Same. I don't know if it's the word choices or just me recognizing it as AI and subconsciously feeling cheated.
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.
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

The Hacker News Community (hah) needs to lobby hard to pass a law (what boostrapping!) to require the https://en.wikipedia.org/wiki/Office_of_the_Law_Revision_Cou... to maintain the repo as part of their duties, and do it retroactively for the entire history of the US Code.
It's a simple idea; it's cheap; there are no outstanding technical questions; it benefits almost everyone. Let's get this done.

The US government works for the people and, as such, changes made to the US Code over time must be traceable, discoverable, and therefore justifiable by or condemnable to those who are responsible for said changes without fear or favor.
If you're like me and also eager for cool uses for git, I'll share a cool one I use -- try out git for your resume! Commits change as you progress in life, and make branches for individually tailored resumes.
I love this, and I feel every legal document (of which there are many, for example, a random one: insurance companies' policies) should have something like this (and no, Word is not good for it)
I had this idea over 10 years ago but never finished it. I hope this takes off. I do fear it's not very practical for many big pieces of legislation which are often written in secret.
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.
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.
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.
Wow! This is very cool. I had an idea for something very similar to this when I found out the US federal government offered API keys, maybe three or four years ago. I found that while Congress did list bill revisions as they were made the format and retrieval of these was not an easy task. The idea was that I wanted to look at any line of any bill and see who proposed it that particular line’s inclusion.
For the record, and feel free to steal it if you like it, I called it “G(overnm)it-blame”
Cool idea but I can't find anywhere on the linked page to try it? It reads like a neat concept but it's not clear if this is a thing they've actually made or not (or am I just missing something super obvious?)
I'm not an expert in this domain but I'm aware there has been prior work to attempt this. I'd appreciate if someone knowledgeable could post some of that context.
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.
I wanted to do something like this for a single section in Washington law, to show why a particular funding restriction had been added, but was no longer achieving the intended goal. Git alone wasn't enough of a UI, because the 'why' was only in the introductory text of the bill that changed the law, and not in the law itself - and then there was the move of that article to a different section, and a re-numbering of sections, and a change in definition in a different section that affected the scope of this one... fascinating stuff!
I thought legal document versioning software would cover some of these problems but it doesn't seem like a similar enough process.
Unlike code, natural language laws have many exceptions and context dependencies, so trying to manage them cleanly with Git seems like it would be tough as data structuring costs and exception handling (hardcode-style responses) increase.
This brings us to my even more unlikely idea - when whoever wrote that line in the legislation dies or retires, the line enters a short review period where it's either renewed with a new author on the line to speak to it or is deprecated. This way someone would always be there to just answer for the intent. Also would help garbage collect legislation that is no longer useful.
> Unlike code, natural language laws have many exceptions and context dependencies,
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.
> natural language laws have many exceptions and context dependencies
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.
Yeah but none of this matters for the "git for legislation" idea right? The point here is to record the history of the text of the laws, not their meaning.
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.
I see. The laws are completely different from my country, so this is very educational. My country uses civil law, but I see that is how it is under common law. Thank you very much.
YES PLEASE, but I suspect it will degenerate into another paid service with 1000 tiers... I think you cannot access the US law without paying for it? odd... I will wait for claude law to appear and hope they share the torrent...
Yes, it should absolutely change (both should be freely available), since ignorance of the law is not a defense, and case law is law (here, in the US, since we're a common law country). But the flip side of that is that the law has to be knowable, if ignorance is not a defense, or you're just going "lol too bad for you for not knowing the secret law".
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.
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
Agentically this could be done now, but it would still just be the tip of the iceberg
You're looking at quantum states of law and regulations, and that's just for one jurisdiction
Without 64-bit time though, can't use it historically. Since current legislation is always changes built upon legislation from long before unix epoch, it kind of falls flat.
Sounds neat, but not something a private company should be responsible for.
If transparency is the goal, the entire codebase for this should be public domain and not profitable. Otherwise there's a profit motive to rewrite history.
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.
Not really. It is arguing for version controlled legislation. So who’s responsible for what portions of literal laws and policy. I hope your "not clone-able" is in jest
That’s like saying that the code in a repo belongs to the whole team once a PR is merged, so it doesn’t make sense to track its provenance back to its original authors.
> so it doesn’t make sense to track its provenance back to its original authors
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.)
