Massachusetts Legal Research

A guide to selected sources for Massachusetts legal and law-related information.



This guide is designed to highlight selected resources for doing legal research in Massachusetts. It is designed primarily for Harvard Law School students, staff and faculty.    At present,  it focuses on Massachusetts state materials and not materials related to the federal courts in Massachusetts.

Much of our Massachusetts collection is on the 4th floor of Langdell, but much is stored offsite in the Harvard Depository, in Reference, in Special Collections, on microfilm/microfiche or shelved elsewhere.  Increasingly, we are acquiring more of our Massachusetts materials in electronic format.  This guide is intended as a starting place to highlight some of the more popular resources we have.  Check Hollis for more materials.

An amazing resource for Massachusetts legal information is the Massachusetts Trial Court Law Libraries.  They are also open to members of the public and are happy to help them with research questions.

Massachusetts Supreme Judicial Court Cases

Note: For SJC cases from 1822-1867, the volumes of official reports were named for the repoter (e.g. Pick. for Pickering).  Section 2.02 SJC Style Manual provides guidance for using citations with these reporter names and also provides a table that converts Mass. Reports citations to these nominative reporter citations in Appendix 3.

Massachusetts Appeals Court Cases

Massachusetts Appeals Court cases are officially published in the Massachusetts Appeals Court reports by the Office of the Reporter for Judicial Decisions and in the Northeastern Reporter.

The court also issues "unpublished" orders under Rule 1:28 (known as "Rule 1:28 orders").  A court decision and rule change has made it possible to cite them in some circumstances.  The rule change: "If, in a brief or other filing, a party cites to an order issued under this rule, the party shall cite the case title, a citation to the Appeals Court Reports where issuance of the order is noted, and a notation that the order was issued pursuant to this rule; in addition, a party citing such an order shall include the full text of the order as an addendum to the brief or other filing. No such order issued before February 26, 2008, may be cited."

Constitutional law


The Massachusetts Constitution is the oldest written constitution in effect in the United States. It sets forth the rights of individuals in the "Declaration of Rights, Part I," and the form of government in "The Frame of the Government, Part II." The Constitution can be amended by a special constitutional convention, the legislature or by popular initiative. There are over 100 amendments in the "Articles of Amendment."



The Massachusetts legislature has one session per year. Laws that are enacted are published chronologically in the Massachusetts Acts and Resolves (session laws).     They are then arranged by subject in the general laws (code). See our Legislative History section for information about bills (laws that are not yet enacted).

Legislative History

Bill tracking

Full-text bills

Steps for doing a MA legislative history

1) Identify session law reference.  Consult the "historical notes" section of an annotated version of the Massachusetts General Laws for the particular statute you are researching.

2) Use the session law reference to identify bill number with one of the following:

  • Legislature website for laws enacted back to 2009/10
  • Westlaw  (back to 2005 in bill tracking/text and late 1980's for session laws) and Lexis (back to 1989 in bill tracking and 1990 in session laws)
  • Journal of the House of Representatives and Journal of the Senate (See House and Senate Journals below): For bills after 1973, a bill history summary is included in the final volume.  
  • session laws 
  • Bulletin of Committee Work (Harvard Depository 1915-1978): describes legislative committees' work through each session. In its yearly cumulative edition, it contains a table entitles "Acts and Resolves Approved by the Governor" which traces every session law back to its final bill number. 1925-1965 searchable in HathiTrust and GoogleBooks.
  • Guide to Massachusetts General and Special Acts (not held at Harvard, but held by other area libraries)(1972-2008)

3) The Legislative Package 

Once you have a bill number and year, you can look for the "legislative package." This package contains the original petition filed with the Senate or House clerk, which is a simple form, along with the bill itself, including the text. In some rare cases, a statement of intent may be filed with the bill, printed at the top of the bill.  All petitioner names appear on the bill, as well as handwritten changes made by committees that reviewed the bill. The State Archives at Columbia Point maintain the documents comprising the legislative package for each bill introduced in the General Court. For very recent bills, check the General Court's online information or contact the House or Senate clerk.

If the Governor has introduced a bill, a Governor's message will be filed with the House clerk and given a House bill number. Along with the proposed bill will be a "transmittal letter," which details the need for the bill. This is an extremely important document for determining intent of legislation, and is part of the legislative package.  Bills as proposed and filing letters of the current administration may be found on the governor's website.   Another source to examine when the Governor has proposed legislation is the annual message of the Governor, a program in accordance with which the governor may initiate bills throughout the legislative sessions, may be detailed. The annual message of the Governor is printed as Senate Bill 1 in the first year of a legislative session. The bill number varies in the second session.

Administrative agencies may file proposed legislation. The agencies' recommendations come with bill drafts, and are printed as the first series of bills within a year.

Special commissions may propose legislation as an appendix to a mandated report. Special Commission Reports may have House or Senate bill numbers. There is an index to Special Commission Reports, Index of Special Reports Authorized by the General Court (1900-1988) and Index to Special Reports (1988-March 1994).  The New England Law Boston Library has a selection of these reports on its website, as well as the  Massachusetts State Library.  Also, check HOLLIS to see which Special Commission Reports are available at Harvard libraries. You might also check the Official Publications of the Commonwealth of Massachusetts.




Committee hearings and debates

The indexes in each volume of the Journal of the House and the Journal of the Senate (see below) provide important information about the bill history which may lead to other material relevant to the bill's intent, including the committee assignment of the bill, the date of public hearings, and the dates of debate on the chamber floor. If the bill is from the current session, a bill history may be available online.

Bills introduced into the House or Senate are referred to committees whose topics most closely align with that of the bill. Public hearings must be held on every bill referred to a committee. Videotapes of selected hearings produced by WGBH, the local PBS station, under contract with the General Court, are official sources for those hearings.  These videotapes are catalogued and searchable at the State Library. Selective committee hearings from 2007 on appear on the legislative website.   The State House News Service is an unofficial print and electronic source of selected hearings. Written testimony submitted to the committee for hearings are included in bill folders, which may or may not be deposited by the committee in the State Archives. The committee should be contacted directly to determine if that is its practice.  

If the bill is favorably reported out to the first committee, it received its "first reading" and goes to any other committee it may have to be sent on to. If it survives, it receives a "second reading", which means that there is the opportunity for debate on the floor of the chambers. This is an important step for researchers in determining the intent of the bill. The State Library has the official audiotape and videotape records of the proceedings of the House, which includes these floor debates, beginning in November 1984. Senate proceedings are available from 1994. The unofficial State House News Service has transcribed debates since 1972. However, do not be surprised if the "debate" is extremely brief.   

Masstrac/Instatrac has transcripts (written and recorded) back to the mid-2000's.  

After the "second reading" procedural step, members of the chamber are asked if the bill should go to the Committee on Third Readings (House or Senate). If the bill is sent to the Committee, it may undergo technical changes, change in citation form or even review for Constitutional issues. The bill is then sent back to the chamber floor where it may be debated again. If amendments are made, the bill will be sent back to the Committee on Third Readings (House or Senate) for re-examination. If the bill "passed to be engrossed," it is sent on to the other chamber to undergo the same process all over again.

Governor materials

If both chambers of the legislature enact the bill, it is sent along to the Governor's Office for approval. The Governor's staff prepares a summary analysis of the bill, including its impact if passed. These papers constitute the Governor's Legislative Files. During the Governor's term of office, these may be obtained from the Governor's Office. The papers of previous administrations may be obtained from the State Archives. These papers do not provide evidence of legislative intent because they issue from the executive office. If the Governor returns the bill with amendment, it takes the form of a "Governor's Message" and becomes a bill itself. A transmittal letter will accompany the amendment, which does provide evidence of legislative intent.

Another set of sources issuing from the Governor's office which may provide direct or indirect evidence of the intent of legislation are Governor's press releases from around the date of the signing of the bill by the Governor. These are available at the State Library, dating from 1958.  Recent releases appear on the the government website.

Other materials

Other less formal means of gleaning information relevant to legislative intent include contacting the original petitioners for the bill, whether sponsoring legislators or members of special organizations. The names of the original petitioners appear on the original petition in the legislative package. Also, do not forget to examine newspapers for clues about the social conditions out of which the idea for the legislation sprang.

  • executive orders,
  • Attorney General opinions, and
  • notices of public interest (e.g., additions to the State Register of Historic Places).

Code of Massachusetts Regulations

Note that the Code of Massachusetts Regulations did not start until 1976. 

There is no official subject index to the CMR published by the Secretary of State, but there are Weil's Index to the Code of Massachusetts Regulations and the Massachusetts Trial Court Law Libraries' index.  

Regulations in the CMR may be updated by "emergency regulations" published in the Massachusetts Register.
