On 28 June 1911, deputies of the party submitted a document called "Memorandum of the SNS" to the Hungarian government. In this document the SNS demanded the practical implementation of the so-called Nationalities Law from 1868 (the law declared all citizens of the Kingdom of Hungary members of a single Hungarian Hungarian "Magyar" nation and Hungarian the only state language; the minor educational, administration and church rights for non-Hungarian nationalities stipulated in the law were never implemented), the permission to use the Slovak language in some types of schools at least and the returning of the property of the dissolved Matica slovenská. The Hungarian government rejected all of these demands. After this decision, the SNS started to co-operate more with representatives of Czech politics.
