How to Find and Cite Connecticut Law

Connecticut's regulations became official on the web in July 2017, and the printing stopped with it. The state's eRegulations System is now the official compilation of the Regulations of Connecticut State Agencies, and final approved regulations are no longer printed in the weekly Connecticut Law Journal.

You would not guess that from the site itself. Open the regulations search screen and look at the page source. A pop-up routine is still sitting in there carrying the old warning, that the database "is not an official legal edition of the RCSA" and that the official version is "the hard copy RCSA (in blue loose-leaf binders) published and printed by the Commission on Official Legal Publications, as amended by subsequent final approved regulations published and printed in the weekly Connecticut Law Journal." Nothing on the page calls that routine any more. The sentence just sits there, years past its expiry, and it gets copied into research notes.

The live rule is General Statutes § 4-173b. Once the Secretary of the State certified the system as technologically sufficient, the regulations published on it became the official compilation "for all purposes, including all legal and administrative proceedings." The Secretary ran that certification in the Law Journal on June 27, 2017, effective July 1. The same section tells the Secretary to update the compilation at least monthly.

Paper did not vanish. It changed jobs. Subsection (d) told the Secretary to have a plan by January 1, 2014 for keeping a paper copy, at the Secretary's own office, of everything posted on the system. The binder is a copy of the website now, not the other way round.

The day a Connecticut rule starts

General Statutes § 4-172 (b) puts the effective date on the posting. A regulation is effective when the Secretary of the State posts it, not when the agency adopted it and not when the review committee approved it. There are two carve-outs. A later date can be required by statute or written into the rule, and no rule beats the effective date of the act that authorized it.

Subsection (a) gives the Secretary ten calendar days from the agency's submission to get the text up. Those ten days are a real gap, where a regulation is approved, certified, submitted, and still not law.

The year on the statute book is not the year you think

The statute side runs on an older clock. The Legislative Commissioners' Office, a nonpartisan office of the General Assembly, codifies each session's public acts into the General Statutes and publishes the revision in January of odd-numbered years, with a supplement in the even ones.

The trap is on the front page of the statutes on the Assembly's own site. The header reads "Revised to January 1, 2025." Directly beneath it, a note tells you to check the 2026 Supplement, revised to January 1, 2026, for anything the 2025 sessions amended, repealed or added. So the year in the revision date is the date the text was cut, not the session it covers. Read the revision on its own and you are a full session behind. Ever quoted a subsection and had the other side quote different words back at you? Start here.

Two spellings, and the courts want the shorter one

Out of state you write Conn. Gen. Stat. § 14-212. Inside Connecticut you do not.

The Manual of Style for the Connecticut Courts, prepared by the Office of the Reporter of Judicial Decisions and adopted by the Supreme and Appellate Courts, gives the long form as General Statutes § 43-32, and it names the version it is rejecting in the same line: not "Connecticut General Statutes § 43-32." No state name. In a sentence you write Section 43-32 of the General Statutes.

Regulations get their own form, and it is not the acronym the portal uses everywhere. The Manual asks for Regs., Conn. State Agencies § 13-142-211 in a citation, and Section 13-142-211 of the Regulations of Connecticut State Agencies in a sentence. Court rules are the Practice Book, cited Practice Book § 43-22.

One more piece you will need eventually. When the governing text is an older revision, the revision goes inside the cite: General Statutes (Rev. to 2005) § 53-21. Drop that parenthesis and you have applied today's words to yesterday's conduct.

Reading a regulation number

Take one of the Manual's own examples, Regs., Conn. State Agencies § 14-63-36c (c). Chop it at the second hyphen and you get 14-63. Look that up in the General Statutes and you land on section 14-63, whose heading is "Regulations. Customer complaints. Stipulation by licensees." The regulation number opens with the statute section that authorizes it, then adds its own sequence.

That is worth turning into a habit. A Connecticut regulation citation usually hands you the enabling statute for free, before you have read a word of the rule.

The counts, and what the dead ones are doing

Our Connecticut set holds 36,974 sections across everything, 16,082 of them statutes and 18,012 regulations.

On the regulation side, 14,298 are in force. Another 3,098 are repealed and 309 transferred, and the eRegulations glossary says what those are for. The RCSA carries the text of currently effective sections plus history references to the numbers that were repealed or transferred. The number survives. The text does not. So a repealed regulation number is still a working address, and what comes back is a forwarding note rather than a rule.

Statutes run 15,942 in force. A repealed statute stays in the book as a stub. Pull up section 4-170a and the entire entry tells you that section 4-170a is repealed. Easy to skim straight past at speed.

Court rules come to 1,724 sections, 1,589 of them in force.

Three codes that are not in the official code

General Statutes § 4-173 lets the Secretary of the State leave five categories off the system. Two of them are documents incorporated by reference from somewhere else. The other three are whole codes, the State Building Code, the State Fire Prevention Code and the State Fire Safety Code. The Secretary may post a link to those instead, and the statute says in plain words that such a link is not part of the official compilation. Copies are kept for public inspection at the Department of Administrative Services.

Emergency regulations sit outside the RCSA too. The glossary gives the reason without ceremony. They are only temporarily effective, so they never get folded in.

So if the question in front of you is a building question or a fire question, the official compilation is the wrong book, and Connecticut wrote that into section 4-173 rather than leaving you to find out the hard way.
