Massachusetts Chapter 30A: Administrative Procedure Act

Massachusetts General Laws Chapter 30A is the state’s Administrative Procedure Act. It sets the rules every state agency has to follow when it writes a regulation, holds a hearing that affects your rights, or issues a decision you want to challenge in court.¹ If you are dealing with a state board, commission, or department, this is the statute that tells you what process the agency owes you and what you can do if it cuts corners.

Which Agencies Chapter 30A Covers

The statute reaches any state department, board, commission, division, authority, or official with power to adopt regulations or hold adjudicatory proceedings.¹ That is a wide net, from the Department of Environmental Protection to the Board of Registration in Medicine.

A handful of bodies are expressly carved out: the Legislature, the courts, the Governor and Council, military boards, the Department of Correction, the Department of Youth Services, the Parole Board, the dispute resolution division of the Division of Industrial Accidents, the Personnel Administrator, the Civil Service Commission, and the Appellate Tax Board.¹ If your matter is in front of one of these, Chapter 30A does not govern and a different procedural scheme applies.

What the Law Requires When an Agency Writes a Regulation

Chapter 30A splits rulemaking into two tracks. A public hearing is required when the proposed regulation could expose someone to a fine or imprisonment, when the agency’s enabling statute or another law demands a hearing, or when a constitutional right requires one.² For other regulations, the agency uses a notice-and-comment process under Section 3 that does not require a live hearing.

When a hearing is required, the agency has to give at least 21 days’ notice unless another law sets a different timeline. Notice goes out by newspaper or trade publication, to anyone who has asked in writing to be notified of rulemaking hearings, and is filed with the Secretary of the Commonwealth. The notice must cite the statutory authority for the rule, state the time and place, and either print the full text or describe its substance.²

Before any regulation takes effect, the agency files two attested copies with the Secretary of the Commonwealth, along with the statutory authority and any required approvals. It also has to file a fiscal impact estimate covering the first two years and a five-year projection, or a statement that there is no fiscal effect.³

Section 5 adds a small business impact statement for most regulations, with rate-setting rules the only exception. The agency has to consider less burdensome alternatives, including lighter compliance requirements, flexible deadlines, consolidated reporting, performance-based standards, and the rule’s effect on new business formation in Massachusetts. If an agency skips the statement entirely, you can enforce the requirement through a civil action for mandamus relief, though you cannot invalidate the regulation by attacking the quality of the statement itself.³

Your Rights in an Adjudicatory Hearing

An adjudicatory proceeding is a hearing where an agency decides the legal rights, duties, or privileges of a specifically named person, and where a constitutional right or statute entitles that person to a hearing.¹ License revocations, benefit denials, and enforcement actions typically qualify. The statute entitles every party to a “full and fair hearing.”⁴

Under the state’s Standard Adjudicatory Rules of Practice and Procedure, your notice of hearing has to tell you the date, time, and place, explain the hearing procedure, and describe the issues with enough detail that you can prepare. You can represent yourself or bring an attorney or other authorized representative at your own expense. You can call witnesses, submit documents, and cross-examine the agency’s witnesses.⁵

Not every case goes the distance. Section 10 lets agencies resolve matters informally through stipulation, settlement, consent order, or default, and parties can agree to narrow the issues or modify procedures.⁴ If you are not a named party but the outcome could substantially affect you, you can ask to intervene.

Hearings run on relaxed evidence rules. The strict courtroom rules do not apply, hearsay is generally admissible, and the presiding officer weighs it accordingly. That cuts both ways. You can introduce material a court might exclude, and so can the agency.

The Written Decision

Every agency decision has to be in writing or stated in the record, with a statement of reasons covering each issue of fact and law that drove the result, unless a statute allows the agency to skip written reasons absent a timely request.⁶ This matters. Without reasoning on paper, there is no way to test whether the agency actually weighed the evidence.

The agency has to notify every party of the decision, the right to appeal within the agency or in court, and the deadline for doing so.⁶ A copy of the decision and reasoning goes to each party and their attorney on request. Read the notice as soon as you get it. The appeal clock starts the moment it reaches you.

Appealing an Agency Decision to Superior Court

Section 14 gives you the right to challenge a final agency decision in Superior Court, unless a specific statute expressly bars judicial review. You have to be a “person or appointing authority aggrieved” by the decision, meaning the agency’s action directly harmed your legal rights or interests, and the decision has to be final. If the agency offers an internal rehearing or appeal, you generally have to use it before heading to court.⁷

Grounds for Overturning a Decision

The court does not retry the case. It reviews the record and can set aside or modify the decision only if the agency went wrong in a specific way:

The decision violates a constitutional right.
The agency acted beyond its statutory authority.
The agency misinterpreted or misapplied the law.
The agency failed to follow legally required procedures.
The decision is unsupported by substantial evidence in the record.
The decision is arbitrary or capricious, an abuse of discretion, or otherwise not in accordance with law.

The court can also make independent factual findings when the constitution requires it, and can compel agency action that was unlawfully withheld or unreasonably delayed.⁷ Most challenges live or die on substantial evidence and arbitrary-or-capricious review. Substantial evidence is a low bar for the agency, but a real one. The record has to contain something a reasonable mind would accept, not just the conclusion the agency preferred.

Deadline, Filing, and Fees

You have 30 days from receiving notice of the final decision to file in Superior Court. If you filed a timely petition for rehearing with the agency, the 30 days restart when you receive notice that the petition was denied. The court can extend the deadline for good cause, but only if you apply within the original 30-day window or an extension already granted.⁷ Mail it late and the court will dismiss, even if you dropped it in the mailbox before the deadline.⁸

You can file in the Superior Court for the county where you live or have your principal place of business, the county where the agency has its principal office, or Suffolk County.⁷ The filing fee is $240, plus a $20 security fee and a $15 surcharge, for a total of $275.⁹ You serve the agency and every party to the original proceeding under the Massachusetts Rules of Civil Procedure, and the agency has to certify the names and addresses on request. Other parties from the agency case can intervene as of right, and the court may let other interested persons join.

The Agency Can Still Enforce While You Appeal

Filing for judicial review does not automatically stop enforcement. This surprises people. If the agency revoked your license or imposed a penalty, that stays in place while your appeal moves through the courts unless someone grants a stay. The agency can choose to stay enforcement itself, and the reviewing court can order a stay on whatever terms it thinks appropriate.⁷ If the agency’s action will cause you serious harm while the case is pending, ask for a stay early.

Where to Read the Regulations

Agency regulations are permanently recorded in the Code of Massachusetts Regulations, which Chapter 30A established.¹⁰ New and amended regulations appear first in the Massachusetts Register, published every two weeks.¹¹ If you are tracking a recent change, check the Register first, since updates take time to be folded into the CMR. Both are available through the Secretary of the Commonwealth’s office, and public libraries typically carry copies.
