The stamp Act congress said it was okay for colonial legislatures to tax the colonist but not parliament because the colonists didn’t have representation in the parliament.
Step-by-step explanation:
The parliament of Great Britain imposed Stamp tax on the British colonies in North America in order to bring the colonies under its direct tax system.
This act instructed that all the printed material in the colonies have to use stamped London made stamped paper. Printed materials like magazines, newspapers, documents, playing cards etc had to bear revenue stamp.
The colonists found this act unfair. The tax was imposed by the British parliament where the colonists had no representation. They thought that only the colonial legislature had the right to make laws for the colonies.
