There is no official publisher of the complete New Hampshire Code of Administrative Rules. Each agency prints its own rules, and the state office that receives every rule filing publishes none of them.
The copy you read online carries the same caveat. The office states that rules on its website are not the official version under RSA 541-A, because the format differs, because a later filing may not be certified yet, and because an online rule may have expired.
Where the official text actually sits
RSA 541-A:15, I sets the sequence. An agency files the adopted rule with the director of legislative services, and that as-filed text is the official version. The director then sends the agency an edited draft, the agency has 60 days to certify that the edit says the same thing in substance, and the certified version becomes official from that point. Miss the 60 days and agreement is presumed.
So a New Hampshire rule has two possible official texts across its life, and which one governs depends on whether certification has happened. The office will send you a copy of the official version of a currently effective rule on request. For anything you plan to litigate, ask for it.
That publishing arrangement also explains the shape of the state's law. There are 38,515 regulation sections against 25,375 statute sections in New Hampshire, so the rule book outweighs the statute book by half again.
Rules die on a clock
RSA 541-A:17, I: "No rule shall be effective for a period of longer than 10 years except as extended pursuant to RSA 541-A:14-a." An agency can adopt an identical rule and start the ten years over, and while a readoption is running, existing rules that would otherwise lapse stay in effect until the new ones take effect. If the agency then misses a deadline in that readoption, those rules expire 30 days after the deadline.
Organizational and procedural rules are the exception. Under paragraph II, once the committee has approved them they do not expire, though a statutory change that makes them inaccurate expires them one year later.
An expired rule binds nobody. RSA 541-A:22, I says no agency rule is valid or effective against any person or party, nor may it be enforced by the state for any purpose, until it has been filed as required and has not expired. The same paragraph orders refunds of fines and fees an agency collected under an expired rule.
Of the state's 38,515 regulation sections, 1,223 carry an expired status, 173 are repealed, 311 are reserved and 28 were renumbered. The expired ones are the reason you check the source note before you rely on anything. The rules office deletes expired rules or marks their source notes "Expired" once it learns of the expiry, and that word "once" is doing work. There is a window where the page still looks live.
Reading a rule address
Open Chapter Env-Wq 1000 and the structure is on the page. A subtitle prefix made of letters, Env-Wq for water quality inside Environmental Services. Then a chapter number, 1000. Then parts, Env-Wq 1001 and up. Then sections inside the part.
The history is kept by document number. The chapter's revision note records that Document #9086, effective 2-9-08, readopted and renumbered the former Chapter Env-Ws 1000 as Env-Wq 1000, under a reorganisation plan for the department's rules approved by the director of legislative services on 9-7-05. An older list under the same note runs back to Document #611, effective 2-10-75, and includes entries like "#6329, INTERIM, eff 9-6-96, EXPIRED: 1-4-97."
Two things follow. A cite to Env-Ws 1000 still points at live law. Those are the same rules at their old address. And a New Hampshire rule's identity in the filings is its document number, so that is the string to search when you need what the rule said on a past date.
The statute cite uses a colon
RSA 541-A:17, I is chapter 541-A, section 17, paragraph I. The colon separates chapter from section, and paragraphs are Roman numerals. Anything that treats the colon as a subsection divider will mangle it.
Then read the source line at the foot of a section. RSA 21:3 ends with: "Source. RS 1:1, 2. CS 1:1, 2. GS 1:3. GL 1:3. PS 2:3. PL 2:3. RL 7:3. 2014, 160:4, eff. July 10, 2014." Those are earlier compilations, each with its own colon numbering, and each is a real address for the same provision in an older book. A nineteenth-century New Hampshire brief citing GS 1:3 is citing what you now read as RSA 21:3.
Cases carry a year and an opinion number
Supreme Court Rule 20(5) governs. Citations to the court's own opinions go to the New Hampshire Reports, except that an opinion issued after January 1, 2024 is cited either in neutral form, given in the rule as State v. Shea, 2024 N.H. 1, or to the New Hampshire Reports if it has been published there. Year, jurisdiction, opinion number, and pinpoints by paragraph.
Rule 20(3) covers the other pile. An order disposing of a briefed case with no opinion has no precedential value, and it may still be cited or referenced in any court in the state, so long as it is identified as a non-precedential order, was issued in a non-confidential case, and the citation gives the court, docket number and date. On claim preclusion and law of the case it is controlling. Would you have cited it? Most people assume an order with no opinion is unusable.
The constitution keeps its holes numbered
New Hampshire has been running the same constitution since it took effect on June 2, 1784, and repealed articles stay in the printed sequence with their numbers. Part Second, article 10 reads, in full, "[Repealed, 1889.]" That is the whole entry. Of 157 constitutional sections, 146 are in force and 11 are repealed, and every one of those eleven still holds its slot, so article numbering never shifts under an old citation.
What to watch
Check whether a rule has been certified before you quote it, since certification decides which text is official.
Check the expiry before you advise anyone. Ten years is the outer limit and the readoption cycle is where the surprises live.
And when a rule looks missing, look for the reorganisation. New Hampshire moves whole subtitles under a plan approved by the director, and the document numbers are the thread back.
