Don,
I did some further searching, and this is what I found, on
http://www.cga.ct.gov/hco/eob.htm
"Action by the Governor
If the Governor receives the bill while the legislature is in session, he has five calendar days, exclusive of Sundays and holidays, in which to sign it or return it to the house in which it originated with a statement of his objections. In the latter case, the bill may be reconsidered and, if passed by at least two-thirds of the members of each house of the General Assembly, it becomes law. If the Governor does not sign or veto the bill within five calendar days after the same has been presented to him, Sundays and holidays excepted, it automatically becomes law unless the General Assembly has adjourned the regular or special session. If the regular or special session has adjourned, the bill becomes law unless the Governor, within fifteen calendar days after it has been presented to him, transmits it to the Secretary of the State with his objections."
So, unless Gov. Rell has responded to the Secretary of State with objections, it would appear to be law no later than the July 1st enactment date!
