Despite Ballot Challenge Failure, Slaton v. Blackman Dispute Escalates

A Maricopa County Superior Court judge has dismissed Republican Steve Slaton’s 2026 election challenge against Arizona State Representative Walt Blackman, leaving the Legislative District 7 Republican incumbent on track for the July 21 primary ballot. The case, brought by Slaton, sought to disqualify Blackman over alleged campaign finance violations tied to an inactive campaign committee. Slaton claimed the committee had accumulated more than $168,000 in unpaid fines and late fees after years of missed reporting deadlines. However, the court never reached the substance of those claims.

On April 2, 2026, Maricopa County Superior Court Presiding Judge Scott A. Blaney dismissed the case without prejudice, citing fatal procedural defects. The court found that Slaton failed to name and properly serve all required parties, including election officials responsible for ballot preparation. Under Arizona’s expedited election challenge timeline, it was effectively too late to cure and refile. The dismissal was not a determination that Blackman complied with campaign finance law. It was a determination that the challenge itself was not legally viable in its current form.

Blackman has characterized the issue as an “administrative error” tied to the disruption of the 2020 election cycle, stating he acted in good faith and has worked to address the reporting issues with the Secretary of State’s office. The lawsuit is the latest chapter in an ongoing and increasingly personal political dispute between Blackman and Slaton. Slaton, a Show Low business owner who operates a MAGA-themed retail store, previously ran against Blackman in the 2024 Republican primary and lost.

In December 2025, Blackman filed a defamation lawsuit (Case No. S-0900-CV-202500623) against Slaton and his wife, alleging they made false and damaging statements about his military service, including claims involving a Bronze Star designation. According to the complaint, Blackman asserts the statements were knowingly false and harmed his reputation. The case remains pending. At the same time, Slaton has attempted to escalate the dispute beyond the judiciary.

In a message sent to Arizona legislative leadership  titled “Public Trust,” Slaton called for disciplinary action against Blackman, including censure, removal from committees, and enforcement of financial penalties tied to the alleged campaign finance violations. In the email, Slaton wrote that “many citizens of our State are pissed off that elected Representatives are not held accountable,” and pointed to what he claims are more than $168,000 in fines stemming from years of unfiled reports. He further urged lawmakers to act, stating they have the authority “to remove from office, censor, expel from committees, and to pay fines and penalties,” copying both Katie Hobbs and Kris Mayes. Despite those calls, no formal legislative action has been taken against Blackman as of this reporting.

The practical outcome is clear. Blackman remains on the ballot. Slaton’s legal challenge failed on procedural grounds. The campaign finance allegations remain unresolved in court. For voters in Legislative District 7, the issue now moves out of the courtroom and back into the election itself, where the final decision will be made.
