The Enabling Act 1933 probably the worse

Probably the worse act to be given the go ahead, in recent history  

The Enabling Act of 1933 (Ermächtigungsgesetz), officially the Act to Remedy the Distress of People and Reich (Gesetz zur Behebung der Not von Volk und Reich), was an Act passed by the Reichstag of Nazi Germany on March 23, 1933, at the suggestion of Chancellor Adolf Hitler.

The Enabling Act granted the German government, headed by the cabinet led by Hitler, the power to pass laws without the consent of the Reichstag or its President. This effectively gave Hitler dictatorial powers, and allowed him to consolidate his control over Germany.

The Enabling Act was passed by a vote of 444 to 94, with the support of all but 94 of the Nazi Party's Reichstag deputies. The Communist Party of Germany (KPD) and the Social Democratic Party of Germany (SPD) boycotted the vote, as they had been prevented from taking their seats in the Reichstag by the Nazis.

The Enabling Act was a turning point in Nazi Germany's history, as it allowed Hitler to establish a totalitarian dictatorship. He used the Act to suspend civil liberties, persecute his opponents, and prepare for war.

The Enabling Act was later declared to be null and void by the Allies after World War II. It is considered to be one of the most important documents in Nazi history, and it symbolizes the beginning of Hitler's rise to power.
