After the Boston Tea Party occurred, British Parliament passed several laws that were used to help prevent similar events from occurring again. They also passed several bills that protected their royal officials in the New World from prosecution as a result of the ensuing riots.
One of the most important bills imposed by Parliament at the time of the Boston Tea Party was a bill that prohibited ships from being loaded and unloaded in Boston's harbors. This made it difficult for merchants as well as ships and greatly affected the local economy and the way business was done in Boston at the time. The entire Massachusetts colony was affected by the new regulations on elected officials. The crown was responsible for electing government officials, which made the Massachusetts government charters essentially defunct and left the people at the mercy of the British.
British officials were protected by the British government at the time of the Tea Party, but Parliament put a new bill into law after the event. This bill would allow any royal officials who were within the colonies at the time to transfer their court cases to royal court in England where they would be treated with more respect and kindness.
