This is already regularly done. One side or the other will propose or amend a bill that they claim does [popular thing x] and then add in some clause that they know will get voted against, so they can then claim that [other side] voted against [popular thing x].
This is often especially cynical because [popular thing x] is often something that neither party wants to pass. So a very recent example of this was an act against insider trading by politicians, that was bundled with a voter id law. Neither side wants to clamp down on insider trading from politicians, so the entire act was DOA. It was nothing but bread and circuses.

We need that too, but the ability to git diff changes to the law is a great win for democracy and transparency in 2026 because git is an interface that agents are experts at using.

In the present day, mainstream journalists won't be meaningful advocates for democracy and the public interest any time soon. It's time to acknowledge that this idea is wishful thinking. The root cause is changes to the law like the Telecom Act of 1996 which allowed for the consolidation of old media under a few corporations.

I'd actually argue that this is the wrong way around. Being able to git diff legislation is very good, but mainly for humans, who need tools to make work tractable.
An agent will use whatever interface is available, including no interference, won't give up due to the task being too onerous, and can be scaled by paying for more tokens. It could simply brute force diff the raw text, writing bespoke Python and regexes, etc.
LLMs make brute forcing intellect possible. It's humans who need finely crafted tools.

Such a requirement would not do what you think it would. There would not be names legislator or even aids as commit authors. The commit authors would be members of the House Office of the Legislative Counsel[1].
The House Office of the Legislative Counsel is non-partisan, impartial, and confidential. Whether transparency has merit or not, tracking provenance would make the office partisan. Is more partisanship in government not a concern?
The second issue with transparency is that communication between legislators and legislative counsel member is subject to the attorney-client relationship. Breaking attorney-client privilege is a serious decision. Knowing how such a change would affect the organization and its members is not something to be taken lightly.
A more convincing argument for transparency would address impartiality and confidentiality. This is pretty clearly a Chesterton's fence type situation where advocating to change a system should anticipate criticisms. Addressing opposition preemptively is an implicit demonstration of knowing why the system exists which is table stakes for changing it.

French bills evolution versioned in git and visualized
The Law Factory: french bills as git, opendata and dataviz
https://www.lafabriquedelaloi.fr/
Poland has an official, somewhat manual version of this - the ISAP system.
Actual bills are written in the form of patches ("§1. In the law X paragraph 5, the words "such and such" are replaced with "this and that". §2. The law X paragraph 4 is striked. §3. After law X paragraph 8, a new paragraph 8a is added that says "etc. and so on".)
After a patch or a collection of patches are passed, they are combined together and a unified version of the law is published. These documents aren't technically the law, they just show a snapshot of what the law is at the specific moment.
ISAP system is an online collection of all bills that were passed, plus crosslinks between laws that change/supercede/otherwise interact with each other, plus current and archival unified versions, plus related administrative orders and other miscellanious documents. Makes looking up laws and changes to laws very easy.

I hadn't thought of using git to track the changes in legislation. This is a cool idea.
In Australia, I spent a bit of time trying to work out how to find which politician voted for what (both at state and federal level), so that when elections come, you can single out the individuals who voted for what legislation. I think AI may make this easier, but the challenge is in not spamming the "free and open" access to the online record of our legislation.
So far, it's probably a one-person $50K per year job to do this task manually, and the language of the public legislation record didn't lend itself easily to determining the laws or rights that actually changed when bills were passed into legislation. They are explicitly stated, but hard to distill with regexes, filters or other analysis tools (e.g. "Who voted to stop electric scooters going over 25km/h?") If you try reading the legislation, you will know what I mean.
"A complete and open record of the proceedings of our parliament" still needs people spend a good chunk of time interpreting and summarising it (e.g. the media, commentators, etc) which means it's a time-consuming hobby or a paid gig.

That's an interesting project - I am guessing it's only targeting federal level, but could also include state level
The first problem I have in my mind is proxy votes, and votes that are made mandatory by the party they belong to - eg. a backbencher would struggle to go against the wishes of their party unless they felt it was worth risking their career over

Transparency has a cost. There are several good reasons, but my favorite is intellectual freedom. Policy makers would be much less likely to explore bold reforms or risky bipartisan compromises if their draft quality notes and correspondences were publicly tied to their political reputation. It takes significant work to produce successful legislation, and much of that work can be productively and safely done without direct public oversight. This is the same reason an individual might value a private journal.

> Policy makers would be much less likely to explore bold reforms or risky bipartisan compromises if their draft quality notes and correspondences were publicly tied to their political reputation.
Only if those bold reforms weren't in the interests of the people they serve. Risky bipartisan compromises should still be transparent along with what was gained in exchange for them. If the people feel that the compromise wasn't worth it they should be empowered to vote accordingly come election time. It's the job of representatives to assure the people who elected them that they are doing a good job and if they can't do that they deserve to lose their position. Refusing to support bold reforms that the people they represent want, or refusing to compromise when it would be beneficial to voters would become just as costly to their career.
> It takes significant work to produce successful legislation, and much of that work can be productively and safely done without direct public oversight.
Often most of that work is done entirely for them by corporations and lobbying groups and "law makers" just vote how they are paid to vote without even reading the bill put before them. Just because something can be done in secrecy doesn't make that the ideal way to do it. We've have extremely poor results with the system as it stands right now, so a change to introduce more transparency and accountability seems like a very good idea.
> This is the same reason an individual might value a private journal.
A public servant representing the people by making edits to laws and performing the duties they were elected to carry out is nothing at all like someone keeping a private journal. Their work is not their personal affairs, it is the public's affairs. How that work is being done matters to the public. Legislators would still remain free to go home at the end of the day and write in their private diary all they like.
> If you have a problem with your representative’s behavior, call their office and ask about it.
When their behavior is conducted in secrecy behind closed doors the public doesn't have the ability to hold them accountable for it, which is exactly why it takes place in secrecy. Increasing the public's ability to hold elected officials accountable by increasing transparency can only improve outcomes for voters, and it would certainty be inconvenient for elected officials who want to put their own interests above the interests of the people who elected them.

Likewise, a younger, more idealistic me thought it'd be great to use a GitHub-esque platform for laws. Pull Requests to suggest laws, gated behind reviews/approvals, branches so each house could work on their own versions before finally reconciling and merging into the Code, literally.

Something akin to this is a big part of the products that companies like LexisNexis or Thompson Reuters charge your lawyers a whole lot of money for. Because for a lot of legal questions, you don't just need to know what the law says now, but what it said at the time of the incident in question. And every legislative body around the country (at least at the time I was working in this space a decade ago) publishes legislative changes in completely different and often times not easily parsable forms. Web scraping and PDF scraping was far more common than you'd think. Some state legislatures published changes in more reasonable forms, and some states contract their official legislative compilation to companies like LexisNexis or Thompson Reuters and work to publish an actual change stream with proper standardized references. There's a lot of manual work that goes into making stuff like this work, a lot of lawyers and other legal professionals manually reviewing that the right pieces were removed or added in the right places, matching up references to parts of the law that might have changed between the time the legislation was passed and the time the change was published and figuring out what order everything actually goes in. And the actual text of the law is only part of the equation. Legal decisions from courts can dramatically impact the reading of the law, or effect effectively strike laws from the books (even if the laws are technically still on the books, just not enforceable). So often the right way to represent a diff of two points in time depends on the question you're trying to answer.

Following renumbers has to be one of the worst parts of this. As an example, the text of the US code that was modified by the BCRA in 2002 has been renumbered / moved since Citizens United v FEC was decided. But the text itself is the same as it was since the BCRA passed, because courts don't remove the actual law text with their decisions. So if you want to know what parts of the current US code were ruled unconstitutional by the courts in that decision and are therefore unenforceable, you need to first find the text of the BCRA, because the ruling refers to the sections of that piece of legislation. Then you need to find the version of the US code that was on the books when the BCRA was passed to find the section references that the law talks about. Then you need to find the law that renumbered that part of the US Code and find the new parts. Then you need to see if any changes have been applied since (there hasn't really) and then you need to match the changes to the referenced sections in the old version of the code to the equivalent text in the current version of the code, modulo any changes to references that changed as part of the renumbering but are otherwise the same.
I'm not saying lawyers aren't really really expensive, but you don't have to spend a long time digging into just a simple question like "what parts of the law are no longer enforceable after a supreme court decision" before you start to understand why they charge the prices they do.

In the interpretation of the law, yes, but that doesn't matter for version controlling the text of the law, and in that sense, you can absolutely manage the text pretty cleanly in git.

Nah, it's pretty damn common in any legal system.
If you've got a statute like "no vehicles in the park," the fundamental issue is that you have to interpret "what is meant by 'vehicle'?" and no legal drafting is going to be good enough to actually cover all the possible cases well enough. The main difference between a common law and a civil law system here is that in a common law system, you have to cite the previous similar cases (because precedent is binding) whereas in a civil law system, you're merely using those previous similar cases as persuasive evidence. At the end of the day, it boils down to arguing for your interpretation.
And in my experience working on language standardization (which is closer to a civil law system than a common law system), it's fairly often that I have to resort to looking up not just when a change in the text occurred, but dive deep into the discussions of the paper proposing the change to understand what the committee thought it was doing with the change. The complexity of law is fairly similar--the changes to the law themselves often require understanding the legislative and interpretative history of the law to understand what the intent of the drafter was to be able to rule on how the law is extended to an unanticipated scenario.

It depends on the question you're trying to answer. The text of the US law which Citizen's United struck down remains on the books today (though has changed since it was moved to a different part of the code, so references have been updated), but the actual effective law has most certainly changed from when it was written to now. Since courts can't write or modify the law, the literal text remains, even if some of that text is effectively stricken as if the text had been removed.
If you want to know the literal text (that may or may not be enforceable), then sure a plain text diff is sufficient to know that nothing at all has changed about federal communication laws since this section was last amended in 2002. But if you want to know what the actual law is, you definitely need more than just a text diff.

That seems like a great way to turn functional legislation into swiss cheese as one line at a time things are either kept or removed based on chance/circumstance and the whims of the current people in power.
Laws are collectively voted for as a complete package, and a law that worked and was passed as being acceptable can become useless, dangerous, and undesirable with a very small number of lines removed from them. I want lawmakers to spend their time focused on the entirety of a bill. Your idea would result in them fighting over who should or shouldn't be recorded as the official author of each and every line. We don't need nonsense like "Senator X will retire soon so Senator Y should author it!", or "I'll agree to author line 405 if you agree to author line 30!"
Your idea, like so many ideas where laws just fade away unless something happens to keep them, also sounds like a great way for you to lose longstanding freedoms and protections that should never be at risk of simply deprecating just because some one gets voted out or dies or retires.
The intent of a law should be clear from the text. It isn't always, but at least now it's possible. To have the intent of a law, or even worse the intent of specific lines within a law, subject to change at any time would make interrupting that law and establishing precedent a nightmare for the courts.
We really should have a system in place to help clear out old and unnecessary laws on the books, but this would be a terrible way to accomplish that.

I wonder if there are any public sources for any of this data at a federal level? And do any of them still hold the older now versions?
The tl;dr is that doing git-style change-tracking of the legislation isn't as helpful in practice as you'd think (especially because a lot of the very basic change-tracking is already available in the existing tools that lawyers use!).

I put a lot of thought into this last decade, I find that some bills are big blocks of new text, and other bills are convoluted instructions to modify other blocks of existing law, sometimes saying "strike this word and that word" other times referencing just a subsection of another law. hyperlinks to that other law or a model of what the legal code would look like is necessary

There's actually two kinds of changes here: changes to the law, and changes to your description of the-law-and-its-changes (metachanges). For example, if you make a mistake in recording a change to the law, you need to fix that (unlike eg a source repo where mistakes in a commit message are forever).
So to make this a git repo, I guess you'd make the snapshots be the law plus markup for all the changes, and the diffs are the metachanges. For each snapshot S, you could generate a git repo whose snapshots are the law and the whose diffs are the changes in the law (as described by S). However, this probably isn't the best way to query S.

The legislative process is inherently collaborative in a way that's ordinarily undocumented. Who introduced an amendment and who supported it are entirely separate. Someone who introduced language can wind up not supporting it because of where the mix of trade-offs winds up.
At the level of a bill, knowing who wrote language matters. At the level of law, you should only care who voted for it. (I'm not even tackling the inherent subjectivity in tracing e.g. language in the CFR to specific language in a bill.)

"... Think of what version control software could mean for the Congress [...]. If bills were created under a system where strike-throughs and additions were carefully tracked, the public would know which legislator made which change to a proposed piece of legislation as it made its way through the Capitol.
At last, there would be transparency in the legislative process. Best-case scenario, it would shame legislators from inserting language against the public interest and only meant to reward political contributors; at worst, it would make such insertions public and allow the voters to punish the politicians who made them. ..."
(from https://www.nytimes.com/2007/07/23/business/media/23link.htm... )
I do think there are some Markdown-based open source projects that might fit the bill.
Insert language you know will never get enough votes
Don’t strike out but add language to make it useless
Plus the bill sponsor often makes changes others ask for, so the true author isn’t noted
It would be a mess and ignored by the public after a while
This is often especially cynical because [popular thing x] is often something that neither party wants to pass. So a very recent example of this was an act against insider trading by politicians, that was bundled with a voter id law. Neither side wants to clamp down on insider trading from politicians, so the entire act was DOA. It was nothing but bread and circuses.
Our problem is that the press isn’t doing their job, not that legislation doesn’t have a commit graph. The latter, even if it existed, would not fix the former.
However you are proposing that journalists as a homogenous group do some extra work. I think that's a great thing but I don't get why you say the press aren't doing their job when they are at an historical low of compensation and respect.
If sounds like you are outsourcing your rage at the legislature and the press and journalists are the problem?
Sticking to the FTA someone made a first step in version tracking legislative texts but you do not think they've done enough?
In the present day, mainstream journalists won't be meaningful advocates for democracy and the public interest any time soon. It's time to acknowledge that this idea is wishful thinking. The root cause is changes to the law like the Telecom Act of 1996 which allowed for the consolidation of old media under a few corporations.
For many years these mainstream journalists have been required to support corruption, cronyism, the centralization of power, and the increase of corporate power in order to retain their jobs. The law needs to be changed before they can become a net benefit to society again.
I'd actually argue that this is the wrong way around. Being able to git diff legislation is very good, but mainly for humans, who need tools to make work tractable.
An agent will use whatever interface is available, including no interference, won't give up due to the task being too onerous, and can be scaled by paying for more tokens. It could simply brute force diff the raw text, writing bespoke Python and regexes, etc.
LLMs make brute forcing intellect possible. It's humans who need finely crafted tools.
Well, it's practically impossible to get a person to do something when their paycheck depends on their not doing it.
The problem is, barely anyone is willing to pay the press for doing this job.
Outrage farming and clickbait make money, honest reporting does not.
Of course a tool itself doesn't solve the problem. You need somebody to use the tool. But the tool makes it easier to solve the problem.
You’d just got a system of favors for who inserts what language. You’d hand tough edits to your safe-seat colleagues and insert messaging amendments designed to get voted down for own comms.
When a measure becomes a target yada yada.
(Note: this proposal is for the U.S. code. Not bills. Git for the USC works.)
The House Office of the Legislative Counsel is non-partisan, impartial, and confidential. Whether transparency has merit or not, tracking provenance would make the office partisan. Is more partisanship in government not a concern?
The second issue with transparency is that communication between legislators and legislative counsel member is subject to the attorney-client relationship. Breaking attorney-client privilege is a serious decision. Knowing how such a change would affect the organization and its members is not something to be taken lightly.
A more convincing argument for transparency would address impartiality and confidentiality. This is pretty clearly a Chesterton's fence type situation where advocating to change a system should anticipate criticisms. Addressing opposition preemptively is an implicit demonstration of knowing why the system exists which is table stakes for changing it.

Tracking who added what language is in no way partisan.

Actual bills are written in the form of patches ("§1. In the law X paragraph 5, the words "such and such" are replaced with "this and that". §2. The law X paragraph 4 is striked. §3. After law X paragraph 8, a new paragraph 8a is added that says "etc. and so on".)
After a patch or a collection of patches are passed, they are combined together and a unified version of the law is published. These documents aren't technically the law, they just show a snapshot of what the law is at the specific moment.
ISAP system is an online collection of all bills that were passed, plus crosslinks between laws that change/supercede/otherwise interact with each other, plus current and archival unified versions, plus related administrative orders and other miscellanious documents. Makes looking up laws and changes to laws very easy.
Example page for the traffic code https://isap.sejm.gov.pl/isap.nsf/DocDetails.xsp?id=WDU19970...
First PDF is the original, second PDF is the unified version, then there's links - 4 others changed, 4 explicitly obsoleted, 12 implicitly obsolete, 707 administrative orders, 12 Constitutional Tribunal rulings, 11 previous + current unified versions, 212 patches, 14 relevant EU directives.
In Australia, I spent a bit of time trying to work out how to find which politician voted for what (both at state and federal level), so that when elections come, you can single out the individuals who voted for what legislation. I think AI may make this easier, but the challenge is in not spamming the "free and open" access to the online record of our legislation.
So far, it's probably a one-person $50K per year job to do this task manually, and the language of the public legislation record didn't lend itself easily to determining the laws or rights that actually changed when bills were passed into legislation. They are explicitly stated, but hard to distill with regexes, filters or other analysis tools (e.g. "Who voted to stop electric scooters going over 25km/h?") If you try reading the legislation, you will know what I mean.
"A complete and open record of the proceedings of our parliament" still needs people spend a good chunk of time interpreting and summarising it (e.g. the media, commentators, etc) which means it's a time-consuming hobby or a paid gig.

That's an interesting project - I am guessing it's only targeting federal level, but could also include state level
The first problem I have in my mind is proxy votes, and votes that are made mandatory by the party they belong to - eg. a backbencher would struggle to go against the wishes of their party unless they felt it was worth risking their career over

The idea is cool though.
As an aside, my city FB group(small town, basically the local forum and news) has been absolutely flooded with AI 'flyers', and I have the same reaction. I can't put my finger on the exact reason, maybe the busy-ness, but they're repelling to my eyes.
Luckily after about 6 months of this now they're starting to get heavy pushback.
Blew my mind when I realized I could do that.
Now major version coming within 1 month probably with many architectural changes. The thesis is that it's basically all doable as a compiler but there may be certain cases which are irreducibly ambiguous and need human/AI to adjudicate them. The rest must be deterministic.

Version control for the public parts will make both public and secretive law-drafting better.
If you have a problem with your representative’s behavior, call their office and ask about it. They will certainly have a reason. Tell them if you disagree, and vote when you can.
Only if those bold reforms weren't in the interests of the people they serve. Risky bipartisan compromises should still be transparent along with what was gained in exchange for them. If the people feel that the compromise wasn't worth it they should be empowered to vote accordingly come election time. It's the job of representatives to assure the people who elected them that they are doing a good job and if they can't do that they deserve to lose their position. Refusing to support bold reforms that the people they represent want, or refusing to compromise when it would be beneficial to voters would become just as costly to their career.
> It takes significant work to produce successful legislation, and much of that work can be productively and safely done without direct public oversight.
Often most of that work is done entirely for them by corporations and lobbying groups and "law makers" just vote how they are paid to vote without even reading the bill put before them. Just because something can be done in secrecy doesn't make that the ideal way to do it. We've have extremely poor results with the system as it stands right now, so a change to introduce more transparency and accountability seems like a very good idea.
> This is the same reason an individual might value a private journal.
A public servant representing the people by making edits to laws and performing the duties they were elected to carry out is nothing at all like someone keeping a private journal. Their work is not their personal affairs, it is the public's affairs. How that work is being done matters to the public. Legislators would still remain free to go home at the end of the day and write in their private diary all they like.
> If you have a problem with your representative’s behavior, call their office and ask about it.
When their behavior is conducted in secrecy behind closed doors the public doesn't have the ability to hold them accountable for it, which is exactly why it takes place in secrecy. Increasing the public's ability to hold elected officials accountable by increasing transparency can only improve outcomes for voters, and it would certainty be inconvenient for elected officials who want to put their own interests above the interests of the people who elected them.
A surprising amount of tracking and diffing in legal texts is actually very different to git. It's a trap to assume software version control fits the needs for legal work.
For the record, and feel free to steal it if you like it, I called it “G(overnm)it-blame”
I thought legal document versioning software would cover some of these problems but it doesn't seem like a similar enough process.
I'm not saying lawyers aren't really really expensive, but you don't have to spend a long time digging into just a simple question like "what parts of the law are no longer enforceable after a supreme court decision" before you start to understand why they charge the prices they do.
Someone set it up for Philly and Baltimore too, but I can't seem to find it.
Does it already exist?
Thing which are public law should be publicly accessible.
There's an online portal for NEC code book, but they made it awful, no search, no hyper links, the bare minimum.
I used codex in computer mode to collect the relevant pages to my project. (Electricity to shed).
Also, because how the judicial branch decides case law needs to be reviewable by the People, so that we can inform the various legislatures to adjust the law if the judicial system is not ruling to the will of the People.
In the interpretation of the law, yes, but that doesn't matter for version controlling the text of the law, and in that sense, you can absolutely manage the text pretty cleanly in git. Most laws are just text. Many bills are literal git-diffs, except in prose, which can make it hard to understand a bill.
> exception handling (hardcode-style responses)
This is basically non-sequitur (there no such thing as a "hardcode-style response" in git…), and again, I think you're misunderstanding the idea here.
The complexity is in common law, not natural-language laws.
The U.S. Code and Code of Federal Regulations can be completely presented through a Git-like system. The complexity comes in when attaching court cases.
If you've got a statute like "no vehicles in the park," the fundamental issue is that you have to interpret "what is meant by 'vehicle'?" and no legal drafting is going to be good enough to actually cover all the possible cases well enough. The main difference between a common law and a civil law system here is that in a common law system, you have to cite the previous similar cases (because precedent is binding) whereas in a civil law system, you're merely using those previous similar cases as persuasive evidence. At the end of the day, it boils down to arguing for your interpretation.
And in my experience working on language standardization (which is closer to a civil law system than a common law system), it's fairly often that I have to resort to looking up not just when a change in the text occurred, but dive deep into the discussions of the paper proposing the change to understand what the committee thought it was doing with the change. The complexity of law is fairly similar--the changes to the law themselves often require understanding the legislative and interpretative history of the law to understand what the intent of the drafter was to be able to rule on how the law is extended to an unanticipated scenario.
If you want to know the literal text (that may or may not be enforceable), then sure a plain text diff is sufficient to know that nothing at all has changed about federal communication laws since this section was last amended in 2002. But if you want to know what the actual law is, you definitely need more than just a text diff.
That seems like a great way to turn functional legislation into swiss cheese as one line at a time things are either kept or removed based on chance/circumstance and the whims of the current people in power.
Laws are collectively voted for as a complete package, and a law that worked and was passed as being acceptable can become useless, dangerous, and undesirable with a very small number of lines removed from them. I want lawmakers to spend their time focused on the entirety of a bill. Your idea would result in them fighting over who should or shouldn't be recorded as the official author of each and every line. We don't need nonsense like "Senator X will retire soon so Senator Y should author it!", or "I'll agree to author line 405 if you agree to author line 30!"
