How did Otto von Bismarck collect taxes without parliamentary approval between 1863 and 1866?

Between 1863 and 1866, Otto von Bismarck collected taxes without parliamentary approval by utilizing an ingenious constitutional theory he devised to resolve the deadlock between the crown and the legislature.12

When the Prussian Chamber of Deputies refused to approve the budget for military reforms, Bismarck argued that the constitution contained a "gap" because it did not specify a procedure for when the government and the legislature failed to reach an agreement. He maintained that, in such an event, it was the king's duty to ensure the continued functioning of the state, including the payment of civil servants. Consequently, the government proceeded to collect and spend taxes based on the previous budget without parliamentary sanction.123

This policy of confrontation allowed Bismarck to implement his military reforms despite the lack of legislative authorization. The constitutional crisis was ultimately resolved following Prussia's victory in the Seven Weeks’ War in 1866, after which Bismarck requested and received an act of indemnity from the parliament to retroactively legalize the expenditure.2341
