Why did Bismarck govern Prussia without an approved budget from 1863 to 1866?

Otto von Bismarck governed Prussia without an approved budget from 1863 to 1866 due to a constitutional deadlock between King William I and the liberal-dominated Chamber of Deputies.12

The conflict arose from the King’s desire to implement military reforms, specifically increasing the size of the army and the duration of service. When the liberal majority in the Chamber of Deputies refused to approve the necessary revenue for these reforms, the government faced a crisis.132

To bypass this impasse, Bismarck devised the theory that there was a "gap" in the Prussian constitution. He argued that because the legislature and the crown could not reach an agreement, the government was duty-bound to continue functioning in the interim to pay civil servants and maintain state operations. Consequently, Bismarck collected and spent taxes based on the previous year's budget without parliamentary sanction. This allowed him to implement the military reforms despite the lack of legislative approval. The crisis concluded in 1866 following Prussia's victory in the Seven Weeks’ War, after which Bismarck requested and received an Act of Indemnity from the parliament for his unconstitutional actions.124
