The Constitution of the Kingdom of Prussia is the Consistution of the Kingdom of Prussia (Holy Germania), being adopted in 1850 and amended many times to the present day. It is similar to the Consistution of Holy Germanian Empire.
The Consistution puts the King of Prussia (Holy Germania) at the head of the government system. According to it, the Prussian king appoints and dismisses the prime minister (the Chancellor of the Empire as well) and government members, repersents the Kingdom and maintains Prussian domestic affairs, pardons and shortens terms of criminals, appoints members of court and create judical branches, create royal symbols or change them, award honors and awards to persons, assembles his Council and dismisses them, calls and dismisses the parilament, commands the Prussian armed militia and legislature, and offically and cermonially leds the kingdom with full power as head of state and head of operations. The king has full immunity and can change the consistution of Prussia at his will. All Prussian laws and resolutions are passed in his name and proposed in his name. The king signs and seals these laws for them to become offical, or may refuse to do so. The king also can issue Royal Proclamations, Royal Laws, Royal Authorizations, Royal Reports, Royal Orders, and such at his own discretion and may repeal or change them at any time.
Next the Consistution puts the Prime Minister as the King's chief minister and leading advisor, appointed and dismissed by him at his will. The Prime Minister executes the King's orders, leds the government, maintains politcal affairs, and chairs his Cabinet.
The Consistution also formulates a parilament, the Prussian Parilament. The upper house is the House of Commonalites, elected by the top ninety nine percent of voters basing on tax-paying ablity. The Commonalites has little powers but acts as a legislative screening and supervision council. However this House may block bills and can propose tax laws and economic budgets. The lower house is the House of Delegates, elected by the top eighty nine percent of voters through their electoral repersenatives who meet and choose members at the voter's majority vote. This House has almost unlimited legislative power and can overule the upper house on economic and military issues. This House also can propose bills.
The Consistution also guidelines the Prussian military, land affairs, communications, economic affairs, maritime affairs, and relations with other Imperial states.
