The Continental Association went into effect on December 1, 1774. The ban did succeed for the time it was in effect. However, the British did retaliate by blocking colony access to the North Atlantic Fishing Area.
Only one colony failed to establish local enforcement committees; in the others, the restrictions were dutifully enforced—by violent measures on some occasions. Trade with Britain subsequently plummeted. Parliament responded by passing the New England Restraining Act, which prohibited the northeastern colonies from trading with anyone but Britain and the British West Indies, and they barred colonial ships from the North Atlantic fisheries. These punitive measures were later extended to most of the other colonies as well.
The outbreak of open fighting between the colonists and British soldiers in April 1775 rendered moot any attempt to indirectly change British policies. In this regard, the Association failed to determine events in the way that it was designed—Britain did not cave to American demands but instead tried to tighten its grip, and the conflict escalated to war. However, the true long-term success of the Association was in its effective direction of collective action among the colonies and expression of their common interests. This recognition of union by the Articles, and its firm stance that the colonies and their people had rights that were being infringed by Britain, made it a direct precursor to the 1776 Declaration of Independence, which by contrast repudiated the authority of the king once it was clear that no other solution would preserve the asserted rights of the colonies.
