The best term to describe the system would be weak.

The first form of government used in the United States was the confederation. This was an agreement between the original thirteen states, which featured an extremely limited federal government. The states were governed by the Articles of Confederation. While this form of government enabled the new government to manage the Revolutionary War, it did not work well the once the Americans defeated the British. This necessitated the drafting of a formal constitution, which featured a strong federal government.

it was certainly a debatable decision, mainly because it was based primarily on political - and not on legal or social - views. since the congress at that time was led by members of the republican party, and the territory that the tribes wanted to turn into an exclusively indian state was predominantly democratic, the proposal (as expressed in the constitution) did not succeed, but the constitution itself proved to be of crucial importance in the creation of the state of oklahoma, and, most importantly, it guaranteed the involvement of representatives of the indian tribes in the government of the future joint state.  

as a member of congress, i would have voted to ratify the constitution, or at least to have it tabled. ignoring it was an interested and partial decision.
