E-petition threshold design

As agents can manufacture signatures at scale, a signature threshold stops standing for real collective concern and starts measuring how much support a faction can automate. The count that was meant to ration government attention toward issues that move many people becomes something an agent can pad at will.

UK Parliament e-petitions. The system runs two tiers: 10,000 signatures triggers a written Government response, and 100,000 leads the Petitions Committee to consider scheduling a debate. It has been criticized on the ground that a numerical threshold implies an issue's importance can be counted, that issues of national importance may not attract enough signatures, and that volume rewards mobilization capacity over the quality of an argument.

We the People (United States). The White House response threshold rose from 5,000 signatures to 25,000 and then to 100,000, a twentyfold increase, while the 30-day signing window stayed put. Demand rather than quality is the reason of record for the first rise: the White House attributed it to the site's opening week, with more than 7,800 petitions posted and more than 375,000 accounts created. Threshold inflation is the natural consequence of reducing friction in petition creation.

NSW Legislative Assembly petitions. Receipt is announced in the House on the next sitting day, recorded in the Votes and Proceedings, published in Hansard, and forwarded to the responsible Minister; at 500 or more signatures the Minister must respond to the Clerk within 35 calendar days, and that response is itself reported in the House. At 20,000 ePetition signatures, or 10,000 on paper, a debate is triggered. Opening an ePetition needs the support of at least five people and a Member, which places a floor before the threshold ladder starts.

Australian House of Representatives e-petitions. Two sourced instances show the volume the channel carries: e-petition EN1041 closed with 403,478 signatures and EN1938 with 501,128. The House's petition rules set the intake contract, covering subject-matter jurisdiction, an online form that enforces the rules at the point of creation, and Petitions Committee vetting before publication. The rules are enforced when the petition is written, and not after it has gathered signatures.

E-petition threshold design is directly relevant to any government intake system that uses volume as a proxy for legitimacy or priority:

• Thresholds must be dynamic, adjusting to submission volumes and the prevailing cost of generating support.
• Signature verification must be tied to verified identity, not just email addresses. The UK system requires a name, email, and postcode; AI agents could trivially generate plausible combinations.
• Quality signals should complement volume signals: geographic distribution of support, diversity of supporting arguments, or evidence of deliberation.
• Response commitments create accountability but also create an attack surface: a committed response at a threshold lets adversaries use agents to force responses on chosen topics.
