How a Bill Becomes Law in Hawaiʻi

This guide walks through the life of a bill from introduction to becoming law (or not). It also explains the language we use in daily State Bill updates on this website, or when we ask you to take action in our newsletter.

Also see our list of Committee and Procedural Abbreviations.

Step 1: Introduction and first reading

Any member of the Hawaiʻi State Legislature can introduce a bill. Bills introduced in the House start with "HB"; bills introduced in the Senate start with "SB." When a bill is introduced, it gets its 1st Reading: it's formally presented to the full chamber and assigned to one or more committees.

Step 2: Committee review

This is where most of the real work happens — and where most bills die.

Each committee assigned to a bill schedules a hearing. Public notice is typically issued 48 hours in advance (sometimes longer in the Senate). This is your opportunity to submit testimony, which must generally be submitted at least 24 hours before the hearing via the legislative website.

After the hearing, the committee votes on what to do with the bill. You'll see a few possible outcomes:

Passed or Passed with amendments means the committee approved the bill and sent it forward. Most bills that survive are amended along the way; that's normal and doesn't mean something went wrong.

Deferred or Held means the committee chose not to act on the bill. This is the most common way bills die — quietly, without a formal "no" vote. In fact, about 60% of bills fail simply because they aren't scheduled for a hearing before a deadline.

The committee chair's power: The committee chair decides whether a bill even gets a hearing. If a chair doesn't schedule a bill, it dies in committee. This is sometimes called "bottling up" a bill, and it's one way leadership can control which bills move forward.

If a bill is referred to more than one committee, it has to pass each one in sequence. Clearing JHA (Judiciary & Hawaiian Affairs) only to get deferred in FIN (the Finance Committee) is still a loss.

Step 3: Second reading and floor vote

Once a bill has passed all its committee assignments, it moves to a 2nd Reading before the full chamber. This is when the bill can be debated and further amended. A successful 2nd Reading moves the bill toward a final floor vote (3rd Reading), where the full House or Senate votes to pass or reject it.

Step 4: Crossover

If a bill passes one chamber, it crosses over to the other. A House bill goes to the Senate; a Senate bill goes to the House.

The whole process then starts again: new committee referrals, new hearings, new opportunities for testimony. This is why you'll sometimes see both "H:" and "S:" entries in a single bill's status history.

Step 5: Conference Committee

If both chambers pass the bill but with different versions, a Conference Committee is convened. This is a small joint group of House and Senate members (called conferees or managers) who negotiate a single unified version. You'll see "Conferees Appointed" when this stage begins. The resulting version is called a Conference Draft (CD1, CD2, etc.).

If the conferees reach agreement, the unified bill goes back to both chambers for a final vote. If they don't (or if the bill is "not heard by Conf. Comm."), the bill is effectively dead for that session.

Step 6: The Governor

Once a bill passes both chambers in the same version, it goes to the Governor, who can sign it into law (Enacted) or reject it (Vetoed). A vetoed bill can still become law if the Legislature overrides the veto with a two-thirds vote in both chambers, though this is rare.

A note on bill versions

As a bill is amended at each stage, it gets a new version label: HD1 (House Draft 1), SD2 (Senate Draft 2), and so on. When you see a bill listed as "HB1234 HD1 SD1," that tells you it has been through at least one round of amendments in each chamber. The version number doesn't indicate whether the bill is stronger or weaker than the original — just that it has changed.

Session timing: why bills can disappear suddenly

The Hawaiʻi Legislature convenes in January and adjourns in early May. The session operates on a schedule of approximately 60 legislative days (days the chambers are actually in session). Within that window, there are hard deadlines that determine whether a bill lives or dies — and understanding them explains why things sometimes go quiet or move fast.

First Crossover (March 12 in 2026) is an important deadline: by this date, every bill must have passed its third reading in its originating chamber, or it's "dead" for the session. This is why you'll see a flurry of committee hearings and floor votes in February and early March: everything has to clear before that cutoff. If a bill you care about hasn't moved by early March, it may already be running out of time.

After First Crossover, surviving bills move to the other chamber and the process starts again, with a new set of committee hearings and a second set of deadlines. Second Crossover (April 16 in 2026) is the deadline for bills to pass the non-originating chamber. Bills that make it through both crossovers are the ones that go to Conference Committee (if the two versions differ) or directly to the Governor.

Adjournment sine die (May 8 in 2026) is the formal end of session. "Sine die" is Latin for "without a day," meaning the Legislature adjourns without setting a date to reconvene. Any bills that haven't made it through by then are dead.

One important nuance: Hawaiʻi's Legislature operates on a two-year biennium (2025-2026). A bill that stalls in the first year (2025) doesn't automatically die; it can carry over and pick up where it left off in 2026. But at the end of 2026, anything that hasn't passed is done.

Why bills fail

Most bills never make it to the Governor's desk. Here are the most common reasons they fail:

• Not scheduled for a hearing: About 60% of bills die simply because they aren't scheduled for a hearing before a deadline.
• Funding: If a bill requires money but the Senate Finance (FIN) or House Ways and Means (WAM) committees don't include it in the budget, the bill dies.
• Committee chair bottleneck: Leadership or committee chairs may hold a bill to use as leverage for other priorities, or simply because they oppose it.
• Multiple committee referrals: If a bill is assigned to multiple committees, any one of them can fail to advance the measure.

What we track, and why

The IHSN Public Policy team updates the status of priority bills throughout the session; each topic of interest has one "issue owner," a person responsible for tracking bills for the issues assigned to them. We send action alerts (via email) when there's a specific step you can help with — such as an upcoming committee hearing that still needs testimony.

You can see the full list of bills we're currently tracking on this page (note that we stop updating them at the end of each legislative session in May). Find out how to submit testimony here.

If you'd like to join the Public Policy Action Group and receive these action alerts so you can let your voice be heard when it matters, you can read more or sign up here.
