in his shop.
