The Ministry is responsible for the setting of rules concerning the prices for both letters not exceeding 50 gramms as well as official correspondence. This does not mean, however, that there is a monopoly on letters not exceeding 50 gramms since this category is not mentioned in the relevant provisions dealing with the exclusive competence of the Hungarian Postal Office (Magyar Postal), which is stipulated under ss. 24-32 of Act CLIX of 2012. Only official correspondence remains subject to monopoly under s. 30(1) of Act CLIX (see also, above CR.1.12.1 and 2)
