Verfassung von Tarnowo
According to Article 17 of the Tarnovo Constitution, treaties had to be ratified by the National Assembly. In the case of the Tripartite Pact, the government sought to have the treaty ratified without debate or discussion. Seventeen opposition deputies submitted an interpellation and one, Ivan Petrov, asked why the National Assembly had not been consulted in advance and whether the pact involved Bulgaria in war. They were ignored. The pact was ratified by a vote of 140 to 20.
