The same day the
Law was adopted (30 July), the public prosecutor for Belgrade indicted all communist MPs and asked the Parliament to rescind their
parliamentary immunity, so that they can be tried according to the newly adopted
Law in connection to the Stejić's failed assassination of crown prince. This proposal was adopted with the same majority as the
Law itself. Nine communist MPs were arrested the same day, while leaving the parliament building. Two more were arrested in September, and two more in October. Others were
internally exiled to the place of birth. This was a major blow to both the CPY and its youth wing (
SKOJ), which both almost disintegrated and needed decades to recover. The trial of Stejić for the attempted assassination of crown prince started on 25 January 1922. Stejić was sentenced to death and others to prison sentences. Former MPs were sentenced to 2 years each, among them
Filip Filipović,
Đuro Salaj,
Vladimir Ćopić, and
Nikola Kovačević. In the ensuing years, many other legal processes were held against communists accused for violating the
Law on the Protection of the State. Among those was the
Bombers' trial against
Josip Broz Tito. Other prominent communists who were imprisoned for violating the
Law during the 1920s were
Sima Marković (former MP),
Đuro Cvijić,
Ivan Milutinović,
Moša Pijade,
Đuro Đaković,
Rodoljub Čolaković, and
Otokar Keršovani. In the summer of 1924, HRSS joined the
Peasant International, an organization based in Moscow with close ties to the
Communist International. Because of this, in December 1924, the government adopted a decree that applied the
Law on the Protection of the State on the HRSS. HRSS was banned as a "communist organization". HRSS president
Stjepan Radić was arrested on 5 January. They were all released from prison in July 1925, after HRSS decided to distance itself from the communists, accept the monarchist constitution and rename itself to the Croatian Peasant Party (HSS). Immediately after their release, HSS members joined the Government == Later amendments ==
