Beacon Hill 101

Start of the Legislative Session
At the start of the legislative session, bills are filed, legislators and bills are assigned to committees, and the rules for each chamber (and the two chambers acting jointly) are voted on.

Legislative sessions last two years – the session begins in odd-numbered years, and ends in even-numbered years.
The Committee Process
Every bill that is filed will receive a hearing from the relevant subject matter committee. Organizations and members of the public are invited to submit testimony. In a number of other states, this testimony is made available to the public (with appropriate redactions). Massachusetts should join them.
Budget Season
The Governor submits a budget to the Legislature in late January. The House will take up consideration of the budget in April, and the Senate in May, with the goal of passing a consensus budget by the end of June.

Your legislators might tell you that they can’t pass policy through the budget. They do it all the time.
Floor Debate
When a bill finally makes it out of committee and is set to be debated on the floor, legislators have a brief window to file amendments to add, eliminate, or rewrite parts of the bill.

Which of these amendments will actually make it into the bill is often predetermined--decided by Leadership before the floor debate begins.
After a Bill Passes
If the House and Senate pass the same version of a bill, then it goes to the Governor.

If they pass different versions of a bill, the two chambers appoint a Conference Committee – a committee of six members to negotiate a consensus version of the bill.

Even though, in most years, there is not much legislative action in the final months of the year, the fall and early winter are still an important time for advocates and coalitions to start brainstorming and strategizing for the next legislative session, as well as to reflect on the recent session (what worked, what didn’t, etc.)

(or any other odd-numbered year)

The legislative session begins on the first Wednesday of the year following an election (i.e., each odd-numbered year). After the session begins, legislators file bills. Most bills are filed during this early period, although bills can still be introduced later (“late files”). Legislators are given positions (member, vice chair, or chair) of committees to handle different areas of work (e.g., Education, Health Care Financing, etc.), and bills are assigned to relevant subject matter committees.

At this point, each chamber also votes on a set of rules to govern their functioning for the session, and the two chambers vote on a set of joint rules as well.

There are 33 joint committees in the Legislature, as well as 11 Senate-only and House-only committees. Given that each body has its own rules and its own budget process, the Rules Committee and Ways & Means Committees often operate independently rather than jointly (even though they exist as both). 

This means that the House Speaker and Senate President each have 41 chairs and 41 vice-chairs to assign. Because chairs and vice chairs come with extra staff, space, pay, and resources, the roles create a dynamic in which legislators can easily drift toward seeing the Leadership in their respective chamber as their “boss” (rather than viewing their constituents, who elect them, as their boss).

This competition for leadership positions also illuminates one distinction between the House and the Senate. In the 40-member Senate, every member of the majority party can chair at least one committee. In the 160-member House, state representatives vie for positions in a state of scarcity–not everyone can get one. That scarcity breeds centralization: 88 chairs and vice chairs, a Majority Leader, and a Speaker Pro Tempore (setting aside any other Leadership positions) gives a Speaker more than enough votes to stay in power. 

NB: Members of the House and Senate Leadership teams typically refrain from co-sponsoring bills. They still need to hear from you.

Every bill that is filed will receive a hearing from the relevant subject matter committee, and the committee will not vote on whether to advance the bill until after the hearing. Organizations and members of the public are invited to submit testimony. In a number of other states, this testimony is made available to the public (with appropriate redactions). Massachusetts should join them. 

Committees have until the first Thursday in February of the second year of the session (“Joint Rule 10 Day”) to take action on a bill. That means that hearings will happen before then, and the earlier the hearing, the better odds of avoiding a bottleneck around the deadline. Note, of course, that “action” by the committee can include an extension order which provides the committee more time to discuss the bill.

You can find video footage of some past hearings here. 

You can view the composition of House, Senate, and Joint (House-Senate) committees here. 

Making it out of the subject matter committee (Housing, Judiciary, Health Care Financing, etc.) is only step #1 for a bill. Many bills get reported favorably out of the subject matter committee and then die in the graveyard that is the Ways & Means Committee (through which any bill involving money must pass) or the Committee on Third Reading (which “perfects” bills before the floor–eliminating errors, ensuring constitutionality, and making other changes as they see fit) rather than ever making it to the floor.  

Committees can drastically rewrite a bill before sending it to the next step — indeed, the most moneyed interests always find a way to pry behind the closed doors where text is negotiated. Always check the language.

Although the Legislature goes into recess after November 15 during odd-numbered years for an end-of-year break, committees can still hold hearings then. There are just no floor votes during the end of the year.

The Legislature also goes into recess after July 31 on even-numbered years, even though the session technically extends through the rest of the year. Committees can still report out bills in the remaining months of the session, but they can only pass if there is unanimous consent (i.e., no one present objects to their passage).

The Governor must submit their budget no later than the fourth Wednesday of the year—unless it is the first year of said Governor’s first term, in which case the budget must be submitted no later than the ninth Wednesday of the year. The House then takes up consideration of the budget in April, and the Senate in May, with the goal of passing a consensus budget by the end of June. The Ways & Means Committee in each chamber is in charge of drafting the budget.

Your legislators will probably say that there “isn’t enough money” to invest at the level that we need to. They’re wrong

Your legislators might tell you that they can’t pass policy through the budget. They do it all the time. 

When a bill finally makes it out of committee and is set to be debated on the floor, legislators have a brief window to file amendments to add, eliminate, or rewrite parts of the bill. 

Which of these amendments will actually make it into the bill is often predetermined–decided by Leadership before the floor debate begins. 

The actual debate on the floor of either chamber is rare (and especially rare in the House), and House and Senate Leadership often directly or indirectly pressure legislators into withdrawing their amendments. 

When you see the House or Senate go into a quick recess during floor debate, that’s because negotiations are happening about how to ensure the smooth passage or rejection of an amendment in line with Leadership’s intent. These “quick” recesses can sometimes be hours long. 

Most amendments do not receive an actual recorded vote. In some cases, this is okay (if everyone supports your amendment to increase the parks budget, do we really need a vote?), but in many cases, it obscures the process and prevents the accountability of knowing support and opposition. 

Never assume your legislators will vote the way you expect. Legislators have at times voted against bills or amendments they sponsored or co-sponsored due to pressure from Leadership.

If the House and Senate pass the same version of a bill, then it goes to the Governor. 

If they pass different versions of a bill, one chamber can choose to just pass the other’s text. If there is gridlock instead, the two chambers appoint a Conference Committee — a committee of six members (3 from either chamber, 2 from the majority party and 1 from the minority party) to negotiate a consensus version of the bill. Conference Committees operate like a black box, with no public record of their meetings or the state of negotiations, although you can still try to influence them.

When the Conference Committee produces a report, it gets scheduled for a vote. [See “Floor Debate.”] However, the House and Senate can only choose to vote yes or no on the Conference Committee report; they can no longer amend it.

When the bill gets sent to the Governor, the Governor can choose one of five steps: 

  1. The Governor can sign the bill, and it becomes law. 
  2. The Governor can veto the bill, which the House and Senate can override with a ⅔ vote. 
  3. The Governor can do nothing. If the Legislature is in formal session, the bill would become law without the Governor’s signature after ten days. If, however, the Legislature is not in formal session, then the bill fails; this is called a pocket veto. 
  4. The Governor can issue line item vetoes, rejecting specific parts of an appropriations bill. The Legislature, again, can override with a ⅔ vote.
  5. He can send back amendments, requesting specific changes to the bill text. The Legislature can choose to accept or reject them.
