The Constitutional Court of the Republic of Bulgaria has accepted the evidence regarding the case of Kiril Petkov's citizenship. The court is expected to give a ruling in that case by the November 14 elections. The Constitutional Court must establish when the Canadian authorities ruled that Bulgaria’s former caretaker Minister of Economy Kiril Petkov was no longer a Canadian citizen. 

Meanwhile, the Constitutional Court refused to hear Kiril Petkov on the grounds that only an incumbent MP, President or Vice President could be constituted as an interested party. Kiril Petkov could be subject to criminal liability, if he had Canadian citizenship and nevertheless declared that he met the requirements to become a minister, Associate Professor Natalia Kiselova said in an interview for the Bulgarian National Radio.
