Which action can Congress not perform according to the Constitution

Congress cannot pass a bill of attainder, ex post facto laws, or suspend the writ of habeas corpus.

Explanation

The three actions that Congress cannot perform according to the Constitution are important to protect the rights of citizens.

A bill of attainder ensures that individuals cannot be declared guilty without a trial. This is important to protect the right to due process and ensure that everyone is treated fairly and is given a chance to defend themselves in court.

An ex post facto law prevents laws from being applied retroactively. This is important to ensure that citizens cannot be punished for something they did before it was declared illegal.

The writ of habeas corpus prevents people from being held indefinitely without a trial. This is important to protect citizens against arbitrary detentions and ensure that everyone is given a chance to have their case heard in court.

When these rights are not protected, citizens are at risk of having their rights violated. This could lead to wrongful convictions, unfair punishments, and arbitrary detentions. Therefore, it is important for Congress to abide by the Constitution and not pass bills of attainder, ex post facto laws, or suspend the writ of habeas corpus.
