The president of Bavaria’s state parliament canceled a meeting with Hungarian Parliament Speaker László Kövér at the last minute, citing concerns over Hungary’s new amendments to its Constitution, the Heti Válasz website reported.

Barbara Stamm of the Christian Social Union, the Bavarian partner of German Chancellor Angela Merkel’s conservative Christian Democratic Union, had been set to meet with Kövér today on his official visit to her state. Stamm, 68, decided to “delay” the meeting after Hungary passed a series of constitutional amendments on Monday that critics say undermine democratic rule of law.

“The further amendment of the Hungarian Constitution, passed yesterday, has sparked deep concerns and debates in the entire European Union and Germany in relation to Hungarian rule of law,” Stamm’s office said in a statement released Tuesday, according to Heti Válasz.

This marks the first time a CSU politician has publicly criticized Hungary’s government since the Fidesz party swept to power in 2010, the website reported. Other conservatives who have raised similar concerns include European Commission Jose Manuel Barosso and German Chancellor Angela Merkel.

Fidesz has claimed that the vitriol over the constitutional changes has been engineered by the party’s left-wing opponents.

The constitutional amendments include restrictions on political advertisements, prison terms for homeless people and obligations for certain university graduates to work in Hungary for a number of years after they complete their studies. Hungarian President János Áder, a longtime ally of Prime Minister Viktor Orbán, is widely expected to sign the legislation despite a wave of street protests.
