A refresher on the Clone Wars plan
The Emperor, who brought the Clone Wars to an end, uncovers the fact that the Jedi were planning the battle and that they were controlling the war situation behind the scenes by manipulating both allies and enemies.
Most of the senators accept the Emperor's explanation and understand the scenario that the Jedi intended to make Palpatine a dictator and take over.
For this reason, it is convenient to argue that emergency powers were forcibly granted.
In fact, the establishment of emergency powers was essentially a forced vote.
The Senate, which had struggled to such an extent with the creation of a republican army and the possession of a regular army, suddenly approved the establishment of emergency powers in the face of security threats.
This weakness of democracy seemed to have come as a surprise to Palpatine, and he was hesitant about borrowing this much authority. He even made it clear that he would be happy to give it back when the crisis was over. (No one expected Palpatine to become a dictator)
Even before the Emergency Powers were established, Palpatine was assisted by Yoda's advice. Yoda's experienced advice was invaluable in dealing with the Senate's most complex challenges.
For many years, Yoda has been concerned about the senate's corruption and depravity, and has warned that he is unable to prepare for emergencies.
How should the Senate act in times of emergency? Yoda suggests that there is an option called emergency powers.
He temporarily borrows the power held by the Senate as prerogative, bypassing parliamentary resolutions and creating a swift and powerful top-down system. He can save slow and dull resolutions and parliamentary approvals.
When Lord Sidious hears of this method, he is very pleased.
In this case, you can fool the Senate by stating that you are only borrowing it temporarily and that you will be happy to return it later. If the crisis situation is prolonged after it is established, power will legally be concentrated in Palpatine's hands all at once.
Yoda proposed emergency powers, but he never thought they would actually pass. In other words, he did not imagine that the republic would face a crisis situation.
He also praises Palpatine's promise to Congress to return emergency powers. I felt relieved because it was a temporary exercise. He promises to quickly end the Clone Wars.
However, the end of the war was delayed considerably, and the day when prerogative powers were returned never came. The Senate will be eviscerated and an abnormal dictatorship will be established.
Yoda regretted his twisted use of emergency powers. He probably told everyone he shouldn't have told Palpatine about emergency powers. (He told the Sith Lord directly)
Yoda could not imagine a situation where emergency powers would not be returned. He was made to break his promise to the emperor.
(Mace and his friends also believed in the return of prerogatives, right? Anakin had doubts.)
If Yoda or the Council insisted on imposing emergency powers in the Senate, it would confirm the scenario that the Jedi orchestrated the war.
