Ruthenia and Karnia maintained separate parliaments each with its own prime minister under the monarch after the Karno-Ruthenian Compromise of 2016. After the Imperial Constitution of 2017, the parliaments were unified into one, the Imperial Diet, a bicameral parliament with representatives of all the regions of the Empire. In accordance with article 80, Chapter V of the Constitution, the Imperial Diet is the political body with the highest authority in government, responsible for administering legislative power, and is divided into an upper chamber, the House of Peers, and a lower chamber, the House of Representatives. The competences of the Imperial Diet are: authorize the declaration of war and the celebration of peace, override State of Exception declaration, authorize the ratification of international treaties, authorize the resignation of the Emperor and recognize the Crown Prince, authorize the marriage of the Emperor and the Crown Prince, supervise the activities of the Cabinet, give effect to motion of no confidence, elect by relative majority the Imperial Chancellor and enact constitutional amendments.
The government comprises ministers for joint responsibilities (culture, finances, foreign affairs, immigration, imperial and royal household, information, interior and of defense). On June 2016, two ministries were created: the Ministry of Strategic Affairs, responsible for the development of new approaches from the Imperial and Royal Government to its citizens and foreigners and the Ministry of Antarctic Affairs, to protect, defend and clarify the situation of the Antarctic continent and specially the current status of the Grand Duchy of Gaussland. The last ministry created was of the justice, on 09 December 2016, related to the Imperial Supreme Court. This structure was maintained after the promulgation of the new constitution.
The offices of Minister-President of Ruthenia and the Prime Minister of Karnia were created after the Comrpomise, but replaced by the office of Imperial Chancellor. The Imperial Chancellor of Karnia-Ruthenia, is the head of government of the Karno-Ruthenian Empire and leader of the Cabinet, appointing and dismissing its members. The Imperial Chancellor do not have a fixed mandate, leaving the office by resignation or motion of no confidence of the Imperial Diet. Among its competences, are exercise the highest authority in matters concerning the Government, head the Cabinet, appoint and dismiss the members of the Cabinet, upon the consent of the Emperor, advise and be advised by the Emperor, create and regulate imperial agencies, propose bills to the Imperial Diet, monthly take part in the Imperial Diet, in Ordinary Session, to answer the Questions to the Imperial Chancellor.
At the beginning of Ruthenian history, which is the origin of the Empire itself and the state with the most profound legal tradition, did not have a single legal system, considering the use of common-law principles. However, when the General Assembly of the Kingdom was established, the development of more specific laws such as the Civil Code, eventually forced the creation of a different legal system of the intended previously. Therefore, extensive legislation was created between the years 2014 and 2016 until the signing of the Karno-Ruthenian Compromise of 2016.
Since the states of the Empire were formed in a large majority of new micronations, most of the legislation would be coming from the proper legislative process of the Empire, which largely was the Ruthenian legislation adapted to this new situation. In 2016, after the Foundation of the Empire, the common Criminal Code and a Civil Code, adapted of Ruthenian versions of 2015 was introduced after the consolidation of the Constitution over all other constitutions of the states that composed the Empire.
The legal culture of the Empire has always been very rich, but has become much improved over time, especially after the completion of the work of the Constitutional Commission and the promulgation of the new constitution.
The Karno-Ruthenian Compromise of 2016 created the semi-independent states of Ruthenia and Karnia linked by personal union under a common monarch, establishing a constitutional monarchy with a system of corporative federalism, a system of federalism not based on the common federalist idea of relative land area or nearest spheres of influence for governance, but on fiduciary jurisdiction to corporate personhood, where groups who are considered incorporated members of their own prerogative structure by willed agreement can delegate their individual effective legislature within the overall government. This system is similar to that used by the Austro-Hungarian Empire, a version of corporative federalism that gave its wide demographic of different ethnicities each their own individual rights within their own assemblies instead of by relation to the territory of the Empire.
The Imperial Constitution of 2017, the third in force throughout Karno-Ruthenian history, ensured numerous new rights to the population, like a more representative and less confused democracy through a unified parliament, the Imperial Diet. Making the state leaner and more efficient was one of the commission’s biggest challenges, which made the Empire a unitary and cohesive state. This made the Empire more distant from the Austro-Hungarian model chosen at first, which made the state structure more like a modern state.
The foreign relations of the Empire are implemented by the Ministry of Foreign Affairs. The Emperor-King and the prime ministers of each part of the Empire play a role in setting policy, and the Minister of Foreign Affairs have a voice and are the one who develop this policy. Since its founding, the Kingdom of Ruthenia and after the Karno-Ruthenian Compromise of 2016, the Karno-Ruthenian Empire and its government pays special attention to foreign affairs. One of the first ministries of government was precisely the Ministry of Foreign Affairs, which was founded on the same day that the kingdom, on 19 November 2014. Diplomatic relations are conducted by the Minister of Foreign Affairs, but the leadership of Foreign Affairs is in practice, led by His Imperial and Royal Majesty, the Emperor-King. Karnia-Ruthenia monthly studies and develops diplomatic relations with several micronations around the world, maintaining cordial relations with everyone and accounting for only four international incidents, only two of whom suffered from more serious action by the government.
