Section 9

Section 9 - Limits on Congress

Before the year 1808, Congress could not stop states from allowing migration, or importation. But Congress could put a tax on importation (no more than $10 per person).
Congress cannot stop Habeas Corpus (meaning you cannot be imprisoned without reason and they are required to give a reason if you ask) except in cases of rebellion or invasion.
Congress cannot pass bills to make a crime already committed more punishable (Ex. a person who robbed a store, and afterward a law is passed for the death sentence for robbery, that person cannot be punished accordingly because the crime was committed before the bill was passed).
No Bill of Attainder can be passed (this takes away a person's civil rights, without a real trial).
Previously, taxes could not be made unless in proportion to the number of people, but that has been changed to where taxes can be laid without doing so proportionally.
No taxes can be made on exported material. No duties to be paid between states. States should not favor one state over another in regulation of commerce or revenue of ports.
Money cannot be taken from the Treasury unless needed to because of laws. A record must be kept of expenditures and it should be published.
No titles of Nobility will be granted and no person in office can accept a present, salary, office, or title from any king or prince unless Congress says it is ok.
