The date of passage of this resolution, like that of most contemporary laws and resolves adopted by the General Assembly of Connecticut, cannot be determined with certainty, as such acts were typically dated as of the first day of the session, regardless of the actual day on which they were voted. The status of the resolution was altered by An Act for confirming the Laws of this State as revised and amended, and for repealing such as are not contained in the foregoing Code, passed on or after 13 Jan 1784 by the General Assembly (Connecticut State Records, 5:281-282). A slightly edited version of this resolution was subsequently enacted as a law under the title An Act containing an Abstract and Declaration of the Rights and Privileges of the People of this State, and securing the same (Connecticut Session Laws, 1784, pp. 1-2).
Occasional references to "State of Connecticut" instead of "(English) Colony of Connecticut" are found in some official documents issued between 4 Jul 1776 and 10 Oct 1776, including a proclamation of Governor dated 6 Sep 1776.
In early references: State of Connecticut, in New England, in America and State of Connecticut, in America.
