Signature Verification and Deadlines

Gathering signatures is the part people see. Verification is the part that decides. In 2026 one statewide campaign said it gathered more than 150,000 signatures and still came up about 12,700 valid signatures short of the 70,725 it needed. Another turned in fewer and qualified. The difference was what happened at the county clerk's counter. This lesson follows a petition from the sponsor's box of sheets to the Secretary of State's final letter, then sets out the calendar for a measure aimed at the November 2028 ballot. The steps before circulation are in lesson 4, and the rules for the people carrying the clipboards are in lesson 7.

Where verification sits in the law

Four sections of Title 34, Chapter 18 carry the verification process for statewide initiatives:

• 34-1802(1) and (2), the gathering and turn-in windows. Circulation starts when the sponsors receive both the fiscal impact statement and the official ballot title and runs 18 months or until April 30 of the election year, whichever comes first. The signed petitions go to the county clerk by close of business on May 1 of the election year, or 18 months after the sponsor receives the ballot title, whichever is earlier.
• 34-1802(3), the clerk's clock. The county clerk verifies "within sixty (60) calendar days" of the submission deadline, and never later than the last day of June.
• 34-1807(4) and (5), the check and the certificate. The clerk strikes names whose name, address or signature do not match, confirms the rest belong to qualified electors of the proper jurisdiction, attaches a certificate stating how many signatures are those of qualified electors in a named legislative district, and hands the petition back to whoever turned it in.
• 34-1802(4), the final filing. Petitions "with the requisite number of signatures attached" go to the Secretary of State not less than four months before the election.

Two practical facts follow. First, the clerk certifies by legislative district, which is how the district test in the next section gets counted. Second, the sponsor carries the certified sheets to the Secretary of State. The Secretary of State's filing requirements page warns that clerks are not required to mail verified petitions back, so the sponsor has to collect them. Once filed, the Secretary of State keeps the sheets as official public records under 34-1806.

Referendums use the same verification machinery but a different deadline: verified referendum petitions must be filed with the Secretary of State not more than 60 days after the Legislature adjourns (34-1803). City, county and fire or ambulance district measures use the chapter with local substitutions, including 60 days for the county clerk to verify (34-1801B(14), 34-1801C(13) and 34-1801D(13)); lesson 6 has the local details.

Recall petitions run faster

Recall verification is in Chapter 17. All sheets must be filed on the same day with the Secretary of State or county clerk. The Secretary of State sends state-officer petitions to the county clerks, and the clerk's examination "shall not exceed fifteen (15) business days" from receipt (34-1706). If the count is short, the officer stays in office and no new recall petition may circulate against that officer for 90 days (34-1707(4)). The sponsor has only 75 days from approval of the petition's form to perfect it (34-1704(2)). Lesson 3 covers recall thresholds and the vote itself.

What the clerk checks, line by line and sheet by sheet

Some problems knock out one line. Others knock out every line on a sheet, which is why a single careless circulator can cost a campaign hundreds of signatures. The table sorts them.

Problem	Idaho Code	What it costs
Name, address or signature does not match a qualified elector of the right jurisdiction	34-1807(4)	That line
Signer lives in a different county from the one the sheet is for	34-1804(3): each sheet may contain signers from only one county	That line
Signature is not a physical signature (electronic, typed, stamped)	34-1807(7)	That line
Signer signed a name other than their own, signed twice for the same measure, or was not a legal voter	34-1814 (also a crime)	That line, and possible prosecution
Signature obtained without first showing the short and general ballot titles, or by false statements	34-1815	That line
Signer filed a written or electronic removal request before verification	34-1803B(2)	That line
More than 20 signatures on one sheet	34-1804(3)	Lines past 20 are not counted
Circulator not an Idaho resident at least 18 years old (residency as defined in 34-107)	34-1807(1) and (6)	The whole petition the circulator gathered
Paid circulator did not give the verbal notice, wear the badge or use pages carrying the payment declaration	34-1807(2) and (8)	The whole petition circulated in violation
Missing or defective circulator affidavit, or no notary	34-1807(3)	The sheet, unless the form was substantially followed (34-1807(5))
Petitions reach the clerk after close of business on the deadline	34-1802(2)	Every late sheet

Two softening rules apply. The statutory forms "are not mandatory," and if substantially followed, clerical and "merely technical" errors are disregarded (34-1807(5)). And the clerk must strike a removed name and adjust the count "immediately" when a signer asks in writing (34-1803B(2)). Where the line between a technical error and a fatal one falls is where most fights happen, as the 2026 cycle showed.

The 2026 cycle: one drive failed, one qualified

Three citizen initiatives were circulating for the November 3, 2026 ballot, according to the Secretary of State's initiatives page. The Reproductive Freedom and Privacy Act qualified. The Idaho Medical Cannabis Act and the Decriminalize Cannabis Now initiative did not submit enough valid signatures, either in total or across districts.

The medical cannabis petition

The sponsor, the Natural Medicine Alliance of Idaho, said it gathered more than 150,000 signatures. County clerks certified at most 58,024, against a requirement of 70,725, and the measure met the district test in 13 districts, not 18, according to the Idaho Capital Sun's July 14, 2026 report on Secretary of State Phil McGrane's letter. Cannabis Business Times computed the loss as a 61 percent disqualification rate. The problems the office and the sponsor described line up with the table above:

• Circulator residency. The office could not verify residency for 293 people who circulated petitions. Under 34-1807(6), every sheet those circulators gathered is void if residency fails.
• Possible fraud. One petition listed a voter whom state records show died in 2021, and similar handwriting and voter information led the office to refer complaints to the Idaho State Police. McGrane's letter added that "a referral is not a finding of criminal liability."
• Wrong county, missing dates, inactive voters and payment disclosures. The sponsor's July 17 response, as reported, objected that counties rejected signers who used another county's sheet, thousands of undated lines, and thousands of voters listed as not active. The office's final letter also cited insufficient circulator documentation and payment disclosures.
• A late box. A contractor arrived at the Minidoka County clerk's office with nearly 900 signatures after close of business on May 1. Security footage showed arrival around 5:05 p.m. The sponsor sued to force the count, and on June 18, 2026, District Judge W. Reed Cotten ruled the signatures came too late, the Capital Sun reported.

The sponsor blamed its first signature-gathering vendor and said it would not take the statewide disqualification to court.

The Reproductive Freedom and Privacy Act petition

The sponsor, Idahoans United for Women and Families, turned in petitions carrying more than 110,000 signatures, which its press release called more than 1.5 times the requirement, the Capital Sun reported. The Secretary of State's July 14 press release listed 75,478 signatures across 20 legislative districts and certified the measure, which appears on the ballot as Proposition 1. County clerks did the first check and the Secretary of State's office did the final review. The release did not state a validity rate, and the two published figures may not measure the same stage, so treat any rate computed from them as a rough indicator only.

The contrast is the lesson. A cushion of raw signatures matters less than whether each sheet survives the sheet-level rules. The drive that reported more raw signatures finished about 17,000 valid signatures behind the one that qualified.

The district test, and the statute that says something else

The Secretary of State applies two tests. Valid signatures must equal 6 percent of registered voters at the last general election statewide, and 6 percent of registered voters in at least 18 of the 35 legislative districts. The 2024 general election canvass lists 1,178,750 registered voters statewide. Six percent of 1,178,750 is 70,725, the 2026 figure Ballotpedia and the Secretary of State reported.

Read 34-1805(2) today and it says 6 percent "in each of the thirty-five (35) legislative districts." That text came from Senate Bill 1110 in 2021. In Reclaim Idaho v. Denney (August 23, 2021), the Idaho Supreme Court held that version unconstitutional and restored the earlier rule of 6 percent in at least 18 districts plus the statewide 6 percent. The section's history line shows no amendment since, so the code still prints language the court has voided. Anyone checking a petition's sufficiency should work from the Secretary of State's stated rule and the court decision, and treat the printed 35-district language as a trap. Lesson 10 covers the case.

The base number moves every two years. For a 2028 measure, the statewide and district thresholds will be set from registration at the November 3, 2026 general election, which the Secretary of State will publish after the 2026 canvass. A sponsor planning a 2028 drive cannot know the exact target until then, which is one more reason to plan with a margin.

How sponsors track their own numbers

Sponsors cannot see the clerk's work until it is done, so serious campaigns run a shadow count. The basics:

• Log every sheet. A sheet number, county, circulator name, whether the circulator is paid, date range and line count. If a circulator's residency is later questioned, the log shows exactly which sheets are at risk under 34-1807(6).
• Sample, do not guess. Check random lines against registration records, by county. The useful number is valid lines divided by lines checked.
• Track by district, not only statewide. The statewide total is rarely the binding test. The 2026 medical cannabis drive missed both, but it was five districts short of 18.
• Turn in early. McGrane told the medical cannabis sponsor to submit earlier than the deadline, the Capital Sun reported. Early turn-in gives the clerk room and gives the sponsor time to learn about problems while circulation is still open.

Challenging a count, a refusal or a title

The law gives specific, short routes.

• A refusal to file. If the Secretary of State refuses a petition that has enough signatures, any citizen may apply to the district court for a writ of mandamus within 10 days of the refusal. The court files it as of the original date if it is legally sufficient, and either side may appeal to the Supreme Court within 10 days of the decision. The Fourth District Court in Ada County handles statewide measures (34-1808). The same section lets a court bar a legally insufficient petition from the ballot.
• A recall refusal. 34-1715 gives 10 business days to seek mandamus, appeal to the Court of Appeals within 10 business days, and Ada County jurisdiction for state officers. If the court orders the petition accepted, the 75-day clock restarts from the judgment.
• A clerk's rejection of specific lines. In January 2021, recall supporters sued the Bonneville County clerk over nine rejected signatures on a recall petition against an Idaho Falls School District 91 trustee, seeking mandamus. A district judge ruled for them on February 22, 2021, finding the recall qualified, Ballotpedia reported. Before the ruling, the clerk's count had left the petition four signatures short of the 481 required, East Idaho News reported on January 30, 2021.
• A ballot title. Anyone dissatisfied with the Attorney General's short or long title may petition the Idaho Supreme Court within 20 days after the title is filed with the Secretary of State (34-1809(3)). That is a calendar item for opponents as much as sponsors: the window opens before a single signature is gathered.
• Constitutionality. Any qualified elector may ask the Supreme Court to rule on an initiative's constitutionality any time after the certificate of review (34-1809(4)).
• Fraud claims about signatures. In 2024 the Supreme Court said such claims must start in district court; see lesson 10.

The calendar for a 2028 statewide initiative

The general election falls on November 7, 2028. Working back and forward from the statutes gives this calendar. Dates tied to "not less than" or "within" language are approximate where a weekend intervenes; confirm each with the Secretary of State.

One printed rule needs a warning label. 34-1813(2)(a) says a statewide initiative may take effect no earlier than July 1 of the following year. The court summary in Reclaim Idaho v. Denney reports that the court unanimously held that 2020 provision unconstitutional, as an intrusion on the people's power to enact laws independent of the Legislature. The text is still in the code. A sponsor who wants a clear answer can write an effective date into the measure itself.

The 2026 Reproductive Freedom and Privacy Act shows the back half of the calendar in real dates: certification announced July 14 (the Capital Sun reported qualification on July 13), the argument window closing at 11:59 p.m. on July 31, and an Idaho Supreme Court fight over the yes and no statements decided September 4 to 6, after the voters' pamphlet had already gone to the printer.
