The Idaho Constitution is the state’s supreme legal document, adopted in 1889 and in force since Idaho joined the Union on July 3, 1890.1Idaho State Historical Society. Constitutional Convention and Ratification It ranks just below the U.S. Constitution in legal authority within the state. The document does four main things: it organizes state government into three branches, protects individual rights, requires the legislature to fund public schools, and sets a deliberately high bar for its own amendment.
Rights Idahoans Have Under the State Constitution
Article I is Idaho’s Declaration of Rights. Many of its guarantees mirror the federal Bill of Rights, but several go further or address issues rooted in Idaho’s own history.
Firearms
Section 11 protects the right to keep and bear arms and expressly bars any law imposing licensing, registration, or special taxation on firearm or ammunition ownership. The only firearms the state can confiscate are those actually used in committing a felony.2Justia. Idaho Constitution Article I, Section 11 – Right to Keep and Bear Arms That is a notably more detailed protection than the Second Amendment itself.
Religious Liberty
Section 4 guarantees free exercise of religion and bars the state from denying anyone civil or political rights based on belief. No one can be forced to attend, support, or pay tithes to any church. The same section, reflecting conditions placed on Idaho’s statehood in the late 1800s, “forever” prohibits bigamy and polygamy and forbids counseling or advising others to commit those offenses.3Justia. Idaho Constitution Article I, Section 4 – Guaranty of Religious Liberty That language remains in the document today.
Criminal Justice
Section 7 preserves the right to a jury trial in civil and criminal cases, with specific rules allowing less-than-unanimous verdicts in civil and misdemeanor cases.4Justia. Idaho Constitution Article I, Section 7 – Right to Trial by Jury Section 6 bars excessive bail, excessive fines, and cruel and unusual punishment.5Justia. Idaho Constitution Article I, Section 6 – Right to Bail, Cruel and Unusual Punishments
Crime Victims
Section 22, added later by amendment, gives crime victims a set of rights that run through the criminal process: fair and dignified treatment, timely case updates, attendance at proceedings, communication with prosecutors, the chance to be heard at sentencing and parole hearings, restitution from the offender, and the right to refuse interviews or contact from the defendant.6Justia. Idaho Constitution Article I, Section 22 – Rights of Crime Victims These rights are self-executing, meaning they take effect without further legislation, though lawmakers can expand them.
How State Government Is Structured
Article II divides state government into three branches and forbids anyone in one branch from exercising powers belonging to another, except where the constitution itself allows it.7Justia. Idaho Constitution Article II, Section 1 – Departments of Government That principle shapes the three articles that follow.
Legislature
Article III vests lawmaking power in a Senate and House. The constitution calls for between thirty and thirty-five senators and allows the House up to twice as many members.8Justia. Idaho Constitution Article III, Section 2 – Membership of House and Senate Idaho currently seats thirty-five senators and seventy representatives, each serving a two-year term. To run, a candidate must be a U.S. citizen, a registered Idaho voter at the time of election, and a voter in the specific county or district for at least a year before election day.9Justia. Idaho Constitution Article III, Section 6 – Qualifications of Members The constitution sets no minimum age beyond the voting age of eighteen.
Executive
Article IV creates seven elected statewide offices: governor, lieutenant governor, secretary of state, state controller, state treasurer, attorney general, and superintendent of public instruction. Each serves a four-year term starting the first Monday in January after the election, must live in Idaho, and must keep offices at the seat of government.10Justia. Idaho Constitution Article IV, Section 1 – Executive Officers Listed, Term of Office The governor leads the branch and is responsible for enforcing state law.
Judiciary
Article V establishes the court system. Supreme Court justices are elected statewide to six-year terms.11Justia. Idaho Constitution Article V, Section 6 – Supreme Court, Number of Justices, Term of Office District court judges serve four years.12Justia. Idaho Constitution Article V, Section 11 – District Courts, Judges and Terms When a judge leaves mid-term, the Idaho Judicial Council screens applicants and sends nominees to the governor, who appoints a replacement; that judge then has to face voters at the next general election. The design tries to keep partisan politics out of judicial selection while preserving public accountability.
Powers Voters Hold Directly
The Idaho Constitution reserves three tools that let voters act on their own, without going through elected officials.
The initiative lets Idahoans propose new laws and enact them at the polls. The referendum lets voters force a public vote on a law the legislature has already passed.13Justia. Idaho Constitution Article III, Section 1 – Legislative Power, Enacting Clause Qualifying either for the ballot takes signatures from six percent of Idaho’s registered voters, and those signatures must be spread across at least eighteen legislative districts, with at least six percent coming from each qualifying district.14VoteIdaho.Gov. Initiatives and Amendments The geographic rule prevents a single population center from pushing a measure onto the ballot alone.
The recall under Article VI, Section 6 lets voters remove any public officer in Idaho except judges. The constitution leaves the mechanics to the legislature rather than spelling them out.15Justia. Idaho Constitution Article VI, Section 6 – Recall of Officers Authorized Judges are excluded for the same reason the state uses appointment-plus-retention for mid-term vacancies: to shield courts from short-term political pressure.
To vote at all, a person must be at least eighteen, a U.S. citizen, a resident of the state and county where they vote for the period set by law, and registered.16Justia. Idaho Constitution Article VI, Section 2 – Qualifications of Electors The constitution guarantees an “absolutely secret ballot” and tells the legislature to enforce that guarantee.17Justia. Idaho Constitution Article VI, Section 1 A felony conviction costs a person the right to vote, serve on a jury, or hold civil office until citizenship rights are restored, and anyone confined in prison on a conviction at the time of an election cannot vote.
Public Schools and Endowment Lands
Article IX gives the legislature one of its most specific duties: establish and maintain a “general, uniform and thorough system of public, free common schools.”18Justia. Idaho Constitution Article IX, Section 1 – Legislature to Establish System of Free Schools The framers tied the obligation directly to self-governance, saying the stability of a republican government depends mainly on the intelligence of the people. Idaho courts have used this clause to evaluate whether the legislature is adequately funding schools.
To fund that duty, the constitution creates the State Board of Land Commissioners, made up of the governor, superintendent of public instruction, secretary of state, attorney general, and state controller.19Justia. Idaho Constitution Article IX, Section 7 – State Board of Land Commissioners The board manages roughly 2.4 million acres of endowment land the federal government granted Idaho at statehood. Revenue from timber sales, grazing leases, and mineral rights flows into a permanent endowment fund whose earnings support public schools and other state institutions.
Limits on Taxing and Borrowing
Articles VII and VIII put strict limits on state finance. Article VII requires property taxation to be uniform and sets categories for exempt public property. Article VIII restricts debt: the legislature cannot create debt or financial liabilities except to respond to war, invasion, or insurrection, unless a specific law authorizes borrowing for a single, named project.20FindLaw. Idaho Constitution Art VIII, Section 1 – Limitation on Public Indebtedness
Even then, the law has to identify dedicated revenue (other than more borrowing) to cover interest and pay off principal within twenty years, and it cannot take effect until a majority of voters approve it at a general election. Ordinary operating expenses and debts repaid within the same fiscal year are exempt.20FindLaw. Idaho Constitution Art VIII, Section 1 – Limitation on Public Indebtedness Significant long-term borrowing in Idaho goes to the voters.
How the Constitution Gets Amended
Article XX offers two routes to change the document, and both are demanding.
The usual route starts in the legislature. A proposed amendment needs a two-thirds vote in both the Senate and the House. If it clears that bar, it goes on the ballot at the next general election, where a simple majority ratifies it.21Idaho Secretary of State. Idaho Constitution When several amendments appear at the same election, each must be presented and voted on separately so voters can accept some and reject others.
The second route is a full constitutional convention. Two-thirds of the members elected to each chamber must recommend a convention to voters at the next general election. If a majority of all voters at that election approve the idea, the legislature must provide for calling the convention at its next session. A convention must include at least twice as many delegates as the larger legislative chamber, which works out to a minimum of 140 delegates given the current seventy-member House.22Justia. Idaho Constitution Article XX, Section 3 – Revision or Amendment by Convention Any revisions a convention produces still have to be ratified by voters. Idaho has never used this method since the original 1889 convention.
