Petri Sarvamaa, a senior member of the EU's parliament, is collecting signatures for a petition to revoke Hungary's voting rights at the European Council, Sarvamaa wrote on Jan. 12.
He initially launched the petition on Jan. 9, which seeks to revoke some of Hungary's membership rights, including voting, due to the country's "erosion of the rule of law" and obstructive behavior in the face of EU consensus building.
Hungary blocked 50 billion euros ($55 billion) in EU funding for Ukraine at a summit in December, which was supported by all other members.
Hungary has maintained a favorable stance toward Russia since the beginning of the full-scale invasion of Ukraine and has repeatedly obstructed sanctions against Russia or blocked other aid for Ukraine within the EU to leverage economic concessions.
Sarvamaa said that he had already collected 120 signatures from members of parliament across the political spectrum and from various countries.
The group then sent a letter to the president of the European Parliament, Roberta Metsola, on Jan. 12.
"We believe that this action is necessary to protect the values of the European Union," the letter read.
Sarvamaa said that the next steps would be to measure the popularity of implementing the measure in the wider parliament, which may be possible as soon as next week.
A decision to revoke Hungary's voting rights would ultimately have to be made by a majority at the European Council.
No EU country has ever had its voting rights suspended before.
