If you want to understand why people distrust the Legislature, you do not need a conspiracy. You need the action history of House Bill 2873, which is a public document and takes about four minutes to read.

The bill was introduced on January 15, 2026 with the title competitive sealed bidding, questions, answers. It was a procurement measure, requiring a mandatory question-and-answer period in the Department of Administration’s sealed bidding process. Dull and defensible. It cleared the House Government Committee 4 to 3, went through Rules, and passed the full House on February 26 by a vote of 37 to 16.

Then it went to the Senate and stopped being that bill. On March 25 the Senate Regulatory Affairs and Government Efficiency committee adopted a strike-everything amendment by a vote of 7 to 0. Everything about sealed bidding was deleted. What replaced it was a new section of election law, and the new short title was municipalities, referendum petitions, withdrawal.

Read what the replacement actually did, because the summary undersells it. The new statute let a person or organization that had filed a municipal referendum petition withdraw that petition by written notice at any time before the measure qualified for the ballot. That alone would be a significant change. The bill went further in Section 3, applying the withdrawal authority retroactively to every notice of withdrawal filed on or after December 31, 2025, regardless of whether the withdrawal was accepted or rejected, and prohibiting votes for any such referendum from being tallied or canvassed. Section 2 then repealed the whole mechanism on July 31, 2027, and Section 4 attached an emergency clause.

Set the politics aside and look at the shape of that. A retroactive window that opens on a date already past, applies over the objection of a clerk who already rejected a withdrawal, forbids counting votes that may already have been cast, and expires in nineteen months. Laws written for the general case do not have expiration dates nineteen months out. Laws written for one dispute do.

The dispute, according to Rural Arizona Action, was Marana. The Coolidge-based group says HB 2873 was backed by data center lobbyists and amended specifically to target Marana residents who had organized a referendum against a proposed data center development, and that the retroactive timeframe was designed to erase thousands of signatures residents had lawfully collected. That characterization is theirs, and we have not independently verified who lobbied for the amendment. The dates and the retroactivity are not characterization. They are in the bill text linked below.

The Senate passed it on April 21 by 20 to 9. Then it returned to the House for a final reading, and this is where the record gets genuinely unusual.

On June 11, the House rejected HB 2873. The tally was 27 in favor, 24 against, with 9 not voting, which failed because passage requires 31 votes in a 60-member chamber regardless of how many members are present. Rural Arizona Action put out a release that afternoon celebrating a major victory for Arizona voters and thanking the 24 legislators who had voted no.

The celebration lasted a few hours. Later the same legislative day, Rep. Jeff Weninger moved that the House reconsider HB 2873 and place it back under the order of business for final passage. The motion passed on a voice vote, which means there is no recorded tally of who agreed to reopen it. The bill was voted on again and passed, 31 to 27, with 2 not voting.

Four members changed their votes between the two roll calls: Junelle Cavero, Janeen Connolly, Jeff Weninger, and Khyl Powell. Weninger, who made the reconsideration motion, was among them. Cavero represents District 11 in south Phoenix, roughly ninety miles from Marana.

A reconsideration motion is a legitimate parliamentary tool and both parties use it. It exists so a chamber can correct itself, and there is nothing improper on its face about a member deciding on reflection that a first vote was wrong. But the mechanics here deserve to be stated plainly, because they are the whole point. A bill that had failed was revived on the same day it died, on an unrecorded voice vote, and carried by exactly the number of switched votes required to reach the threshold. The margin was four. The switches were four.

We reviewed the available record and did not find a public explanation from Cavero for the reversal. That is not the same as saying she declined to give one, and if she has explained it we will append it. The question a District 11 constituent is entitled to ask is simple: what changed between the morning vote and the afternoon vote on a bill that would have voided petition signatures already gathered by residents of another town.

Gov. Katie Hobbs vetoed HB 2873 on June 19. Her veto message, as summarized in the Senate fact sheet, said the bill would introduce uncertainty and confusion into ongoing litigation on the subject matter. That is a narrow and lawyerly ground, and notably it is not a defense of referendum rights as such. Marana’s referendum survived because one office holder declined to sign, not because the Legislature declined to pass it.

The lesson is not about data centers, and it is not really about Cavero, who was one of four. It is about a procedure that lets a procurement bill become an election-law bill in a single committee vote, get retrofitted with a retroactive clause aimed at a specific pending petition, die on the floor, and pass anyway before the day is out. Every step of that was in order. That is what makes it worth writing down.

Marana residents collected signatures under one set of rules and came within one veto of having them voided under another set written after the fact. Anyone who thinks local referendum power is a settled feature of Arizona law should read the June 11 action history and reconsider.
