Idaho's Declaration of Rights

You'll be able to

  • Compare each section of Article I with its closest federal counterpart
  • Explain how the Idaho Supreme Court has read Article I, Section 17 more broadly than the Fourth Amendment
  • Describe the 1889 history test the court applied in Planned Parenthood Great Northwest v. State
  • Identify what the 1978, 1994 and 2012 amendments to Article I do and do not do

Start here: the short version

  • Article I of the Idaho Constitution, the Declaration of Rights, has 23 sections. Twenty-one came from the 1889 convention; crime victims' rights (Section 22, 1994) and the rights to hunt, fish and trap (Section 23, 2012) were added later by voters.
  • Many sections track the federal Bill of Rights, but the wording is often different, and the Idaho Supreme Court reads some of them independently. A right can be stronger under Idaho's constitution than under the U.S. Constitution.
  • The clearest example is search and seizure. Under Article I, Section 17, Idaho courts have refused to adopt the federal "good faith" exception (State v. Guzman, 1992) and have barred warrantless arrests for misdemeanors committed outside an officer's presence (State v. Clarke, 2019).
  • Idaho's gun rights section (Section 11) was rewritten in 1978 and now bans licensing, registration and special taxes on firearms.
  • In 2023 the Idaho Supreme Court ruled 3 to 2 that Article I, Section 1 does not protect a right to abortion, because no such right was "deeply rooted" in Idaho history at statehood. That method of reading the constitution matters far beyond abortion.

When people talk about their rights, they usually mean the federal Bill of Rights: free speech, the right to bear arms, protection from unreasonable searches. Those apply in Idaho. Since the Fourteenth Amendment, most of the Bill of Rights binds state and local governments as well as the federal government. But Idahoans have a second set of rights, written in Boise in 1889, and it does not always say the same thing.

This matters in practice. A federal court decision sets the minimum protection every American has. Idaho's constitution can add protection on top of that floor. When the Idaho Supreme Court decides that the state constitution gives more protection than the federal one, that decision is final on the state-law question, and the U.S. Supreme Court generally has no power to overrule it. This lesson walks through Article I section by section, with the real cases that show how it works.

Article I at a glance

Here are all 23 sections, using the headings on the official text, with the closest federal counterpart where there is one. The site's course on the Fourth through Eighth Amendments covers the federal side.

Compare the 1889 engrossed text in Volume 2 of the convention Proceedings and Debates and you will see that the original Article I ended at Section 21. Several sections, including 7, 11 and 20, have since been amended; compare them with the current text and you will see the changes.

Sections 1, 2 and 21: where rights come from

The federal Constitution has no general statement of natural rights. Idaho's opens with one:

"All men are by nature free and equal, and have certain inalienable rights, among which are enjoying and defending life and liberty; acquiring, possessing and protecting property; pursuing happiness and securing safety."Idaho Const. art. I, sec. 1

That language is unchanged from 1889. Section 2 adds that "all political power is inherent in the people" and that they may "alter, reform or abolish" government "whenever they may deem it necessary." Section 21, like the federal Ninth Amendment, says the list of rights "shall not be construed to impair or deny other rights retained by the people."

Those broad words raise an obvious question: do they protect rights that are not named anywhere in the constitution? The Idaho Supreme Court answered that question, at least in part, in one of the most important state constitutional cases in decades.

Example: Planned Parenthood Great Northwest v. State (2023)

After the U.S. Supreme Court overruled Roe v. Wade in 2022, Idaho's near-total abortion ban, a six-week ban and a law letting family members sue abortion providers were set to take effect. Planned Parenthood Great Northwest and other petitioners asked the Idaho Supreme Court to strike them down under the state constitution, arguing chiefly that the "inalienable rights" in Article I, Section 1, including "enjoying and defending life and liberty," "pursuing happiness" and "securing safety," include a right to decide whether to end a pregnancy.

On January 5, 2023, the court rejected the challenge 3 to 2 in Planned Parenthood Great Northwest v. State, 171 Idaho 374, 522 P.3d 1132 (2023). Justice Robyn Brody wrote for the majority, joined by Chief Justice Richard Bevan and Justice Gregory Moeller. The court agreed that Section 1 is the textual home of unnamed fundamental rights. But it held that the framers meant it to protect rights as they were understood in 1889, and that a claimed right qualifies only if it was "deeply rooted" in Idaho's history and traditions at statehood. Looking at that history, the majority pointed to the first territorial legislature's 1864 law making abortion a crime, carried forward through later codes, and concluded that abortion had been "viewed as an immoral act and treated as a crime." Because no fundamental right was involved, the laws needed only a rational basis, and they passed.

"We cannot read a fundamental right to abortion into the text of the Idaho Constitution," Brody wrote, according to the Idaho Capital Sun. The court stressed that it was deciding only that the constitution "as it currently stands, does not include a fundamental right to abortion," and said voters could take up the issue through elections or amendments. Justices John Stegner and Colleen Zahn dissented. Zahn argued that a pregnant woman's inalienable rights to life and safety include a fundamental right to an abortion.

The politics did not end there. A citizen initiative, the Reproductive Freedom and Privacy Act, qualified for the November 3, 2026 ballot, according to the Idaho Capital Sun. The Secretary of State certified it on July 13, 2026, and it appears on the ballot as Proposition 1, as the Idaho Supreme Court recounted in a September 2026 ballot-statement ruling (Lesson 4). It would change state law, not the constitution, because Idaho citizens can initiate statutes but not constitutional amendments (Lesson 2).

Why this case matters beyond abortion: the "deeply rooted in 1889" test now governs any claim that Section 1 protects an unnamed right. Anyone arguing for such a right in an Idaho court has to bring history from the territorial and statehood era.

Section 4: religious liberty, with a 19th-century twist

Article I, Section 4 guarantees "the exercise and enjoyment of religious faith and worship," forbids denying anyone a civil or political right "on account of his religious opinions," bars compulsory support of any church and forbids any legal "preference" for a denomination. So far, it reads like a more detailed First Amendment.

Then it adds language found in no federal text. The liberty of conscience may not be read to "justify polygamous or other pernicious practices," or to let any organization "aid or abet, counsel or advise any person to commit the crime of bigamy or polygamy." The section ends: "Bigamy and polygamy are forever prohibited in the state." This was written in 1889, at the same time as the voting ban on Latter-day Saints discussed in Lesson 1. That voting ban stayed in Article VI until 1982; the polygamy language in Section 4 remains.

Religion and schools are addressed separately in Article IX, Section 5, covered in Lesson 7.

Sections 9 and 10: speech and assembly

The First Amendment is phrased as a command to government: "Congress shall make no law... abridging the freedom of speech." Idaho's Section 9 is phrased as a personal right with a built-in limit: "Every person may freely speak, write and publish on all subjects, being responsible for the abuse of that liberty." The "responsible for the abuse" clause reflects the 19th-century view that speakers could still be held liable for things like libel.

Section 10 protects the right "to assemble in a peaceable manner, to consult for their common good; to instruct their representatives, and to petition the legislature for the redress of grievances." The phrase "instruct their representatives" has no federal twin. The founders expected citizens to tell legislators what to do.

Section 11: the right to keep and bear arms

Idaho's gun rights section has been rewritten more dramatically than almost any other part of Article I. The 1889 version, in the engrossed text, was one sentence:

"The people have the right to bear arms for their security and defense; but the legislature shall regulate the exercise of this right by law."Idaho Const. art. I, sec. 11 (1889), Proceedings and Debates, Vol. 2, Appendix A

In 1978 the section was amended. An Idaho Attorney General opinion from 1986, Opinion No. 86-5, quotes both the old language and the "1978 amendment." The current text says "the people have the right to keep and bear arms, which right shall not be abridged." It then lists what the Legislature may still do: regulate carrying concealed weapons, set minimum sentences for crimes committed with a firearm, penalize felons who possess firearms and punish the use of a firearm. It closes with two flat prohibitions: "No law shall impose licensure, registration or special taxation on the ownership or possession of firearms or ammunition. Nor shall any law permit the confiscation of firearms, except those actually used in the commission of a felony."

Those last two sentences go well beyond the Second Amendment's text, which says nothing about licensing, registration or taxes. In Opinion 86-5, the Attorney General applied the licensing ban to a fish and game statute about uncased firearms in the field and concluded the statute survived because it punished hunting conduct, not mere possession. For the federal side, see the site's Second Amendment course.

Sections 6, 7, 8 and 13: rights of the accused

Several sections track federal criminal procedure rights, with Idaho twists:

  • Section 6 guarantees bail "by sufficient sureties, except for capital offenses, where the proof is evident or the presumption great," and bans excessive bail, excessive fines and cruel and unusual punishments.
  • Section 7 says jury trial "shall remain inviolate," but allows three-fourths of a civil jury to return a verdict, lets the Legislature allow five-sixths verdicts in misdemeanor cases and caps misdemeanor juries in lower courts at six. The federal Seventh Amendment has no such details.
  • Section 8 allows felony charges by grand jury indictment or by a prosecutor's "information" after a magistrate's commitment, and says that once a grand jury has refused to indict, the prosecutor may not proceed by information. The federal Fifth Amendment, by contrast, requires a grand jury indictment for serious federal crimes.
  • Section 13 guarantees a "speedy and public trial," compulsory process for witnesses, the right to appear "in person and with counsel," protection from double jeopardy and self-incrimination, and that no person shall "be deprived of life, liberty or property without due process of law."

Section 13's due process clause uses nearly the same words as the Fifth and Fourteenth Amendments. When a claim depends on an unnamed fundamental right, though, the Planned Parenthood decision points the analysis to Section 1 and its 1889 history.

Section 17: where Idaho goes further

Article I, Section 17 reads almost like the Fourth Amendment: "The right of the people to be secure in their persons, houses, papers and effects against unreasonable searches and seizures shall not be violated; and no warrant shall issue without probable cause shown by affidavit, particularly describing the place to be searched and the person or thing to be seized." (Note one difference: the federal text says probable cause "supported by Oath or affirmation"; Idaho's says "shown by affidavit.") Despite the similar words, the Idaho Supreme Court has repeatedly read Section 17 to give more protection than the federal courts give under the Fourth Amendment.

No "good faith" exception: State v. Guzman (1992)

In United States v. Leon, 468 U.S. 897 (1984), the U.S. Supreme Court created a "good faith" exception to the exclusionary rule: evidence seized under a warrant later found invalid can still be used if officers reasonably relied on the warrant. In State v. Guzman, 122 Idaho 981, 842 P.2d 660 (1992), a Twin Falls County case in which officers found about 36 pounds of marijuana in a locked freezer, the Idaho Supreme Court refused to follow Leon under the state constitution. Justice Bistline's lead opinion called the exception "ill-conceived" and said it "cannot be reconciled with art. 1, § 17 of our state constitution." The court also abandoned an earlier Idaho decision that had embraced Leon.

Twenty years later the State asked the court to reconsider. In State v. Koivu, 152 Idaho 511, 272 P.3d 483 (2012), the court unanimously declined: "Because the State has not shown any ground for doing so, we decline to overrule that case." Evidence found after an arrest on a mistakenly issued warrant stayed suppressed.

Example: State v. Clarke (2019) and the misdemeanor arrest rule

In Kootenai County, a sheriff's deputy in Hayden arrested a man named Clarke without a warrant for misdemeanor battery, an offense that had been committed outside the deputy's presence. A search incident to the arrest turned up drugs, and Clarke was convicted of drug possession charges. The trial court found the arrest permissible under both the Fourth Amendment and Article I, Section 17.

The Idaho Supreme Court unanimously reversed in State v. Clarke, 165 Idaho 393, 446 P.3d 451 (2019). Writing for the court, Justice Horton looked at the common law as it stood when Idaho adopted its constitution. Under that common law, officers could generally make warrantless misdemeanor arrests only for offenses committed in their presence, and the court found no decision from any state before 1889 holding otherwise. Because the framers would have understood Section 17 against that background, the court held that a warrantless arrest for a completed misdemeanor committed outside an officer's presence violates Article I, Section 17, even when the officer has probable cause. The court decided the case entirely on the Idaho Constitution.

In State v. Plata Iniguez, 526 P.3d 1003 (Idaho 2023), the court went a step further. An officer had made the same kind of arrest relying on a statute that seemed to authorize it. The State argued the evidence should come in because the officer's mistake of law was reasonable, a rule the U.S. Supreme Court accepts under the Fourth Amendment. Idaho's court declined to adopt that exception under Section 17, relying in part on its refusal in Koivu to adopt a good-faith exception.

Notice the method in Clarke. It is the same historical approach the court used in Planned Parenthood: ask what the words meant in 1889. In Clarke that history expanded a right; in Planned Parenthood it defeated a claimed right. The method is consistent even when the results point in different political directions.

Myth: Idaho's Declaration of Rights just repeats the federal Bill of Rights

Some sections do use similar words, but similar words do not mean identical rights. The Idaho Supreme Court interprets the Idaho Constitution for itself. Under Section 17 it has rejected the federal good-faith and reasonable-mistake-of-law exceptions and adopted a misdemeanor arrest rule the federal courts do not impose. Other sections have no federal counterpart at all: inalienable rights (Section 1), open courts (Section 18), crime victims' rights (Section 22) and hunting, fishing and trapping (Section 23). And some sections are worded to protect more than the federal text, like the bans on firearm licensing and registration in Section 11. The reverse is true too: Idaho courts can and sometimes do read a state provision the same as its federal twin. You have to check the cases section by section.

Sections 14, 18, 19 and 20: Idaho-specific guarantees

Section 14 requires "just compensation" when private property is taken for public use, like the federal takings clause. But it also declares a long list of uses to be public uses, including reservoirs, irrigation canals, mine drainage, tramways and "any other use necessary to the complete development of the material resources of the state." That reflects the mining and irrigation economy of 1889 (Lesson 1).

Section 18 promises that "courts of justice shall be open to every person, and a speedy remedy afforded for every injury of person, property or character." Section 19 forbids any power, "civil or military," from interfering with "the free and lawful exercise of the right of suffrage." Section 20 bars property qualifications for voting or holding office, with exceptions for school elections, elections creating debt and irrigation district elections, where the Legislature may limit voting to landowners. The irrigation district exception was not in the 1889 text; it was added later.

Section 22: crime victims' rights (1994)

Idaho added Section 22 by a vote of the people. According to an article by Ada County Prosecutor Jan Bennetts published by the Idaho State Bar, the Legislature adopted House Joint Resolution 16 in 1994 (the House on February 21 and the Senate on March 9), and voters approved it on November 8, 1994, with 79.3 percent of the vote. The Attorney General's office describes the measure as the Victims Rights Amendment ratified in November 1994 in its guide to victims' rights.

Section 22 gives a crime victim, "as defined by statute," ten rights, including to be "treated with fairness, respect, dignity and privacy," to timely disposition of the case, to notice of and presence at criminal proceedings, to be heard at plea, sentencing and release proceedings, to restitution and to refuse an interview requested by the defense. It also contains important limits. A violation does not let a court dismiss a case or set aside a conviction, and it does not create a lawsuit for money damages. The section is "self-enacting," and the Legislature may pass laws to "define, implement, preserve, and expand" the rights.

Section 23: hunting, fishing and trapping (2012)

The newest section came from House Joint Resolution 2 of 2012. The House adopted it 63 to 4 (with 3 absent or excused) on March 22, 2012, and the Senate 31 to 3 (1 absent or excused) on March 27. Voters approved it that November; Boise State Public Radio reported about 74 percent support in early returns.

Section 23 declares that the rights to hunt, fish and trap, "including by the use of traditional methods," are "a valued part of the heritage of the State of Idaho and shall forever be preserved for the people," and that public hunting, fishing and trapping "shall be a preferred means of managing wildlife." Read the limits as carefully as the right. The section does not create a right to trespass, does not affect water rights or require minimum stream flows, does not diminish other private rights and does not stop the state from suspending or revoking a license under a statute. It also says these activities are "managed through the laws, rules and proclamations" of the state, so Fish and Game regulation continues.

How to: raise or evaluate an Idaho Constitution rights claim

  1. Name the exact section. "My rights were violated" is not an argument. "Article I, Section 17 of the Idaho Constitution" is.
  2. Read the current text and the 1889 text side by side. If the section was amended (Sections 7, 11 and 20, for example), find out when and what changed.
  3. Argue the Idaho provision separately from the federal one. If you only cite the Fourth Amendment, a court has no reason to consider whether Section 17 gives more. Explain why Idaho's text, history or precedent supports a different result.
  4. Find the leading Idaho cases. For search and seizure, start with Guzman, Koivu, Clarke and Plata Iniguez, then search for later opinions citing them.
  5. Bring history. After Planned Parenthood and Clarke, the Idaho Supreme Court asks what the words meant when adopted. For original sections, that means territorial law, 1889 common law and the convention debates. For later sections, look at the joint resolution, its statement of purpose and the voter pamphlet.
  6. Check the limits written into the section itself. Sections 11, 22 and 23 all say what they do not do.
  7. Remember that this is civic education, not legal advice.

If you report on this

When a court ruling or a lawsuit relies on "the Idaho Constitution," find out which section and whether the court decided the case on state grounds, federal grounds or both. That determines whether the U.S. Supreme Court could ever review it. Quote holdings from the opinion itself, and do not confuse a dissent with the court's ruling: in Planned Parenthood, the dissents argued for an abortion right, but the majority rejected it. Be precise about what a case decided. Clarke did not ban all warrantless arrests; it addressed completed misdemeanors outside an officer's presence. Describe ballot measures neutrally: Proposition 1 in 2026 is a citizen initiative to change state statutes, while HJR 4 and HJR 6 are legislatively referred constitutional amendments. And when you write about Section 22, remember that victims have rights to notice and to be heard, but a violation does not undo a conviction.
