Final answer:
The lack of a federal court system from 1781-1789 was bad for the United States as it led to inconsistencies in the interpretation and enforcement of national laws. This problem was addressed with the ratification of the Constitution and the establishment of federal courts.
Step-by-step explanation:
The lack of a federal court system from 1781-1789 was a bad thing for the United States because it created a lack of consistency in the interpretation and enforcement of national laws. Without a national judiciary, each state was free to interpret and enforce laws as they saw fit, which often led to disputes and favoritism towards the state in which the court was located. This problem was addressed with the ratification of the Constitution, which granted Congress the power to create lower federal courts and established the Supreme Court. The Judiciary Act of 1789 further established the number of Supreme Court justices and created lower federal courts.
